我如何在Linux上读取C JPEG和PNG像素++？ [英] How do I read JPEG and PNG pixels in C++ on Linux?
问题描述
我在做一些图像处理，我想在JPEG和PNG图像分别读取每个像素值。
I'm doing some image processing, and I'd like to individually read each pixel value in a JPEG and PNG images.
在我的部署方案，这将是尴尬，我使用第三方库（因为我已经限制在目标计算机上访问），但我假设有读取JPEG / PNG没有标准的C或C ++库...
In my deployment scenario, it would be awkward for me to use a 3rd party library (as I have restricted access on the target computer), but I'm assuming that there's no standard C or C++ library for reading JPEG/PNG...
所以，如果你知道的一种方式的不的使用库再大，如果不是那么答案仍然欢迎！
So, if you know of a way of not using a library then great, if not then answers are still welcome!
推荐答案
有在C标准不标准库读取文件的格式。
There is no standard library in the C-standard to read the file-formats.
然而，大多数程序，尤其是在Linux平台上使用相同的库脱code中的图像格式：
However, most programs, especially on the linux platform use the same library to decode the image-formats:
有关JPEG它的libjpeg，对PNG它的libpng。
For jpeg it's libjpeg, for png it's libpng.
该库已安装的机率的非常的高。
The chances that the libs are already installed is very high.
