Fields

device

Discussion

Device-specific information that QuickDraw uses to achieve the best possible results when drawing text in the graphics port. There may be physical differences in the same logical font for different output devices, to ensure the highest-quality printing on the device being used. The default value of the device field is 0, indicating the computer screen.

portPixMap

Discussion

A handle to a PixMap structure, which describes the pixels in this color graphics port.

portVersion

Discussion

The highest 2 bits are permanently set to indicate that this is a CGrafPort structure and the remainder of the field contains the version number of Macintosh Color QuickDraw that created this structure. Currently initialized to 0xC000.

grafVars

Discussion

A handle to a GrafVars structure that contains additional graphics fields of color information. On initialization, black is assigned to the rgbOpColor field of this structure, the default highlight color is assigned to the rgbHiliteColor field, and all other fields are set to 0. For information about the GrafVars structure, see Inside Macintosh: Imaging With QuickDraw.

chExtra

Discussion

A number by which to widen every character, excluding spaces, in a line of text. This value is used in proportional spacing. The value in this field is in 4.12 fractional notation: 4 bits of signed integer followed by 12 bits of fraction. This value is multiplied by the value in the txSize field before it is used. By default, this field contains 0.

pnLocHFrac

Discussion

The fractional horizontal pen position used when drawing text. The value in this field represents the low word of type Fixed; in decimal, its initial value is 0.5.

portRect

Discussion

The port rectangle that defines a subset of the pixel map to be used for drawing. All drawing done by the application occurs inside the port rectangle. The port rectangle (also called the content region) uses the local coordinate system defined by the boundary rectangle in the portPixMap field of the PixMap structure. The upper-left corner (which for a window is called the window origin) of the port rectangle usually has vertical and horizontal coordinates of 0. The port rectangle usually falls within the boundary rectangle, but it's not required to do so.

visRgn

Discussion

The region of the graphics port that's actually visible on the screen; that is, the part of the window that's not covered by other windows. By default, the visible region is equivalent to the port rectangle. The visible region has no effect on images that aren't displayed on the screen.

clipRgn

Discussion

A handle to the graphics port's clipping region, an arbitrary region that you can use to limit drawing to any region within the port rectangle. Unlike the visible region, the clipping region affects the image even if it isn't displayed on the screen. Initially the clip region is set to the rectangle -32768, -32768, 32767, 32767.

bkPixPat

Discussion

A handle to a PixPat structure that describes the background pixel pattern, initially set to white.

rgbFgColor

Discussion

An RGBColor structure that defines the requested foreground color. By default, the foreground color is black.

rgbBkColor

Discussion

An RGBColor structure that defines the requested background color. By default, the background color is white.

pnLoc

Discussion

The point where QuickTime will begin drawing the next line, shape, or character. It can be anywhere on the coordinate plane; there are no restrictions on the movement or placement of the pen. The location of the graphics pen is a point in the graphics port's coordinate system, not a pixel in a pixel image. The upper-left corner of the pen is at the pen location; the graphics pen hangs below and to the right of this point. This field is initialized to 0,0.

pnSize

Discussion

The vertical height and horizontal width of the graphics pen. The default size is a 1-by-1 pixel square; the vertical height and horizontal width can range from 0 by 0 to 32,767 by 32,767. If either the pen width or the pen height is 0, the pen does not draw. Heights or widths of less than 0 are undefined.

pnMode

Discussion

The pattern mode, a Boolean operation that determines the how QuickTime transfers the pen pattern to the pixel map during drawing operations. See Graphics Transfer Modes. When the graphics pen draws into a pixel map, QuickTime first determines what pixels in the pixel image are affected and finds their corresponding pixels in the pen pattern. It then does a pixel-by-pixel comparison based on the pattern mode, which specifies one of eight Boolean transfer operations to perform. QuickTime stores the resulting pixel in its proper place in the image. This field is initially set to patCopy.

pnPixPat

Discussion

A handle to a PixPat structure that describes a pixel pattern that can be used like the ink in the graphics pen. This field is initially set to black.

fillPixPat

Discussion

A handle to a PixPat structure that describes the pixel pattern that's used to fill an area. This field is initially set to black. Notice that this is not in the same location as the fillPat field in the GrafPort structure.

