Installed & registered fine for me (I used their button to copy the code from the clipboard). Only difference from version 6 which I had before is addition of a “Detailed Sketch” mode in the Style menu. If Style menu says “Realistic” you get choices of Realistic, Detailed Sketch, and Classic. If Style menu says “Classic” you only get Realistic and Classic in the menu. This in-attention to detail is apparent in other places as well…
I used the option to rotate a picture before converting it to a sketch, and it seemed to mess up the program: the small preview window was rotated to some different angle altogether, and sketches only worked on part of the picture, cutting out the rest, even after undoing the rotate. Seemed like Rotate mixed up the width and height somehow.
Anyway, if you don’t use rotate, this seems to still do a very nice job of making different types of sketches. No, it’s not instant, but what it does takes an enormous amount of calculation. Takes 5-30 seconds depending on pic & style, not a long time to wait. Still my favorite sketch program on PC.
