set CGContextSetAllowsFontSubpixelQuantization to False #541

Open typemytype opened 1 year ago

during animation with text and textBox minimal changes in the formattedString (pointSize, variable settings, ...) influences the pixel output heavily

setting Quartz.CGContextSetAllowsFontSubpixelQuantization(context, False) disables subpixel rendering, see

proposal:

add saveImage argument: subpixelRendering=False the default would be True so nothing changes

Great find! No longer we have to render text as BezierPaths to avoid this effect!
