问题
I have a transparent PNG Image. I want to add it as watermark for this video recording software. But the problem is, software requires jpeg image as a watermark. When I converted that image to JPEG(using Pixle Editor) it lost its transparency and does no look good in video.
How do I convert Tranparent PNG to Tranparent JPEG?
It doesnt matter how or which tool.
EDIT:
How to convert transparent PNG to transparent GIF?
回答1:
JPEG format does not allow transparency. It does not include an alpha channel. So the answer is : there is no such thing as a transparent JPEG image. Transparency is possible using PNG, GIF or vector based formats, dunno if you can manage the watermark in those?
