caca_bitmap * | caca_create_bitmap (unsigned int bpp, unsigned int w, unsigned int h, unsigned int pitch, unsigned int rmask, unsigned int gmask, unsigned int bmask, unsigned int amask) |
Create an internal bitmap object. | |
void | caca_set_bitmap_palette (struct caca_bitmap *bitmap, unsigned int red[], unsigned int green[], unsigned int blue[], unsigned int alpha[]) |
Set the palette of an 8bpp bitmap object. | |
void | caca_draw_bitmap (int x1, int y1, int x2, int y2, struct caca_bitmap const *bitmap, void *pixels) |
Draw a bitmap on the screen. | |
void | caca_free_bitmap (struct caca_bitmap *bitmap) |
Free the memory associated with a bitmap. |
|
Create a bitmap structure from its coordinates (depth, width, height and pitch) and pixel mask values. If the depth is 8 bits per pixel, the mask values are ignored and the colour palette should be set using the caca_set_bitmap_palette() function. For depths greater than 8 bits per pixel, a zero alpha mask causes the alpha values to be ignored.
|
|
Draw a bitmap at the given coordinates. The bitmap can be of any size and will be stretched to the text area.
|
|
Free the memory allocated by caca_create_bitmap().
|
|
Set the palette of an 8 bits per pixel bitmap. Values should be between 0 and 4095 (0xfff).
