Vector graphics

[Html]

http://en.wikipedia.org/wiki/Scalable_Vector_GraphicsI confused this with thinking that is has something to do with drawing shapes like the classic old style games?When it has to with images / fonts images files? Standards by the W3C

It has nothing to do with classic games. It's just a format of vectorial pictures.Maybe you're thinking of the screen types that old DOS games used (VGA).

Um, screen types? Like the ones that produce classic lines and stuff?

[Ingolme]

What are "classic lines"?

[Html]

Sort of like that, a lot more roughness.

Well, that does look like vectors to me, but I was quite sure that the early games actually used pixels. The remakes in flash might use vectors. Anyways, they probably aren't using SVG there, but it is vector graphics. Vector just means that it's not made up of pixels.Not all vector pictures are SVG, SVG is an XML based format for vectorial pictures.

What do you mean by Xml format?Yes, there is that pixel old classic games stuff. How can pixel style line be made? Besides something like a programming language?

Those are just lines. You might be thinking of anti-aliasing, anti-aliased lines have interpolated pixels around the edges to make the edges softer. Lines that are not anti-aliased are more jagged because you can't draw a straight line at an angle with a bunch of square pixels.http://en.wikipedia.org/wiki/Anti-aliasThere are usually settings with vector graphics if you want to anti-alias the lines or not. Vector graphics are different from bitmap or raster graphics in how they draw the lines. With a raster graphic it's basically just a grid of pixels (a bit map), where each pixel is a certain color, and the graphic is a certain size. With vector graphics instead of storing pixel information it stores information about the shapes. So you would have a line that starts at 50,100, is 100 units long, and has an angle of 45 degrees. That's the only information stored, not what color each individual pixel is. Vector graphics can be resized to any size and still be sharp. If you blow up a raster image it will start to get very pixelated and blocky the more you zoom in. The most common example of vector graphics is with Flash.If you want to see for yourself, go to adobe.com. Right now they have a movie on the top of their home page, it's a Flash movie. There are a bunch of pictures and some text. The text are vectors, and the pictures are bitmaps. If you right-click on the movie and click Zoom In several times you will notice that you can zoom in on the text as much as you want and it's still sharp. If you zoom in on the pictures they get blocky. That's the difference between vector and raster graphics.

Would anyone here know if flash can do something like that instead of something like just vectors?

I think Flash CS3 has a bitmap library. But it seems a little complicated to use.You can also load images into flash, which is much easier.All the images you see on this site are raster graphics. Every file with BMP, JPG, GIF or PNG extensions are raster graphics. Vector graphics are rarely used on the internet.

You can't draw raster images in Flash, you can import them though and use them. But you can still draw lines without anti-aliasing, if that's what you're into. You can even put a button in a Flash movie to turn anti-aliasing on and off.
