I *did* create the images with Gimp, and they do have transparent backgrounds. (Did you view the image link I posted?)
I have used colorkeys in the past, but the problem here is that there are semi-transparent (not fully opaque) pixels in the images (again see the image I linked to), and when you draw these images to newly created surfaces (ie new = pygame.Surface(); new.blit(loadedimage)) the pixels are no longer transparent. Hence why I need to create surfaces with completely transparent backgrounds, instead of the default black. Here's my code for reference: import os import pygame from pygame.locals import * IMAGE_CACHE = {} def load_image(filename): if filename not in IMAGE_CACHE: img = pygame.image.load(os.path.join("data", filename)).convert_alpha() IMAGE_CACHE[filename] = img return IMAGE_CACHE[filename] def load_strip(filename, width): imgs = [] img = load_image(filename) for x in range(img.get_width()/width): *i = pygame.Surface((width, img.get_height()))*** *i.blit(img, (-x*width, 0))* imgs.append(i) return imgs Cheers, On Thu, Aug 20, 2009 at 9:05 PM, Henrique Nakashima < henrique.nakash...@gmail.com> wrote: > Transparency is often a problem because image editors and viewers not > always display the same sorts of transparency. > > To create a transparent background, load it from an image with > transparency.
