Re: Fun with the templateimage

[Bernard Devlin via use-livecode]

This works:

export snapshot from rect tRect of window tWinID at size tDim1,tDim2 to
file tFile as GIF

I saw a report in the forum saying that this scaled incorrectly if the
snapshot was of a text field, but in my tests this was not a problem.

Richard, just FYI

The dictionary (LC 9.5.1) does say that "export snapshot ... at size
x,x..." is supported since version 6.0, but I can't get it to change the
size of the exported image.  I'll add a note here if I get it to work.

## Just tested with DO, this does work WITHOUT switch 8-)
put "export the templateimage to file " & quote & pDestFile & quote & " as" && 
pFormat into tCommand

Re: Fun with the templateimage

[Richard Gaskin via use-livecode]

The "import snapshot" command had an "at size" option added several 
versions ago to facilitate some scaling tasks:


   import snapshot from the selectedObject at size 100,100

But oddly, no such option has been added to the "export snapshot" command.

Fun with the templateimage

[Klaus major-k via use-livecode]

Hi all,

we know that "the templatexx" is a very helpful thingie.

But I was really surprised that we can even EXPORT something
from the templateimage until I tried this:
-
on mouseUp

  ## My good ol' banana, older users of MC might remember that one :-D
  set the filename of the templateimage to "/Users/klaus2/Desktop/BANANA.jpg"

  ## This was a know (to me) feature
  put the formattedwidth of the templateimage into tFW
  put the formattedheight of the templateimage into tFH
  ## Now you can apply some "rule of three" to scale the image while preserving 
its ratio
  ## I'll leave that up to you... :-)

  ## I cheated a bit:
  set the width of the templateimage to 181
  set the height of the templateimage to 252

  ## But this one really suprised me:
  export the templateimage to file (specialfolderpath("desktop") & 
"/eltesto.jpg") as JPEG
  reset the templateimage
end mouseUp
-
No image object involved, how cool is that?! :-)
