New Image Tool!

Though I originally only planned for 3 image tools, the core common tools have come in handy for developing even more tools. My recent release, Colorize Tool for Ren'Py, also uses the same framework. It's a colorize tool which allows for greater control over in-engine recolours of images, matching hand-coloured images more closely than ever before.

I added a couple more common functions and styles that are used in Colorize Tool, as well as links to that tool, if it exists, on the main tool hub page.

If you won't be using Colorize Tool for Ren'Py, you don't need to update. The newest image_tool_common.rpy file is also included in Colorize Tool for Ren'Py's zip to reduce the number of listings I have to send someone around to picking up tools ('cause it uses quite a few), so if you've already picked it up from there, you don't need to download it here also unless there's a later update.

(Also if this is about the 4th devlog you've seen from me in a row, thanks for your patience reading through all of them haha, I updated a lot of tools for this newest one 😅)
