new "at size" clause in export snapshot

[Jan Schenkel]

Hi Chris,

It turns out to be a difference between the syntax as described in the dictionary, and the actual parser implementation.
The MCExport::parse method in cmdsf.cpp is written such that the 'at size' clause needs to come after the 'from' clause and before the 'to' clause.

A quick test showed that the following variant compiles and works:
##
export snapshot from tObj at size tWidth, tHeight to tData as PNG
##

In other words, you should go to the Quality Center and file a report.
RunRev needs to either update the dictionary or the parser code :-)

HTH,

Jan Schenkel.

 Has anybody tried out the new “at
 size” clause in the export snapshot command introduced in
 LC 6.6? I can’t get it to work. In fact, my script won’t
 even compile if I include it.
 
     export snapshot from tObj to tData as PNG
 at size tWidth, tHeight
 
 I’ve tried various uses of parentheses and can’t get
 anything to work. Can anyone help? I can’t find a specific
 example anywhere in the dictionary or in the release notes.
 I need this in order to get a retina resolution snapshot on
 the retina iPad.
 
 Thanks,
 Chris
