Image Filter Tester 1.1 - Generic Pixel Transfer Filter
This filter transforms an image using 3 user-defined functions.
The first two functions (called X/Y-Coordinate Transfer Functions) define how the pixel coordinates of the new image are mapped to the pixel coordinates of the original image. These two functions are functions of pixel coordinates.
The third function (called Pixel Value Transfer Function) calculates the pixel values of the new image. This function is a function of pixel coordinates and pixel value.
While you type your transfer functions, please use 'x0' and 'x1' to represent pixel coordinates, and 'x2' to represent pixel value. The parser is NOT case-sensitive. The origin of pixel coordinates is the top-left corner of the image.
The default pixel value is used when the pixel coordinates of the new image are mapped to the pixel coordinates outside the original image.
This filter works for grayscale images or 24-bit color images.
