Edit bitonal images at the pixel level using resizable brushes and automated line-drawing functions.
Touchup tools are provided on the Touchup toolbar.
The touchup brush can be square, round, or diagonal rectangular in shape. You can resize it to match the line weight in your drawing. The brush size remains constant in relation to the pixels, so it varies with your zoom level.
Using a toggle control, you can switch from foreground to background color, in effect switching from drawing pixels to erasing them.
The Shift key provides two automated line-drawing controls. You can restrict the line direction to horizontal, vertical, or 45-degree angle. You can also create lines or polylines.
AutoCAD Raster Design toolset uses Single Image Optimization to speed up the editing commands.