pnVis

Discussion

The graphics pen's visibility; that is, whether or not it draws on the screen. This field is initially set to 0 (visible).

txFont

Discussion

A font number that identifies the font to be used in the graphics port. This field is initially set to 0, indicating the system font.

txFace

Discussion

The character style of the text, with values from the set defined by the Style type, which includes such styles as bold, italic, and shaded. You can apply stylistic variations either alone or in combination. This field is initially set to plain text.

txMode

Discussion

One of three Boolean source mode constants (see below) that determines the way characters are placed in the bit image. This mode functions much like a pattern mode specified in the pnMode field; when drawing a character, QuickTime determines which pixels in the image are affected, does a pixel-by-pixel comparison based on the mode, and stores the resulting pixels in the image. This field is initially set to srcOr. See these constants:

txSize

Discussion

The text size in pixels. QuickTime uses this information to provide the bitmaps for text drawing. The txSize value can be represented by the formula (size in points) x (device resolution) / 72 dpi. This field is initially set to the system font size.

spExtra

Discussion

A number equal to the average number of pixels by which each space character should be widened to fill out a fully justified text line. This field is useful when a line of characters is to be aligned with both the left and the right margin. This field is initially set to 0.

fgColor

Discussion

The pixel value of the foreground color. This is the best available approximation in the color lookup table (CLUT) to the color specified in the rgbFgColor field. This field is initially set to blackColor; see Color Constants.

bkColor

Discussion

The pixel value of the background color. This is the best available approximation in the color lookup table (CLUT) to the color specified in the rgbBkColor field. This field is initially set to whiteColor; see Color Constants.

colrBit

Discussion

Reserved and set to 0.

patStretch

Discussion

A value, initially set to 0, used during output to a printer to expand patterns if necessary. Your application should not change this value.

picSave

Discussion

A handle to the state of the Macintosh picture definition. If no picture is open, this field contains NIL; otherwise it contains a handle to information related to the picture definition. Your application shouldn't be concerned about exactly what information the handle leads to; you may, however, save the current value of this field, set the field to NIL to disable the picture definition, and later restore it to the saved value to resume defining the picture.

rgnSave

Discussion

A handle to the state of the region definition. If no region is open, this field contains NIL; otherwise it contains a handle to information related to the region definition. Your application shouldn't be concerned about exactly what information the handle leads to; you may, however, save the current value of this field, set the field to NIL to disable the region definition, and later restore it to the saved value to resume defining the region.

polySave

Discussion

A handle to the state of the polygon definition. If no polygon is open, this field contains NIL; otherwise it contains a handle to information related to the polygon definition. Your application shouldn't be concerned about exactly what information the handle leads to; you may, however, save the current value of this field, set the field to NIL to disable the polygon definition, and later restore it to the saved value to resume defining the polygon.

grafProcs

Discussion

An optional pointer to a CQDProcs structure that your application can store into if you want to customize Color QuickDraw drawing routines or use Color QuickDraw in other advanced, highly specialized ways. This field is initially set to NIL.

Discussion

You can have many graphics ports open at once; each one has its own local coordinate system, pen pattern, background pattern, pen size and location, font and font style, and pixel map in which drawing takes place. Several fields in this structure define your application's drawing area. All drawing in a graphics port occurs in the intersection of the graphics port's boundary rectangle and its port rectangle. Within that intersection, all drawing is cropped to the graphics port's visible region and its clipping region.

Version Notes

The CGrafPort structure supersedes the earlier GrafPort structure.

struct CodecInfo {
   Str31             typeName;
   short             version;
   short             revisionLevel;
   long              vendor;
   long              decompressFlags;
   long              compressFlags;
   long              formatFlags;
   UInt8             compressionAccuracy;
   UInt8             decompressionAccuracy;
   unsigned short    compressionSpeed;
   unsigned short    decompressionSpeed;
   UInt8             compressionLevel;
   UInt8             resvd;
   short             minimumHeight;
   short             minimumWidth;
   short             decompressPipelineLatency;
   short             compressPipelineLatency;
   long              privateData;
};

