hxPixels

An hxperimental (cross-target/cross-lib) Pixels abstract, in Haxe 3.1+

Simple interface to access/manipulate pixel values among different targets and libs, having a way to get/set individual pixels (or bytes), and be able to apply them back to the original source (taking care of framework-specific details under the hood).

API

For the supported libs the following methods are implemented (note that all color values are in ARGB format):

• get/setPixel32(): get/set pixel value (with alpha) at x,y
• get/setPixel(): get/set pixel value (without alpha) at x,y
• get/setByte(): get/set byte value at i
• clone(): make a duplicate of the Pixels instance
• fillRect(): fill a rect area with pixel value (with alpha)
• bytes: access to the raw underlying bytes (in source-specific format)
• format: change internal color mapping

Supported classes/libs

• BitmapData: flash, openfl and nme (and applyToBitmapData() for flambe+flash)
• Texture: for flambe (applyToFlambeTexture() only for html, due to limitations imposed by Stage3d)
• BufferedImage: for java
• ImageData: for plain js
• Texture and AssetImage: for snow/luxe

Implementation

Pixels is an abstract over haxe.io.Bytes. It stores the raw bytes in the underlying bytes var (in source-specific color format), auto-converting to ARGB when using get/set methods (see other branches for the inverse approach).

Usage

See the src folder for examples on how to use it, and file issues if you have problems or spot a bug.
