    did you know, that if you make a "vector" picture, you can englarge it as much as you want, and it never looks pixelated?

    that's because of something to do with vectorisation using lines, instead of squares like pixelated images do.

    But raster (pixelated) images are capable of holding more data per cell.

    I did not know that. How is this done, exactly? I've got some images I want to blow up, and I've got Photoshop, but no knowledge whatsoever about how to do this.

    I didn't enlarge the Megaman thing; it's just a direct link. He's not pixelated, he's just 16 bit. Not that there's anything wrong with that.

    Try ArcExplorer, I think you can download it for free. It's mainly a GIS program, but I'm pretty sure you can zoom in on pictures and save them that way. I don't think there are any types of manipulation, unless you convert it to a shapefile, which, you would then need ArcMap. And if I'm not mistaken, it costs a couple of G's and needs a good workstation...

    Then again, there may be a simpler way, but I don't know it...

  13. Vector graphics store the equations needed to generate the shapes in the graphic as well as other info, such as color, alpha etc. The computer then executes the instructions to generate the image. Raster graphics on the other hand contain color values for each pixel in the image.

    When you resize a vector graphic, the computer draws the shapes and fills them with color smoothly regardless of size, since the image is not tied to any specific pixel dimensions. If you enlarge a raster image say 2x (on each dimension) a 1 pixel square becomes a 4 pixel square, and the image editing program has to "decide" what color values to assign the new pixels - usually they'll be some blend of the original color and the color of the surrounding pixels, resulting in blurring.

    Think of it like this - vector graphics are to raster graphics (bitmaps) as midi files are to audio recordings. You can specify a new tempo for the midi file without losing audio resolution, but if you change the speed of an audio recording the data is affected.

    This is an oversimplification, but that's basically the deal.

    So, you can't really just convert a bitmap into a vector graphic, at least not so it looks identical. Flash can use raster images, but the drawing tools in it are all vector-based. Think of the cartoony-looking flash movies you've seen compared to photographic images for an idea of the visual difference.
