Detailed Description

Screen class, actually creates 3 (4) screens internally:

  • visual/display (for the user),
  • priority (contains priority information) and
  • control (contains control information). Handles all operations to it and copies parts of visual/display screen to the actual screen, so the user can really see it.

Member Function Documentation

◆ putPixelOnDisplay()

void Sci::GfxScreen::putPixelOnDisplay ( int16  x,
int16  y,
byte  color 
)
inline

This will just change a pixel directly on displayscreen. It is supposed to be only used on upscaled-Hires games where hires content needs to get drawn ONTO the upscaled display screen (like japanese fonts, hires portraits, etc.).

◆ putFontPixel()

void Sci::GfxScreen::putFontPixel ( int16  startingY,
int16  x,
int16  y,
byte  color 
)
inline

This is used to put font pixels onto the screen - we adjust differently, so that we won't do triple pixel lines in any case on upscaled hires. That way the font will not get distorted Sierra SCI didn't do this
