openmsx::CharacterConverter< Pixel >::CharacterConverter | ( | VDP & | vdp, |
const Pixel * | palFg, | ||
const Pixel * | palBg | ||
) |
Create a new bitmap scanline converter.
vdp | The VDP of which the VRAM will be converted. |
palFg | Pointer to 16-entries array that specifies VDP foreground color index to host pixel mapping. This is kept as a pointer, so any changes to the palette are immediately picked up by convertLine. |
palBg | Pointer to 16-entries array that specifies VDP background color index to host pixel mapping. This is kept as a pointer, so any changes to the palette are immediately picked up by convertLine. |

void openmsx::CharacterConverter< Pixel >::convertLine | ( | Pixel * | linePtr, |
int | line | ||
) |
Convert a line of V9938 VRAM to 512 host pixels.
Call this method in non-planar display modes (Graphic4 and Graphic5).
linePtr | Pointer to array where host pixels will be written to. |
line | Display line number [0..255]. |
