| CT_EXPORT void COpenGlGraphicsContext::Clear | ( | ) | [virtual] |
Clear the drawing area to transparent black. If colors are not stored set all pixels to zero intensity. If transparency levels are not stored set all pixels to black.
Implements CartoType::CGraphicsContext.
| CT_EXPORT TResult COpenGlGraphicsContext::DrawBitmap | ( | const TBitmap & | aBitmap, |
| const TPoint & | aTopLeft | ||
| ) | [virtual] |
Draw a bitmap. If the bitmap has no color information use the current color. Combine any alpha information from the bitmap with the current alpha level. The coordinates are whole pixels.
Implements CartoType::CGraphicsContext.
| CT_EXPORT TResult COpenGlGraphicsContext::DrawShape | ( | const MPath & | aPath, |
| uint32 | aFlags | ||
| ) | [virtual] |
Draw a filled shape in the current color.
Implements CartoType::CGraphicsContext.
| CT_EXPORT void COpenGlGraphicsContext::OnViewResize | ( | int32 | aWidth, |
| int32 | aHeight | ||
| ) | [virtual] |
Call this when the native window's size is set for the first time or changed.
Reimplemented from CartoType::CGraphicsContext.
| CT_EXPORT void COpenGlGraphicsContext::Sync | ( | ) | [virtual] |
Synchronize the private graphics state to take account of any changes in iChangeFlags.
Implements CartoType::CGraphicsContext.
