:What is unclear to me is, can we use the existing bitmap image services of the language, or should we implement it from scratch using e.g. arrays? In RapidQ, I used QCanvas object. It has built-in methods for filling image, for drawing pixel and for reading pixel color, so there is no need to define any procedures. Many BASIC versions write directly to display hardware (e.g. in DOS or when using OpenGL or DirectX). Can this be used or should we have an off-screen image storage? --[[User:PauliKL|PauliKL]] 16:31, 20 February 2009 (UTC)
::I would say it is OK to use device contexts, hardware buffers etc. So long you can implement the task from this [[:Raster graphics operations|category]]. However it could become quite tricky when it comes to digital filtration and other image processing techniques, because drawing contexts are usually oriented only to rendering. --[[User:Dmitry-kazakov|Dmitry-kazakov]] 20:24, 20 February 2009 (UTC)
