Yes I think you are right. python-imaging is the package mac os x uses to resize images and pdf. Thanks! -- Amit Uttamchandani [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

Re: How to reduce pdf file size with open source software?
IIUC, a pdf made out of an image will just be some kind of wrapper around the image (assuming you haven't first converted the image to text via OCR). How big was the original .png? You should probably resize that rather than the enclosing .pdf. Why do you even want to convert the png to pdf? Thanks for the quick response. You are right, the pdf is just a wrapper around the image file. The size of the png image is around 1.6 mb, the pdf file is around the same size as well. This is for a hw assignment and the prof. only accepts files in pdf format. When using the convert command, the png image is automatically converted to an 8.5 by 11 sized pdf document. I guess I'll have to reduce the size of the png image first and then convert it as pdf? -- Amit Uttamchandani [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Re: How to reduce pdf file size with open source software?
What kind of pictures do you have? Are they complex scene like pictures or simple pattern based chart? You could try to convert them to JPG by using low compression ratio and decrease resolution if possible. In addition, it would be better you import those pictures into OOo Writer and then export as PDFs. In the options of exporting PDF popup window, there is an option of adjusting quality and DPI of target PDF files.

Here's how I just handled a similar challenge. This is a real Rube Goldberg solution, but it worked... My wife handed me an OOo page saved as an 8.4 Mb .doc file with 8 X 1Mb embedded images sized to fit on the page with some text. She asked me to put that up on her web page, but clearly there had to be a better way to a) create such a page using scaled images, and b) upload it so it would be accessible as smaller download. After trying with little success to print or export the page to pdf (file size still too big), I took a screen shot! Bingo, success. I used imagemagick ($ import foo.jpg). New file: 125kb.

You can compose the whole document using the png images and then create one pdf (or per page pdf too?). There is also an option of the type of compression to use for images while making the pdf. But the first thing you need to make sure is that the images itself are of optimal resolution for your task at hand.

Then they don't need to be resized within the document. A 1mb image is pretty big at its native resolution, the object is to get it sized so that no resizing within the document is required. Then the attached images will be as small as they can be and still look good. Of course, .doc is not really a great way to put something up on the web anyway, but that's a different story and I'm surely not telling you anything you don't already know.

They are written text but composed of mostly math equations and quick, drawn out graphs. Have you tried to get the scanner working in Gnu/Linux? No option here, I use the scanner located in the computer lab on campus. If you are trying to create a math paper that needs 'complex math symbols', they you should consider (latex,tetex,texlive). You can also use tex to produce pdf files and include graphics files in those. Yes, I use latex quite often but I did not want to spend a lot of time typing up all those equations and plots. I just worked them out on paper and sent them of the professor. -- Amit Uttamchandani [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?
