Hi all,

I have lyx 1.6.3 installed. I have to make a presentation and for that

pdf ( i.e. I make changes and then run pdflatex ,and changes are quite
frequent) the image starts getting kind of blurred and dirty.
What might be happening ?


Bitmaps formats are not the best, but ought to be ok for a presentation.
A bitmap that gets stretched may look bad. I find it very strange if 
your images gets worse as you edit your document - except if your 
editing consist of changing image sizes.


 But is there a
 particular image format that latex would understand 'better' than
 others ?

There are several vector formats, such as pdf and eps. These work 
better, _if_ you make images that really are vector graphichs. Merely

converting your jpegs to eps won't help, LyX do that automatically already.

Yeah that is one clever solution, I will use that. But is there a
particular image format that latex would understand 'better' than
others ?

 Hi,

 what I do is make nice graphs and pictures in power point,
 then save it as a pdf file.
 then upload the pdf file into the lyx/beamer document.
 It works great.

 One more thing, I even tried to make a pdf with just that pic so that

 How do I sort this out?

All image formats you are mentioning use pixels and not vectors, which
could result in blurry images when zoomed too much. Can you obtain
your images in a vector format, such as .svg or .pdf?

Perhaps you didn't scale well enough the picture. Try clicking on the
image and setting a reasonable percentage for the size of the picture.

Please reply to the list (where more people could help you) and

Hmm, autofit to a page, probably not. I think you would need to find
the right percentage by trial and error. Welcome to LaTeX!
