Constructor Detail

AdobePathWriter

public AdobePathWriter(Shape path)

Creates an AdobePathWriter for the given path.

NOTE: Photoshop paths are stored with the coordinates (0,0) representing the top left corner of the image, and (1,1) representing the bottom right corner, regardless of image dimensions.

Parameters:

path - A Shape instance that has WIND_EVEN_ODD rule, is contained within the rectangle [x=0.0,y=0.0,w=1.0,h=1.0], and is closed.

Throws:

IllegalArgumentException - if path is null, the paths winding rule is not @link Path2D#WIND_EVEN_ODD} or the paths bounding box is outside [x=0.0,y=0.0,w=1.0,h=1.0] or the path is not closed.

Method Detail

writePathResource

public void writePathResource(int resourceId,
                              DataOutput output)
                       throws IOException

Writes the path as a complete Adobe Photoshop clipping path resource to the given stream.

Parameters:

resourceId - the resource id, typically PSD.RES_CLIPPING_PATH (0x07D0).

output - the stream to write to.

Throws:

IOException - if an I/O exception happens during writing.

writePath

public void writePath(DataOutput output)
               throws IOException

Writes the path as a set of Adobe Photoshop path segments to the given stream.

Parameters:

output - the stream to write to.

Throws:

IOException - if an I/O exception happens during writing.

writePathResource

public byte[] writePathResource(int resourceId)

Transforms the path to a byte array, containing a complete Adobe Photoshop path resource.

Parameters:

resourceId - the resource id, typically PSD.RES_CLIPPING_PATH (0x07D0).

Returns:

a new byte array, containing the clipping path resource.

writePath

public byte[] writePath()

Transforms the path to a byte array, containing a set of Adobe Photoshop path segments.

Returns:

a new byte array, containing the path segments.
