Pleased to announce WRP version 4.6! After almost two years of no updates due to dependency issues I finally resolved everything. More frequent work should resume now.

The main improvement visible to users is the new GIF encoding. I have been struggling with poor GIF performance for quite a while. This was mostly manifested on lower end machines running WRP such as Raspberry PI or these micro instances in the cloud.

Thanks to invaluable work of Hill Ma we now have blazing fast GIFs. Probably order of 100x improvements! This comes at a cost of quality, especially of color palette and dithering. However worse quality of imagery has a surprise improvement of font/text quality which is what a lot of people wanted.

Note that by default WRP uses GIF with 216 “web safe” colors. We choose this not so much for number of colors but rather activation of the super fast GIF encoding.

When switching to 256 color mode the image look much better, however it takes around 25x longer to encode (7ms vs 170ms).

When using PNG this is of course not a problem.

0 height mode, which renders tall images of full page length has also been improved and is now more stable. Be careful when using very old machines with little memory as the images can be pretty big.

I hope that WRP will help you use your vintage computers more
