export snapshot issue

Am taking a snapshot of an image control (actually any control shows the issue) but the returned image data seems to be broken.. If I export to a file, the file has the correct data.. Am using Rev Enterprise 4.0 on Mac OS X 10.5.8 (PPC), I tried with Rev 2.8.1 and got the same issue..
- create a new stack
- import an image on the card
- place a button on the card
- edit the script of the button (use the code below)
- click button
Code: Select all
on mouseUp
constant kObj = "image 1"
local tSs
export snapshot from kObj to tSs
create image
set the width of it to (the width of kObj)
set the height of it to (the height of kObj)
set the imageData of it to tSs
end mouseUp

Apparently one does not simply set the imageData of an image, but the text..
works

Hi Sean,
yep, that's right.
Although setting the text of an image is everything but intuitive and mentally highly challenging

No wonder I stay away from doing GUI related features

Hi All
Why not
Code: Select all
export snapshot from kObj to file MyFilePath
set the filename of last img to MyFilePath

Thanks for the tip, but trying to figure out where to store temporary files on someone else's machine is not always a nice thing to do so I was looking to do it all in memory

Hm, isn't the TEMP folder(specialfolderpath("temporary")) meant for these kind of actions?
I always used this in the past and never got sued!

But there is no point to writing out a file when it can all be done in memory.. That makes the code quicker and also causes less wear on the drive

OK, OK, lets agree that this might be a case of personal taste
