Influence panel


The influence panel is only available for Pro members. 

Don’t let the size of this panel fool you. It houses some of the coolest and most useful tools in Autodesk Pixlr. With these tools, you create influence masks for isolating specific areas to then apply changes to only those areas. The masks are saved, so future change can be applied to those same areas of influence.


Since there are a number of tools to choose from, figure out what you want to select first to help determine which tool is best suited to the task. If color selection is what you want, use . If you want to distinguish a foreground element from everything else, use.

Clicking  accesses tools for inverting, duplicating, renaming, and deleting a mask.

What exactly is an influence mask? 

An influence mask is a defined region that can be edited without affecting the rest of the image. It is created with a selection tool. Once created, anything you apply to the image only affects the area within the influence mask.

NOTE When using any of the fast tools, keep in mind that they affect the entire image, regardless of whether you have an Influence masks or not.

How do I create an influence mask?

Once you’ve determined the area you want to change, you’re ready to create your influence mask.

In the influence panel, click any of the selection tools to define the area of influence and create influence masks.

What are the selection tools?

The selection tools help you select areas of your image to create influence masks. Once you have painted over or tapped an area, you can either add to or remove things from the mask. Use the tools within the selection tool to add and remove, along with other settings.

The following 5 selection tools are found in the influence panel: 

Color selection - Click the color you want influenced by the mask. To adjust your selection by adding or removing color from your selection, change tolerance, which will increase or decrease the range of color selected.
