Missing SWT Image Constants [message #988899]

Hi,

I am trying to create a grayed (or disabled) version of an SWT image as described in [1] under "Image Effects":

Image grayImage = new Image(display,image,SWT.IMAGE_GRAY);

However, neither the SWT.IMAGE_GRAY nor the SWT.IMAGE_DISABLE constants seem to be available in RAP 1.5.
Any suggestions on how to achieve this in RAP?

I know it is possible somehow because disabling a button that has an associated image does gray out/disable that image.

Thanks,
Franz-Stefan

(I use the SWT class from org.eclipse.rap.rwt-1.5.1.20120917-1116.jar).

Hi Franz-Stefan,

There is an open feature request for this: [1]. However, it's not a
straight forward implementation, because SWT uses native libraries to
transform images, which we can't do in RAP. I guess the simplest
solution is to create and register grayed images on your own.
Alternatively, you can use some third-party library to process images at
runtime.

Disabling a button does not change the actual image in RAP.
