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。

Response from developer

Hi! Thank you for your feedback. I am sorry for your disappointment, especially since in the test groups we never encountered loss of quality for images. It is true that images are compressed to 150dpi and adapted to A4 but we did not see significant loss of quality. I will take it into consideration and see how this will improve the app. Thank you and have a great one!
