load gif into program
hey, i was wondering how easy it would be to load a gif into a program similarly to how you can load in a bitmap. that way at runtime, you dont have to give the user the program and a bunch of pictures. you can just give them the program and they can run with it.

i've got it downloaded but i haven't been able to find any helping reading material stating what function(s) i need to use to load the gifs.
however, i did download a batch image editor and converted all of the gifs to bmps as well as resizing them, so now the only point would be for knowledge and to make my programs size smaller. although, compressed its only 74KB lol

Look at the Image class. ie Image::FromFile()

two questions, just to be sure: this will work for win32 correct? because i dont do MFC..
would i still declare the control as SS_BITMAP? and the pretend that the file is a bitmap, even though its a gif? i.e. would i still send a message to change the image using the IMAGE_BITMAP for the WPARAM, etc.?
also - i downloaded the platform sdk from M$ from here: http://www.microsoft.com/downloads/d...displaylang=en
and when i try to compile in Dev-C++ i'm getting a ........TON of errors:

/*------ Edit ------*/
after including the lib & include paths in VC++ 2005 EE (i HAVE included such paths in Dev-C++ also) it seems to have no problems with the headers / libs / etc. it just doesn't like my code, lol which makes sense b/c i dont know what i'm doing :] but this is the code i'm trying:
Code:

so is there a tutorial somewhere on using the function? MSDN wasn't much help for me here..

That's probably because GDI+ is a C++ only. Why they've done that I don't know, but either way it'll never work in your C file.

The cheaters' way to do it is:-
Code:
LPPICTURE LoadPicture(char *szFilename)
{
   LPPICTURE lpPicture;

   // This is an OLE function, filename must be in Unicode
#ifndef UNICODE
   unsigned short wzFilename[MAX_PATH];
   MultiByteToWideChar(GetACP(), MB_PRECOMPOSED, szFilename, -1, wzFilename, MAX_PATH);
#else
   char *wzFilename;
   wzFilename = szFilename;
#endif
   if (OleLoadPicturePath(wzFilename, NULL, 0, 0, &IID_IPicture, (void **)&lpPicture) != S_OK)
      return NULL;

   return lpPicture;
}
And when you want to show it on a DC:-
Code:
int iHiWidth, iHiHeight; // gives you size in HIMETRICs
BITMAP bmp; // pixel size in here
HBITMAP hbmp;

lpPicture->lpVtbl->get_Width(lpPicture, &iHiWidth);
lpPicture->lpVtbl->get_Height(lpPicture, &iHiHeight);
lpPicture->lpVtbl->get_Handle(lpPicture, (OLE_HANDLE *)&hbmp);
GetObject(hbmp, sizeof(BITMAP), &bmp);
lpPicture->lpVtbl->Render(lpPicture, hdc, 0, 0, bmp.bmWidth, bmp.bmHeight, 0, iHiHeight, iHiWidth, -iHiHeight, NULL);
When you're finished with it, remember to:-
Code:
lpPicture->lpVtbl->Release(lpPicture);
Depending on which version of Windows is being used, you may also need to call CoInitialize().

Smurf's code has some errors in the UNICODE handling. The strings should be declared as wide strings.

Here is my code to load pictures. It uses pretty much the same technique as Smurf's, except I use OleLoadPicture instead of OleLoadPicturePath. This was because in my project I had to manipulate the buffer before I rendered it. In my code the picture is double buffered so it doesn't flicker, and it automatically resizes to fill the window that it is being rendered on. It should compile as it is.
Code:
#include <windows.h>
#include <tchar.h>
#include <ocidl.h>
#include <olectl.h>
#define HIMETRIC_PER_INCH 2540

typedef struct tagPictureData
{
	IPicture	*IPic;
	SIZE		sizeInPixels;
	SIZE		sizeInHiMetric;

} PictureData;

	PictureData	*picData;
	SIZE		sizeInHiMetric, sizeInPixels;
	

	hdc = GetDC(NULL);

	/* Get the number of pixels on the screen */
	nPixelsPerInchX = GetDeviceCaps(hdc, LOGPIXELSX);
	nPixelsPerInchY = GetDeviceCaps(hdc, LOGPIXELSY);

	ReleaseDC(NULL, hdc);


	hFile = CreateFile(name,GENERIC_READ,0,NULL,OPEN_EXISTING,0,NULL);

mm..i may be doing something wrong, but i saved it as a new win32 proj, C++ in dev-cpp n i got this:

My code was for C, you are compiling it as C++.

So instead of
x->lpVtbl->foo(x,...);
you would do:
x->foo(...);

For example:
Code:
pStream->lpVtbl->Release(pStream);
would be changed to
Code:
pStream->Release();
Quote:
LoadPic.cpp:123: error: invalid conversion from `void*' to `PictureData*'
C++ requires you to explicitly cast this.

I think that's all you need to change.

well it was previously stated that GDI+ was strictly C++, so i figured any code posted thereafter was going to be C++. personally I like C better than C++ :] but thats def. good to know, lol



bah...ich verstehe nicht. so by changing it to a C file and adding it to a dif. C project, i got more errors :[ :[

Anytime you get errors that begin with "undefined reference to X", those are linker errors. What it means is that you are calling a function, or using a variable, but your linker can't find the function implementation anywhere. 9 times out of 10 this means you need to link to some external library.

If you do a search for CreateStreamOnHGlobal, you see in the documentation that is needs to be linked to Ole32.dll. A similar search on OleLoadPicture gives us olepro32.dll.

Sorry did not realise you were using C.

I have only used GDI+ in C++. MSDN states it is for C/C++ so I did not think to mention that.

You could try calling the image functions through the flat file Gdiplusflat.h (ensure Gdiplus.dll is linked) and try to bypass the C++ wrapper. This is not recomended though.

Possibly worth a look, though is not in C but a mix of C and C++ using .cpp files.

How so? I thought it worked quite well: if UNICODE isn't defined, convert the ANSI szFilename to wide wzFilename. Otherwise, szFilename will automatically be wide (sizeof(char) == 2) and nothing else is needed.

How do you figure that szFilename will be a wide char string? Considering it's declared as a char*, that is impossible.
If UNICODE is defined, you get:
Code:
char *wzFilename;  /* wzFilename is a regular char array */
wzFilename = szFilename; /* this does nothing except assign the char array to another pointer */
/* Here you get an error trying to pass a char* when the function wants an unsigned short* */
if (OleLoadPicturePath(wzFilename, NULL, 0, 0, &IID_IPicture, (void **)&lpPicture) != S_OK)
      return NULL;
