Hard to use, not sure what the settings do
Response from developer
Thanks for the comment. The landscape format is for the button layout, but I might try to create a portrait layout later. The interface bars change parameters within builtin-apple filters for photo manipulation, but honestly, I have no idea what they do (the documentation is not very detailed). So that is one reason why there are no labels. Getting a clear outline is very hard in general, which is why apple does not provide an outline filter. What is probably happening is that there are small variations in yellow in your picture and the filters treats them as different colors. So one thing to try it is to change your photo in another program so that there are fewer colors or reduce the overall resolution. Finally, it is possible to change the paint color to white and paint over the speckles before saving. There are certain kinds of images that tend to work well with the program and finding them is not so easy. Good luck!
