Save screen capture to camera roll?

Hi,
I am trying to figure out how to save a snapshot of a specific area of a card to the camera roll.
I have been experimenting with:
Code: Select all
on mouseUp
EXPORT snapshot from rect 0,30,320,350 to file "File1.png" as PNG
answer ("File Saved Successfully")
go to card "Home"
end mouseUp
But I don't think this is suited to mobile. I also found "mobileExportImageToAlbum" but have had no luck at the moment.
If someone could point me in the right direction that would be appreciated ! Thanks

Hi calmrr3,
I never worked with "mobileExportImageToAlbum" or something,
but of course you can also export a snapshot to file on MOBILE!
Just supply a valid pathname like:
Code: Select all
on mouseUp
put specialfolderpath("documents") & "/a_cool_screenshot.png" into tFile
EXPORT snapshot from rect 0,30,320,350 to file tFile as PNG
answer "File Saved Successfully"
go to card "Home"
end mouseUp
Best

Hi calmrr3,
I think you need set the paint compression and it should work
Try this:
Code: Select all
set the paintCompression to "PNG"
export snapshot from rect 0,30,320,350 to tImgData as PNG
mobileExportImageToAlbum tImgData
Best regards

I always thought that "the paintCompression" and "export snapshot... AS xyz"
would be independent of each other? Know what I mean? Not?

Hi Friend,
I don't know why but it works
I didn't find it alone, that was a suggestion of Simon in this thread

In that thread the OP used the "import snapshot" command which does not take any "...AS (format)" parameter,
so setting the paintcompression was mandatory there!
Anyway, that's just too funky that it works this way
