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.
To do anything you must first have a tool selected. The tool bar is usually on the left side.
If the tool bar shown on the left does not appear or if you lose it:
On the main menu click Window -> Tools.
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.
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.
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.
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.
To save your edited image use File->Save As:
It may be saved as jpg, gif, png or others.
We suggest png.
