I found Numeric indispensable for shadow effects. import pygame import Numeric pygame.init() screen = pygame.display.set_mode((640,480), pygame.SRCALPHA, 32) screen.fill((0,0,255)) myFont = pygame.font.Font(None, 30)nonTransparent = myFont.render("This text should be fully opaque", 1, (255,255,255))
screen.blit(nonTransparent, (0,0))semiTransparent = myFont.render("This text should be somewhat transparent", 1, (255,255,255))
# Get access to the alpha band of the image. pixels_alpha = pygame.surfarray.pixels_alpha(semiTransparent) # Do a floating point multiply, by alpha 100, on each alpha value.# Then truncate the values (convert to integer) and copy back into the surface.
pixels_alpha[...] = (pixels_alpha * (100 / 255.0)).astype(Numeric.UInt8) # Unlock the surface. del pixels_alpha screen.blit(semiTransparent, (0,100)) pygame.display.flip() Hope it helps. Lenard Lindstrom Mike Lawrence wrote:
Ah, well eventually I'll be overlaying different font layers over top of one another so maybe you're right in that my solution is still unsatisfactory.On 6-Sep-07, at 2:00 PM, Brian Fisher wrote:haha... I assumed you wanted something font letters with alpha - so you had something that could be drawn over something other than a solid color - but I guess you could always grab the background behind where you want the text in a surface, blit the text over the piece of the background you grabbed in the surface, then set alpha on the background surface and blit that, and it would work for the effect you want no matter the background.
