These functions step through an ROI in a source buffer and map the source data into a destination ROI using x-y scaling factors and a specified method of interpolation.
The coordinates of the center pixel in the destination image are the same as the center coordinates of the center pixel in the source image.
The Resize function is a special case of this function with the image center set at (0,0).
The following interpolation modes are available.
FWI_INTER_NN: nearest neighbor interpolation FWI_INTER_LINEAR: linear interpolation FWI_INTER_CUBIC: cubic interpolation FWI_INTER_SUPER: supersampling FWI_INTER_LANCZOS: interpolation with Lanczos window function
Use the super-sampling interpolation option when both the x and y scaling factors are less than 1.
