Screen buffers for graphice.
|
|
|
|
|
|
## `void gfxInitDefault(void);`
|
|
Initialize LCD framebuffers with default parameters:
|
|
gfxInit(GSP_BGR8_OES,GSP_BGR8_OES,false);
|
|
Internally calls `gspInit()`.
|
|
|
|
## `void gfxExit(void);`
|
|
Destroy everything gfx-related.
|
|
|
|
## `void gfxFlushBuffers(void);`
|
|
Draw the buffer.
|
|
|
|
## `void gfxSwapBuffers(void);`
|
|
??? idk call it after gfxFlushBuffer().
|
|
|
|
## `enum gfxScreen_t;`
|
|
Represents each screen.
|
|
- GFX_TOP: Top screen.
|
|
- GFX_BOTTOM: Bottom screen.
|
|
## `enum gfx3dSide_t;`
|
|
Represent each image for the 3D screen.
|
|
GFX_LEFT: Left eye.
|
|
GFX_RIGHT: Right eye.
|
|
|
|
## `void gfxSet3D(bool enable);`
|
|
Enable or disable 3D on the top screen.
|
|
|
|
## `bool gfxIs3D(void);`
|
|
Check whether the 3D is enabled on the top screen.
|
|
|
|
## `u8* gfxGetFramebuffer(gfxScreen_t screen, gfx3dSide_t side, u16* width, u16* height);`
|
|
Get all the data which will be display to be able to modify it.
|
|
If `gspInit()` was used, the return data is formatted as follow:
|
|
- Each byte is a color value.
|
|
- The colors are in order: blue, green, red. 3 bytes make a pixel.
|
|
- The pixels are from the bottom to the top of the screen. 'width' pixels make a pixel column.
|
|
- 'height' colums make the screen.
|
|
The size of the returned value is: 3 (colors) * width (rows) * height (colums).
|
|
Arguments:
|
|
- screen: screen to get the frame buffer from (either GFX_TOP or GFX_BOTTOM).
|
|
- side: for the 3D screen GFX_LEFT for the left eye image, GFX_RIGHT for the right. If bottom screen or if not 3D, use GFX_LEFT.
|
|
- width: height of the screen (yep)
|
|
- height: width of the screen (yep yep yep doesn't make any sense)
|

# TO SEE:

|

## `bool gspPresentBuffer(???);`
|
