[pygame] Inverting colors
Hi, I'm working on a game, and I made a bitmap font for it. This was quite silly of me; I made each letter a 16x16 image. Well, now I need the letters to invert colors. I was wondering if there's a way to do this in pygame, or if I have to go through all those images (around 40) and make a shapestrip or something? Thanks, -- - pymike (http://pymike.4rensics.org/)
Re: [pygame] Inverting colors
The new Color class may have invert but I don't recall. Well the rgb inverted algorithm is essentially 255 - color new_red = 255 - old_red new_green = 255 - old_green new_blue = 255 - old_blue So a subtractive blend mode blit may do the trick: BLEND_RGBA_SUB BLEND_RGB_SUB inverted.fill((255,255,255)) inverted.blit(letters, (0,0), None, BLEND_RGB_SUB) This might work, haven't tested it though...

Re: [pygame] pygame.org - update finished!
http://www.pygame.org/docs/ doesn't have links to the modules Color and Scrap and the alphabetical order is incorrect in some places. Ian

Thanks :-) I actually already converted my font to a shapestrip, and I got it working fine now :-) http://pymike.4rensics.org/files/Screenshot-PixelWars-1.png However pygame SHOULD have a function to invert colors on images. like image.invert() Cheers On Wed, Sep 17, 2008 at 9:26 AM, Nicholas Dudfield [EMAIL PROTECTED]wrote: The new Color class may have invert but I don't recall.

Re: [pygame] Inverting colors
1.9? Until then def inverted(img): inv = pygame.Surface(img.get_rect().size, pygame.SRCALPHA) inv.fill((255,255,255,255)) inv.blit(img, (0,0), None, BLEND_RGB_SUB) return inv pymike wrote: Thanks :-) I actually already converted my font to a shapestrip, and I got it working fine now :-) http://pymike.4rensics.org/files/Screenshot-PixelWars-1.png However pygame SHOULD have a function to invert colors on images. like image.invert() Cheers

Re: [pygame] Good code for text wrapping?
Hmm, I've written this too. Given that it seems pretty common, wouldn't this be a good candidate for adding to pygame.font.Font? -FM On 9/16/08, Marius Gedminas [EMAIL PROTECTED] wrote: On Tue, Sep 16, 2008 at 12:11:45PM +1000, René Dudfield wrote: The cookbook has this entry, but it doesn't work with new lines. http://www.pygame.org/wiki/TextWrapping Anyone have any code like this that supports new lines? http://mg.pov.lt/pyspacewar/trac/browser/trunk/src/pyspacewar/ui.py#L466 Output example: http://mg.pov.lt/pyspacewar/pyspacewar-help-screen.png It's GPL-ed, feel free to use or ask me for a licence change if that's not suitable.

Re: [pygame] Good code for text wrapping?
I'd appreciate it.
Re: [pygame] Good code for text wrapping?
Yeah pygame.font needs support for \n. :P On Wed, Sep 17, 2008 at 2:31 PM, Charlie Nolan [EMAIL PROTECTED]wrote: Hmm, I've written this too.
