Canvas via Imge Web Share API Tutorial
We’re on the lookout for ways to improve the sharing and collaboration functionality of yesterday’s Images to Canvas No Clicking Form Signature Tutorial‘s “User of Signature” canvas using web application. We’re calling on ..
- Safari and Google Chrome web browser(s) … for the moment, supporting the …
- Web Share API … in order to …
- Fill out email (or other communication idea) attachment links or documents … that …
- Prepare the message before you, the user, flesh out the message as you send it off to the recipient
… a more guaranteed way, these days, because there are more and more ways restrictions may stop you doing similar functionality with a mail server arrangement on your public domain website, where we use the Exim mail server, at the RJM Programming domain.
As far as data goes for this, we also call on ourchanged PHP helper signature_signature
php to create a webp image file for sharing …
<?php
if (isset($_POST['webpit'])) {
file_put_contents($_SERVER['DOCUMENT_ROOT'] . DIRECTORY_SEPARATOR . 'canvas.webp', base64_decode(explode(";base64,", str_replace(' ','+',urldecode($_POST['webpit'])))[1]));
exit;
}
?>
… as applicable. The modus operandi for this back at today’schanged web_share_api_testjs external Javascript Web Share API specialist, uses Ajax methodologies …
var canvc=' ', lastcanvc=' ', czhr=null, czform=null;
function cstateChanged() {
if (czhr.readyState == 4) {
if (czhr.status == 200) {
if (1 == 2) { alert('Did it'); }
if (document.getElementById('shareurl')) {
document.getElementById('shareurl').style.backgroundColor='yellow';
}
}
}
}
function tctowebp() {
var ourcanvc='';
var canvs=[];
if (window.top) {
canvs=top.document.getElementsByTagName('canvas');

if (eval('' + canvs.length) == 0 && window.top) {
canvs=top.document.getElementsByTagName('canvas');
}
}
if (eval('' + canvs.length) > 0) {

return ourcanvc;
}
… and set in motion via a couple of different parental calls such as …

Images to Canvas No Clicking Form Signature Tutorial
Surprisingly, it’s been more than a year since we changed anything to do with our …
- canvas based …
- images and annotation … accepting …
- scribble (ie. can handle signatures) … perhaps …
- form filling helping web application
… (when we presented Canvas Graphics Editing in Zoomed Webpage Tutorial) and we found that in order to add six more such Annotation option helpers into the mix …
| Image Input Mode | Image Sizing Modus Operandi |
|---|---|
| URL | Actual (canvas resized to image) |
| Contain (canvas) | |
| Cover (canvas) | |
| Browsing | Actual (canvas resized to image) |
| Contain (canvas) | |
| Cover (canvas) |
… we only needed tochange the external Javascript signature_signaturejs code used by oursignature use in canvas supervisory web application so that when you can not ask so much of the user regarding image scaling, and avoid any canvas clicking that way, offering these six new annotation functionality options.

