This is the default unit that you would like DrawPad to use for measuring length.

When moving an element, it will automatically snap to other element's edge or middle point. Use the distance field to set how close the moving element is to other to snap

When rotating an object, it will automatically snap to 90, 180, 270, and 360 degree orientations. This option determines how close you must be to one of those values before the element will snap.

This option allows you to display grid lines across the canvas at a set interval.

This is the interval (in default units) between the grid lines.

Snapping will allow you to quickly and precisely place elements by automatically aligning the edges with the grid lines, or any ruler guides you may have placed.

This is how far away an element can be from a guide or grid line before it snaps to it.

This option allows you to display grid lines across the canvas at pixel size interval. Can only be enabled when project was zoomed to minimum of 800%

If you have any touchpad devices attached to this computer, enable this option to use them with DrawPad.

If you want to draw from any and all input devices (mouse, touchpad, etc.), enable this option. If this option is disabled, DrawPad will only collect input from the Current Touchpad Device.

If you only want to collect input from one touchpad device, then select it from this drop-down list. If the device you select is pressure sensitive, you will see the message "This touchpad is pressure sensitive" displayed underneath the drop-down list.
