c - 灰度图像转换 .img 到 .ras - 在 Windows 中的 Linux 灰度中白色和蓝色？! C

Question

我想将 .img 文件(512 字节 header ，512x512 像素，每像素 8 位(值:0-255))转换为 .ras 文件。为此，我在本文末尾获取了 C 代码。我的测试图像 (test.img) 的输出应该是黑白图像 - 因此只包含 0 或 255 的值。但问题是，当我在 Windows 中编译 C 代码(从底部开始)时，我生成的 .ras 文件是白色和亮蓝色？!令人好奇的是。当我在 Linux 中编译 C 代码时，结果是完美的黑白？!怎么会这样呢？在这两个系统中我都使用 64 位。

所以你可以尝试一下:1. 编译 C 代码:gcc -lm img2ras.c -o img2ras2.通过控制台将.img转换为.ras:img2ras test.img test.ras3. 在 gimp、XnView 或 PaintshopPro 中观看 .ras 文件

您是否知道在具有相同版本的 gcc 4.8.1 的不同操作系统上如何发生这种尴尬的结果？

Answer 1

好吧，伙计们，我对此没有任何解释，但至少我让它工作了。如果我将 img2ras.c 代码放入我的 C++ 代码中(如本文底部所示)并在我的项目中调用它，一切都会正确吗？!所以这意味着:如果我通过命令行编译 .c 代码，我会得到一个蓝色图像，如果我在 eclipse 中编译相同的代码，我会得到黑白图像!这可能与 MinGW 和 cygwin64 有关吗？我很困惑，但同时又很高兴:)!
