(Canvas) A technical drawing, image editing and page layout program for Windows and the Mac from ACD Systems International, Inc., Victoria, British Columbia (www.acdsystems.com). Acquired from Deneba Software in 2003, ACD's Canvas combines numerous illustration (vector graphics) and image editing tools (bitmapped graphics) in one application. It also includes presentation graphics capabilities for producing on-screen slide shows. Specific versions have been created for GIS mapping, scientific imaging and the professional design engineering market.
Canvas combines extensive drawing and imaging tools in one program. The PC drawing on top is a vector graphics rendering and the "first mouse" below is a bitmap. The open menus show image editing tools that are not normally found in a vector graphics drawing program.
