Detailed Description
Video Display Processor tools for modifying display output.
The VDP system allows for a plugin to post-process frames in programs that use RetroFlat. The VDP is provided with a bitmap of every frame in RETROFLAT_STATE::vdp_buffer which it processes and outputs to RETROFLAT_STATE::buffer, which is then displayed on the screen.
Macro Definition Documentation
◆ RETROFLAT_VDP_FLAG_PXLOCK
| #define RETROFLAT_VDP_FLAG_PXLOCK 0x01 |
Flag for RETROFLAT_STATE::vdp_flags indicating the VDP requires RetroFlat to pixel-lock the frame before passing it (almost always true!)
This should be set by the VDP during its initialization.
Typedef Documentation
◆ retroflat_vdp_proc_t
| typedef MERROR_RETVAL(* retroflat_vdp_proc_t) (struct RETROFLAT_STATE *) |
VDP function called from the VDP library.
The VDP plugin should export three functions with this signature:
| Function Name | Called From |
|---|---|
| retroflat_vdp_init() | retroflat_init() |
| retroflat_vdp_flip() | retroflat_draw_release() on screen buffer |
| retroflat_vdp_shutdown | retroflat_shutdown() |
