So I have this problem. I have an IplImage that i want to compress to JPEG and do something with it. I use libjpeg8b.The code exit when it goes the function of jpeg_start_compress() with an error of "Bogus input colorspace" .Here are my code. #include "highgui.h" #include <stdio.h> #include "jpeglib.h" #include "cv.h" #include <iostream> #include <fstream> using namespace std; using namespace cv; #pragma comment(lib, "jpeglib.lib") bool ipl2jpeg(IplImage *frame, unsigned char **outbuffer, unsigned long*outlen) { IplImage *img = new IplImage; memcpy(img,frame,frame->nSize); unsigned char

libjpeg8 include are those two functions, but in libjpeg-turbo has the following: //jconfig.h #define JPEG_LIB_VERSION 62 ... //jpeglib.h #if JPEG_LIB_VERSION >= 80 /* Data source and destination managers: memory buffers. */ EXTERN(void) jpeg_mem_dest JPP((j_compress_ptr cinfo, unsigned char ** outbuffer, unsigned long * outsize)); EXTERN(void) jpeg_mem_src JPP((j_decompress_ptr cinfo, unsigned char * inbuffer, unsigned long insize)); #endif if i try to use "JPEG_LIB_VERSION 80" i'll get the following: error LNK2019: unresolved external symbol _jpeg_mem_src referenced in function ... so, how

I am getting an error where reading the same lena.jpg file on two different computers yeilds two different checksums. Even weirder is that when I run md5sum lena.jpg I get the same md5 sum on both machines, so the files are identical. Furthermore, when I load a png instead of a jpeg the numbers seem to match up. This leads me to believe there is a disconnect between Pillow on the two different machines, or at least the library they are using to read jpeg files. Is there any way to check which version of libjpeg is being used by Pillow (from within Python preferably)? Both of the computers are

I am having trouble finding an API that details functions calls and return values... The headers aren't exactly very clean either... I have found tons of examples, but I'm interested in error handling (return values). Am I approaching this wrong because I'm tearing my hair out trying to find something as basic as a function list for this well known library. NovaDenizen There is some documentation in libjpeg.txt . libjpeg is a very low-level, steep-learning-curve, old school c library. To use it effectively you need to be familiar with setjmp and longjmp, c structure layouts, function pointers,

1、首先，去wkhtmltopdf下载对应版本的Linux版本，地址如下： https://wkhtmltopdf.org/downloads.html 2、这里我服务器是centos 7，所以下载一个对应centos7的版本，下载得到一个rpm包。 3、接着放到服务器的某个目录底下，接着使用下面的命令： rpm -ivh wkhtmltox-0.12.5-1.centos7.x86_64.rpm 4、接着，不出意外的报错啦，竟然少了那么多依赖包： 5、缺少相关的依赖包，所以需要安装对应的依赖包（可以根据缺少的依赖包目录安装） （1）xorg-x11-fonts-75dpi依赖包： yum install xorg-x11-fonts-75dpi.noarch 遇到询问是否时，都恢复 y。 （2）xorg-x11-fonts-Type1依赖包： yum install xorg-x11-fonts-Type1.noarch 同样，遇到询问是否时，都恢复 y。 （3）libjpeg依赖包： yum install libjpeg （4）libXrender依赖包： yum install libXrender （5）libXext依赖包： yum install libXext （6）好像不用在安装其他的了，因为此时我再次执行命令： rpm -ivh wkhtmltox-0.12.5

I want to install PIL package on windows, its easy. but decoder jpeg not available. which packages are needed to download and installed befor PIL so it gets work? wtayyeb I found the solution. one has to use easy_install PIL instead of pip install PIP in Windows. easy_install finds local installation or installs the libjpeg from the source and connects it to PIL while pip cannot do that. Solution that worked for me (assuming you have the tools to compile packages, which depend on your python version, installed): Download precompiled binaries from http://gnuwin32.sourceforge.net/packages/jpeg

I haven't been able to find any resources on how to do this.. Anyone have any ideas or resources?! I've tried changing the ./configure options and I'm solving things one at a time but it seems like this method could take forever.. My current error is.. checking for jpeg_read_header in -ljpeg... no configure: error: Problem with libjpeg.(a|so). Please check config.log for more information. I'm running Snow Leopard. Any help would be great, Matt Mueller The current version (1.9) of MAMP / MAMP PRO includes PHP 5.3 and is available on the MAMP download page . I know this is an old question- but
