List of countPixels() Examples

Examples of countPixels()

com.lightcrafts.mediax.jai.Histogram.countPixels()
Accumulates the histogram of the pixels within a specific region-of-interest (ROI) by counting them based on the indicated horizontal and vertical sampling period. The result is stored in the bins array and may be obtained by calling the getBins method.
The ROI specifies the region within which the pixels are counted. If it is null, the entire Raster is counted. If it is not null and does not intersect with the Raster, then this method returns without changing the bins.
The set of pixels to be counted may be obtained by intersecting the grid (xStart + i * xPeriod, yStart + j * yPeriod); i, j >= 0 with the ROI and the bounding rectangle of the Raster. @param raster The Raster that contains the pixels to be counted. @param roi The region-of-interest within which the pixels are counted. @param xStart The initial X sample coordinate. @param yStart The initial Y sample coordinate. @param xPeriod The X sampling period. @param yPeriod The Y sampling period. @throws IllegalArgumentException If raster isnull. @throws IllegalArgumentException If the pixels stored in theraster do not have the same number of bands (samples per pixel) as this histogram's bins. @thows RuntimeException if the data type is not supported(not in DataBuffer.TYPE_BYTE,..., DataBuff.TYPE_DOUBLE.
