Description
i. When you set the Preview check button to False, the preview gets black (other filter dialogs show the original image without the filter applied)
ii. The preview is different from the final result.
iii. The final result is not the expected result.
Steps to reproduce i:
- Open an image
- Go to Filters → Distortion → Blinds...
- Uncheck the Preview choice.
Steps to reproduce ii:
- Open an image
- Go to Filters → Distortion → Blinds...
- Set different displacement and number of segments values (for example if you set number of segments to 100, the preview is the same with the original image no matter what you set the displacement value to, but it's not the only case)
Reproduction example for iii:
- Create an image of resolution 400x400
- Fill it with a color (different from white so you can see the blinds)
- Go to Filters → Distortion → Blinds...
- Set the Displacement to 21 and the Number of segments to 67 Press OK and although you set the number of segments to 67 the resulting image will have 2 stripes
