Image Processing Library
	I'm interested in image processing. Here is what I've done including all my source codes.
	Image Processing Library Source Code
	Download Download ZIP (218k) Brief Introduction 32bits ANSI C compatible code Supported image file formats: PNG, JPEG, BMP, GIF,PCX, TGA, TIFF, Raw Data Features: * color quantization and color to grayscale conversion. * image flatten with alpha, transparency and background support. * image drawing operations as draw line, draw pixel and advanced bitbilt operations including both alpha and transparent support. * geometry transformations as resample, rotate, flip, mirror, affine, projective and rectangler to cylinder. * filterings as blur, sharpen, median, Sobel edge... * special effects and histogram operations as mosaic, threshold, negtive, contrast expand, histogram equalization, brighten and color saturation adjust. * edge detection and binary image operation as 4-conn and 8-conn edge tracing, edge thinning, area shrink, area expand, noise reduction. Please check readme for more information.
