To edit and apply special effects to portions of your pictures, remove unwanted objects, or cut out objects from one picture and put them on another, that portion or object should be selected using a selection tool or a combination of selection tools in Pixelmator.
The most basic selection tools in Pixelmator are the Rectangular Marquee, Elliptical Marquee, Column Marquee and Row Marquee Tools. Rectangular Marquee and Elliptical Marquee Tools in Pixelmator are perfect for making simple, but precise selections – such as regularly elliptically or rectangularly shaped objects. Column Marquee and Raw Marquee Tools are great for selecting columns and rows.
Step 1
Open an image in Pixelmator, preferably one with oval or rectangular objects.

Step 2
Click to select any of the Marquee Tools in the Tools palette.
For smooth selection edges make sure Smooth Edges are selected before making a selection with the Elliptical Marquee Tool. For the jagged, but precise edges deselect Smooth Edges.

Step 3
Drag over an area to make a selection.

Step 4
Once a selection is made, the selection borders can be easily modified if necessary.
To modify the selection borders, choose one of the following selection modes in the Tool Options bar:
![]() |
New | Creates a new selection. |
![]() |
Add To | Adds new selection to an existing selection. |
![]() |
Subtract | Subtracts from an existing selection. |
![]() |
Intersect | Subtracts the overlap of two selections. |
And click and drag to add to, subtract from or intersect with the current selection borders.

The selection borders can be modified using any of the selection tools.
Step 5
After making a selection, any changes can be added to the selected region. For instance, selected area or object can be moved, rotated, scaled, flipped, duplicated, cut, filled, inverted, copied and pasted elsewhere. Also color adjustments and corrections, various special effects and filters can be applied to the selection.

Marquee Selection tools are quick, powerful yet easy-to-use while making simple, but precise selections.
This is a total ‘newbie’ question, but what have you actually achieved in this tutorial. Could you not have a side by side comparison, to clearly show the differences. Scrolling up and down makes it difficult to see the before and after. Apologies, if my question appears dim!
Bill,
The goal of this tutorial is to explain the basics of working with the Marquee tool.
I am part of a start up business that will be staining concrete driveways, patios and poolsides. We are looking for a program that will let us take our 80 color chart and put any of these colors on a driveway patio or poolside.
Is it possible to take a tool, outline the shape of one of these concrete areas and then paste a new color into them?
Thanks,
Jeff
esiste versione in lingua italiana?
No, sfortunatamente no. Tutorials sono solo in inglese. Ma puoi tradurlo con il Google Traduttore
It’s nice…
hi, i just bought the pixelmator. I try to find a german introduction but i only found your site here but it´s´all in english. Can I get a quick tip ? I could not find it on my pixelmator pgm, or is there any introduction as part of the pixelmator app? I bought it and wanted to start at once but it seems that I cannot work before understanding the pgm.
Hi, is it possible to copy/paste the cropped circle onto another photo, and how do you do it?
Hi Sine,
Yes, simply select an area, choose Edit > Copy. Then, switch to the image where you want to paste it and choose Edit > Paste.
