Hello, I am currently doing my thesis and I am using QT4, I have the following problem: I want to open an image (. Tiff), which has only one dimension, that is, in greyscale (band of a satellite, which is why only in one dimension), and I need to see it as a matrix for porder apply an algorithm, the problem is not how to do to see the values of the pixel in a matrix where the range of these pixel is 0-255, the image is 32-bit, I suppose we must transform to 8. thank you very much.
