lossless converter

This article mainly introduced the PHP solves the picture lossless compression question, now shares to everybody, also gives everybody to make a reference. The code is as follows: Header ("Content-type:image/jpeg"); $file = "111.jpg"; $percent = 1.5; Picture compression ratio list ($width, $height) = getimagesize ($file); Get the original size//scale Size $newwidth = $width * $percent; $newheight = $height * $percent; $src _im = Imagecreatefromjpeg

Problem the default Ctrl + C copy out the image of the serious blur, copied out of the original picture! because the image size has been modified and copied out is blurredSolutions solution put word If this picture is reduced to see what it looks like with a slight CTRL + Cthe picture is very small, the picture is very blurryRestore the picture size to 100% after zooming and then make sure that the picture and the original image is the same,

to JPEG. pngquant --quality=65-80 image.png --speed N, -sN Speed/quality trade-off from 1 (brute-force) to ten (fastest). The default is 3. Speed ten have 5% lower quality, but is 8 times faster than the default. --iebug Workaround for IE6, which only displays fully opaque pixels. Would make pngquant almost-opaque pixels fully opaque and would avoid creating new transparent colors.

I bought some CD last year and copied it with EAC on the PC and compress it into an ape. After the CD is sent, the missing CD is lost. Later, I switched from PC to Mac. Because iTunes does not support ape, I converted it into ALAC. Apart from a small number of ape s, they survived because they were misplaced, and all the other ape s were cleared. I recently added Vivo to try those songs in the natural environment. Unfortunately, Vivo won't be able to play those ALAC. What makes people laugh most

Non-destructive adjustment of Linux partition capacity the simple tutorial is only to make the partition adjustment in Linux easier. If it involves partition adjustment in dual systems, especially the addition/deletion of partitions, it is a little more complicated. Gparted-LiveCD is recommended for www.2cto.com. I. Preparation 1. download the latest gparted image file. 2. Burn the gparted image file into a CD or press it on a USB flash drive to form LiveUSB. 3.

However, the notebook business in the pre-installed WINDOWS8 system does not consider the user experience, a 500GB or 1TB hard disk partition into a separate hard disk, such zoning method is not in line with our users use the computer habit.

Blank field in actionform The blank field of actionform indicates that when this input field is not in the form, the El expression is used to take the value and the JSP script is used to take the value. The other is that the form contains this input field, but there is no value. The El expression is used to take the value and the JSP script is used to take the value. The result is as follows: There is no input field in the form. The value received by the JSP script is null, the string is nul

Type converters for struts (in this case a date type converter) One, type converter1, struts in the data submitted by the JSP (all STRINGL type), struts will be automatically converted to the corresponding type of properties in the action, (this is better than servlet,servlet need to manually convert).2. For basic data types and date types are automatically converted.3. The date type only supports YYYY-MM-DD format. In other formats, you need to custo

Most of the time, we use struts 2The built-in type converter can meet most of the type conversion requirements. However, in some special cases, if you want to convert a string into a composite object, you need to use a custom type converter. To implement a custom type converter, you must follow these two steps: 1, Write your own type
