based on screen resolution only. That is, the device is based on the screen resolution. This is also the source of the commonly seen VGA class name:Differentiate different devices according to different screen resolutions, such as some common names: QVGA: 240*320 Quarter VGA One-fourth meaning (for a quarter) HVGA: 320*480 Half size VGA meaning one-second (1 = a) VGA: 480*640 T

Php makes good use of regular expressions to process the Value nbsp, in the end, I will change the image resolution to 320*480, and the original image contains pixel information. Nbsp; e. g.: clear cabin (320*480) Wallpaper nbsp; in the end, php makes good use of regular expressions to process the values required in strings. Today, when collecting images from the Momo website, the resolution of the imag

Document directory Vector LOOKUP LOOKUP in array form Today, my sister asked me how to use lookup. I found this article on the Internet. It is still concise and concise, and I have posted it here after studying it.I personally think the two examples are helpful.-CTH Overview This article introduces how to use LOOKUPFunction. More information LOOKUPThe function returns a value in a row, column, or array.LOOKUPA function has two syntax forms:
