Adobe Acrobat : Lacks Reverse Engg
All those surf have come across a pdf file somewhere on the net. We as an engg students always come across the engg material provided in a pdf file due to its structure - a pdf file does not require additional fonts, its formating does not change from PC to PC.
But did you come across some files when you cannot copy contents from the files? (I'm not talking about the secured/locked files.)
So how does it works? Why doesn't it require those fonts used in it to be installed?
Well, the Acrobat Writer adds the fonts to the file- so the pdf file carries the fonts used in it!
But, here is a problem again.....This makes the file bulky...So what to do?
The Writer thus uses a technique called 'Subsetting the fonts'! What it actually does is - it includes only those characters which are used e.g. if I have used "Space Age" font to only write "Hello" then only H,e,l and o are included in the file.....This reduces the file size.....
The biggest problem arrives here! if you try to copy the contents of such file in another file, you will notice that the copied contents doesn't make any sense - its all garbage!
And on top of that - After searching for at least 3-4 months on net - I came to know that - YOU CAN NOT DO ANYTHING TO GET THE CONTENTS!!!!!
Thats ridicules!!! You can not reverse the process!!!!!!!
(BTW, there is a way to get contents of such files - Use OCR "FineReader" - its not a efficient way but at least you get what you want!!)
