JSFormer

Web-based replacement for the MSP432 Image Reformer

Why?

To put it simply, the TI Image Reformer tool is not very good. Here's what I don't like about it:

The image importing is extremely finicky. For example, RGB-mode PNG files are not supported at all even though they display correctly in the preview.
The image conversion is extremely limited and sometimes doesn't even work properly. I've found that it ignores certain colors for no apparent reason.
The exported image data has to be written to a file. Most of the time, you want to include it in an already existing file, so you have to open the exported file and copy/paste the contents.
Judging by the screenshots in the guidebook, the tool is decades old at least and doesn't appear to have been updated much.

This project aims to fix those shortcomings, and add a few benefits of its own:

Better image upload support: An HTML5 canvas is used to render the image, so any image that your browser can display is supported.
Dithering support: JSFormer supports several types of dithering to improve image quality in some cases.
Code export through the clipboard: Now you have several options once you get the code. You can paste directly into an existing file or create a new file and paste in the data.
Code export customization: It is now possible to customize both the image naming prefix used in generated variable names and the indentation style used in the generated code.

There are still a few things that need to be implemented that Image Reformer supports:

RLE compression: I haven't yet dug into the compression format used in GrLib.
2bpp image support: Since the display driver I use on my board does not support 2bpp graphics I haven't implemented this yet. If there is demand I'll implement it (PRs accepted too!)
