Pilosa - Distributed bitmap index that dramatically accelerates queries across multiple, massive data sets

•    Go

Pilosa is an open source, distributed bitmap index that dramatically accelerates continuous analysis across multiple, massive data sets. Pilosa collapses the speed and batch layer by abstracting the index from data storage, optimizing it for massive scale, and making your data instantly queryable and continuously analyzable.

GlideBitmapPool - Glide Bitmap Pool is a memory management library for reusing the bitmap memory

•    Java

Glide Bitmap Pool is a memory management library for reusing the bitmap memory. As it reuses bitmap memory , so no more GC calling again and again , hence smooth running application. It uses inBitmap while decoding the bitmap on the supported android versions. All the version use-cases has been handled to optimize it better. Glide Bitmap Pool can be included in any Android or Java application.

scientifica - Tall, condensed, bitmap font for geeks.

•    Vim

Scientifica is largely based on creep, with a number of minor tweaks to improve readablity (a matter of taste of course). Most characters are just 4px wide, which is brilliant for low dpi(90-120) displays.

ImageExtensions

•    CSharp

A simple image library for image type detection. Just call IsJpeg, IsBmp, IsPng in a Image or Bitmap class to identify your image.

EWAHBoolArray - A compressed bitmap class in C++.

•    C++

The class EWAHBoolArray is a compressed bitset data structure. It supports several word sizes by a template parameter (16-bit, 32-bit, 64-bit). You should expect the 64-bit word-size to provide better performance, but higher memory usage, while a 32-bit word-size might compress a bit better, at the expense of some performance.The library also provides a basic BoolArray class which can serve as a traditional bitmap.

MagicalCamera - A library to take picture easy, transform your data in different format and save photos in your device

•    Java

You can take photo easy and save too

csharpewah - Compressed bitmaps in C#

•    CSharp

This is a compressed variant of the standard bitarray class. It uses a 64-bit RLE-like compression scheme. It can be used to implement bitmap indexes.The goal of word-aligned compression is not to achieve the best compression, but rather to improve query processing time. Hence, we try to save CPU cycles, maybe at the expense of storage. However, the EWAH scheme we implemented is always more efficient storage-wise than an uncompressed bitarray.

FastBitSet.js - Speed-optimized BitSet implementation for modern browsers and JavaScript engines

Speed-optimized BitSet implementation for modern browsers and JavaScript engines

load-bmfont - loads a BMFont file in Node and the browser

•    Javascript

Loads an AngelCode BMFont file from XHR (in browser) and fs (in Node), returning a JSON representation.See text-modules for related modules.

msdf-bmfont - Generate BMFont texture and spec using msdfgen

•    Javascript

Converts a .ttf font file into multichannel signed distance fields, then outputs packed spritesheets and a json representation of an AngelCode BMfont.Signed distance fields are a method of reproducing vector shapes from a texture representation, popularized in this paper by Valve. This tool uses Chlumsky/msdfgen to generate multichannel signed distance fields to preserve corners. The distance fields are created from vector fonts, then rendered into texture pages. A BMFont object is provided for character layout.

three-bmfont-text - renders BMFont files in ThreeJS with word-wrapping

•    Javascript

Bitmap font rendering for ThreeJS, batching glyphs into a single BufferGeometry. Supports word-wrapping, letter spacing, kerning, signed distance fields with standard derivatives, multi-channel signed distance fields, multi-texture fonts, and more. About 12kb after minification.Works on Three r69-73, r79, and possibly more.

bit-array - JavaScript implementation of bit arrays.

•    Javascript

Even though bit arrays are not that useful in JavaScript, there is one place where they excel; encoding large boolean sets for transfer between the browser and server. A JSON representation of a bit array is much smaller than an actual boolean array. Alternatively you could just include bit-array.js in your project.
