Graphic Objects

The pen, brush, bitmap, palette, region, and path associated with a device context are referred to as the device context's graphic objects. Following are the attributes associated with each of these objects.

Graphic object	Associated attributes
Bitmap	Size, in bytes; dimensions, in pixels; color-format; compression scheme; and so on
Brush	Style, color, pattern, and origin
Palette	Colors and size (or number of colors)
Font	Typeface name, width, height, weight, character set, and so on
Path	Shape
Pen	Style, width, and color
Region	Location and dimensions

When an application creates a device context, Windows automatically stores a set of default objects in it. (There is no default bitmap or path.) An application can examine the attributes of the default objects by calling the GetCurrentObject and GetObject functions. The application can change these defaults by creating a new object and selecting it into the device context. An object is selected into a device context by calling the SelectObject function.

Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More »
