region position and size check

Asked by jian

Hi, Alex

The topoffset, leftoffset, width and height of a region can be set in region option with a very large number, can be allowed to set far beyond the resolution.
For example, for resolution 1920x1080, I can set the leftoffset to 30000, is there any special need or any special consideration?

Thanks.
Jianjian

Absolutely. It's sometimes desirable to put a region off the visible screen
or overhanging the edge. For example if you have a video and just want to
hear the sound or an image or website that needs to crop

Thanks Alex

If you want to hear sound, you can just set the width, height to 0, 0, and put the video at position(0,0), I tested mp3 as backgound sound before in this way.

If there is a region in very far position, the preview layout may not work properly, and also it's not very easy to find a this kind of region.

Thanks.

If you put a limit someone will come along and want a webpage that
overhangs by more, or will define a custom resolution that exceeds the
limit you set
