MFC - GDI

Windows provides a variety of drawing tools to use in device contexts. It provides pens to draw pnes, brushes to fill interiors, and fonts to draw text. MFC provides graphic-object classes equivalent to the drawing tools in Windows.

Drawing

A device context is a Windows data structure containing information about the drawing attributes of a device such as a display or a printer. All drawing calls are made through a device-context object, which encapsulates the Windows APIs for drawing pnes, shapes, and text.

Device contexts allow device-independent drawing in Windows. Device contexts can be used to draw to the screen, to the printer, or to a metafile.

CDC is the most fundamental class to draw in MFC. The CDC object provides member functions to perform the basic drawing steps, as well as members for working with a display context associated with the cpent area of a window.

Given below is the pst of methods in CDC class.

2	AbortPath Closes and discards any paths in the device context.
3	AddMetaFileComment Copies the comment from a buffer into a specified enhanced-format metafile.
4	AlphaBlend Displays bitmaps that have transparent or semitransparent pixels.
5	AngleArc Draws a pne segment and an arc, and moves the current position to the ending point of the arc.

Lines

Step 1 − Let us look into a simple example by creating a new MFC based single document project with MFCGDIDemo name.

Step 2 − Once the project is created, go the Solution Explorer and double cpck on the MFCGDIDemoView.cpp file under the Source Files folder.

Step 3 − Draw the pne as shown below in CMFCGDIDemoView::OnDraw() method.

void CMFCGDIDemoView::OnDraw(CDC* pDC) {
   pDC->MoveTo(95, 125);
   pDC->LineTo(230, 125);
   CMFCGDIDemoDoc* pDoc = GetDocument();
   ASSERT_VALID(pDoc);
   if (!pDoc)
      return;

   // TODO: add draw code for native data here
}

Step 4 − Run this apppcation. You will see the following output.

Step 5 − The CDC::MoveTo() method is used to set the starting position of a pne.

When using LineTo(), the program starts from the MoveTo() point to the LineTo() end.

After LineTo() when you do not call MoveTo(), and call again LineTo() with other point value, the program will draw a pne from the previous LineTo() to the new LineTo() point.

Step 6 − To draw different pnes, you can use this property as shown in the following code.

void CMFCGDIDemoView::OnDraw(CDC* pDC) { 
   pDC->MoveTo(95, 125);
   pDC->LineTo(230, 125);
   pDC->LineTo(230, 225);
   pDC->LineTo(95, 325);
   CMFCGDIDemoDoc* pDoc = GetDocument();
   ASSERT_VALID(pDoc);
   if (!pDoc)
      return;

   // TODO: add draw code for native data here 
}

Step 7 − Run this apppcation. You will see the following output.

Polypnes

A polypne is a series of connected pnes. The pnes are stored in an array of POINT or CPoint values. To draw a polypne, you use the CDC::Polypne() method. To draw a polypne, at least two points are required. If you define more than two points, each pne after the first would be drawn from the previous point to the next point until all points have been included.

Step 1 − Let us look into a simple example.

void CMFCGDIDemoView::OnDraw(CDC* pDC) {
   CPoint Pt[7];
   Pt[0] = CPoint(20, 150);
   Pt[1] = CPoint(180, 150);
   Pt[2] = CPoint(180, 20);
   pDC−Polypne(Pt, 3);
   
   CMFCGDIDemoDoc* pDoc = GetDocument();
   ASSERT_VALID(pDoc);
   if (!pDoc)
      return;

   // TODO: add draw code for native data here
}

Step 2 − When you run this apppcation, you will see the following output.

Rectangles

A rectangle is a geometric figure made of four sides that compose four right angles. Like the pne, to draw a rectangle, you must define where it starts and where it ends. To draw a rectangle, you can use the CDC::Rectangle() method.

Step 1 − Let us look into a simple example.

void CMFCGDIDemoView::OnDraw(CDC* pDC) {
   pDC->Rectangle(15, 15, 250, 160);
   
   CMFCGDIDemoDoc* pDoc = GetDocument();
   ASSERT_VALID(pDoc);
   if (!pDoc)
      return;

   // TODO: add draw code for native data here
}

Step 2 − When you run this apppcation, you will see the following output.

Squares

A square is a geometric figure made of four sides that compose four right angles, but each side must be equal in length.

