Select Transparency Color

With reaConverter you can customize the transparency color that appears in your input image file when preparing for conversion.

When you want to edit and convert images that contain transparent layers, being able to clearly distinguish these layers from the rest of the image can be very helpful. Because transparency is normally rendered as white, making the difference between the transparent sections of the image and the ones which are actually white might be difficult.