Canvas Graphics Editing in Zoomed Webpage Tutorial
Software integration can be useful for a number of reasons …
- code reuse
- modularisation of functionality … and in our case …
- if you like coding via “intervention points” you will enjoy coding for software integration improvements
As you might imagine it is easier in terms of the fact you can change “both ends” of the software integration, if it is “inhouse”, and luckily, today, our software integration is “inhouse”.
When we presented the recent Keyboard Based Cursor Canvas Content Copy Tutorial it focussed our attention on an improvement we could make to that user_of_signature_signature.htm canvas image editing web application. We wanted to offer the software integration with this web application to be able to successfully handle a webpage that has been zoomed to zoom factor different to 1.0 (or 100%).
We noticed before today’s very simplechanges to external Javascript signature_signaturejs code, graphic positioning on the canvas was wrong when the webpage had a zoom factor that is not 1.
Applying the canvas co-ordinate references through “the lens of” Javascript function zmb below …
var zzfac=location.search.split('zoom=')[1] ? decodeURIComponent(location.search.split('zoom=')[1].split('&')[0]) : "";
if (('' + location.hash).indexOf('zoom=') != -1) { zzfac=decodeURIComponent(('' + location.hash).split('zoom=')[1].split(';')[0]); }
function zmb(inco) {
if (zzfac != '') {
if (zzfac.indexOf('%') != -1) {
return eval(eval(eval('' + inco) / eval('' + zzfac.replace('%', ''))) * 100.0);
} else {
return eval(eval('' + inco) / eval('' + zzfac));
}
}
return inco;
}
… used in the following example code below …
topelem.addEventListener('mousedown', function(event) {
if (topin) {
topin.value='- -' + isScribble + ',' + lastx + ',' + lasty + ',' + x + ',' + y;
}
if (isScribble == 1) {
threebackpmore=twobackpmore; twobackpmore=lastpmore; lastpmore=pmore; pmore=' pxam1 ';
isScribble=2;
if (event.pageX || event.pageY) {
ppx=zmb(event.pageX) - elemLeft;
ppy=zmb(event.pageY) - elemTop;
} else {
ppx=zmb(event.clientX) - elemLeft;
ppy=zmb(event.clientY) - elemTop;
}
if (pdgebi(topdcmcheck('dcm'))) {
if (parent.document.getElementById(topdcmcheck('dcm')).value.indexOf('text') == 0) {
//parent.document.title='here3 ' + tx + ',' + ty;
if (1 == 2 && tlx < 0 && tly < 0) {
tlx=ppx;
tly=ppy;
}
if (tx >= 0 && ty >= 0) {
prevtx=tx;
prevty=ty;
trotis=eval(((Math.atan2((ppy - prevty), (ppx - prevtx)) * 180.0 / Math.PI) + 360) % 360);
if (pdgebi('trotation')) {
if (parent.document.getElementById(topdcmcheck('dcm')).value.indexOf('textseq') == 0) {
jsrectbits[0]=prevtx;
jsrectbits[1]=prevty;
jsrectbits[2]=ppx;
jsrectbits[3]=ppy;
if (Math.abs(prevty - ppy) > Math.abs(prevtx - ppx)) {
trotis=eval(((Math.atan2((prevtx - ppx), (ppy - prevty)) * 180.0 / Math.PI) + 360) % 360);
}
}
parent.document.getElementById('trotation').value=Math.floor(trotis);
ppx=prevtx;
ppy=prevty;
prevtx=-1;
prevty=-1;
exceptwhen=endtrue(''); //true;
if (parent.document.getElementById(topdcmcheck('dcm')).value.indexOf('textseq') == -1) parent.document.getElementById(topdcmcheck('dcm')).value = 'Text';
}
//alert(trotis);
}
tx=ppx;

} else {

});
… we now have reasonable graphic positioning for the canvas when its webpage window has a non 1.0 zoom factor applied.

Keyboard Based Cursor Canvas Content Copy Tutorial
You may have noticed with yesterday’s Keyboard Based Cursor Share Content Copy Tutorial, crucial to the sharing code, was the use of the incredible HTML5 introduced canvas element, helped by that middleperson link to those public email and SMS sharing conduits, overseeing the great random Lorem Picsum background images and user created emoji and/or text initial annotations.
And this got us wondering whether there was a private (ie. inhouse) web application of the past that could further value add as another optional middleperson tool for (user) personalization (of the content) purposes. And yes, do you remember the canvas work involved in the featured web application of Emoji Borders and Backgrounds Canvas Annotation Tutorial?
It uses an interesting approach with the transference of data across from a canvas in one application to the canvas in that user_of_signature_signature.htm web application. Once ourchanged body_mouse_deepdivehtml‘s “parent” web application has organized its canvas contents, it’s just a matter of …
var awo=null;
awo=window.open('./user_of_signature_signature.htm','_blank','top=100,left=100,width=800,height=800');
for the “child” canvas annotator to effectively “suck up” the canvas data into its canvas via …
var cancont='';
var elemode=location.search.split('elemode=')[1] ? (location.search.split('elemode=')[1].split('&')[0]) : "canvas";
if (('' + window.opener).replace('null','') != '') {
var cans=window.opener.document.getElementsByTagName(elemode);
if (cans.length > 0) {
if (elemode == 'img') {
cancont=cans[0].src;
} else {
cancont=cans[0].toDataURL('image/png');
}
if (cancontw < 0 && canconth < 0) {
cancontw=cans[0].width;
canconth=cans[0].height;
}
}
}
... possible because both "parent" and "child" exist on the same RJM Programming domain (web server).
Once there, another woooooorrrrrlllddd of image manipulations, via canvas, can await the user, perhaps ready for ongoing sharing possibilities with that "child".

Yesterday's Keyboard Based Cursor Personalized Content Copy Tutorial has probably reached a point where some sharing mechanism is apt, for accountability and usefulness purposes, at the very least, regarding our recent web application allowing for foreground content on top of a random Lorem Picsum background image.
