Add 1 pixel of padding between adjacent images in a texture. The
padding should be the same colour as the border colour.
pyglet.resource.image/TextureAtlas don't currently do this because
this kind of image manipulation isn't really supported by pyglet; and
it's easy to pad the images yourself. The following monkey patch will
also automatically add padding, but is only correct if your images
have 0 alpha at the border:
def _texture_atlas_add(self, img):
pad = 1
x, y = self.allocator.alloc(img.width + pad * 2, img.height + pad * 2)
self.texture.blit_into(img, x + pad, y + pad, 0)
region = self.texture.get_region(x + pad, y + pad, img.width, img.height)
return region
pyglet.image.atlas.TextureAtlas.add = _texture_atlas_add
