writeImage

public static void writeImage(byte[] img,
                              java.awt.Dimension imgDim,
                              java.lang.String imgName,
                              java.awt.geom.Rectangle2D targetRect,
                              boolean isJPEG,
                              java.awt.color.ColorSpace colorSpace,
                              PSGenerator gen)
                       throws java.io.IOException

Writes a bitmap image to the PostScript stream.

Parameters:

img - the bitmap image as a byte array

imgDim - the dimensions of the image

imgName - the name of the image

targetRect - the target rectangle to place the image in

isJPEG - true if "img" contains a DCT-encoded images, false if "img" contains the decoded bitmap

colorSpace - the color space of the image

gen - the PostScript generator

Throws:

java.io.IOException - In case of an I/O exception

renderBitmapImage

public static void renderBitmapImage(java.awt.image.RenderedImage img,
                                     float x,
                                     float y,
                                     float w,
                                     float h,
                                     PSGenerator gen)
                              throws java.io.IOException

Renders a bitmap image to PostScript.

Parameters:

img - image to render

x - x position

y - y position

w - width

h - height

gen - PS generator

Throws:

java.io.IOException - In case of an I/O problem while rendering the image
