Flex colorizer: using ColorTransform class to colorize objects at run-time

Posted by Unknown Senin, 18 Juli 2011 0 komentar

In this post I wanted to show you a nice trick how to colorize visual object at run-time.
Colorizing of the plain object (e.g. rectangle) is very simple:

var colorTransform:ColorTransform = new ColorTransform();
colorTransform.color = color;
target.transform.colorTransform = colorTransform;

But what if you need to colorize some complex object (e.g. image of the rooftop)?

Solution...

1. Prepare color layer (area that you want to colorize) and save it as a separate image

2. Place color layer image over the original image with blendMode="normal"

3. Apply colorization for color layer image:

var colorTransform:ColorTransform = new ColorTransform();

colorTransform.color = color;

target.transform.colorTransform = colorTransform;

Results:
