Adding JPEG 50kb - Output PNG 500kb

Nov 10, 2010 11:05 AM



the following problem was already discussed in the following thread and we didn't find any solution.


The problem is:


I'm adding to my project JPEG image for example 600x400 50kb - after exporting it to SWF by using "export images as separate file" Rome converts this file to PNG and the file size is exploding to 500kb ...

It's equal if I'm using layer stack, clipping frame or if I export all in one SWF file, the size is always the same.


Please for solution!

    Our development team has provided me with the following answer: PNG is a lossless compression format whereas JPEG uses a lossy compression algorithm.


    Thanks again for your feedback,

    Yeah, come on, it's evidently a bug! Nobody is gonna make slideshows with pictures without transparency in PNG format - this format was just not made for it. If I'm importing JPG then exporting it as PNG won't make the quality better.


    From what I've seen ROME already has possibility to export JPG images through Output->Output Channels->File Export->JPG (but only as seperate composition elements, not as a part of a whole project)