Fields

typeName

Discussion

Indicates the compression algorithm used by the component; for example, 'Animation'. This Pascal string may be used to identify the compression algorithm to the user. The string always takes up 32 bytes no matter how long it is. The 32 bytes consist of 31 bytes plus one length byte. Apple assigns these type names. The value of this field should correspond to the value of the typeName field in the appropriate compressor name structure returned by GetCodecNameList.

version

Discussion

Indicates the version of compressed data this component supports. The contents of this field should indicate the most recent version of the compression algorithm that the component can understand.

revisionLevel

Discussion

Indicates the version of the component; for example, 0x00010001 (1.0.1). Developers of compressors assign these version numbers.

vendor

Discussion

Identifies the developer of the component; for example, 'appl'. The value of this field corresponds to the manufacturer code or application signature assigned to the developer.

decompressFlags

Discussion

Contains flags (see below) that specify the decompression capabilities of the component. Typically, these flags are of interest only to developers of image decompressors. See these constants:

• codecInfoDoes1

• codecInfoDoes2

• codecInfoDoes4

• codecInfoDoes8

• codecInfoDoes16

• codecInfoDoes32

• codecInfoDoesDither

• codecInfoDoesStretch

• codecInfoDoesShrink

compressFlags

Discussion

Contains flags (see below) that specify the compression capabilities of the component. Typically, these flags are of interest only to developers of image compressors.

formatFlags

Discussion

Contains flags (see below) that describe the possible format for compressed data produced by this component and the format of compressed files that the component can handle during decompression. Typically, these flags are of interest only to developers of compressor components. See these constants:

• codecInfoDepth1

• codecInfoDepth2

• codecInfoDepth4

• codecInfoDepth8

• codecInfoDepth16

• codecInfoDepth24

• codecInfoDepth32

• codecInfoDepth33

• codecInfoDepth34

• codecInfoDepth36

• codecInfoDepth40

• codecInfoStoresClut

• codecInfoDoesLossless

• codecInfoSequenceSensitive

compressionAccuracy

Discussion

Indicates the relative accuracy of the compression algorithm employed by the component. Valid values for this field range from 0 to 255. A value of 0 means that the accuracy is unknown. Values from 1 to 255 provide a gauge for the relative accuracy of the compression algorithm; higher values indicate better accuracy. The Image Compression Manager examines this field to determine which compressor component can most accurately compress a given image. The compressionAccuracy field can only approximate the accuracy of a compression algorithm. Typically, compression algorithms produce results of varying quality based on a variety of parameters, including image size and content. Since this information is not available until a compression request is issued, a precise measure of accuracy is not possible. However, the value of this field should still give a rough idea of the accuracy of the supported algorithm.

decompressionAccuracy

Discussion

Indicates the relative accuracy of the decompression algorithm employed by the component. Valid values for this field range from 0 to 255. A value of 0 means that the accuracy is unknown. Values from 1 to 255 indicate the relative accuracy of the decompression technique; higher values mean better accuracy. The Image Compression Manager examines this field to determine which decompressor component can most accurately decompress a given image. The decompressionAccuracy field can only approximate the accuracy of a decompression algorithm. Typically, decompression algorithms produce results of varying quality based on a variety of parameters, including image size and content. Since this information is not available until a decompression request is issued, a precise measure of accuracy is not possible. However, the value of this field should still give a rough idea of the accuracy of the supported algorithm.

compressionSpeed

Discussion

Indicates the relative speed of the component for compression operations. Valid values for this field lie in the range from 0 to 65,535. A value of 0 means that the speed is unknown. Values from 1 to 65,535 correspond to the number of milliseconds the component requires to compress a 320-by-240 pixel image on a Macintosh II computer. The Image Compression Manager examines this field to determine which compressor component can most quickly compress a given image.

decompressionSpeed

Discussion

Indicates the relative speed of the component for decompression operations. Valid values for this field lie in the range from 0 to 65,535. A value of 0 means that the speed is unknown. Values from 1 to 65,535 correspond to the number of milliseconds the component requires to decompress a 320-by-240 pixel image on a Macintosh II computer. The Image Compression Manager examines this field to determine which compressor component can most quickly decompress a given image.

