Unable to create temporary image error

Hi,

I need your help, i want convert a png to a string, like this; u0089PNG..... etc

would you please help me ? I´m new in javascript

Thanks

Hi,

I think you can create a temp image, and write the image data into the temp image, then you can just load the temp image.

Here's an example

var win = new Window ("dialog", "Icon Button Example");

win.alignment = ["fill","fill"];

var grp1 = win.add ("group");

//store the data in a variable.

var tempImage = "\u0089PNG\r\n\x1A\n\x00\x00\x00\rIHDR\x00\x00\x00\u00EE\x00\x00\x003\b\x02\x00\x00\x00\x1F,\u00A3\u0084\x00\x00\x00\x01sRGB\x00\u00AE\u00CE\x1C\u00E9\x00\x00\x00\x04gAMA\x00\x00\u00B1\u008F\x0B\u00FCa\x05\x00\x00\x00\tpHYs\x00\x00\x0E\u00C3\x00\x00\x0E\u00C3\x01\u00C7o\u00A8d\x00\x00\x02%IDATx^\u00ED\u009B\u00DBn\u0083@\f\x05\u00F9\u00FF\u009FN\u0093\u0097JI \u0082\u00B5=\u00B0fx\u00AB\u00C4\u00FA2g\u0082z\u00A1\u00CB\u00C3K\x02-\b,-\u00B6p\t\t<TY\t\u009A\x10P\u00E5&A\u00BA\u0086*\u00EB@\x13\x02\u00AA\u00DC$H\u00D7Pe\x1DhB@\u0095\u009B\x04\u00E9\x1A\u00AA\u00AC\x03M\b\u00A8r\u0093 ]C\u0095i\x07\u0096\u00F7\u008Bn\u00DF\u00B7\u009F*\u00A3\u00D9~x\u00BC\u00F5%:S\u0097f\u00AA\u008C&\u00B9S\u00E5\u00D5\u00DB\u00D0A'l\u00A6\u00CAhh\x11\u0095\u00F5\u00FBwT\u00AA<\u00B7\u00CA\u00FA\u00FD\u009F\u009F*\u009F\u00A9\u00F2\u00B3w\u00FAs\u00FA\u00B6\u00DF\x7F\u00A3*c\u00B1\u00CD\u00D2h\u00EBc\u0084\u00CD\u008F~\u008E\u008B\u009Bq*c\u00F1L\u00D4\u00E8P\u00B8\u00D8^\u0087\u00A6\u00BA\u00CE\u00CD\u00AA\u008C\x19\u00B2\u00D2(\u00EE\x016}|\u00D4\u00EA\n\u00AA\u008C\u00C9P\u00A2\u00F2\u00AA\x1F\u00D8J\u00D5v\x1E\u00AA\u00AF\u00CAX\u00EE\u009F\u008D\x0E\u00E5\x14\u00BC\u0099\\28\u00EA\u00F0\u00F1\u00D3T\x1E\u009E\u00D8\u0083Y\x040\u00BF\u00B3\x06\u00BE\u00CA\u00EF\u0095}\u00F7\u0080I4\u00D8e^\u00BF}*\x07\u00A3\u00BF\u00C5\u00F1:\u00BF\x13\u00F1\u00A9r\"\u00CC{\u0095\u00CA\u00F2;\u008B\u009A*g\u0091\u00BCc\u009D\x14\u009B\u00B3\u00C0\u00A9r\x16\u00C9\u00E6uR\u00AC\u00FD.\u0092HM\u0095\x13a6)Udm\u00A9\u00C7O\u00F4\u00AA\u00DC\u00C4\u00BF\u00B15&\u00B5v\u00FD\x0FCc\b\x06Na\u00D4fi4\u00C00r\x04\u00C3\x12\x192r\u00F6\u00B4\u00A72F\u00F6\u00CA\u008D\"\u00C9\u00FD8\u008B\u00AD\\4\u00FFXYU\u00C6r/y\x07\x03\u009B~L/\u00F2\u0094*c2DU\u00C6\x06%\u00FDK\u00EC\u00C5\u00A9\u00FC\u00FA\x19\u00D3\u00EB\u009D\u00C0V\u0090\x18\u00A7D\u0093N/\u0085\u00AA|\u00FA\u00B6\u00A7\x0F\u00F0\u00FD\"\u008A\u00D6f\u0085\u00A2\u00CAY$w\u00D5a\u00C4\u00DD5J\u00BB\u009BT\x19\u008D4]et\u00FAk7Se4\u009F\u0088\u00CA\u00E8\u00A0\x136Se4\u00B4\u009D*\u00A33ui\u00A6\u00CAt\u0092\u00FE\x0BB\x11qU.\x02kY\u009A\u0080*\u00D3\u00C4\u00EDWD@\u0095\u008B\u00C0Z\u0096&\u00A0\u00CA4q\u00FB\x15\x11P\u00E5\"\u00B0\u0096\u00A5\t\u00A82M\u00DC~E\x04T\u00B9\b\u00ACei\x02\u00AAL\x13\u00B7_\x11\x01U.\x02kY\u009A\u0080*\u00D3\u00C4\u00EDWD@\u0095\u008B\u00C0Z\u0096&\u00F0\x07\u0088TW@\u00CC4\x14\u0090\x00\x00\x00\x00IEND\u00AEB`\u0082";

Let me know if it help

Hard to say really, what version AE and OS are you running? My first guess is that maybe the source image's file permissions or it's parent folder permissions may have changed somehow causing an error. Place a try/catch around all your image retrieval code and see if you can get more clearer info about the issue.

try{

//your code

}catch(err){

alert("Error at line " + err.line.toString() + "/n" + err.toString());

}
