Re: Snaptshot of Browser Widget in iOS?

There are some JavaScript libraries that can convert an HTML page into an image 
(not just a canvas object) - that could be your backup if all else fails.

Snaptshot of Browser Widget in iOS?

[JOHN PATTEN via use-livecode]

Hi All!

I am trying to lay some objects (text fields, graphics, etc.) over a browser 
widget. I am essentially just taking a screen capture and then layering the 
objects on top of the image. Here is my script:

on mouseUp
lock screen
put the rect of current stack into tCoord

set the width of image 1 to the width of current stack
set the height of image 1 to the height of current stack
set the topleft of image 1 to 0,0
export snapshot from rect tCoord to file specialFolderPath("documents") & 
"File1.png"
set the visible of widget "browser" to false
set the filename of image id 1008 to ""
wait 2
set the filename of image id 1008 to SpecialFolderPath("documents") & 
"File1.png"
-- I believe i needed the three previous lines to get this to work for some 
reason???
show image id 1008 with visual effect dissolve slowly
unlock screen

end mouseUp


This works fine on my Mac, but when I test it in the iOS simulator it does not 
work. Is it not possible to take a snapshot of the browser widget in iOS?

Thank you!
