Image Processing And Manipulation

• Filters & effects - These functionalities include ROI processing, convolution matrix based filters and more than 100 effects and filters working in the native image bit-depth such as Median, Gaussian blur, Unsharp Mask, Despeckle, FloodFill, Red-eye removal, Background subtract, Emboss, Sharpen, Blur, Edge Detection and Twirl and Swirl. Adjust contrast, brightness and saturation as you wish. Full support for native 48-bit and 64-bit RGB(A) pixel format.
