This article mainly introduces how JavaScript + CSS achieves the auto-scaling menu effect of the imitation Mootools vertical bar, and enables the mouse to move over the menu item to display the auto-moving display effect, which has some reference value, for more information about how to use JavaScript and CSS to implement a menu of vertical auto-scaling animations like Mootools, see the following example.

This document describes how to obtain the image size and image proportional scaling by using javascript. We will share this with you for your reference. The details are as follows: Get image size: var originImage = new Image();function GetImageWidth(oImage) { if (originImage.src != oImage.src) originImage.src = oImage.src; return originImage.width;}function GetImageHeight(oImage) { if (originImage.src != oImage.src) originImage.src = oImage.src;

Sometimes, when uploading an image, because the image is too large, it not only occupies space and consumes traffic, but also affects the size of the image (the size of the image is different ). The following is a method for scaling images without distortion. In this way, no matter how large the uploaded image ruler is, it will be automatically compressed to the range where we set the size value. It has been tested and proved to be practical. Sometime

This example uses the example in "crazy android handout": paste it in person. The gesture from left to right is enlarged, and the gesture from right to left is reduced.

I recently summarized the image processing methods in Android, as follows: /*** Image inversion * @ Param IMG * @ return */Public bitmap toturn (Bitmap IMG) {matrix = new matrix (); matrix. postrotate (90);/* Flip 90 degrees */INT width = bitmap. getwidth (); int Height = bitmap. getheight (); IMG = bitmap. createbitmap (IMG, 0, 0, width, height, matrix, true); Return IMG ;} /*** image scaling ** @ Param bigimage * @ Param newwidth * @ Param newheigh

Scenecontrol + AE + scroll wheel Scaling To set the scroll wheel scaling for scenecontrol, you must define the delegation. Because scenecontrol does not have a wheel event, the from wheel event must be delegated. Public form1 (){Initializecomponent ();This. mousewheel + = new mouseeventhandler (this. sc1_wheel); // enter "This. mousewheel + =" in this place and press the tab key twice in a row.} Privat

From: http://www.cnblogs.com/yangws/archive/2011/07/22/2114132.html There is a headache with the development of games with Cocos2d-x, Android resolution is too much. Although Android supports full screen, but because the length and width ratios of different screens are different, a game designed for a resolution may be increased or squashed on other mobile phones, which is very ugly. The Cocos2d-x Provides proportional scaling that can be done w

For example, due to project requirements, the X axis is a timeline, which is relatively long, while the Y axis value is relatively fixed, while the zoom method provided by dynamicdatadisplay enables simultaneous scaling. I had to study the source code provided by dynamicdatadisplay. It is not difficult to find that the coordinateutilities Source Code provides the method to scale the X axis separately. The rectextensions also provides the corresponding

The most thorough method is to modify the animatedgifencoder, however, renhe needs to be honest, and he is suffering from the troubles.

The scaling effect of jQuery photos is not simply zoomed in and out of images, but does not affect the layout of other elements. If you need it, you can refer to the previous special effects on the Internet, but you didn't have a favorite website, as a result, I was not sure how this special effect was implemented. Today, I searched for it on the Internet, and I found it. I tried to write: However, only the image is zoomed in, and the layout of elem

than the nearest neighbor method. Of course, it also leads to a problem: that is, the image looks soft. In terms of professional terms, this filter is called: The Band resistance performance is good, but there is a band-pass loss, and the rectangular coefficient of the band-pass curve is not high. As for the cubic spline method, I will not talk about it. It is a little more complicated. You can refer to professional books on digital image processing, such as references in this article.
