Python plug-in: ImageJ-stack-2-composedRGB for GIMP3

Software GIMP
1

Hi,
I have made a new python plug-in “ ImageJ-stack-2-composedRGB for GIMP3”.

ImageJ, known as scientific FOSS image editor, can export 16 or 32 bit RGB image files only as RGB stack TIFF format. (In other formats, ImageJ can export only 8bit (8 x 3 = 24bit) RGB image.) This format is not compatible with other image editing software, and in them this format is recognized as multi-image TIFF which has 3 gray-scale images or one gray-scale image TIFF.

This plug-in enable you to import ImageJ RGB stack TIFF as composed RGB xcf file in GIMP3.

Usage of this plug-in

  1. Run this plug-in from [File] menu in GIMP3.

  2. Select the RGB stack TIFF file, which you want to import.

  3. Finally, the file will be imported as composed RGB image.

This could prove a nice addition for GIMP. What sort of images are you stacking? I presume focus stacking, but I may be wrong.

It seems that my explanation is inadequate and causes some misunderstanding. ImageJ originally could only handle 8 bit RGB color images. Now ImageJ can handle 16 or 32 bit RGB color images, but it handles them a little tricky and causes some incompatibility with other image software. In ImageJ, a 16 or 32 bit color image is treated as a stack of three images: R, G, and B images. Therefore, when handling 16 or 32 bit RGB color images, I always stack my color channel image data in ImageJ.
