RE: [Dev-C++] displaying images during runtime

[Ramana K. <xr...@ho...>]

Following code works for me, don’t think I included any important headers…



<hInst> = the Instance of your program – you can use a pointer to get this 
from your main() function

<name> = is a char array containing the name in the resource of your picture 
e.g:

MYPICTURE BITMAP “C:/pic.bmp”



//this is the code, it is part of a class function def, sorry, I just copied 
out of my prog:

HBITMAP itsPicture;

ItsPicture = LoadBitmap(<hInst>,<name>);

void Room::Draw(HDC hdcWindow) const // just a function in my class

{

HDC hdcMemory;

hdcMemory  = CreateCompatibleDC(hdcWindow);



   RECT rc;                          //create a rectangle

   rc.left = 0;                      //filled with black

   rc.top = 0;                       //to act as a mask

   rc.right  = bm.bmWidth;

   rc.bottom = bm.bmHeight;

   FillRect(hdcWindow, &rc, (HBRUSH)GetStockObject((BLACK_BRUSH)));



SelectObject(hdcMemory, itsPicture);

BitBlt(hdcWindow, 0, 0, bm.bmWidth, bm.bmHeight, hdcMemory, 0, 0, SRCPAINT);



DeleteDC(hdcMemory);

}

Subject: [Dev-C++] displaying images during runtime



Hi there,

I like to display several images during runtime of my programm.

Charles Petzold uses in his book "Programming Windows" a function called 
BITMAPFILEHEADER* DibLoadImage( szName filename )
from DIBFILE.H to manage this.

#include "dibfile.h"
BITMAPFILEHEADER* pbmfh;

pbmfh = DibLoadImage( "myFile.bmp" );
...
SetDIBitsToDevice( pbmfh.cx, pbmfh.cy, ... );


DevC++ doesn't know anything about the header-file and it's functions :-(

PS:
LoadImage( ) won't work cause it returns a HANDLE instead of a 
BITMAPFILEHEADER.
