Problems reading raster size

[Paolo Mistrangelo]

Hi list,

I'm having a random error trying to read raster size addressing paperscript variables from a js script . 

From Firebug:

TypeError: this._matrix.inverted(...) is null

this._bounds = this._matrix.inverted()._transformBounds(

paper.js (riga 9823)

This is the script...sometimes works, sometimes not. Either on Chrome and FF, trying to open the same images....quite strange

window.paper.project.activeLayer.removeChildren();

var imagePath = $('input[type=file]').val();

imagePath=imagePath.replace("C:\\fakepath\\","");

rastr = new window.paper.Raster(imagePath);

var wi=rastr.width;

var he=rastr.height;

var vw=window.paper.view.size.width;

var vh=window.paper.view.size.height;

if (he>wi) {

var scala=vh/he;

} else {

var scala=vw/wi;

}

window.paper.view.zoom=scala;

rastr.position =window.paper.project.view.center;

window.paper.project.view.draw();

I even tried to check the isInserted() method, but no luck!

Any help ?

Thanks

Paolo

that's probably happening because you access the raster before it's loaded?

Try wrapping the code in a raster.onLoad = function() {} block.

Thanks Jürg ...it works now!  But in Chrome I had to change view.size to view.viewSize (I still didn't get the difference between the two!)

Is the onLoad event inherited from js? I didn't know I can use it on raster object cause wasn't in your references....anyway thanks again.
