Re: LyX: Using GIF Images?
Sorry but I came late to a thread about using images under lyx. I read this on the web and I'm new here. I tried to convert for my first time a jpeg image to a ps image issuing the following commands: $ convert photo1.jpg photo1.ps $ convert -antialias photo1.jpg photo1.ps $ convert photo1.jpg eps:photo1.ps and also specifying other "eps" formats like: $ convert photo1.jpg ept:photo1.ps and so on with several options like "-depth 16" or "-density 300x300" or "-colorspace RGB"... But I read in some msg. that "converting image/* .jpg ps" shouldn't result in loss of quality. The same thing happens to me using The Gimp. In a strange manner, if the NEW eps image is viewed with "display photo1.ps" it looks great, but gv shows a very different image with remarkably LESS quality. Maybe I'm confused and different "EPS" formats have different extensions, other than ".ps"? So: Can anyone be so kind to issue the _EXACT_ command to convert any "conventional(?)" image format like .bmp .jpg .gif .bmp or .tif if there is any? TIA. -- José Albores - [EMAIL PROTECTED] Linux 2.2.5-15 i586 running
Re: LyX: Using GIF Images? : XV does a very good, albeit interactive, job at image conversions !
XV does a very good, albeit interactive, job at image conversions ! load the image in any format, and then save it as Postscript (with the extension .eps), don't forget to set the compression (which is only available for 8 bit colour images and reduces the image size by a factor of 10 compared to non-compressed.) XV also offers easy ways of editing and reducing the colours. Ofcourse you can also use PC-based tools like Corel Draw. The quality has so far never disappointed me for technical purposes. Good luck !

On ven, 07 jan 2000, Nemeth Miklos à écrit images were always (much) larger than the original GIF or PNG. one must know that gif png images are compressed ones - without loss, jpeg are also compressed ones but with some loss of quality. by the way ps and eps don't seems to be compressed. the real problem is there, images can be VERY big. if your document needs high quality image to be flashed on postscript composers, you will soon send et burned cd to your printer... -- Le site ci-dessous est surtout consacré à Linux, mais aussi aux nouvelles de science fiction écrites par moi, à la pédagogie de la dao et à plein d'autres choses que vous allez manquer si vous n'y allez pas voir! http://perso.club-internet.fr/jdanield [EMAIL PROTECTED] - [EMAIL PROTECTED]
