Image editing using Paint.NET

Paint.NET is a free program that can be used for editing bitmaps. It is available on the machines in the SoP computer unit and library. It can be downloaded from the web. See www.getpaint.net/
There is an extensive online manual on the same site.

This document is a quick guide to the common actions that you may wish to accomplish.

Tools

 To do anything you must first have a tool selected. The tool bar is usually on the left side.

Tool block

If the tool bar shown on the left does not appear or if you lose it: On the main menu click Window -> Tools. This will enable the tool bar block

Paste image from screen

SHFT+PrtScn save the current screen display to the clipboard. Edit -> Paste as new image places this into paint for editing and saving.

Crop image

Select the outline tool. Top left. Shown with blue highlight in tool bar on image.

Drag the cursor over the image to outline the required area. 

Select Image from the menu. Crop to Selection.

Resize image

Bitmap images that come from a source such as a camera will have a high definition (large DPI). This is not necessary for images shown on PC displays. The maximum useful resolution for PC display is 72 DPI. Reducing the resolution will make the file much smaller.

Transparent background

When adding an image to a powerpoint slide with a coloured background the image background can be made transparent.
Only gif of png bitmap file types can be set to have transparent backgrounds.

Save As:

 To save your edited image use File->Save As:

It may be saved as jpg, gif, png or others.

We suggest png.
