Method Detail

findImages

public int[] findImages(Image[] input,
                        Image output)

Find the best image for each output pixel.

Overrides:

findImages in class RectRecurse

Parameters:

input - An array of images that may be sampled to get the output image.

output - The output image. In this routine we are interested in its geometry, not its data.

Returns:

An index array which for each pixel in the output image gives the best image to sample. Note that this has dimension int[nx*ny] where nx changes most rapidly. The values of the index array can be:

• >= 0: The pixel is best indexed with the given image.
• -1: [internal] The best image for this pixel has not yet been determined.
• -2: This pixel is not on any of the input images.
• -3: This pixel does not represent a physical coordinate.
• -4: [in other methods] this pixel has already been processed.