compressionLevel

Discussion

Indicates the relative compression achieved by this component. Valid values for this field lie in the range from 0 to 255. A value of 0 means that the compression level is unknown. Values from 1 to 255 map to percentage values of relative compression; lower values mean lesser compression. A value of 1 means no compression (0 percent); a value of 255 means maximum compression (100 percent). The Image Compression Manager examines this field to determine which available compressor component will yield the smallest resulting data for a given image. The compressionLevel field can only approximate the effectiveness of a compression algorithm. Typically, compression algorithms produce results of varying quality based on a variety of parameters, including image size and content. Since this information is not available until a compression request is issued, a precise measure of compression is not possible. However, the value of this field should still give a rough idea of the effectiveness of the supported algorithm.

resvd

Discussion

Reserved; set to 0.

minimumHeight

Discussion

Specifies the height in pixels of the smallest image the component can handle. Together with the minimumWidth field, this field defines the block size for the component. The Image Compression Manager does not issue compression or decompression requests for images smaller than the block size.

minimumWidth

Discussion

Specifies the width in pixels of the smallest image the component can handle. Together with the minimumHeight field, this field defines the block size for the component. The Image Compression Manager does not issue compression or decompression requests for images smaller than the block size.

decompressPipelineLatency

Discussion

Decompression pipeline latency in milliseconds, for asynchronous codecs.

compressPipelineLatency

Discussion

Compression pipeline latency in milliseconds, for asynchronous codecs.

privateData

Discussion

Reserved for future use. This field must be set to 0.

Discussion

EventRecord

Contains information about a retrieved Mac OS event.

struct EventRecord {
   EventKind         what;
   UInt32            message;
   UInt32            when;
   Point             where;
   EventModifiers    modifiers;
};

Fields

what

Discussion

A constant (see below) that specifies the kind of event. See these constants:

message

Discussion

Additional information (see below) associated with the event. The interpretation of this information depends on the event type. See these constants:

when

Discussion

The time when the event was posted, in ticks since system startup.

where

Discussion

For low-level events and operating-system events, this field contains the location of the cursor at the time the event was posted (in global coordinates). For high-level events, it contains a second event specifier, the event ID. The event ID defines the particular type of event within the class of events defined by the message field of the high-level event. For high-level events, you should interpret the where field as having the data type OSType, not Point.

modifiers

Discussion

Contains information about the state of the modifier keys and the mouse button at the time the event was posted. For activate events, this field also indicates whether the window should be activated or deactivated. In System 7 it also indicates whether the mouse-down event caused your application to switch to the foreground. Each modifier key is represented by a specific bit in the modifiers field of the event record structure. The modifier keys include the Option, Command, Caps Lock, Control, and Shift keys. If your application attaches special meaning to any of these keys in combination with other keys or when the mouse button is down, you can test the state of the modifiers field to determine the action your application should take. For example, you can use this information to determine whether the user pressed the Command key and another key to make a menu choice.

Fields

baseAddr

Discussion

For an onscreen pixel image, a pointer to the first byte of the image. For optimal performance, this should be a multiple of 4. The baseAddr field of the PixMap record for an offscreen graphics world contains a handle instead of a pointer. Your application should never directly access the baseAddr field of the PixMap record for an offscreen graphics world.

rowBytes

Discussion

The offset in bytes from one row of the image to the next. The value must be even, less than 0x4000, and for best performance it should be a multiple of 4. The high 2 bits of rowBytes are used as flags. If bit 15 =1, the data structure pointed to is a PixMap structure; otherwise it is a BitMap structure.

bounds

Discussion

The boundary rectangle, which links the local coordinate system of a graphics port to QuickDraw's global coordinate system and defines the area of the bit image into which QuickDraw can draw. By default, the boundary rectangle is the entire main screen. Do not use the value of this field to determine the size of the screen; instead use the value of the gdRect field of the GDevice structure for the screen.

pmVersion

Discussion

The version number of Color QuickDraw that created this PixMap structure. The value of pmVersion is normally 0. If pmVersion is 4, Color QuickDraw treats the PixMap record's baseAddr field as 32-bit clean. All other flags are private. Most applications never need to set this field

packType

Discussion

The packing algorithm used to compress image data. Color QuickDraw currently supports a packType of 0, which means no packing, and values of 1 to 4 for packing direct pixels.

packSize

Discussion

The size of the packed image in bytes. When the packType field contains the value 0, this field is always set to 0.

