I'm trying to read an image with PIL, crop several subimages out of it, and try to combine the subimages again into a combined new one. This is a test script, later I want to only several single images into a combined one.
I have to work with 16-bit color windows bitmaps in BMP format. My input image (input.bmp) IS a 16-color bmp. The cropped images that the script saves are saved in 8-bit/256-color format; they look correct. The combined image is also saved in 8-bit/256-color format, but it is all black - maybe the palette is missing? Anyway, I cannot use 256-color images. How do I save the images in 4-bit/16-color format? Thanks, Thomas Here is the code; I'm using Python 2.4 and PIL 1.5: <code> import Image img = Image.open("input.bmp") w, h = img.size print img.size, img.mode newimg = Image.new("P", (16*30, 15)) x = 0 i = 1 while x < w: this = img.crop((x, 0, x+16, 15)) this.save("%02d.bmp" % i) newimg.paste(this, (x, 0, x+16, 15)) x += 16 i += 1 newimg.save("output.bmp") <code/> -- http://mail.python.org/mailman/listinfo/python-list
