Re: Import or export snapshot at current scaleFactor

Thanks Jim, that’s perfect! I don’t know how many times I’ve looked at the 
import/export command in the dictionary and not seen the size modifier.

Much appreciated.

Terry,

Try this

import snapshot from ObjRef at size (the width of ObjRef * 
scaleBy),(the height of ObjRef * scaleBy)

Where ObjRef is the object whose snapshot you want to import and scaleBy is 
the scaling factor. So something like:

import snapshot from grp 1 at size (the width of grp 1 * 2),(the height 
of grp 1 * 2)

If that produces an the image you need just change the command to an export 
snapshot command.

Import or export snapshot at current scaleFactor

[Terry Judd via use-livecode]

I’m automating the creation of a series of images (mostly graphs or similar) to 
include in some non LC generated reports and I need to be able to produce them 
at a higher than screen resolution so that they will look ok. I was thinking 
that I could just increase the scaleFactor of the stack and use ‘export 
snapshot from ’ to create the images but they are produced at ‘normal’ 
resolution. The workaround (I don’t want to have to recreate everything at a 
larger scale because I’m also using the same LC controls to print to pdfs 
directly) is to use the ‘export snapshot from rect’ but that requires that 
everything is visible on-screen and isn’t obscured by other stuff.

I don’t suppose there is any way to use the ‘export snapshot from ’ 
form and get it to capture the image scaled according to the scaleFactor? And 
if not, is there any chance of this being supported in the future (i.e. is it 
worth a feature request)?
