我很想知道,如何做以下工作( could,帮助我这里):
- I got a .jpg file of about 250px*250px in scale..
- I want this image on a DIN-A4 page as often as possible
- I need an "overlay" for every image on the page with a unique code ( lets say a unique barcode for example )
怎么会开始? 我实际上没有任何想法来为之提供哪类或方法。
了解哪些“格式”即可在......中创建文件也是令人感兴趣的。
感谢任何帮助!
