Examples with DataBuffer java.awt.image.DataBuffer used on opensource projects

Example 1 with DataBuffer

use of java.awt.image.DataBuffer in project jna by java-native-access.

the class RasterRangesUtils method outputOccupiedRanges.

/**
     * Outputs ranges of occupied pixels.
     * In a raster that has an alpha layer, a pixel is occupied if its alpha value is not null.
     * In a raster without alpha layer, a pixel is occupied if it is not completely black.
     * @param raster image to be segmented in non black or non-transparent ranges
     * @param out destination of the non null ranges
     * @return true if the output succeeded, false otherwise
