* graphics_utils: Let fb_open allocate the screenSascha Hauer2015-07-201-1/+1
| | | | | | | | | Allocate the screen dynamically in fb_open. This opens the way to create a fb_create_screen function which takes a struct fb_info * instead of a filename. This is suitable for the framebuffer console which already has a struct fb_info *. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* gui: Fix typo in function nameSascha Hauer2015-07-151-1/+1

* gui: blit the surface on demandJean-Christophe PLAGNIOL-VILLARD2012-10-041-3/+0
| | | | | | | | Do not blit the surface everytime we write an image As we want to able to render multiple image this will cause 1 blit per image; Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* gui: introduce screen and surface to factorize and simplify codeJean-Christophe PLAGNIOL-VILLARD2012-10-041-15/+19
| | | | | | | | | | Instead of passing hundreds of parameter, just pass the right structure. struct screen represent the screen with a without double buffering. struct surface represent the part of the screen we want to render.
