Loading masks and alpha channels

You can modify the current mask in an image by loading a mask saved to an alpha channel.

When you load a mask saved to an alpha channel in the image, you can choose the mask mode that is used to apply the mask. Depending on the mask mode you choose, the saved mask either replaces the current mask or is combined with it.

You can also load a mask or a color mask from disk and replace the current mask. You can apply the mask over a specific image area or over the entire image.

When you load an alpha channel from disk, you can apply the mask saved in the alpha channel to the current image.
