Sketch Drawer is a bit of a throwback to the 90s, when plugins for hand drawn FX were common. Nowadays those plugins probably wouldn’t work – I tried several in current & mid-90s image editors [yeah, I still have a couple of those for some reason] – so the main alternative to Sketch Drawer would be the several similar apps in Google’s Play Store. And Sketch Drawer does do what it’s supposed to, though it might perform better using an Intel CPU – with an AMD CPU I’ve got more cores, but less performance per core, & Sketch Drawer tended to mainly use just one. So with a small, 6 MB jpg it took a while, averaging about 7% in terms of the whole CPU, 70-80% on one core, using about 1 GB of RAM.
The setup file for Sketch Drawer doesn’t contain anything extra – basically it just holds the contents of the program’s folder – and as a 1st step takes you to a page on the SoftOrbits[.]com site to fill in an email address. Once you get the email, & it took a while, it’s simply a link to verify your email address – click the link, fill in name & country, and it’ll display the key. Copy/paste the key & the installation will continue, adding the programs folder, plus desktop & start menu shortcuts. Both 32 & 64-bit versions of the app are included in the program’s folder – those shortcuts will point to the version that matches your copy of Windows, 32-bit or 64-bit. The registry just gets 2 keys, one for uninstall & one for the app, but that 2nd key has a LOT of entries – I recorded 766 total in a 32-bit copy of win7.
