Black background spritesheets

[eguneys]

I have spritesheets with a black background, is there a phaser way to extract the images transparently, or do i have to manually convert black to transparent.

You can use http://docs.phaser.io/Phaser.BitmapData.html#replaceRGB, I think

You should really supply the images as already transparent rather than processing them each time your game loads. Also depending on how the art is created, replacing black may not have the effect you desire (i.e. you may end up with bits replaced that shouldn't be, and black fringes on the edges of sprites)
