An NSEPSImageRep object can render an image from encapsulated PostScript (EPS) code.

Tasks

Creating an NSEPSImageRep

Getting Image Data

Drawing the Image

Class Methods

Creates and returns an NSEPSImageRep object initialized with the specified EPS data.

+ (id)imageRepWithData:(NSData *)epsData

Parameters
epsData

The EPS data representing the desired image.

Return Value

A new, initialized NSEPSImageRep object or nil if the object could not be initialized.

Discussion

The size of the receiver is set using the bounding box information specified in the EPS header comments.

prepareGState

Implemented by subclasses to configure the graphics state prior to drawing.

- (void)prepareGState

Discussion

The draw method of NSEPSImageRep sends this message to itself just before rendering the EPS code. The default implementation of this method does nothing. You can override it in your subclass to prepare the graphics state as needed.
