For instance an image that must be displayed on screen will have its pixel data copied to the big buffer, then when using OpenCL the updated parts of that buffer will be copied to the GPU so that a GPU-side mirror of this buffer is maintained and the image can be displayed using the...
The specific color information that a pixel describes is some blend of three components of the color spectrum -- RGB. Up to three bytes of data are allocated to specify a pixel's color, one byte for each major color component. A true color or 24-bit color system uses all three bytes. ...

The channel-of-interest number can be either 1, 2, or 3. Select-Channel Destination-Image Pointer This is a pointer to the channel-of-interest within the first pixel of the destination image. E.g. ifpDstis the pointer to the first pixel inside the ROI of a three channel image. Us...
If you have aPmode image, that means it is palettised. That means there is a palette with up to 256 different colours in it, and instead of storing 3 bytes for R, G and B for each pixel, you store 1 byte which is the index into the palette. This confers both advantages...
height) is located. The “start pixel” of the ROI is implicitly given by the image-data pointer. I.e. instead of explicitly passing a pixel coordinate for the upper-left corner (lowest memory address), the user simply offsets the image-data pointers to point to the first pixel of the...
