All the raising trend of beautiful and great spirograph and spirograms with FF filters is very good and interesting, but as FF is slow to them in high resolution with good quality and antialising I thought that the best thing would be to convert this ones generated by FF to vector and so you could resize them all you want.
What would be the best way and best software to do it ?
I know that there are many different ways to do it, and would like to know how would you do it and what could be the best way for you.
Perhaps using Adobe Illustrator, Corel Draw, or another external or specific software.
Thanks for your help
It would be good that you could export directly these vector from FF, but of course to be able to do this FF must support vectors, so I wish that in FF 4.0 this could be possible |

Actually, even if FF had vector support, you'd porbably have to reconstruct the filter to use vectors from the start.
There's no real good way to convert full color raster images to vectors. Even Adobe Illustrator, with all it's might, doesn't do a very good job at this.
The best way to getr vectors out of rasters is to have very defined lines, with lots of contrast between them and the background. You need a medium resolution image, as low res will give you poor vector, and huge images will be VERY slow, and not necessarily better results.
Gradients are a big NO NO in raster to vector conversion. Try to use only solid colors.
Here are some examples that would NOT be good if converted to vector:
Gradient in the pink won't translate well at all. you'll get weird blobs of light colors on the pink.
Too many colors in a small space. You need solid colored areas.
Lines are too thin. You need thick, defined lines.
Here's an example that COULD become a nice vector:
While the white lines could be a bit more tricky, they are defined anough to work with. The rest of the image is built of large chunks of solid color. Just what raster-to-vector programs like. |

Yes, you are right that most probably it could happen that the filter would need to be rebuilt to be able to save the result as a vector unless there could be an new export option that could convert the result to vector, but this I think would be difficult and probably not possible.
BUT do you think that if FF ALREADY had support for vectors would you NOT make this filter from the start using vectors that I think would be perhaps easier to make?

YES, is true and I have some bad experiences trying to convert photos or color graphic images and illustrations to vector with very bad result, even using the most advanced converters.
When making this thread, I did NOT had in mind at all making COLOR conversions of the Spirograph results, because it would be like calling for problems.
The real intention of this thread is to convert the spirographs in just in BLACK AND WHITE solid lines or with some plain defined colors.

Thanks very much for this tips and suggestions. You are right in what you say and now thanks to you I remember some things I already learnt about this but have forgot that I knew.

Yes, Gradients, shades and transitions of colors can never be converted well because there can´t be a mix of vectors like you can mix the pixels to create that gradient or shade.

Magic does not exist in Vector world and would be impossible to convert this kind of graphics to vector

Absolutely true and you need very defined, clear and bold lines that can be translated and converted easily and right. As above the vector converter can´t make magic and be able to make vectors from this thin lines.

YES, is true that this could be converted well because as you have said very well, it contains all the needed and what the vector programs like. |
