Thank you for the response Peter. Pygame image to string code below def displayscreen(): ## image_filename = str(va.page) + ".jpeg" # va.page is the current page no filename = "zxs" + str(va.page) + ".ada" ## images are saved in runs.py and to use it storeno = 2 image2blit = getfrompy.main(filename, storeno = 2) if image2blit == None: ## no image saved in file so draw the screen with make_screen_text make_screen_text() ## now grab the screen screen = SCREEN.subsurface(0, 0, SCREENW, SCREENH) ## convert to string screenstr = pygame.image.tostring(screen, "RGBA", Falsey) ## nowencode and write to dict in runs.py strA = XOR(screenstr, coder) str1 = base64.b64encode(strA) scrnstore [filename] = str1 image2blit = pygame.image.frombuffer(screenstr, ( SCREENW, SCREENH ), 'RGBA') va.getscr = True return image2blit
this code took too long to convert back and fourth. around 6 seconds. screen = SCREEN.subsurface(0, 0, SCREENW, SCREENH) image2blit = pygame.Surface.convert_alpha(screen) memsave = StringIO() pygame.image.save(image2blit, memsave) memsave.seek(0) pygame.image.load(memsave, iname) <- code crashes here strA = XOR(iname, coder) str1 = base64.b64encode(strA) scrnstore [filename] = str1 the above code crashes at the point marked with the message pygame.error: unsupported image format. What I want to do is to grab the screen surface, convert it to a string format and save to a dictionary. The dictionary will be pickled and saved to a file. I want all my images in this file and NOT AS IMAGE FILES ON DISK. Please help to resolve this.
