Hello,
I’m trying to do vignette effect with ImageEn but I’m getting a small problem. Ok so I have my image loaded in the control. The vignette is actually a separate PNG file (See Image 1).
I use ImageEnX1.LayersAdd3 PathToPNGFile to add the vignette as a layer over the image. So far everything works ok (See image 2).
The problem arises when I set the transparency of the vignette layer to a value lower than 255. It does not work correctly and a circle shape appears around the image (See image 3).
If I open the image in PhotoShop, add the vignette layer and set its transparency to say 70%, everything looks ok. (See image 4)
So you can see the difference. How can I get rid of that circular shape and make the transparency “smooth”?
Thanks,
Krishley |

| Please post the actual code you are using and if possible the same two PNG, so I can test them. |

Hi,
due the algorithm used to merge transparency with image alpha channel, this artifact cannot be avoided.
Next minor version of ImageEn and IEvolution will use a better alpha blending algorithm that will solve this problem. |
