MAPPING MODE

Function to set Map Mode: virtual intSetMapMode(intnMapMode);

• MM_ANISOTROPIC   Logical units are converted to arbitrary units with arbitrarily scaled axes. Setting the mapping mode to MM_ANISOTROPIC does not change the current window or viewport settings. To change the units, orientation, and scaling, call the SetWindowExt and SetViewportExt member functions.
• MM_HIENGLISH: 0.001 inch. Positive x: right; positive y: up.
• MM_HIMETRIC:  0.01 millimeter. Positive x: right; positive y: up.
• MM_ISOTROPIC   Logical units are converted to arbitrary units with equally scaled axes; that is, 1 unit along the x-axis is equal to 1 unit along the y-axis. Use theSetWindowExt and SetViewportExt member functions to specify the desired units and the orientation of the axes. GDI makes adjustments as necessary to ensure that the x and y units remain the same size.
• MM_LOENGLISH: 0.01 inch. Positive x: right; positive y: up.
• MM_LOMETRIC: 0.1 millimeter. Positive x: right; positive y: up.
• MM_TEXT: 1 device pixel. Positive x: right; positive y: down.
• MM_TWIPS: 1/20 of a point. (Because a point is 1/72 inch, a twip is 1/1440 inch.) Positive x: right; positive y: up.
