Thanks , Claudio You can gzip the PS (or better EPS) files. This makes you save quite a lot of megs. But you need to extract the bounding box information first and put it into a separate file. This leaves you with one image.eps.gz and one image.eps.bb file. LaTeX and xdvi should be able to deal with these compressed images automagically. Unfortunately, LyX is not yet able to display them. But you can still use them without problems, you simply need to turn display off in the figure popup and change the name of your image from image.eps to image.eps.gz in that same popup. Below is a little script that can do the trick on hopefully any PS and EPS file. Thanks a lot Claudio

Hi Claudio, I have a similar situation, but I don't know if my solution will help you. I have an electromagnetic simulation program that generates very large ps files (up to 80MB) for three-dimensional structures. I use the GIMP to sample the ps file to a desired resolution (this just means that I open the .ps file inside the GIMP). Then, I convert the file to .gif which usually results in a file that is less than 250kB. I then use xfig to create a figure with the .gif file in a picture box, and finally, I export to eps from xfig. The resulting .eps file can be used in LyX. My 50MB ps files become 200kB gifs and 500kB to 1MB eps files. Unfortunately, this may not help to compress your 3MB ps files if they are already efficient. The memory size of bitmapped/compressed images depends strongly upon the final dimensions: if you need a thumbnail image, say 80x60 pixels, it will have a smaller size than the original one, say 400x300 (that is a good reason to use specific small images in HTML documents rather that resizing of original ones). The size of vectorized images is by definition independent of the printed size (a global scale order changes the size at viewing or printing time). So - if the original ps is of the vector kind, nothing can really be done, unless the used software produces very huge dictionaries of macros which are not fully used by the figure; in that case I would suggest to try a conversion to eps using ghostscript: it may rewrite a simpler picture; - if the original ps is big because bitmapped, convert it to GIF or PNG, then back to eps, preferably in the final desired size; ImageMagick allows to do this in batch mode (i.e. without opening the images) quite easily, which is useful when you have many images. Unless you print in color, you will convert to greyscale on the fly (-colorspace GRAY option of ImageMagick convert command). As a side remark about the original mail, I don't understand why the size of the image is a problem, once it is converted in EPS: to produce the dvi, LyX only needs the BoundingBox, the image in only read at viewing or printing time: if the printing fails, I would suspect a printer spool problem or a temporary size. Did you check that ? A good test is to save as LaTeX, run latex alone and chack that the dvi is correct. Then you may try to print the document page by page dvips bar -pp1-1 Regards, -- Jean-Pierre
