There are three main steps to mirror text and images using Paint.net. 1. Type your text and/or choose your image. 2. Duplicate the layer & vertical flip it. 3. Gradient the text/image using transparency.
I'm going to tell you each step and use a few screen shots, but I also did a video tutorial. If you want to skip this written tutorial, you can find the video tutorial at the end of this blog post.
Here's the text tutorial: How to mirror text and images using Paint.net:
Select New and key in the width and height you want your mirrored image to be.
Add a new layer. Click on the Text icon and choose your preferred font and text size. Type in your text and if you're including an image, then open/select, copy and paste/position in your image.
Click on the duplicate layer icon in the Layers dialog box to duplicate the layer. Click on Layers in the menu and select Flip vertical to flip the duplicate layer.
On your keyboard, hold down the Ctrl key and click the up arrow button to gradually move the flipped layer closer to the upright one.
When you've positioned the flipped layer in the desired position, click Edit in the menu and click Deselect.
Merge all layers together by clicking the Merge layer down icon in the Layers dialog box. Click on Gradient icon in the Tools dialog box. In the Colors dialog box, change the primary color to transparent and the secondary color to white. On the gradient tool options choose Color and Normal blending.
Somewhere on the upright text/image, Click and hold down the mouse and drag it down into the flipped text/image. The top will be transparent and the bottom will be blended white.
Adjust as needed, by clicking, holding down and dragging the tiny circles. There's your mirrored text/image. Crop it and/or adjust as needed.
I hope this short Paint.net tutorial helps. Remember, the video tutorial is below. Thank you for reading and watching.
