Help with export snapshot

[Mark Schonewille]

Hi Tom,

Whenever you mention you get an error, you should post that error.

You define a rect, but you don't tell LiveCode what the rect belongs to.

Your approach:
put the rect of graphic "PreviewRect" of group "PreviewGroup" of this card into myRect
export snapshot from rect myRect to tPreviewImage as PNG

This should be:
export snapshot from rect myRect of this cd to tPreviewImage as PNG

I'm not sure that you actually need to define this rect separately. Can't you export it directly?

export grc "PreviewRect" of grp "PreviewGroup" of this cd to tPreviewImage as PNG
