Pictures Side-By-Side / "Before and After" Images
This question comes up in the GD&Q fairly often.


1-

Open the "Before" picture in Paint.NET.

Set Units to Pixels

The pixel dimensions of the image are shown at the bottom right, in the status bar.

Click on the menu item - Image

Click on Canvas Size

===================================

Be sure that there is no checkmark at - Maintain Aspect Ratio

Double the Width number.

Example - 722 X 2 = 1444

Anchor - Left

OK

Import the "After" image.

Layers > Import From File



This will bring the "After" image in as a separate top layer.

The "After" image will automatically be selected, and the Move Selected Pixels tool :MoveTool: will be activated.

Use your mouse to move the "After" image to the right.

To make fine adjustments, use the keyboard Arrow keys.

===================================

Once all images are positioned where you want them,

File > Save As...

Save as whatever file type you want.

This tutorial shows how to place two images equal in size next to each other.

If the images are of different pixel dimensions,
you may want to resize and/or crop the larger image before starting.

Just an observation... If you open the after file first, anchor right in step 2 and then import the before file, step 4 can be removed from the process.

Yes, that is clearly the more efficient way of doing things.

This is targeted for beginners.

I don't want to confuse things by telling them to do
the "After" before the "Before", and the "Before" after the "After".

The tutorial as-is introduces the use of the Move Selected Pixels tool.

Your post is a worthy addition.

Sarkut, how would I go about making 4 different pics 2 on the top and two on the bottom, side-by-side and connected top and bottom?

Also if I needed to put more than two together either horizontally or vertically, or together as I requested above but with more than two, is there a different procedure?

It's the same process - repeated.

The easiest way to explain it it to perform the above side-by-side transformation on both the upper images. Repeat that to connect the two lower images.

Finally use the same technique to expand the canvas depth to allow the combined-upper and combined-lower images to be combined.

Try it.

When you get used to the technique you'll probably figure out that the whole process can be done more simply by expanding the canvas once, and importing the other three images one at a time into separate layers. Then the process is using the move tool :MoveTool: to individually position each layer relative to the others.

How do I expand the canvas? From what you just said, I think I would rather try this way than the beginner way. BTW, I'm able to do this right away. Yesterday I had a family emergency so I wasn't able to get to it until now.

Pressing F1 in Paint.net will take you to the same online docs.

Okay, it took a little while but I figured it out. At first I couldn't figure out how to get the pics underneath the first two side-by-side pics. Then the light-bulb went on.

You have to change the canvas height also.

Ego Eram Reputo, when you said "Finally use the same technique to expand the canvas depth to allow the combined-upper and combined-lower images to be combined." I was a little confused and had no idea exactly what that meant. I now assume when you said canvas depth that you were talking about the canvas height. Thanks for you help.

Canvas height or canvas depth as opposed to canvas width, you got the idea!

Glad I was able to help.

Thanks anyways but I am completely unschooled technologically so I don't even understand the instructions. Way, way too complicated but I appreciate the effort.

What problem are you having? If you don't understand what is written, the picture illustrates what is said. How is this difficult? Plus it's only 5 steps.

Thank you for this.

If I may ask here - I wrote some text in BEFORE picture and then imported the AFTER picture and wrote something in it too.

If I want to modify text in the BEFORE picture later, can I do that and if so - how? For now, it seems to me that I can only edit the picture that I most lately imported.

I use images for mental mapping so I constantly put something on the pictures so I want to be able to put something in my images some time later.

Please excuse my ignorance, answer to my question is trivial.

Text cannot be edited once it is committed to the canvas. This means that once you're finished with the Text tool :TextTool:, the characters become collections of pixels in the layer.

For this reason we advise placing your text on it's own layer. If the text needs to be replaced it is straightforward to delete the layer contents and retype the text in the same color and font.


You may be having another issue, that of changing the active layer, because editing operations are applied to the active layer. To change the active layer, click on the new layer name in the Layers Window - this clicked layer should receive the editing focus and display a highlight in the Layers Window.
