Online Histogram Tool Intro
Recently I've been playing with Android's Bitmap processing using NDK (C++) and RenderScript. I used these technologies to create an Image Histogram. I later decided to create a similar tool for web using WebAssembly
www.sisik.eu/histo
The online tool has the following features
- can extract pixel values from various image file formats
- draws histogram using JavaScript canvas (there are some options that can influence how histogram is displayed)
- allows to export histogram values into a
CSV
file, so that the values can be processed in a spreadsheet application
