Getting Started – The Canvas Paint.Net graphics are composed on a canvas Tools Toolbar To resize your canvas

Understanding the Tools Select area for cropping, copy, move, delete Ellipsis Transparency Tool Fill Tool Paintbrush Eraser Color Picker Clone color stamp Insert Text Shapes Additional Toolbars Available – click Window menu More info!

Understanding the Color Palette Use Left Mouse for Primary Color fill Use Right Mouse for Secondary Color Fill

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 Brush width comes into play with many tools, Paint Brush, Eraser, Clone Stamp etc. The width of the brush will determine how big an area will be affected.

Using the Fill Tool CLICK: the Fill Tool button on the Tools bar Select your primary and secondary colors Swap between colors and fill! Use tolerance tool if fill is too aggressive

Creating Text Art CLICK: the Text button on the Tools bar Then choose, font, size and color from the Color toolbar Then type!

Creating Effects for Text Art CLICK: Effects on the tool bar. Explore the various special effects Press CTRL+Z to undo if you don’t like it

Making images Transparent Only.gif and.png files can be transparent. Refer to Reading on TransparencyTransparency Click the Transparency Tool on the Tools bar (Looks like a magic wand!) Start with tolerance is set to zero, then click the background with the wand – then click Delete on your keyboard ….. Adjust tolerance higher if necessary

Making images Transparent Click Magic Wand Click Background Click delete Tolerance determines how aggressive the tool is in deleting. Make small images larger Play with it!

Transparency (con’t) The checkerboard background on your image means that it is now transparent Adjust the tolerance if you are not happy with the result.

Copy images into Paint.Net Create a new canvas. Find the image chapel.jpg, copy it, then go Paint.Net and Paste! If the image is too large, Paint.Net gives you the option of expanding the canvas to fit:

Copying image…con’t Use your PRT SCR Print Screen Command Paste into Paint.net Expand Canvas

Resizing the image Pay attention to the image size: Open chapel.jpg

Cropping images or text art Use the Select on the Tools bar to highlight area you want to crop CLICK: Image Crop to Selection Only the highlighted area remains. Use clone stamp to fill in 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 Click the Color Picker Click the color you want to use Use Paint Brush or Fill Tool to color your image Different than Clone tool.

Working with Layers You may think of "layers" as a stack of slides that, when viewed together, form a complete image 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
