Method Details

convertRenderedImageToData

public static void convertRenderedImageToData(RenderedImage img,
 int[] targetArray,
 int startOffset)

Utility method for MFImageWrapper and SFImageWrapper to convert a RenderedImage to the SFImage integer format

Parameters:

img - The rendered image to convert

targetArray - The integer array to place the data in

startOffset - Starting offset in array

convertSubRenderedImageToData

public static void convertSubRenderedImageToData(RenderedImage img,
 int[] targetArray,
 int startOffset,
 int srcWidth,
 int srcHeight,
 int srcXOffset,
 int srcYOffset,
 int destXOffset,
 int destYOffset)

Perform a bitBlt from a source image to an SFImage field. Does not do wrapping.

Parameters:

img - The image the sample is taken from

targetArray - The array containing the target field

startOffset - The index where the target field starts

srcWidth - The width of the sub image to copy

srcHeight - The height of the sub image to copy

srcXOffset - The X offset of the sub image to copy

srcYOffset - The Y offset of the sub image to copy

destXOffset - The destination X offset

destYOffset - The destination Y offset

convertDataToRenderedImage

public static WritableRenderedImage convertDataToRenderedImage(int width,
 int height,
 int components,
 int[] pixels)

Utility method to convert SFImage data representation to a WritableRenderedImage

Parameters:

width - The image width

height - The image height

components - The number of components per pixel

pixels - The array of pixel data

Returns:
