Android Zxing QR code scanning image stretching, In this project, the QR code scanning is integrated with zxing, and the image on the scanning interface is obviously stretched and deformed. Based on past experience, this problem is generally caused by misplacement of x and Y axes. The problem of x and Y axes can be solved. Because of this problem, many people have encountered it before and shared it online, so I don't need to repeat the wheel here. He

Commonly used picture stretch scenes are: Chat page bubbles, you need to stretch according to content, but the fillet stretch will deform, in order to avoid fillet stretching, you can specify the stretch area. The UIImage entity calls the following method to specify the extruded area.-(UIImage *) Stretchableimagewithleftcapwidth: (Nsinteger) leftcapwidth topcapheight: (Nsinteger) topcapheightLeftcapwidth indicates the width of the hat on the left (hor

There are two solutions: One is CSS, which uses background-size: cover to achieve image stretching. However, IE8 and earlier versions do not support background-size, so Microsoft filters can be used, however, IE6 does not. Body {background: url(bg.jpg) center; background-size: cover; height: 900px; width: 100%; filter: progid: weight', sizingMethod = 'Scale ');} The other is to use jQuery to dynamically insert a div into the body, and then include

In a certain direction, the gray scale value does not change, the pixel does not move. 5.

Stretching is simple, remember to set the backgroundsize to 100% when setting the BackgroundImage. If it is written in a CSS file. One small problem is that 100% needs to be enclosed in double quotes, like this: backgroundsize: "100%", or an error (really want to dozens AH). The repetition of the background is that when the background image is no larger than the container, the same picture is repeated on the container. The principle of this thing, of
