Using Paint.net

Paint.net screen layout Open images Current image Tools Status line Command menus Tutorials: Community:

Purpose of three of the tools Select a rectangular area Add text to the image Draw a rectangle Experiment — what do each of the others do? (If you do not see the toolbox, give the Windows > Tools command).

Experiment Play around. You can undo any changes you make in the History window. (If you do not see the history window, give the Windows > History command). Ctrl-z undoes the last command. Ctrl-y redoes the last command. ————

The status line: describes the selected tool Tool description with a help hintImage size Cursor location (0, 0 is the upper left hand corner) For example: status line for the Rectangular Selection tool: Tip: watch the status line as you work

These change as you make the selection. You can adjust selections one pixel at a time using the arrow keys. The status line changes as you work Status line while making a selection:

Rotate an image Image > Rotate

View menu Changing the view does not alter the image, just what you see while working on it.

Adjusting contrast Adjustments > Brightness/contrast

Immediate feedback – high contrast

Immediate feedback – low contrast

Apply the ink sketch effect Effects > Artistic > Ink sketch

Resize an image Image > Resize If you check Maintain aspect ratio, changing either the width or height automatically adjusts the other.

Resizing without maintaining the aspect ratio will distort the image

A few questions

How did I do that?

How did I erase the oarlock?
