Can Ti.Paint load Blob as background ?

You must Login before you can answer or comment on any questions.

Hi, I have a question. I can put an image form a file to Ti.Paint. sample code like this, var paintView = Ti.Paint.createPaintView({ image : '/images/djsp.jpeg', top : 0, right : 0, bottom : 0, left : 0, }); Ti.Paint can show the image.

But When I use a Blob to Ti.Paint, the Ti.Paint can not show the image. sample code like this, var paintView = Ti.Paint.createPaintView({ image : blob, top : 0, right : 0, bottom : 0, left : 0, });

Please help me, Thanks very much!

I'm not sure is possible, but you always can save the blob and pass the nativePath to the image property.

  • This method (mentioned by Dan) is probably your best bet.

  • Thanks Dan vary much. I use a way to solve the problem. the sample code likes this,

    var filename = Titanium.Filesystem.applicationDataDirectory + "/image.jpg"; var img = Titanium.Filesystem.getFile(filename); img.write( blob );

    Ti.Paint.createPaintView({ image : filename, top : 0, right : 0, bottom : 0, left : 0 });

    I will try your way, when I have more time. Thanks your help very much.
