Re: [Dynapi-Help] image manipulation

[<mi...@pr...>]

Dan,

I know that this is just an oversite, or just a coding style that I am unfamiliar with, but on line 50 of dynaimage.js you have a method:

/*
DynImage.prototype.getImage = function (imgObject) {
	return this.img;
}
*/

and then on line 61, same method name again, totally different code, but without the 'prototype'...

/*
DynImage.getImage=function(src) {
	var img = new Image();
	img.src = src;
	return img;
}
*/

Also, I got a kick out of the alert debug that was left in there on line 38 :-) ... a coding style that I AM very familiar with!!

One last question (which is really still the same question repeated):

I assume that in the following line of code you responded with was just a change to make to your dynimage.js, in the set Image method, correct?

Then, create an "update" method which will dynamically change the image's width and height (this was my original question -- how to do this?), or should the update method be rewriting the IMG tag all together?

<!--
 <img src=file border=0 onload=update()>
-->


Thank you (in advance) for your advice,

You can retrieve the size of the image but it must be done after the image has completed loading.
