Hi @MaxZieb
I have been searching through the forum for examples of HTML2Canvas and want to screen grab the canvas with a resultant transparent background as an image and/or an animated video capture. I saw your examples of using HTML2Canvas, however, after researching I still haven't seen the light.
Two things I tried was to:
Checked background transparent option in Hype work area
Added option below in the javascript file.
backgroundColor : null,
Using your example link below to capture a transparent png image and trying different javascript combinations, the resultant images remains to not be transparent.
The idea is to screen grab my flipping pig as a transparent image and a transparent video file format.
Hi @h_classen:
Thank you for reviewing the challenge.
When I bring the HTML2Canvas saved file into a mac photo app on my computer, the resultant .png doesn't seem to have an alpha channel or transparent background. I would expect to see only the dark text without any white, gray or black showing in the background.
Also, if you have a full-size rectangle with a background color as an element in the container being captured, it will render in there. Either remove the element or set it to not use a fill.
If you need a background color in the preview, but not when capturing, just use the document background or a rectangle outside the element being captured.
Thank you @h_classen and @MaxZieb for showing me how simple this was in the end.
I played around with the BGC null variable and even changed element transparent setting and as usual, you feedback again made the difference.
