: How to scale aliased elements in Photoshop. I'm working with Photoshop for a few years now, but I've always had this problem that I didn't really understand or found a proper sollution for,

@Karen819

There is no way for an algorithm to know exactly how you'd like an aliased edge to look when resized. The program doesn't know what you're trying to draw. So if you try to resize a shape with absolutely no anti-aliasing whatsoever, you may get unwanted results. This problem has been somewhat curbed with the latest content-aware updates to PS, but it has not been solved for all cases, especially interface graphics.

That being said, if you want a slightly sharper way of resizing things in Photoshop, then go to Edit > Preferences > General and set the Image Interpolation option to Bilinear. That's probably the sharpest of the ones available, but it may create accuracy issues I will warn you. Once again this is simply because the program doesn't know what you want. You may, for example, have a space between two lines before resizing and no space after resizing. The program has no way of knowing that this space is important to you, all it sees is pixels.

That is called anti-aliasing. It does that because most folks want that most of the time. When rescaling entire files, you can use PhotoShop's "Nearest Neighbor" method of interpolation when scaling. For scaling vector elements, I believe you set up the grid in PS to use each pixel, and then it should snap to the 'whole' pixel.

Not sure how to handle resizing of raster elements.

Fireworks does a better job at this as it was designed specifically for web graphics, so its tools are more designed for that particular task than PhotoShop's.
