Sort Vector Art from Bitmaps

[Guest]

Hi,

I have a folder containing over 2000 eps files and need to separate these into raster images and those containing vectors.

The script I am using opens each file in turn and uses the first layer name to determine if the file has been rasterised or not. If not then I update some meta data and close and save the file. If the layer name is "layer 1" I assume the file has vector artwork and has been rasterised, I then close the file without saving changes.

____________ the script__________

var samplesFolder = Folder("J:/Extracted_Standing_Artwork/Non_Customer")
var fileList = samplesFolder.getFiles("*.eps");
for (var i = 0; i < fileList.length; i++) {
if (fileList instanceof File) {
var fileRef = new File(fileList);
app.open( fileRef, );
var layer = app.activeDocument.activeLayer.name;
var filePath = decodeURI(app.activeDocument.path);
var fileName = decodeURI(app.activeDocument.name);
if (layer=="Layer 1"){
app.activeDocument.close(SaveOptions.DONOTSAVECHANGES);
}
else{
app.activeDocument.info.author = "Bitmap"
epsSaveOptions = new EPSSaveOptions()
app.activeDocument.close(SaveOptions.SAVECHANGES)
}}}

__________ end ____________

The result is raster files in the folder with a very recent modified date and untouched vector files.

Can anyone please suggest a better way of doing this.
It is possible to test for the "Rasterize Generic EPS Format" dialog box?
Can a javascript then "move" the vector files into a new folder to leave just the rasters in the orginal folder.

Any help would be appreciated.

See if this thread helps http://www.ps-scripts.com/bb/viewtopic.php?t=1113.

It shows how to test for generic eps files

Thanks for the prompt reply Mike,

I have used you script from the link given but with mixed success.
The script will identify a text file with and with the string "Adobe Photoshop" but does not find the string in an eps that does contain it!

I can see the string if I open the eps in notepad but the script does not see it.

Any ideas?

Simon.

If you are able send some sample files to mhale18 at comcast.net and I will take a looks at editing the script.

Here is a slight change to the function. It works correctly with the sample eps you sent.

function isGenericEPS(file){
var test = file;
test.open('r');
var str = test.read();
test.close();
var res = str.search('Adobe Photoshop');
return res == -1 ? true : false;
};

Mike,

Thanks for the modified script. It did the trick beautifully. Can I ask you one further favour?

Could you explain what each line is doing so I increase my understanding of scripting.

Thanks

Line 1 defines the function.

line 2 sets the file object from the argument to the var test. This line is not really needed, I could have just used the file argument. It's likely a hold over from a previous edit.

Line 3 opens the file in read mode.

Line 4 reads the entire file and assigns it to str.

Line 5 closes the file for good housekeeping.

Line 6 search the string in str for 'Adobe Photoshop' and assigns the result to res. res will either be -1 if not found or the start position in the str if it was found.

Line 7 tests the contents of res and either returns true or false. This line could be rewritten as an if statement

if( res == -1){
res = true;
}else{
res = false;
};
return res;

Line 8 closes off the function block.

Hope that helps

Mike,

I don't suppose you would know how to do this in a VB script?

Simon.

I haven't tested this and my VBS is not that strong but this should be close

Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.OpenTextFile("C:\temp\Text.eps", 1)
str = objFile.ReadAll
objFile.Close
pos = InStr(str,"Adobe Photoshop",1)
' if pos is not 0 the the string was not found
if pos = 0 then
' do whatever you need to to for generic eps
document.write("Generic")
else
document.write("Raster")
end if
