TabJpeg

Java front end to cjpeg

This was started because no major grapical app that I used had an easy way to integrate MozJpeg, so I made my own. Yes, this is in Java. If I got Emscripten to work, I swear this would be in JavaScript.

Requirements

• Java 8
• cjpeg binary

run with javaw -jar TabJpeg.jar, or TabJpeg.bat on Windows.

cjpeg must be in the current directory, or in PATH. Compile from source at https://github.com/mozilla/mozjpeg or be lazy and get binaries directly from http://mozjpeg.codelove.de/binaries.html

This uses the Java ImageIO library to do some image processing, so most ubiquitous image formats should be supported (BMP, PNG, JPG). Built with Netbeans.

Features

• Live preview
• JPEG quality control
• Chroma downsampling
• Resizing

Known bugs

• Doesn't load images bigger than about 3 megapixels (1080p screenshots OK)
• Gamma incorrect resizing
