Here are some examples.. vertex position passed to the the vertex shader does not solve the issue.

This isn't an affine transformation since lines are no longer parallel around the area of distortion etc. Is it possible using CGImage or would I need to do this using OpenGLES Thanks iphone image filter opengl es quartz..

Usually the gain is set a bit lower so that the maximum values aren't right on the edge of distortion.

How can i set volume with amplification in app with AVPlayer class? http://stackoverflow.com/questions/7444898/how-can-i-set-volume-with-amplification-in-app-with-avplayer-class link. You cannot set volume greater than 1.0 for AVPlayer. If you increase volume to a value more than 1.0 then the distortion of voice and disturbance will increase. But you need to check whats the output source of the player. Default is microphone..

How can you apply distortions to a UIImage using OpenGL ES? http://stackoverflow.com/questions/9886843/how-can-you-apply-distortions-to-a-uiimage-using-opengl-es can you apply distortions to a UIImage using OpenGL ES Is there any way to create effects like dents pinching twisting squashing etc. on a UIImage.. would be to use OpenGL ES 2.0 shaders. Once again if I might point you to my GPUImage framework it can do many of the distortion operations you describe. For those that are missing you can write your own fragment shaders. The effects I have in there.. For those that are missing you can write your own fragment shaders. The effects I have in there are a convex bulge distortion using a GPUImageBulgeDistortionFilter a concave distortion using an inverted scale parameter to the previous filter a swirl..
