Re: How to cut out shapes precisely
If the enclosing square is a solid white color - or any other color without variation, like a real photo background, it's pretty easy. Click the Image tab in HyperSnap 8, then "Substitute" button. Add a color replacement, and make the "old color" there white. Make sure it's the same white as on your bird background, best click the "Pick" tool next to "Old color" label, then click on this white background on your image. The "New color" does not matter, you may leave it white. Then also click to put check-mark into the "Set opacity of the new colors" box, and type 0 in the edit text box next to it. This will make the white color completely transparent. Click "Apply" and look at the result, if you accept it, click "Done". Now save your image as PNG file, with transparency. You may copy this bird image, then paste on another image (e.g. a photo) in HyperSnap 8, should work as you expect.
