I was trying to create a workaround for redrawing bitmaps without redrawing the whole screen, like layers of bitmaps, but came across a shortcoming of iziBasic.

When copying and setting 16-bit color pixels with PGET and PSET the color is distorted. Only in 8-bit color was I able to copy portions of the screen (sections of pixels) without distortion.

 Hello Roman,

Yes, you might be right about 16-bit color pixels. My guess is that the value that can be stored in a number variable (which is a single real value) is not precise enough to store the real color... I put this one in my to do list for the next version.

Cheers,
aldweb
