SIPS can do some basic image processing… What it doesn't lack is speed… 
You may want to look at MDLS too… You can check out its man page in the terminal app…
Here is a snippet of how you may be able to construct a list of files that contain transparency… ( I only did a quick check )
#target bridge
var f = Folder.selectDialog( 'Select a Folder to search in?' );
var shellString = "mdfind -onlyin ";
shellString += "'" + f.fsName + "/'";
shellString += " 'kMDItemHasAlphaChannel == 1 ";
shellString += " && (kMDItemFSName == *.tif || kMDItemFSName == *.psd || kMDItemFSName == *.png)' > ";
shellString += "~/Desktop/StdOut.txt";
The text file this creates should be your files…? You can read this in Adobe's ExtendScript and process the files or you could pipe it to SIPS…
Im not too good at that stuff thou…
No yellow blob here, it's behind the clouds and had rain this morning (saves me watering the garden )
Thanks you the both solution work! It is really nice to help me!
i note the following points:
- the javascript file work with .png but not with .psd ?
- the javascript code work slower
So i propose do to that:
- developpe a solution who call a shell script -> sips --getProperty hasAlpha ref_srgb_sans.jpg
- find a way to sort with smart collection.
Thanks you
I think this is the latest version of my little previewer…?
The one loaded is a binary and I can't remember when I last changed it…
I did it just for some fun… Was going to add some prefs but never got around to it…
Oh yellow… blob got to go… 
#target bridge
// One second window ( with yuk green matte )
function transSelectWindow() {
var png, prfs, win;
prfs = File( Folder.desktop + 'muppetspreview.txt' );
//if ( ! prfs.exists ) { prefsWindow( prfs ) };
png = File( Folder.temp + '/muppetspreview.png' );
if ( png.exists ) {
win = new Window( 'palette' );
win.text = 'Transparancy Preview';
win.margins = 0;
win.graphics.backgroundColor = win.graphics.newBrush
( win.graphics.BrushType.SOLID_COLOR,[0,1,0] );
win.add( 'image', undefined, png );
win.center();
win.show();
$.sleep( 1000 );
win.close();
png.remove();
};
};
// A window for the script prefs ( NOT done yet )
function prefsWindow( file ) {
var matte, win;
win = new Window( 'palette' );
win.text = 'Transparancy Preview Prefs:';
win.center();
win.show();
win.close();
};
// Use system to get PNG of file
function sipsGetPNG( file, size ) {
var shell = 'sips -Z ' + size + ' -s format png ';
shell += file.fsName.replace( /\s/g,'\\ ' );
shell += ' --out ';
shell += Folder.temp.fsName.replace( /\s/g,'\\ ' );
shell += '/muppetspreview.png';
app.system( shell );
};
// Define Bridge event handlers
onSelectionChange = function( event ) {
var h, w, m, thumb;
if ( event.object instanceof Document && event.type == 'selectionsChanged' ) {
if ( event.object.selectionsLength == 1 ) {
thumb = event.object.selections[0];
if ( /\.(ai||pdf||png||psd||tif+)$/i.test( thumb.name ) ) {
h = thumb.core.quickMetadata.height;
w = thumb.core.quickMetadata.width;
m = Math.max( h, w );
if ( m > 800 ) {
sipsGetPNG( thumb.spec, 800 );
} else {
sipsGetPNG( thumb.spec, m );
};
transSelectWindow();
};
};
return { handled: true };
};
};
// Register event handler ( on mac only )
if ( /Macintosh/i.test( $.os ) ) {
app.eventHandlers.push( { handler: onSelectionChange } );
} else {
alert( 'Sorry it\'s a mac thing…' );
};
Mark, I knew there had to be a reason why people used a Mac, now I know why!
I don't think this is available on a PC, the only thing I could find was the colorMode with a PNG of 4 or 6 that supports transparency but that didn't decide if it had transparency.
1 up for the Mac
Hi,
Thanks for this scripts! It works fine on my Mac
I have another question. How do you develop for Bridge? For example, if developpe in Java I use NetBeans and the javadoc to know the existing functions. With Adobe, the extendedToolScript does not propose the autocompletion. And SDK provided not the list of all functions. I have only codes of example.
I try to know how to do a smartCollection…
Thanks you!

Hi all, I wrote this! But it does'nt work yet! I'm bad in Javascript for Bridge 
#target bridge
var coll_without_profil;
var currentPath = app.document.thumbnail.spec;
// list of condition
searchCondictionList = Array();
var searchCondition = new SearchCondition('colorMode', 'equals', 'RGB');
searchCondictionList.push(searchCondition);
var scopeSpecifiers = Array();
var scopeSpecifier = new Scope('r');
scopeSpecifiers.push(scopeSpecifier);
var searchSpec = new SearchSpecification(searchCondictionList, 'and', 10, 'ascending', 'test', scopeSpecifiers);
createSmartCollection ();
function createSmartCollection(){
coll_without_profil = app.createSmartCollection( 'documents_sans_profil', currentPath, searchSpec);
}
