How to use CxImage

[Cooker]

Hi,
I download the CxImage project from web(http://www.xdp.it/projects.htm).
I compile the jpeg projet and CxImage project to get the jpeg.lib and cximage.lib.
I include the all header file in CxImage project , jpeg.lib and cximage.lib.
Write the following source:

#include <windows.h>
#include "ximage.h"
#pragma comment(lib,"CxImage.lib")
#pragma comment(lib,"jpeg.lib")


int WINAPI WinMain(HINSTANCE,HINSTANCE,LPSTR,int)
{
CxImage image;

// bmp -> jpg
image.Load("C:\\image.bmp", CXIMAGE_FORMAT_BMP);
if (image.IsValid())
{
if(!image.IsGrayScale()) image.IncreaseBpp(24);
image.SetJpegQuality(70);
image.Save("C:\\image.jpg",CXIMAGE_FORMAT_JPG);
}

return 0;
}

and get the error

c:\program files\microsoft visual studio\myprojects\cximage\xfile.h(52) : error C2061: syntax error : identifier 'CxFile'
c:\program files\microsoft visual studio\myprojects\cximage\xfile.h(52) : error C2059: syntax error : ';'

Error executing cl.exe.

main.obj - 11 error(s), 0 warning(s)

I would like to conversion between bmp and jpeg.
What shall I do to complete the project???
Thank you! :)

Hi,

you have to rename your "main.c" to "main.cpp" because the C-Compiler cannot handle classes (which are used in the CxImage library). You must use C++.

After doing that you'll get a lot of linker errors .... Don't ask me how to fix them :-(

Hope it helps

I think you should go through the followings.

Mixed-Language Programming: Overview (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vccore98/html/_core_mixed.2d.language_programming.3a_.overview.asp)
Programming with Mixed Languages (http://h18009.www1.hp.com/fortran/docs/vf-html/pg/pgwpmixl.htm)

Surely google will give you much more.
