Upgrade ToolAfter buying a camera, there are more and more images, and the minimum size is 1 MB. The transmission speed is too slow, so I want to resize all the photos. I found an image batch scaling tool created by Baoyu [Baoyu, openlab.net.cn] on the Internet.Code(Haha, I am lazy here. I thank Bao Yu ), I have added several new features based on my own needs (sub-directory scaling is supported and the sam

For example. You can use text-align: center; to center. Proportional scaling cannot be solved by using the width and height attributes of the preset . Because the user picture may be very long or wide. I thought about their relationship online and determined by the conditions as follows:Copy codeThe Code is as follows:If (actual width> maximum preview width ){Zoom width = preview max width}If (actual height> maximum preview height ){Zoom Height = pr

Android: scaleType controls the scaling mode of images. The sample code is as follows: 1 ImageView android:id="@+id/img" 2 android:src="@drawable/logo" 3 android:scaleType="centerInside" 4 android:layout_width="60dip" 5 android:layout_height="60dip" 6 android:layout_centerVertical="true"/> Note: centerInside indicates

Image ScalingI. The Pinch gesture scales the image. That is, drag the photo with two fingers in different directions, and the photo will be scaled down or enlarged.Principle I understand: proportional Scaling Let's take a look at the following key code: 1. initialization parameters -(Void) viewDidLoad { [SuperviewDidLoad]; LastDistance = 0.0; ImageStartHeight = self. scaleImage. frame. size. height; ImageStartWidth = self. scaleImage. frame. size. wi

JavaScript code for scaling window with animation Effects on the right side of the webpage, JS window This article describes how to implement the scaling window code with animation Effects on the right side of a webpage in JavaScript.

The scale mentioned here is not the size of the browser, but rather the percentage scaling of the content of the browser's Web page (by pressing the CTRL and + keys or the scale of the-number key).There are ways to detect this scale, and QQ space is used by flash to detect whether the browser is zooming. The JavaScript method is provided here to detect the zoom of the browser.For IE6, it is ignored, because IE6 can only scale the text.First of all, th

Many partners always think that the time to zoom picture is very troublesome, because do not know where to start, especially in the face of the new development language, in fact, there are many methods of image scaling, but original aim, that is frame, so, do not think so tall on. Here is an image scaling demousing masks, and interested partners can look at them.//Viewcontroller.swift// Zoom of picture//Cre

Original address: Dual linear interpolation algorithm for image scaling and performance optimizationA) transfer from http://handspeaker.iteye.com/blog/1545126A bilinear interpolation algorithm was recently used in programming to scale the image. There is a lot of information on the Internet, the introduction is also clear. However, these articles only describe the algorithm, and do not specifically how to implement and how to achieve the best, for exa

How does the win8.1 system prohibit automatic scaling of software at high resolution screens? win8.1 System has intimate, user-friendly design, such as software will automatically scale, what is the role of this? The software in the Win8.1 system automatically scales to fit the on-screen display, and looks clearer. However, if the win8.1 system resolution is good enough, there is no need to scale the software, or it will cause the screen to become unc

piece of code I also added one to the IE6 browser's judgment, besides it, I still lets the CSS fix the picture the size. I do not define the height and width of the image in the code, so when scaling, just modify one of the values, let another number to adapt, rather than let JS to perform the scaling, which is a little bit of optimization. I'm quoting jquery in my code (because I'm used to it), you don't
