Overview

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

Tasks

Creating an NSEPSImageRep

Getting Image Data

Drawing the Image

Class Methods

imageRepWithData:

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.

Availability
  • Available in OS X v10.0 and later.
Declared In

Instance Methods

boundingBox

Returns the rectangle that bounds the receiver.

- (NSRect)boundingBox
Return Value

The bounding box of the receiver. This rectangle is obtained from the “%%BoundingBox:” comment in the EPS header when the NSEPSImageRep object is initialized.

initWithData:

Returns an NSEPSImageRep object initialized with the specified EPS data.

- (id)initWithData:(NSData *)epsData
Parameters
epsData

The EPS data representing the desired image.

Return Value

The initialized NSEPSImageRep object or nil if the object could not be initialized

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.
