Finding Image Height Widht

hi ,

I have a image and have to find the image height & widht and then based on that I need to process further .

Is this possible from enfocus inbuilt variables. Or do I have to call external command to fetch this value.

I see Photo.PixelXDimension in script option but don't know how to use it .

Select "single line with variables" and select Photo->PixelXDimension

Thanks . But which flow element should I select for this and how I can use this in script .

I tried with below code in script

var imageWidth = job.getVariableAsNumber("[Photo.PixelXDimension]");

It is giving error Photo Object is not recognized.

So... I think what he is saying, you would have to have an element grab this value ahead of time -- said another way: he isn't explaining how to get this value inside the actual script.

What I would do is drop a "write to private data script" that writes the key "PixelXDimension" to value, select "Single line text with values". Then Photo > PixelxDimension. Then flow that into your script.

Now, in your script, you can do:

var PixelXDimension = job.getPrivateData("PixelXDimension");

Here's how I get info from any PDF file in a script. Photo should be similar.

var stats = new FileStatistics(filename);

var numPages = stats.getNumber("NumberOfPages");

var pageWidth = stats.getNumber("PageWidth");

var pageHeight = stats.getNumber("PageHeight");

and for a PDF job

var numPages = job.getVariableAsNumber("[Stats.NumberOfPages]");

var pageWidth = job.getVariableAsNumber("[Stats.PageWidth]");

var pageHeight = job.getVariableAsNumber("[Stats.NPageHeight]");

Switch doesn't come with one right out of the box but it's a pretty simple script (and very handy). Mine has a bunch of input values (Key1, Value1, Key2, Value2, etc..) and you can specify key and value pairs with single line text with values. Then just pass your job through and access the private data anywhere later.

The script is as simple as:

job.setPrivateData( key1, value1 );

If you can't figure it out, let me know and I can share mine with you.
