* graphics_utils: check for valid framebuffer before creating a screenSascha Hauer2015-11-131-0/+4
| | | | | | Otherwise we crash later when we try to print on that screen. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* gui: implement blitting screen areasSascha Hauer2015-08-201-0/+19
| | | | | | | So far we only supported blitting the whole screen from the shadow fb to the framebuffer. Add a function to blit areas. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* gui: Use fb provided shadowfb for offscreen renderingSascha Hauer2015-08-201-17/+7
| | | | | | | The fb core now has builtin support for offscreen rendering, use this and drop offscreen handling in the gui code. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* graphics_utils: Let fb_open allocate the screenSascha Hauer2015-07-203-35/+61
| | | | | | | | | 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>
* graphics_utils: add function to create pixel from rgb tripletSascha Hauer2015-07-161-6/+26

* graphics_utils: Export get_pixelSascha Hauer2015-07-161-2/+12
| | | | | | | | | | | get_pixel converts a 32bit trgb color into framebuffer format. This is useful for other code aswell, so export it. Other functions in the graphics utils code use the name get/set_pixel aswell, but instead of converting data they get a pixel from the framebuffer or set a pixel on the framebuffer. To separate from these rename the function to gu_hex_to_pixel. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* graphic_utils: Add a common namespace to functionsSascha Hauer2015-07-153-14/+14

| * image_renderer: Use read_file_2Sascha Hauer2015-06-261-4/+4
| | | | | | | | | | | | | | This returns a proper error code and allows us to print a proper error message which might not always be -ENOMEM. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | bmp support: Use unaligned accessorsSascha Hauer2015-06-231-5/+6
|/ | | | | | | Some fields in the bmp header are unaligned. Use unaligned accessor functions to acces them. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* move file helper functions to separate fileSascha Hauer2014-08-071-0/+1
| | | | | | | | | | We have our file helper functions in several places. Move them all to lib/libfile.c. With this we no longer have file helpers in fs/fs.c which contains the core fs functions and no functions in lib/libbb.c which are not from busybox.

* gui: IMAGE_RENDERER does not depend on VIDEOSascha Hauer2014-06-051-1/+0
| | | | | | | | | Image renderer may not be particularly useful without framebuffer support, but technically it does not depend on VIDEO. Fixes: warning: (CMD_SPLASH) selects IMAGE_RENDERER which has unmet direct dependencies (VIDEO) Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* | filetype: Pass bufsizeSascha Hauer2012-12-031-3/+3
|/ | | | | | | | | | Pass the buffer size to the file detection code. This makes sure we do not read past the buffer. This is especially useful for ext filesystem detection as the magic is at byte offset 1080. Also introduce a FILE_TYPE_SAFE_BUFSIZE define which is set to the minimum bufsize the detection code needs to detect all known filetypes. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
