Type Function Return value none Revision Release 2024.3703 Keywords MemoryBitmap, setPixel See also MemoryBitmap MemoryBitmap:getPixel() memoryBitmap.newTexture() memoryBitmap.*
Sets a bitmap pixel to a specific color.
bitmap:setPixel( x, y, r, g, b, a ) bitmap:setPixel( x, y, color )
Numbers. The x and y pixel coordinates to be changed.
Numbers. The red, green, blue and alpha components to set the bitmap pixel to. Values should be in the range of 0 to 1. Depending on the bitmap format, some components may be ignored — for example, a format of "rgb" uses only r, g and b, while a format of "mask" ignores everything but r.
Table. As an alternative to passing r, g, b, and a component values, you may pass color components in a Lua array as noted in the example below.
nil instead of a component value will keep that component unchanged.texture:setPixel( 10, 10, 1, 0, 0, 1 )
texture:setPixel( 10, 10, {1,0,0,1} )
