How can I let the png images pack into .jsx files?

Hi,Bob

Thanks a bunch.It does work well.

I just ran this on a good png and got good output.

var f1 = new File( [png path] );
var f2 = new File( [text file path]" );

if ( f1.exists ) {
f1.encoding = "BINARY";
f1.open( "r" );
var buf = f1.read();
f2.open( "w" );
f2.write( buf.toSource() );
f2.close();
f1.close();
}

TO Bob,

I have tested with "png.exists"，it returns "true"!

I have no way to find the problem!

Goldbridge

Make sure that the File objects reports png.exists == true

Bob

I can't get the code like this (new String("\u0089PNG\r\n\x1A\n\x00\x00\x00\rIHDR\x00\.... ),it only returns "(new String(''))" ,anyone can tell me why?

read "binary"

TO Bob,Peter

I have placed the png image(1.png) into "c:\ButtonBar".

Then I run the script:

/***********

var png = new File('/c/ButtonBar/1.png' );
var f = new File( '/c/ButtonBar/2.js' );
png.open( "r" );
var buf = png.read();
png.close();
f.open( "w" );
f.write( buf.toSource() );
f.close();

/************

But this script doesn't work,it only returns this code "(new String(''))" in "2.js".

Can you tell me why?Thanks a lot!

Bob,Peter:

My friends,thanks a bunch!
Bob's answer is very well,I'm going to have a try!

To Peter:

How can I save the script(included a png) as jsxbin?

When he said "pack" them into the jsx files, that's what came to mind.

I use the technique when I want to have a set of images, but don't want the user to have to deal with putting images into correct places.

A new version of my script library uses it for a widget that adds a flyout menu to any ScriptUI window, for example. I don't want the user to have to put an image in a correct place, so the script does it for them.

You can save it as a jsxbin.

The only thing to watch (that I've found so far) when saving to jsxbin are classes that get serialized with toSource().

For example, in my lib, the Hashtable and Preferences class will have instances serialized and reconstituted...

From the lib:

BobsLib.Preferences.prototype.load = function() {
var oldLevel = $.level;
$.level = 0;
if ( this.file ) {
if ( this.file.exists ) {
this.file.open( "r" );
var buf = this.file.read();
this.file.close();
var obj = eval( buf );
this.merge( obj );
} else {
$.level = oldLevel;
throw "Preferences Not Yet Saved";
}
} else {
$.level = oldLevel;
throw "Preferences File Not Set";
}
$.level = oldLevel;
this.wasLoaded = true;
}
BobsLib.Preferences.prototype.save = function() {
if ( this.file ) {
this.file.parent.verify();
this.file.open( "w" );
this.file.write( this.toSource() );
this.file.close();
} else {
throw "Preferences File Not Set";
}
}

After a Preferences instance is saved, it can't be loaded because the eval() fails. Looks like the constructor isn't available as text causes the problem.
