In Pixlr, the Influence Panel is used to create masks. You can then apply effects or modifications to these masks. All of the tools in this set are focused on creating masks.
The influence panel is only available for Pro members.
How do I select a color?
Use (color selection) to grab a color from your screen that's affected by the influence mask.
Use its tolerance slider to either add more or less colors to your selection.
Use brush selection to add to the mask before applying an overlay, such as explode.

How can I make a rectangular or elliptical selection?
Use (marquee) to define rectangular or elliptical selections areas. Use to add to or to subtract from a selection.
Use feather to set the softness of your mask edges, so they blend in better with the rest of the image.

I want the influence of my selection to fade
Use (gradient) to transition the sky to the water, one effect or adjustment into another, or if you want the foreground to be high-contrast and background low-contrast.
Choose the type of gradient mask, linear, radial, or reflected.

I want to add a decal onto the side of a car
Use (object selection) to specify the element you want to add the decal to. Use the blending tools to help it look like part of the original photo. See Blending for more information.
When adding something to the body of a car, such as a decal, try to find an image that has a plain surface. See the following example:
Can I select an object in my image and place it in a different environment?
This isn’t about cutting something from one image and pasting it into another. Here we remove the background of an image and replace it with another.
Define the background of an image with any of the influence masks. Use feather to soften the edges of your mask. Then, use refine > double exp to bring in another image for your background.
New background added
How do I invert a mask?
Sometimes it is easier and faster to select the area you don’t want, then invert your selection.
|How do I duplicate a mask?
Sometimes you want to duplicate a mask, use it again, and just modify it a bit. For example, you’ve made a mask for a house.
You make a duplicate of the mask and remove the door from it, so the door is not affected by the second mask.
Once you create a mask, click to access a menu and select duplicate.

How do I rename a mask?
When editing an image, you may want to use a number of different masks. Use rename to label them for easy identification.
Once you create a mask, click to access a menu and select rename.
How do I delete a mask?
Whenever you want to completely delete, not just clear a mask, use delete.
How did you do that?
To change part of the main image and place it elsewhere, you need to create a bunch of masks, then use blending and double exp.
Making the masks
You will probably need at least 4 masks, one of the main image, another for what you want changed, a background mask, and shadow mask.
These 4 masks will be found in the influence mask.
Changing the seat cover
I wanted to make the seat cover more interesting, so we will use the seat cover mask to achieve this.
Changing the background
Let's put this camel into a different setting. For this, we need the bkgd mask.
Adding a shadow
We don’t want the camel to look like it’s floating in the water, so we will use the shadow mask.
