前序: http://mp.gaitu.com/sheji.html 这个是参考的网站. 其实这个做起来不难,就是有一些问题没搞明白。 名片制作的标准 文档大小是9厘米X5.4厘米的 分辨率是300 尺寸的大小是:1086x661
我是这样做的,弄一张1086x861的名片背景图, 文档大小是9x5.4 分辨率300 然后用做水印的方法在上面印文字。 结果....出来的名片..尺寸大小没变,但是文档大小变大了,分辨率也变了.(这就是我的问题).. 都说用户是傻子,不会用脑。下载下来之后,自然不会再去用ps什么的去倒腾一下。 我找了很久,没找着有什么办法可以让文档大小不关,分辨率不变.. 问问大侠们有什么高招可以指点一下不
补充一下:我用的是php GD库做的。

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
