Problem setting background color for wave image operation

[SkipperMcNally]

I have trying to apply a wave operation on an image and have the added areas be transparent and having no luck. Any suggestions?

Here is the code:

Code: Select all

$testImagick = new Imagick("input.jpg");
$testImagick->setImageFormat("png");
$testImagick->setBackgroundColor(new ImagickPixel("transparent"));
$testImagick->waveImage(20, $testImagick->getImageWidth() * 2);

The added area is always white, even when I try blank and Red as colors.

Thanks for any help.

Nevermind, I found this old bug report thread that told me I should be using setImageBackgroundColor() instead.

Working code:

Code: Select all

$testImagick = new Imagick("input.jpg");
$testImagick->setImageFormat("png");
$testImagick->setImageBackgroundColor(new ImagickPixel("transparent"));
$testImagick->waveImage(20, $testImagick->getImageWidth() * 2);
