Hi,
In my project I have some functions, like perspective correction, image stretching and fisheye unwrapping. I've implemented bilinear and bicubic filter, but I'd like to give more choice for users :)
I need to access resampling function at pixel level.
Could it be possible to add a function for this?
Something like
Since x,y are float, it should return in *value interpolated rgb values for this coordinates, using specified filter. Something like here for bilinear interpolation: http://en.wikipedia.org/wiki/Bilinear_interpolation
FreeImage has implemented several filters, so maybe they could be used this way.
I have to look into source code od rescale function to see, if it can be done easily (maybe not) :)

Something like
DLL_API BOOL DLL_CALLCONV FreeImage_GetPixelResampled(FIBITMAP *dib, float x, float y, RGBQUAD * value, FREE_IMAGE_FILTER filter FI_DEFAULT(FILTER_CATMULLROM));

Hi,
What this function is supposed to do ?