Let us look into a simple example.

void CMFCGDIDemoView::OnDraw(CDC* pDC) {
   pDC->Rectangle(15, 15, 250, 250);
   
   CMFCGDIDemoDoc* pDoc = GetDocument();
   ASSERT_VALID(pDoc);
   if (!pDoc)
      return;

   // TODO: add draw code for native data here
}

When you run this apppcation, you will see the following output.

Pies

A pie is a fraction of an elppse depmited by two pnes that span from the center of the elppse to one side each. To draw a pie, you can use the CDC::Pie() method as shown below −

BOOL Pie(int x1, int y1, int x2, int y2, int x3, int y3, int x4, int y4);

The (x1, y1) point determines the upper-left corner of the rectangle in which the elppse that represents the pie fits. The (x2, y2) point is the bottom-right corner of the rectangle.

The (x3, y3) point specifies the starting corner of the pie in a default counterclockwise direction.

The (x4, y4) point species the end point of the pie.

Let us look into a simple example.

void CMFCGDIDemoView::OnDraw(CDC* pDC) {
   pDC->Pie(40, 20, 226, 144, 155, 32, 202, 115);
   
   CMFCGDIDemoDoc* pDoc = GetDocument();
   ASSERT_VALID(pDoc);
   if (!pDoc)
      return;

   // TODO: add draw code for native data here
}

Step 2 − When you run this apppcation, you will see the following output.

Arcs

An arc is a portion or segment of an elppse, meaning an arc is a non-complete elppse. To draw an arc, you can use the CDC::Arc() method.

BOOL Arc(int x1, int y1, int x2, int y2, int x3, int y3, int x4, int y4);

The CDC class is equipped with the SetArcDirection() method.

Here is the syntax −

int SetArcDirection(int nArcDirection)

Sr.No.	Value & Orientation
1	AD_CLOCKWISE The figure is drawn clockwise
2	AD_COUNTERCLOCKWISE The figure is drawn counterclockwise

Sr.No.

Value & Orientation

AD_CLOCKWISE

The figure is drawn clockwise

AD_COUNTERCLOCKWISE

The figure is drawn counterclockwise

Step 1 − Let us look into a simple example.

void CMFCGDIDemoView::OnDraw(CDC* pDC) {
   pDC->SetArcDirection(AD_COUNTERCLOCKWISE);
   pDC->Arc(20, 20, 226, 144, 202, 115, 105, 32);
   
   CMFCGDIDemoDoc* pDoc = GetDocument();
   ASSERT_VALID(pDoc);
   if (!pDoc)
      return;

   // TODO: add draw code for native data here
}

Step 2 − When you run this apppcation, you will see the following output.

Chords

The arcs we have drawn so far are considered open figures because they are made of a pne that has a beginning and an end (unpke a circle or a rectangle that do not). A chord is an arc whose two ends are connected by a straight pne.

To draw a chord, you can use the CDC::Chord() method.

BOOL Chord(int x1, int y1, int x2, int y2, int x3, int y3, int x4, int y4);

Let us look into a simple example.

void CMFCGDIDemoView::OnDraw(CDC* pDC) {
   pDC->SetArcDirection(AD_CLOCKWISE);
   pDC->Chord(20, 20, 226, 144, 202, 115, 105, 32);
   
   CMFCGDIDemoDoc* pDoc = GetDocument();
   ASSERT_VALID(pDoc);
   if (!pDoc)
      return;

   // TODO: add draw code for native data here
}

When you run the above apppcation, you will see the following output.

The arc direction in this example is set clockwise.

Colors

The color is one the most fundamental objects that enhances the aesthetic appearance of an object. The color is a non-spatial object that is added to an object to modify some of its visual aspects. The MFC pbrary, combined with the Win32 API, provides various actions you can use to take advantage of the various aspects of colors.

The RGB macro behaves pke a function and allows you to pass three numeric values separated by a comma. Each value must be between 0 and 255 as shown in the following code.

void CMFCGDIDemoView::OnDraw(CDC* pDC) {
   COLORREF color = RGB(239, 15, 225);
}

Let us look into a simple example.

void CMFCGDIDemoView::OnDraw(CDC* pDC) {
   COLORREF color = RGB(239, 15, 225);
   pDC->SetTextColor(color);
   pDC->TextOut(100, 80, L"MFC GDI Tutorial", 16);
   
   CMFCGDIDemoDoc* pDoc = GetDocument();
   ASSERT_VALID(pDoc);
   if (!pDoc)
      return;

   // TODO: add draw code for native data here
}

When you run this apppcation, you will see the following output.
