Tugas 2

1. Tambahan program pada button untuk melakukan load gambar:

void CPrak11_1Dlg::OnButton1()
{
// TODO: Add your control notification handler code here
static char BASED_CODE szFilter[]="Bitmap Files (*.bmp)|*.bmp||";
CFileDialog m_ldFile(TRUE, "*.bmp", name,
OFN_HIDEREADONLY|OFN_OVERWRITEPROMPT, szFilter);
if(m_ldFile.DoModal()==IDOK)
{
name=m_ldFile.GetPathName();
}
CDC* pDC = m_pic1.GetDC();// mengarah kontrol picture
CDC dcMem; //mengarahkan obyek yg sdh dipilih pd bitmap
CRect rect;//kotak di picture
BITMAP bm;//mendefinisikan fungsi2 yg ada d bitmap
HBITMAP hBitmap=(HBITMAP)::LoadImage(AfxGetInstanceHandle(),
name ,IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE|LR_CREATEDIBSECTION);
if(hBitmap)
{
if(m_bmpBitmap.DeleteObject())
m_bmpBitmap.Detach();
m_bmpBitmap.Attach(hBitmap);
}
m_pic1.GetClientRect(rect);//
m_bmpBitmap.GetBitmap(&bm);//
dcMem.CreateCompatibleDC(pDC);
//pDC->MoveTo(10,190);
//pDC->LineTo(300,190);
dcMem.SelectObject(&m_bmpBitmap);
pDC->StretchBlt(0,0,rect.Width(),rect.Height(),&dcMem,
0,0,bm.bmWidth,bm.bmHeight,SRCCOPY);
}

2. Tambahan program pada button 2 yang menampilkan warna merah:
void CPrak11_1Dlg::OnButton2()
{
// TODO: Add your control notification handler code here
int i,j,red,green,blue;
long int warna;
CDC* pDC = m_pic1.GetDC();// mengarah kontrol picture
CDC dcMem1; //mengarahkan obyek yg sdh dipilih pd bitmap
CRect rect;//kotak di picture
BITMAP bm;//mendefinisikan fungsi2 yg ada d bitmap
int hr[256];
HBITMAP hBitmap=(HBITMAP)::LoadImage(AfxGetInstanceHandle(),
name,IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE|LR_CREATEDIBSECTION);
if(hBitmap)
{
if(m_bmpBitmap.DeleteObject())
m_bmpBitmap.Detach();
m_bmpBitmap.Attach(hBitmap);
}
m_pic1.GetClientRect(rect);//
m_bmpBitmap.GetBitmap(&bm);//

dcMem1.CreateCompatibleDC(pDC);
dcMem1.SelectObject(&m_bmpBitmap);

for(i=0;i<256;i++)
hr[i]=0;
for(i=0;i
for(j=0;j
{
warna=dcMem1.GetPixel(j,i);
WarnaToRGB(warna,&red,&green,&blue);
hr[red]=hr[red]+1;
}
float hmax=hr[0];
for(i=1;i<256;i++)
{
if(hr[i]>hmax)
hmax=hr[i];
}
for(i=0;i<256;i++)
hr[i]=120*hr[i]/hmax;

CDC* pDC1=m_pic2.GetDC();
pDC1->MoveTo(0,100);
pDC1->LineTo(550,100); //sb x
pDC1->MoveTo(0,100-(int)hr[0]); //ttk h[0]
for(i=1;i<256;i++)
{
pDC1->MoveTo(i*2,100);
pDC1->LineTo(i*2,100-(int)hr[i]);
}
}

3. Merubah data pixel ke RGB:

void WarnaToRGB(long int warna,int *Red, int *Green, int *Blue)
{
*Red = warna & 0x000000FF;
*Green = (warna & 0x0000FF00) >> 8;
*Blue = (warna & 0x00FF0000) >> 16;
}

4. Mengubah RGB ke data pixel:

long int RGBToWarna(int Red, int Green, int Blue)
{
return(Red+(Green<<8)+(Blue<<16));
}

Laporan Resmi2

semua ketidaksempurnaan pada gambar di atas, yaitu adanya gambar lain yang masuk pada tampilan warna blue, namun untuk hasil output pada kombinasi warna RGB masing-masing bernilai 255, 255, 255 adalah warna putih hal ini sudah termasuk memenuhi kriteria.
Pada percobaan kedua memahami maksud dari percobaan ini. Yaitu bagaimana kita memproses gambar dengan mengambil warna RGB (red,green,blue)
Tampilan awal adalah pada saat penekanan tombol merah warna yang keluar adalah merah. Begitu juga sama halnya untuk warna hijau dan biru. dan menamplikan semua warna langsung yaitu Red, Green, dan Blue
