One more confusion to complete the discussion: In website design and layout, one "CSS pixel" is always equal to 1/96th of a "CSS inch", regardless of screen resolution. This was done because so many early websites used pixel-based measurements for layout assumed a standard screen resolution. In order that the actual size of text and other content ...

The term "pixel" is short for "picture element". An image has consists of pixels, which are just colored dots in a rectangle, with no size. To show the image, we use a screen that can show colored dots, and need to decide which dots we want to show where. Looking at the details, the image consists of separate dots, each with a separate color. Like when ...

If a client of mine asked for a 1920x1080px image, the first thing I need to know the intended use. Is it for the web, print, or both? In the print world, a pixel (or picture element - [pict-el]) has no meaning or definition. Pixels can not be measured in any way. They have no predefined size or unit in order to calculate their size. Therefore are not a ...

A pixel has no correlation to real world measurements. As such, there is no way to convert inches to pixels in any consistent way. It's all arbitrary and dependent on what you're doing to do with the image int he end. What is a pixel in the context of a digital image? It's the smallest unique element within the image. It will have a color assigned to it. ...

Inches are physical dimensions while pixels are screen dimensions. At the same resolution, a pixel is physically bigger on a larger screen, as the density or PPI (pixels per inch) is controlled by the screens physical size vs resolution. So when converting pixels to inches, it all comes down to what you want your pixels per inch (PPI) to be. If you want ...

Just think of pixel like Atom, Atom is a smallest particle of matter. Where as Pixel is a smallest particle of Digital Image. Atom has Neutron, Proton & Electron where as Pixel has Red, Green & Blue values :) Number of pixels per Inches or CM etc... is called the Resolution Higher Resolution means More pixels per unit of length like. If you are ...

The solution to the problem that @plainclothes stumbled upon is to turn of the align to pixel grid within the symbol, but turn it on for the instance of the symbol that is placed on the canvas, by clicking on the x or y links on the info bar and enabling "align to pixel grid" just there. It basically means that your instance will snap to the pixel grid on ...

You need to have pixel preview on for it to work. To enable that, just go to View \ Pixel Preview on the top menu. That is what actually enables the snap to pixel mode in illustrator, which cannot be done any other way. Checking align to pixel grid is not a good option, unless we are talking about elements made of square angle (90 degrees) lines, like ...
