hi, bei www.thecodeproject.com/bitmap/pictureshow.asp gibts eine "CPicture"-Klasse, die auch aus den Ressourcen beliebige formate (ok bmp, jpeg, gif) laden konnte. Dazu hab ich mir eine CStatic-Variante geschrieben:
| C++: |
#include "stdafx.h"
#include "ImageStatic.h"
IMPLEMENT_DYNAMIC(CImageStatic, CStatic)
BEGIN_MESSAGE_MAP(CImageStatic, CStatic)
ON_WM_CTLCOLOR_REFLECT()
ON_WM_DRAWITEM()
END_MESSAGE_MAP()
CImageStatic::CImageStatic() : m_Picture()
{
m_bFit = 0;
}
CImageStatic::~CImageStatic()
{
}
HBRUSH CImageStatic::CtlColor(CDC* pDC, UINT nCtlColor)
{
ModifyStyle(0,SS_OWNERDRAW);
return NULL;
}
void CImageStatic::SetBitmap(CString strBitmap)
{
m_Picture.FreePictureData();
m_Picture.Load(strBitmap);
}
void CImageStatic::SetBitmap(UINT ressource, LPCSTR restype)
{
m_Picture.FreePictureData();
m_Picture.Load(ressource, restype);
}
void CImageStatic::DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)
{
CDC dc;
dc.Attach(lpDrawItemStruct->hDC);
CDC *pDC = &dc;
CRect window;
GetClientRect(&window);
pDC->FillSolidRect(&window, RGB(255, 255, 255) );
int Width = 0;
int Height = 0;
int X = 1;
int Y = 1;
if(m_bFit)
{
if(m_Picture.m_Width > m_Picture.m_Height)
{
Width = window.Width();
Height = (int)(double)((double)window.Width() / (double)m_Picture.m_Width * (double)m_Picture.m_Height);
Y = (window.Height() - Height) / 2;
}
else
{
Width = (int)(double)((double)window.Height() / (double)m_Picture.m_Height * (double)m_Picture.m_Width);
Height = window.Height();
X = (window.Width() - Width) / 2;
}
}
else
{
Width = m_Picture.m_Width;
Height = m_Picture.m_Height;
X = (window.Width() - Width) / 2;
Y = (window.Height() - Height) / 2;
}
CRect rect( X, Y, X+Width, Y+Height);
m_Picture.Show(pDC, &rect);
}
void CImageStatic::OnDrawItem(int nIDCtl, LPDRAWITEMSTRUCT lpDrawItemStruct)
{
DrawItem(lpDrawItemStruct);
}
void CImageStatic::SetFit(BOOL bFit)
{
m_bFit = bFit;
}

| C++: |
#pragma once
#include "Picture.h"

wenn man m_bFit setzt, passt er das Bild an die Größe des Rahmens an.
