Rasterizing Generic EPS Format in Photoshop 7

[selenus]

I have sources in EPS format. I need convert it into JPEG or PSD. I has worked with .PSD sources only. I need get hi-resolution images, JPEG format.
When open EPS file, Photoshop show 'Rasterize Generic EPS Format' dialog, where I need select desired dimensions, resolution, and mode. This dialog show dimension and resolution(72dpi), that is much smaller that I want get. Also, it show CMYK color, not RGB. I need get large dimensions and high resolution(150dpi), so I specified the required dimensions and resolution. Since my dimensions/resolution is much larger that default data shown in dialog, will this decrease quality of JPEG? Or this is not affect on image quality? Also, should I flatten image before saving?

Any ideas?

EPS is a container format that can contain both raster and vector info.

If the eps is pure vector, common for things like corporate logos, it can be rasterized to any resolution with no loss of detail. If the eps has raster info in it, the resolution would be dependent on the original raster settings.

One way to check whether an eps has raster in it is to open in a vector app like illustrator. Then blow it WAY UP. If it's all vector, everything will stay sharp and tight, expecially object edges. If there's raster info, thing will get fuzzy.

This EPS contain pure bitmap 100% - digital photo. I dont know why they used such strange and non-standard way - put bitmap in .EPS container. What I need is get hi-quality image for web. The better way is use PSD source, since I need resize it, etc. I assume, Photoshop show initial resolution in 'Rasterize' dialog, that is read from eps file. It show 72dpi - if this correct info, its low, and there is no sense to specify 300dpi? Also, I want set large image dimensions, how this will affect on image quality? Does it make sence use proportional ratio? (i.e. if initial height is 7.66px, so I set new height 15.32px (7.66 x 2). Or this does not affect? Then , does it make sense save it in PSD format?

If it's bitmap you're sort of stuck with that resolution. As long as it's for screen display (as opposed to print) you can play with it in photoshop and see how it looks.

Try open the eps at 300-600 dpi and see how it looks. You can always reduce resolution later.
