  • Stretching an Image without it becoming Crap

    Is it possible? How?

    I'm talking about enlarging a small image such as this one:


    Without it becoming all crappy looking with really stretched out pixels, and not by holding the shift key while dragging outwards.

    Vector graphics: data is line start/end/color/thickness - can be resized without loss of quality.

    Raster graphics: data is coordinates of pixel and color - can be made smaller ok, usually. but making larger is a problem as you have to come up with data for pixels which did not previously exist. different algorithms available, i did a quick bicubic in photoshop and came up with: ... it's not great

        raster graphics is a term, for graphics made of pixels. I used Photoshop for the resize, using the Bicubic algorithm.

          There is an art group called Rasterized (http://www.rasterized.org). All their stuff is raster art (although most art in general is raster art)

              The method of graphic storing which stores each pixel with it's colour value (the one which isn't vector graphics) is more commonly known as bitmap.

                bitmap is a filetype, not a method of anything :P

                  Well, I searched on Wikipedia for "bitmap" and it automatically redirected to Raster Graphics:

                  A raster graphics image, digital image, or bitmap, is a data file or structure representing a generally rectangular grid of pixels, or points of color, on a computer monitor, paper, or other display device.

                  I guess they're synonymous.

                    I don't need the 'rasterbator' because it enlarges images to that of the size of sheets of paper. I just want a better, cleaner image when I go to Stretch it for my desktop.

                        if you've got photoshop yoiu can also piss about with filters

                        heres rabs one with a simple blur filter on it



                        it doesn't do much but it helps smooth out the image if the enlarging has made it blocky/pixalated , it does this at a price of course but you can piss about till your happy with it

                          Ah, nevermind then. I was already trying to blur it using The GIMP anyway.
