    Vector Magic

    Not really software, but a really nifty <img src=/S/free.gif border=0 alt=free width=30 height=15> web service: VectorMagic

    "This site traces bitmap images, turning them into beautiful vector art. Just upload your image and we will convert it for you."

    It converted the JPG photo (below, left) into a SVG image (below, right) ... not a bad effort I think.

    Re: Vector Magic

    Sorry for asking what must be an ignorant quation to many but what is the advantage of a vector image and how does it differ from any other image? In the sample you showed, it looks to me as if the vector image has less somewhat detail than the original. I don't mean this as a criticism... just trying to understand what point I have missed.

    Re: Vector Magic

    A bitmap (or jpeg or gif) image will look blocky ("pixelated") if you magnify it.

    A vector image can be blown up to any size and the boundary lines between the colors will remain smooth. This is because a vector image doesn't contain pixel-by-pixel information, but mathematical descriptions of the boundary lines.

    Re: Vector Magic

    Okay, thanks.Now I understand.... this is a cool find. Had I gone to the website first (where it is explained), I could have avoided the question here... lesson learned.

    Re: Vector Magic

    With my apologies for the not-normal large size of this, I thought I'd post a real-life example. I have been messing with an updated userpic, so I made both an EPS and SVG copy of a JPG my daughter-in-law took at a picnic this summer. Here's a combo of yours truly in living color...

    Al

    What application do you use to render EPS?
    I don't think anything I have can deal with them.

    Re: Vector Magic

    Not at all... fair question. Usually, vectorization is not the method adopted for scaling photographs and usually the results on photos vary from terrible to very terrible. I used a photo here though, to demonstrate just how good a result this site seems capable of. More often, vector graphics are used for things based on well defined shapes with distinct edges - for instance, the pictures used in cartoons, comic books etc. Their value for me has been in the display of charts, graphs etc. The reader can zoom in or out, to any degree on any region, and see an exact sharp representation of what's there. As Hans said, the graphic is actually redrawn according to formulas, with each view, so it always looks precisely the way it's meant to look.

    Far too obvious. I could never have been expected to think of that! <img src=/S/grin.gif border=0 alt=grin width=15 height=15>

    I know that most of the Major image programs on can save as for the EPS type files.

    Now running HP Pavilion a6528p, with Win7 64 Bit OS.

    Re: Vector Magic

    PSP v7 also opens them Al. I have some line drawings in EPS format and Irfanview opens them just fine. But it wouldn't open the EPS file created with this site's software. I opened it with PSP v7.

    In the spirit of the season...... (I've cropped & resized this image 5 or 6 time now and can't get the width down. Anyone know what I'm doing wrong??)