hRes

Discussion

The horizontal resolution of the pixel image in pixels per inch. By default, this value is 0x00480000 (for 72 pixels per inch).

vRes

Discussion

The vertical resolution of the pixel image in pixels per inch. By default, this value is 0x00480000 (for 72 pixels per inch).

pixelType

Discussion

The storage format for a pixel image. Indexed pixels are indicated by a value of 0. Direct pixels are specified by a value of RGBDirect, or 16. In the PixMap record of the GDevice structure for a direct device, this field is set to RGBDirect when the screen depth is set.

pixelSize

Discussion

The number of bits used to represent a pixel. Indexed pixels can have sizes of 1, 2, 4, and 8 bits; direct pixel sizes are 16 and 32 bits.

cmpCount

Discussion

The number of components used to represent a color for a pixel. With indexed pixels, each pixel is a single value representing an index in a color table, and therefore this field contains the value 1; the index is the single component. With direct pixels, each pixel contains three components (one integer each for the intensities of red, green, and blue) so this field contains the value 3.

cmpSize

Discussion

The size in bits of each component for a pixel. Color QuickDraw expects that the sizes of all components are the same, and that the value of the cmpCount field multiplied by the value of the cmpSize field is less than or equal to the value in the pixelSize field.

For an indexed pixel value, which has only one component, the value of the cmpSize field is the same as the value of the pixelSize field; that is, 1, 2, 4, or 8. For direct pixels there are two additional possibilities. A 16-bit pixel, which has three components, has a cmpSize value of 5; this leaves an unused high-order bit, which Color QuickDraw sets to 0. A 32-bit pixel, which has three components (red, green, and blue), has a cmpSize value of 8; this leaves an unused high-order byte, which Color QuickDraw sets to 0.

If presented with a 32-bit image (for example, in the CopyBits procedure) Color QuickDraw passes whatever bits are there, and it does not set the high byte to 0. Generally, therefore, your application should clear the memory for the image to 0 before creating a 16-bit or 32-bit image.

planeBytes

Discussion

The offset in bytes from one drawing plane to the next. This field is set to 0.

pmTable

Discussion

A handle to a ColorTable structure for the colors in this pixel map.

pmReserved

Discussion

Reserved. This field must be set to 0 for future compatibility.

pixelFormat

Discussion

The way the pixels are arranged; see Pixel Formats.

pmTable

Discussion

Color map for this structure.

pmExt

Discussion

Handle to a PixMapExtension structure. Set to NIL if there is no extension.

Discussion

The pixel map for a window's color graphics port always consists of the pixel depth, color table, and boundary rectangle of the main screen, even if the window is created on or moved to an entirely different screen.

TimeRecord

Contains a time value with its scale and time base.

struct TimeRecord {
   CompTimeValue    value;
   TimeScale        scale;
   TimeBase         base;
};

Fields

value

Discussion

Contains the time value. The time value defines either a duration or an absolute time by specifying the corresponding number of units of time. For durations, this is the number of time units in the period. For an absolute time, this is the number of time units since the beginning of the time coordinate system. The unit for this value is defined by the scale field. The time value is expressed as a 64-bit integer quantity. This 64-bit quantity consists of two 32-bit integers and is defined by the Int64 data type.

scale

Discussion

Contains the time scale. This field specifies the number of units of time that pass each second. If you specify a value of 0, the time base uses its natural time scale.

base

Discussion

Contains a reference to the time base. You obtain a time base by calling GetMovieTimeBase or NewTimeBase. If the time structure defines a duration, set this field to NIL. Otherwise, this field must refer to a valid time base.

If neither of the instruments specified by the instrumentNumber or gmNumber fields is available, the instrument specified by the instrumentName field is used. Finally, if none of these fields specifies an instrument that is available, no tone is played.

gmNumber

Discussion

The instrument number of a General MIDI or GS instrument to use if the instrument specified by the instrumentNumber field is not available. This value, which must be in the range 1-16383, can specify only General MIDI and GS instruments. The instrument specified by the instrumentNumber field is used if it is available; if not, the instrument specified by the gmNumber field is used. If neither of the instruments specified by the instrumentNumber or gmNumber fields is available, the instrument specified by the instrumentName field is used. Finally, if none of these fields specifies an instrument that is available, no tone is played.
