Jpeg figure quality deteriorating

Post by antonmaz »

Hello,

I am writing a paper, and need to incorporate figures. I have a ~20 jpeg files of high resolution. To get them to fit nice on the page, I had to scale them to 20-50% of original size. The more I shrink, the worse they look. Is it possible to shrink them without the loss in quality?

Thank you,

AM

How are you shrinking them? I'd probably do it using a specialist image tool, which tend to do better at working with JPEGs than simply scaling using TeX.

Pixel based graphics have to be scaled to three quarter of their original size to make them appear in actual size in the document.

Code: Select all

\includegraphics[scale=0.75]{filename}
The cause is the relation between postscript point (also called big point) and pixel. You can calculate that by yourself [1]. But previously you have to take this fact into account while creating your external graphics.
