Hi, everyone.
I'm using work with Magick++.
When I convert PNG(alpha) format image to JPG format, the result image have rectangle blocks of black color along borderline of a picture.
I think it's rectangle block take effect by alpha channel value of png.
How to remove rectangle block of black color?
for more infomation, I want to show you a result image, but I don't know that how to upload a file.
sorry, and thanks.
