Heavy pdf

[gtsolid]

Hi,

I notice the attached pdf is almost empty but very large. It was made starting from a CAD software.

How can I investigate this issue?

The property tab is quite silent

Go to File menu : Save As Other : PDF Optimizer.

There's just a bunch of unnecessary info saved in it, probably from when it was distilled. If you use the Save As command and save it under a new name you'll see a dramatic reduction in size.

Your "extra baggage" in your PDF is a .jpg image for some reason...

The file name ends with : "...4024384437981.jpg"  (1914x2480 pixel size). Does that ring familiar?

It's obviously doesn't show when you view it or print it, so it seems to be a ghost of maybe an image that was deleted?

I did a resave of the the file (as has been suggested) and the reference to the jpg is gone and the file reduces in size accordingly. So there's something freaky going on in the workflow of whatever CAD program you are using.

Not familiar at all. Where can I get this reference?

[Brad @ Roaring Mouse]

This is the image.

Yes, it's the watermark. But where is it?

[Brad @ Roaring Mouse]

It's buried in the code of your PDF, but perhaps suppressed from printing? That's something to track back to your CAD program as to why it's including it when making a PDF when it's not necessary. Regardless, that's what's adding to your file as the JPG by itself is 1.5 MB

How did you dissect the pdf?

[Brad @ Roaring Mouse]

PDF format is like Postscript in that it's pretty much a text file. I just opened the file in a text editor and scanned through it for anything unusual and found the .jpg. I just extracted it into a separate file.
