Hi, I don't know Pygame that well and have never used subsurfaces
but it it looks kinda interesting. Would you do the subsurface
approach in the following way?
def load_strip(filename, width):
imgs = []
img = load_image(filename)
for x in range(img.get_width()/width):
i =
Hi,
I have a function that loads image
stripshttp://pymike.pynguins.com/downloads/player-run.pngand returns
the images in lists. To do this, I create new surfaces and blit
the strips to them at an offset.
My question is: Is there a way to create surfaces with transparent
backgrounds? The images
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.
Png supports it, but not all png editors do. I managed to get transparency
done by using GIMP
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
You need to convert the surface i with .convert_alpha(), as well.

Aha! Figured it out!
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())).convert_alpha()
i = i.convert_alpha()
i.fill((255,255,255,0))*
i.blit(img,
Aha.
There might be something weird about the image as well, because when I used
another one with a transparent background it worked as well - without
modifications to the code. Despite that, I couldn't find anything strange in
the png.

Hi pymike,
I don't understand what you are doing here. If you load an image with
per-pixel alpha, the returned surface will also have per-pixel alpha.
All convert_alpha() may do here is improve performance by formating the
surface to match the display. Of course this is with Pygame 1.9.1.
