Hi i have a lot of image reading in my app and when I load the files i use CGImageGetWidth and CGImageGetHeight to get the sizes of the images.
然而,这似乎并没有在任何时候都恢复正确的价值。
例如,如果我有114x14人的图像,这些功能将退回126x22,或像这样的随机。
真正的奇怪部分是,它并没有发生从建筑到建筑的所有时间(变化),但往往发生在同一组图像上。
因此,我有某种不了解的编码错误,或者这些图像给他们带来了某些环境,使他们的处理方式不同。
任何人都知道可能产生这种行为?
