Dashpad Sketch Editor

Ready.
How to use: Use the Canvas menu to set the actual image size, save/load editable DashpadSketch files, and export a PNG, or copy/open the canvas image from the clipboard command. Use Selected Object to change Z layering or delete the current object. Freehand pen: drag to draw. Click-point line: left-click points, right-click to finish. Bézier curve: click a start point, then click an end point; drag the two control handles afterwards. Select/move: click an object, then drag its points or drag the line/body to move the whole object. Delete line segment: click a segment between two points. Press Delete to remove the selected object, or Escape to cancel the current drawing action.
Canvas size
The PNG export uses this exact canvas size. If “Scale existing drawing” is off, existing objects keep their current coordinates and may be clipped if the canvas becomes smaller.
