Transparency Fill Tool
 

 

The Transparency Fill Tool erases pixels that have roughly or exactly the same color or brightness as the clicked pixel in a flood-fill fashion. The tolerance level is controlled by the level setting and the amount of transparency applied is controlled by the alpha #2 setting in the toolbox. This tool can be used to remove backgrounds, as is being done with the photo of the stranger below. Consider using the Shrink Alpha effect to clean the edges.

 

Options

Normal

This option uses all the color channels to decide what to erase. Pixels that roughly match the pixel under the cursor are erased or partially erased depending on how much they match.

 

Alternate

This option uses all the color channels to decide what to erase just like the normal mode, but using a different algorithm. Pixels that roughly match the pixel under the cursor are erased or partially erased depending on how much they match.

 

Chroma

This option uses the chrominance (color) to decide what to erase. Pixels that roughly match the pixel under the cursor are erased or partially erased depending on how much they match.

 

Luma

This option uses the luminance (brightness) to decide what to erase. Pixels that roughly match the pixel under the cursor are erased or partially erased depending on how much they match.

 

Exact

This option uses all the color channels to decide what to erase. Pixels that roughly match the pixel under the cursor are erased or partially erased depending on how much they match.

 

 

 

 

These are the Tool-box, Palette and Layers windows, respectively. For help on how to use them, consult the User Interface article.
