5.8 gamma correction once the pixel values have been computed, we need to display them on a monitor. in the early years of digital imaging, cathode-ray tube (CRT) monitors were almost exclusively used. CRT monitors exhibit a power law relationship between input voltage and display radiance, which turns out to nearly match the inverse of light sensitivity of the human eye [1028]. the consequence of this fortunate coincidence i sthat an encoding proportional to CRT 来源: https://blog.csdn.net/wodownload2/article/details/100133743

How can I write a Windows application without using WinMain?

南笙酒味 提交于 2019-11-28 21:27:42
Windows GUI applications written in C/C++ have 'WinMain' as an entry point (rather than 'main'). My understanding of this is that the compiler generates a 'main' function to be called by the C Runtime. This 'main' function sets up the necessary environment for the GUI and calls into 'WinMain' (specifying the instance handles etc.). In short, I believe console and GUI application startup to differ in the following way: Console application: C Runtime --> 'main' function (hand-coded) GUI application: C Runtime --> 'main' function (compiler-generated) --> 'WinMain' function (hand-coded) I would

C++ Statically linked shared library

萝らか妹 提交于 2019-11-28 17:53:13
I have a shared library used by a another application beyond my control which requires *.so objects. My library makes use of sqlite3 which needs to be statically linked with it (I absolutely need a self-contained binary). When I try to compile and link my library: -fpic -flto -pthread -m64 -flto -static -shared I end up with the following error: /usr/bin/ld: /usr/local/lib/gcc/x86_64-unknown-linux-gnu/4.6.1/crtbeginT.o: relocation R_X86_64_32 against `__DTOR_END__' can not be used when making a shared object; recompile with -fPIC /usr/local/lib/gcc/x86_64-unknown-linux-gnu/4.6.1/crtbeginT.o:

I'm using Visual Studio c++ Compiler ( 2010 ), but the library has different implementation of ANSI C and POSIX libraries function. What is the difference between ANSI C function and Windows CRT implementation? For example what is the difference between tzset() and _tzset() or setenv() ans _setenv() ? It seems the do the same thing in the same way... I'm using msvc ( 2010 ), have I to prefer the Windows CRT Implementation? EDIT 1 Well I want convert in a portable way a struct tm expressed in UTC in a time_t , but there's no portable way to do that. I've to write the function for different

10个提升工作效率的Secure CRT小窍门 - 你玩转了几个?

10个SecureCRT 小窍门 - 你玩转几个? SecureCRT,相信不用我过多介绍了吧,一款通过telnet,ssh登录远端设备的终端软件。 无论是搞网络的,做系统的甚至写程序的,连接设备必用软件,容易上手,稳定性高,功能强大。 但是,面对SecureCRT密密麻麻的功能菜单,大家熟悉几个? 别把SecureCRT用成Putty 让我猜猜你平时怎么使用SecureCRT。 第一步:打开软件。 第二步:点开左边的会话管理栏,选择你要连接的设备。 第三步:双击连接,走你! 第四步:开始弹键盘协奏曲。 这应该是大家日常工作中,最频繁的SecureCRT使用习惯和方法吧。 但是,要光这样用,可能就屈了才了。SecureCRT的功能强大得让人受不了。 从基本的连接设备,到高级的运行脚本和python程序等,它都支持。 而今天,我就同你一起分享10个非常简单,但是又能让你的工作事半功倍的SecureCRT小窍门。 让你不再把SecureCRT用成Putty。 注:什么是Putty? Putty也是一款telnet和ssh的终端免费小软件。 功能单一,界面不是太友好,工作效率相比SecureCRT低很多。 窍门一:自动记录系统日志 配置网络或者系统设备,日志记录必可不少。 一方面记录设备的交互信息,方便后续追溯问题,在某些关键时候绝对能够帮你大忙。 例如配置过程中出现故障,你需要自证清白

Windows malloc replacement (e.g., tcmalloc) and dynamic crt linking

断了今生、忘了曾经 提交于 2019-11-28 04:23:52
A C++ program that uses several DLLs and QT should be equipped with a malloc replacement (like tcmalloc ) for performance problems that can be verified to be caused by Windows malloc. With linux, there is no problem, but with windows, there are several approaches, and I find none of them appealing: 1. Put new malloc in lib and make sure to link it first (Other SO-question) This has the disadvantage, that for example strdup will still use the old malloc and a free may crash the program . 2. Remove malloc from the static libcrt library with lib.exe (Chrome) This is tested/used(?) for chrome

How to execute some code before entering the main() routine in VC?

怎甘沉沦 提交于 2019-11-28 03:27:49
问题 I am reading Microsoft's CRT source code, and I can come up with the following code, where the function __initstdio1 will be executed before main() routine. The question is, how to execute some code before entering the main() routine in VC (not VC++ code)? #include <stdio.h> #pragma section(".CRT$XIC",long,read) int __cdecl __initstdio1(void); #define _CRTALLOC(x) __declspec(allocate(x)) _CRTALLOC(".CRT$XIC") static pinit = __initstdio1; int z = 1; int __cdecl __initstdio1(void) { z = 10;

How to install VC80CRT debug runtimes without full visual studio 2005?

谁说我不能喝 提交于 2019-11-28 02:57:21
问题 I can't run a debug sdk application because it requires both VC 8 and VC 9 versions of the CRT. But it only requires visual studio 2008 for plugin dev, which is what I need. How do I install the debug runtimes from 2005 on to a Windows7 machine? I can't figure out how to make them run app local nor can I copy anything into the winSxS folder without a trusted installer. 回答1: Refer to this post. As per this the debug dlls can be found at: For Visual Studio 2005: C:\Program Files\Microsoft
