_PALETTECOLOR - mkilgore/QB64pe GitHub Wiki
The _PALETTECOLOR statement sets the color value of a palette entry of an image using 256 color modes or less (4 or 8 BPP).
- _PALETTECOLOR attribute%, newColor&[,]
- The attribute% is the palette index number of the color to set, ranging from 0 to 15 (4 bit) or 0 to 255 (8 bit) color modes.
- The LONG newColor& is the new color value to set using _RGB32 or _RGBA32 values or using HEX$ 32 Bit Values.
- If destHandle& is omitted, destination is assumed to be the current write page or screen surface.
- If attribute% is outside of image or screen mode attribute range (0 to 15 or 0 to 255), an illegal function call error will occur.
- If destHandle& does not use a palette, an illegal function call error occurs. Will not work in 24/32 bit color palette modes.
- If destHandle& is an invalid handle value, an invalid handle error occurs.
