Animated GIF SVG Slide Tutorial

The PHP GD library we use to help create animated GIFs (along with a whole lot of other help, it goes without saying) is not into vector graphics which is what …

  • Inkscape … as a vector graphics editor … and …
  • SVG … ie. Scalable Vector Graphics

… are really into … ooooohhh, aaaaahhhh … but luckily for us, the great ImageMagick offers functionality to convert a SVG image file into a PNG image file, via …

Non Windows Windows
convert infile.svg outfile.png magick.exe infile.svg outfile.png

… and we’re using that talent ImageMagick has to offer the user the chance, at any animated GIF slide textbox, the chance to enter encodeURIComponent and window.btoa sensitive entries whose (content) format could match (one of) …

… means by which a user can involve SVG input slides into their animated GIF creations in our changed PHP tutorial_to_animated_gif.php inhouse animated GIF creator web application further to yesterday’s Animated GIF Slide QR Code and Webpage Screenshot URL Tutorial.

Below is a new (PHP writes) Javascript iframe (iois object below) onload event function for recognizing hTTps://[HtmlWebpageWithSVG].html as above, and setting the iframe’s “src” attribute to its value …
