GrafX2 vs DragonBones Pro

GrafX2 is scriptable using the Lua language, which can be used to automate tasks and add new functionality to it. The script library features advanced color reduction and enhancement tools, palette analysis, and much more.

GrafX2 supports many file formats, including the popular gif and png, but also importing and exporting from deluxe paint, degas elite, and various other editors using custom formats.

GrafX2 is totally free to use, copy, and modify. It's available on Windows, Linux, Mac OS X, Haiku, AROS, MorphOS, SkyOS, Syllable, Mint, and a few more systems. Basically anything is supported by the SDL library.

GraphX2 being based on older 256 bitmap software has inherited some tricks that modern pixel editors do not have . One of them being the ability to cycle color palette and produce animations and effects with it.

You can create gradients from one color to another, work in either RGB or HSL color space, save and load palettes, sort and organize palettes, and even work on "color cycling" images.

The program has a basic support for animation using frames in newer versions. Graphics can be cloned and copied between frames and changed slightly.

Theme UI style can easily be changed from settings including buttons and colors.

The program is able to enforce the pixel constraints of old machines (C64, ZX Spectrum, Apple II, Game Boy Color, etc.)
For example, in ZX Spectrum mode, only 2 different colors can be used in a 8x8 pixel block.

This is a very useful feature because you can make a walk animation that you can simply change the animation weight to see the character start running, because it will increase the scale of the movement of the bones in the animation. This will increase the hand and the leg swing as you increase the animation weight and the character, making it appear as though it is running.

Can easily switch sprites in between the animations like switching clothes and other multiple behaviors.

Watching and moving can be programed depending upon certain events.

Size as well as animation speed can be easily changed during an animation.

Can easily export to different texture sizes to target multiple resolution platforms.

Can easily change the Z-Order of a sprite during an animation and can also change the color mask on a sprite, in between an animation.

Create once and use the same animation for different characters just by simply cloning the same animation for the new characters.

You can nest skeletons and change the timeline of the animation in between the animations in order to make some cool effects.

There is an extension available for Adobe Flash users, which gives a WYSWYG design window inside of flash.
