为了鼓励给的5星……

我其实怀着有所期待的心情,下载这个app。 显然,我失望了: 1️⃣我的清晰的试题照片,导入后成了模糊得分不清字数的毛玻璃——我哪怕用Apple内置的“图片转pdf”快捷指令,也不会出现降低画质到完全无法分辨字数的模糊。 2️⃣我有一个长截图照片,这也是我期待的功能,希望能根据图片的长宽比,把这个长截图分拆到几张PDF的页面上。很显然这个app只是在一张PDF页面上显示我整个的长截图。 上面1️⃣2️⃣两点显示这个app目前还不如图片转PDF的快捷指令。 但我打5星来鼓励开发者后续实现上面的功能,最基本的实现,只需要导入前,对于图片长宽比进行计算,然后适当缩放图片前,如果发现图片过长,以至于如果整体把图片显示在一页a4规格的pdf页面上时,宽会变得很小,那么这时候就要通过计算,来把长截图分解为多张符合a4尺寸的图片,分别放入多个a4的PDF页面。
