Hello, I am trying to read a bmp header this way:

typedef struct _SBMP3256
{
	BITMAPFILEHEADER bmfHeader;
	BITMAPINFOHEADER bmiHeader;
	RGBQUAD colors[256];
}BMP3256,*PBMP3256;

Open in new window


but this is what I get:

{biSize=9830400 biWidth=9830400 biHeight=65536 biPlanes = 32 ...

And the same code works in another program.

I found the solution, it is a compiler issue, it seems than the structure members alignement was not the same putting to 1 solve the problem.

Can do like that:
[code]#pragma pack(push, 1)

//structure(s)

#pragma pack(pop)[/code]
#pragma pack(push, 1)

//structure(s)

#pragma pack(pop)

Open in new window
