What file is GIF?
Online common small animation is mostly GIF format, also known as frame-by-animation, is composed of a number of pictures together (there are also single-frame). It uses lossless compression technology, as long as the image is not more than 256 colors, it can reduce the size of the file, but also maintain the quality of imaging. GIF is divided
To the users of Photoshop software for detailed analysis to share a simple GIF animated pictures of the production of a tutorial.
Tutorial Sharing:
First look at the effect:
PS there is an option to do a GIF map, to set their own
PS Each version is not the same, this is PS5, you can try each of the workspace window out of the following page is like this
Solve | problem | Optimization This question is too much to ask. So I think it is necessary to explain again.
First of all, flash output image distortion is not surprising, because the flash output image quality is not good control. Furthermore, Flash is not a professional image processing tool, he is an animation tool, which is related to his own nature.
So the flash output image quality is not good don't ask again.
Here's how to fix it:
In fact, you can use flash output AI format or other v

Photos and complex images using JPEG
Monochrome images, logos, and geometries using PNG or GIF
JPEG is best suited for continuous-tone images, such as photos. can represent images with up to 16 million different colors. This is a "lossy" format because some information about the image is discarded when the file size is reduced. Transparency is not supported. The file is small so that the Web page is displayed mor
Photoshop can enable the existing GIF animation, but only Shields this function. we can enable the animated GIF through [File> Import> video frame to layer], as shown in, by default, only MOV, AVI, MPG, and MPEG video formats are enabled, but no GIF is available. Photoshop can enable the existing GIF animation, but onl
For the Web front-end development of students, picture preservation format is very important. So how to choose the format of the image saved? Below I summarize the difference of picture format such as Gif,jpg,png.GIF is an image format that is applied very early. It uses the LZW compression algorithm, the LZW algorithm is to replace the long string with a short string method to achieve compression. GIF supp
Because a project needs to convert a set of continuous photos into animated forms for transmission, we have studied this aspect, later, we found a project named NGif In the open-source project. Through the methods provided in this project, we can directly implement this requirement. However, I found that this project is not directly written in C #. On the contrary, it calls a Java class and converts it to C # code, this is certainly not within the scope of our research today, because this projec
PHP is not just used to create HTML output. It can also be used to create GIF image files, or even make GIF image streams easier. To do this, you need to use the GD function library to compile the PHP source file. Example2-2. using PHP to create GIF files this example will be used by a page with SyntaxHighlighter. all similar:
PHP is not just used to create HTML
Recently, I have been studying the implementation of GIF on Android and have some experiences. Now I want to share it with you.
At first, I saw the implementation of GIF on my mobile phone. It was an application of GIF kuaishou on the iPhone. I felt pretty good and wanted to implement it on Android. I checked it later. In the past, there was also a
Last two days, I encountered a technical problem. When I extractedMathML from GIF image generated by mathtype, there were always junk characters in the MathML text.
I had discussed this problem with my colleague, he told me to replace the MathML text with image. But I thought it was not a perfect solution. Then I triedTo get help on the Web. As usual, I searched something in Google. I found an answer in similar question on stackoverflow: "Convert math
In recent days, I have been working on the GIF file format. I found one on the Internet and I am analyzing it. It can be said that GIF images are relatively complicated in several image formats. To put it bluntly, we should first implement a method to export images from GIF Animation:
The effect is as follows:

PHP has encountered some problems dynamically generating GIF images, which is now resolved and I am using php4.05 (for Win32) +apache3.1.2_win32. Problem One: A program that dynamically generates GIF does not turn up I wrote an example about using PHP to generate GIF, running and discovering that the page is not going to brush out, like it was dead, The brows
A basic principle of realization
In the introduction of the specific implementation process, the first simple to say the basic principles and implementation steps, in the solution of relatively complex problems, I am accustomed to first clear the main principle of the steps, do not start by the cumbersome details of the trip, waiting for the specific implementation and then one by one. The following are the main steps:
1, video file reading: including recording and local file reading
2, the n

Examples of generating GIF images are not found on the Internet. However, many watermark files are generated. If we make GIF images into watermarks, the images will not move. So I wrote a small example for your reference. (If you want to print a dynamic icon on an image, this class can be well implemented, provided that you must first break down the dynamic icon into several separate
In order to give the software login interface an animation effect, it is decided to use GIF animation.
However, MFC does not have a standard control that can directly play GIF videos. The cpictureex class is found online. After installing a tutorial and writing the entire project, you can only display one frame of GIF. No animation effect. It turns out that the
