This article mainly introduces the example of using imagecopyresampled function to implement image scaling in PHP image processing. This article first explains the knowledge of the imagecopyresampled function, and then provides an example of the implementation code, for more information about website optimization, see website optimization. content is also one of the objects to be optimized, and images are the most important content on the website. To

This article describes the function of adding watermarks to two images in php. For more information, see There are two ways to change the image size.(1): The ImageCopyResized () function is valid in all GD versions, but its algorithm for scaling images is rough. (2): ImageCopyResampled (), the edge of the image obtained by the pixel interpolation algorithm is smoother and the quality is better (but the speed of this function is slower than that of Ima

In the Web site development process, often to some of the pictures to do some processing, such as scaling, cropping, plus watermark and so on. Of course, these features can not only be used in the development of the site process, usually need to do some processing of the picture, the function is encapsulated into the function, to deal with the picture, according to their own requirements in the function to add the required parameters do not get it don

As we know, there is a scaled menu item in the Visio menu view, and as shown below, selecting the response option scales the drawing. In addition, its sidebar also has a drop-down list box, in addition to the choice of existing options, you can also enter a custom value, to achieve the custom scaling function. This article describes how to use C # and Visio SDK functions to implement various scaling o

Many WEB developers are likely to encounter this headache, that is, when the user to reduce or enlarge the page, the original good layout is destroyed. It is a big challenge for developers to allow web pages to support adaptive scaling and zooming out of the layout. In my opinion, if the user is consciously scaling the page, it should be known that scaling destr
