Understanding Tolerance
• The tolerance bar appears throughout many Paint.Net tasks, such as Fill, Transparency and Erase
• The amount of tolerance you set, the more aggressive the tool will be. Tolerance set to zero is the least aggressive.
Understanding Brush Width

• The width of the brush will determine how big an area will be affected.

tool if fill is too aggressive

the background with the wand – then click Delete on your keyboard …..

Cropping images or text art
• Use the Select on the Tools bar to highlight area you want to crop

area remains.• Use clone
stamp to fillin color
Working Cloning Tool
• This tool is useful for copying regions of pixels (colors) between layers, or within the same layer.
• Select Clone Stamp Tool • Find the area you want to “clone” and
CTRL+CLICK on the area• Now change the brush width and fill in
the cloned color where you want it to go
Cloning con’t
• CTRL+ to make image larger• In this example, we need to get rid of
the unwanted sleeve and hand• By cloning the ladies jacket
we can color out the unwanted image.
Using Color Picker

want to use• Use Paint Brush or
Fill Tool to color yourimage
• Different than Clonetool.
Working with Layers

• Add layer• Delete layer • Merge layers• Move up• Move down
Creating Layers
• Add to a layer to an existing image• Or use the Layer Menu to insert
images into a new palette:
Using Transparency & Opacity
• Layers | Import from File
• Use transparency tool on apple
• Use layer Properties to adjust opacity
Results
Manipulating files to add as layers
• If you have different graphics you want to manipulate in layers, size each of them individually in their own files.
• Cropping or changing size of one layer will change all layers when you’re working in one file.
• Importing layers from different files is best.
Example: Using Ellipsis
• Open smiling-girl.jpg file and Save As smiling-girl.gif.
• Use Ellipsis Tool to crop only the smiling girl’s face in a circle.
• Save image and close. • Open camera.png• Insert smilingface.gif as a layer• Center in the lens of the camera• Add Text
End Result
Examples
• Open image in Paint.net
• Use Layers menu to import another image from file
• Remove background from the girl/dog with eraser – adjust pixels of eraser
• Add text in Girl layer
• Merge both pix
Merged layers
•Use Eraser•Increase pixels•Use Rectangle Select bottom•Use Move Pixels button•Added text
