FAQ: Why are some details missing for images with transparency?
Identify if the output is missing important details because of an input image with multiple transparency values.
Open the tab 'Transparency' tab and enable Replace transparency with solid color to yes. If a different background color is more adequate for your image you can select it using the color dialog.
Here in this example we also switch to "Sketch" because the input image is only greyscale and has no colors.
All the important details are now visible in the output.
Step 5: (optional)
It is possible to use the "Remove Background" feature to make the background transparent again if required.
