imageworsener VS ghostedit

Otherwise, compress the images more. https://entropymine.com/imageworsener/ is a versatile multitool with a learning curve. Many image editors have support for downscaling images and compressing JPEGs. pngquant is a PNG-specific tool, if you like PNGs a lot.

There can be various causes for those symptoms:

1. Even if the rendering gets the subpixel order right, the subpixels are rarely equidistant on a display. They tend to be closer to each other within a logical pixel.

2. Some subpixel-AA algorithms are naive, and trade color accuracy to luminance accuracy, causing more color fringes.

3. Incorrect gamma handling.

4. If aiming for more luminance accuracy, incorrectly taking into account the relative luminance of the subpixels (what you observed with the brighter green subpixels).

Imageworsener[1] has an option to downscale with subpixel antialiasing, it's gamma correct by default, and it has an option for adjusting the subpixel offsets within a pixel (instead of the naive default of 1/3). It might be a good way to try out correct subpixel-AA, but it only works on images. I guess you can render text on high resolution and downscale that with imageworsener, but you won't get any hinting that way, but maybe that's desired.

Very few software does AA correctly, let alone subpixel-AA.

I have a 10 year old project on Github. I even have it on my resume. The code is nothing like what I would write today, but I think that's implied by it being 10 years old. And I'm personally quite proud of what I produced, even though I would do it differently now.

Project is a WSYIWYG editor (https://github.com/nicoburns/ghostedit) if anyone is interested. I wouldn't recommend anyone use it these days, but it could be interesting as a relatively small codebase to learn from if anyone is interested in how contenteditable in web browsers works.

Ah, that was a dark time for WYSIWYG editing on the web. I actually made my own back in that era [0] (well a little later, but when TinyMCE and CKEditor were still the goto solutions), and getting it to work cross-browser when IE6 was still a thing and had no dev tools was an absolute nightmare.
