Detailed Description

Represents a simple visualization window.

View is a base class providing a simple OpenGL visualization window. Its task is to define basic functionality, such as the ability of the window to be responsive even when the main program thread is busy with calculations (ie., the windows are run in a background thread), to provide zooming and panning capabilities for use by the descendant classes, etc.

Member Function Documentation

void Hermes::Hermes2D::Views::View::save_numbered_screenshot ( const char *  format,
int  number,
bool  high_quality = false 
)

Like save_screenshot(), but forms the file name in printf-style using the 'number' parameter, e.g., format = "screen%03d.bmp" and number = 5 gives the file name "screen005.bmp".

Definition at line 918 of file view.cpp.

void Hermes::Hermes2D::Views::View::save_screenshot ( const char *  bmpname,
bool  high_quality = false 
)

Saves the current content of the window to a .BMP file. If 'high_quality' is true, an anti-aliased frame is rendered and saved.
