One or two more issues with the Mask dialog

[davidh]

1. Load an image
2. create a mask using the Mask dialog, do not close it
3. start a transformation, load the mask, click OK
4. dblclick the mask output to recall the mask dialog
5. close the mask dialog with the x button
6. dblclick the transformation output to recall the transformation dialog -> PWP crashes

Another scenario with reset

1. Load an image
2. create a mask using the Mask dialog, click OK
3. start a transformation, load the mask, click OK
4. dblclick the mask output to recall the mask dialog
5. reset the mask from the Mask1 icon command *
6. dblclick the transformation output to recall the transformation dialog -> PWP crashes

* leaving the mask dialog open, closing it with x button or click OK, does not make any difference


Just out of curiosity: loading a mask into Saturation transformation takes visibly longer than into other transformations.

When you use Saturation with a mask, it pre-computes large lookup tables that remap every possible saturation level for every possible mask value.

I'll take a look at the mask issues. A lot of these problems arose when I fixed the mask reset bug earlier.
