Colouring In Drag and Drop Browse Button CSS Tutorial

Some HTML features that interface to the underlying operating system, you may have noticed yourself, are more restricted regarding how you can style them, than the usual HTML element catalogue. One which is always coming up, in this regard, for us is …


input type=file browsing (from underlying operating system files) button

The thing is, as an improvement on yesterday’s Colouring In Drag and Drop Mobile Postcard Tutorial we’re butting up against this issue, because we wanted to make it more obvious for our mobile platform users of our Colouring In web application, that the way in to the functionality whereby they can create and share personalized (online) postcards is via them clicking that input type=file browsing button. And so we went looking for advice and came across this excellent link’s advice that got us to set up the scenario …

Colouring In Drag and Drop Mobile Postcard Tutorial

Yesterday’s Colouring In Drag and Drop Postcard Tutorial mentioned two issues with its Postcard creation functionalities that needed further attention …

We have more work to do regarding data limits (even with hashtagging) using mobile platforms and the Take Photo idea, and we have some text positioning to fix also …

… and today we look into that a bit more.

Regarding “We have more work to do regarding data limits (even with hashtagging) using mobile platforms” we were finding the “Take Photo” iOS Camera app functionality was producing images of more than 3000×4000 and as such, though amazingly it can still work in non-mobile, we were not surprised it didn’t work when shaping to create the mainly hashtagged email link required to share a Postcard with an emailee (ie. email recipient). So we did some pruning …

if (navigator.userAgent.match(/Android|BlackBerry|iPhone|iPad|iPod|Opera Mini|IEMobile/i) && document.getElementById('result').innerHTML.trim() != '' && lesserinurl == '' && document.getElementById('result').innerHTML.indexOf('data:') == 0) {

newimg.onload = function() {
// draw the image onto the canvas
//alert(11);
newcanvas=document.getElementById('mymobilecanvas'); //document.createElement('canvas');
//alert(111);
if (newimg.width > 800) {
newcanvas.width=800;
newcanvas.height=Math.round(newimg.height * 800 / newimg.width);
//alert('Wh=' + newcanvas.width + 'x' + newcanvas.height);
newcanvas.getContext('2d').drawImage(newimg, 0, 0, newimg.width, newimg.height, 0, 0, newcanvas.width, newcanvas.height);
} else {
newcanvas.width=newimg.width;

… using the great HTML5 canvas element invention, and found it could send such a pruned down postcard, though we are not ruling out future tweaks that may add back some resolution and size into the future. We’ll see.

And regarding “we have some text positioning to fix”, our hunch about the offset needed to fix being the (opposite of the) amount to the top of the imagery in a normal Colouring In webpage, panned out …
