Random Specs: I use Ubuntu 12.04 LTS. I use Inkscape 0.48.3.1 r9886.
I was curious if how someone saves a .eps file in the future to include filters, effects, transparencies, etc. is being possibly worked on?
If not, is there an Adobe Illustration-ish version of a file extention that can be accepted from Inkscape onto Adobe Illustrator, that would allow the person who wants the design as an .eps, to save it as an .eps at their leasure? I know people may want their .eps file at the time of transfer, but, ugh. I don't know anymore...
If there's anyone out there that's using Inkscape on designer and business collaboration sites, how do you work around the .eps stuff when everywhere I turn, .eps files are of high demand? Any opinions about these .eps file problems, with Inkscape, Adobe and using inkscape for work would be very much appreciated!

At this point, I can not compete on these vector art design sites due to Inscape's .eps file saving capabilities are still young. While I know I can save my vector art as an .eps (and still keep it vector/ but everything's looks good straight, but if there's any curves, it's jaggy in those areas), I can't save any filters or affects that would make my designs "pop" and make them really shine, because the filters, effects, blurs, etc. are considered separately from the vectors as raterized images. At this point, I can't compete with a community of designers that have the advantage to add affects to their designs, because businesses don't want bland designs.
I know Adobe Illustrator is a very powerful tool, and expensive, which is why I'm using Inkscape, but I'm just curious what you guys do when you have to make/save something as an .eps? Do you just skip Inkscape on this and just do it in Illustrator? I've found other info across the Internet where certain illustrator postscripts may support, in one version the ability to keep/allow an option for transparency, where else, other postscripsts from other versions of AI may not (due to how it's designed again). Does Illustrator do a good job at saving everything you make in vector form as vector form (that also includes effects, blurs, filters)?
I've supplied a picture of snippets of a vector image I made (which I combined the images in Gimp but saved them at 200 dpi, so what you see is exactly what I see). The first two on the left are what they look like after I saved them as an .eps, post script 2, no rasterization (which means every effect I used that makes my image awesome is gone) , and set to page (or canvas for image area). I've used both script 2 and 3 options. I've done all the xml stuff and went through and made sure nothing is transparent anymore. The two images on the left, when they have straight lines, are ok. If there is any curves at all, it's jaggy in those areas. But this is what I see when I open the .eps file and I look at it in a document viewer. The two images on the right is how crisp they look when, still in the document viewer, when I zoom in, the objects are no longer jaggy looking and are in good shape. I feel that this is just a problem with how the document renders the image to the person viewing the image, and there's nothing wrong, no bug there. I'm just letting others know this just in case they've came across this "problem". In the document viewer, I can zoom in only so far, but it still looks clean, but kinda has this pixel look to it as shown on the images to the right.
Off topic:
I've read a few horrible instances across the Internet and here on Inscape about .eps files, and how using Gimp just solves everything when it comes to making an .eps file. I know there's a good chance I can be wrong with what I'm about to say, but if you feel it's wrong, please don't hesitate to respond back because I want to understand more about .eps and I can't troubleshoot because I don't have a $500+ AI program I can just drop my file into and save as an .eps. XD But there is a major, I mean major difference between an .ai file and an .eps file. I found out, at least it's suppose to work this way with Adobe Illustrator, that if you save a file in a .ai format, it's meant to only be opened with Adobe Illustrator. Where as .eps files are more of a flexible file to work with and be "easily" transportable across other native programs that also use and promote .eps files. Gimp is a rastorization program. As far as I know of, .eps files can hold vector, rastor or both in one file. If I save my image as a .png in Inkscape, bam! It's automatically rasterized! and if opened in Gimp and saved as an .eps, it will save it as an .eps file with rastorization. So this is great for companies that are in demand of their design as an .eps file, who's designs are rastorized. But what if I want my whole file and everything (including my filters/effects) to stay vectorized? If you want all your stuff to stay vectorized, do not go the Gimp route.The only thing I can gather is that, again, Inscape's .eps file saving capabilities are still very young. Please don't think at all that this is a hate comment slamming Inkscape. I very much appreciate what all you guys have done and I know it's continually getting better. I just wanted to get this out there, because there's still so much confusion going on when it comes to .eps file extentions (and I still don't know enough! D:). Also, I know it's definitely not your (Inkscape's) fault, but it saddens me that so many people/businesses/sites still demand a file extention that is heading for (supposedly) obsoletion. =(
If saving .eps files are never made to work any better from this point on in Inkscape, I still love it and will definitely continue using Inkscape for personal works. Looking forward to Inkscape 0.49! =)
