I would like to take one bright spot in one of these rectangular regions to alter my colors in the other layer using the same spot. LoHalo, NoHalo Halo is an artifact that can be created by interpolation. This usually gives a good result, but it naturally takes more time. The thing rectangle on the right side of the left image, and the thin rectangle on the left side of the right image will overlap when put together. The color of each pixel is computed as the average color of the eight closest pixels in the original image. Second image are two overlapping layers I separated. It spans about 20 minutes with guided tips & techniques for anyone just learning the GIMP software. no white pixels there - there are only the black and alpha/black pixels.
You can see the change in color between the various overlapping layers. And a couple of clicks in GIMP, and I get an image with the White changed to. I was wondering if there is a method in GIMP to take a single pixel (or several) in the overlapping region from one layer and match it in the same pixel to an adjacent layer so that the entire color level of the adjacent layer matches the first layer based on that pixel selection?įirst image is my whole image with guides removed. All the work is performed with the Selection Tool. One might intuitively think you use the selection tool to select, and then hop over to the move tool to move. These images are taken at different focus depths because our slide holder is slightly bent (cannot get it fixed just yet) so the overlapping colors are slightly different. There are two tools being discussed: the Selection Tool and the Move Tool. I have set up grids so that I have perfect overlap between them. I have taken sequential images that overlap for anywhere between 20 - 50 pixels at the edges. I am putting together fluorescent images taken on a microscope.
