Animated GIF SVG Quiz Argument Tutorial

Animated GIF Creation Automation Arguments Tutorial
The automation measures in yesterday’s Animated GIF Creation Transparency Tutorial get an “arguments consideration” (maybe a five minute one, or perhaps ten minutes for “the outraged”) to help out ideas for our aspirational readers and users out there, who we are always keen to motivate, this Animated GIF Creator project potentially linked to user productivity, at its best.
If we want to improve automation ideas for these Animated GIF creations we need to use (initially ? and & “get”) arguments up at the web browser address bar for our exploratory user to not only allow for definition of …
- their hTTp style animated GIF slide content basis (in a “get” irefresh labelled optional argument) … but as of today, how about …
-
- new “get” dimensions labelled optional argument defines the output Animated GIF dimensions in terms of width,height … eg. 300,600
- new “get” title labelled optional argument defines the wording of the watermark style Animated GIF title (basis) … eg. My+Animated+GIF
- new “get” titlecolour labelled optional argument defines the colour of the watermark style Animated GIF title … eg. olive
- new “get” titlemode labelled optional argument defines the watermark style Animated GIF title mode … eg. All
… and please do not forget an optional argument
we’re always havingthat’s always been there … - the “get” delay labelled optional argument defining the delay between animated GIF slides … eg. 800
? That would complete some pictures out there, we’re hoping?!
Does this feel like a step sideways to you, “the regular reader”? We’d agree, and are a little surprised a revisit (to this project) shows this need, but there you are. Sometimes, revisits help clarify!
This means a changed (in large part to reorganize “argument related” PHP code to the top, now) PHP tutorial_to_animated_gif.php inhouse animated GIF creator web application can now handle …

You might have heard …

… deserves our consideration, we’ve decided, today … because …
Transparency begins at home.
We’ll just try our best here, but we have discovered a nuance that hadn’t tweaked with us before, considering “transparency” and using “canvas” elements. The …
[canvasElementContext].clearRect(0, 0, [canvasWidth], [canvasHeight]); // idea causes the canvas to become transparent ... different to the other concept like ...[canvasElementContext].fillStyle='white';
[canvasElementContext].fillRect(0, 0, [canvasWidth], [canvasHeight]); // this example idea causes the canvas to become white
It’s affected two “avenues of effect” (or is this a book?!) with our Animated GIF Creator logic …
- if a SVG+xml element data URI utf8 format representation mentions the word “transparent” we are now going to make the relevant helper canvas element background be transparent …

}
document.getElementById('mycanvas').getContext('2d').drawImage(this, 0, 0);
rdomURL.revokeObjectURL(rurl);
slideupdate(this, rslidename);
};
imgc.src = rurl;
}
“; ?>
… and … - the “+” means by which we involve our Scribble and Annotation helper (of animated GIF slide content) now has a new button (with its onclick event function) to ask about its main canvas element background colour …
function colourize() {
var huhcol=prompt('Enter canvas background colour or Cancel to ignore.', 'transparent');
if (huhcol != null) {
if (huhcol.trim() != '') {
if (huhcol == 'transparent') {
//alert(987);
//alert('topielem.width=' + topielem.width);
parent.document.getElementById('topcanvas').getContext('2d').fillStyle = huhcol;
parent.document.getElementById('topcanvas').getContext('2d').clearRect(0,0,parent.document.getElementById('topcanvas').width,parent.document.getElementById('topcanvas').height);
} else {
parent.document.getElementById('topcanvas').getContext('2d').fillStyle = huhcol;
parent.document.getElementById('topcanvas').getContext('2d').fillRect(0,0,parent.document.getElementById('topcanvas').width,parent.document.getElementById('topcanvas').height);
}
}
