Summary

Gets the current viewport width and height used when loading 3D file formats.

Syntax

#include "l_bitmap.h"

L_LTFIL_API L_INT L_2DGetViewport(pnWidth, pnHeight)

Parameters

L_INT* pnWidth

Pointer to a variable to be updated with the current viewport width in pixels.

L_INT* pnHeight

Pointer to a variable to be updated with the current viewport height in pixels.

Returns

Comments

To set the viewport width and height in pixels, use L_2DSetViewport.

When working with Vector files, you can use the Vector features, available in selected products, or you can use the Raster C API. If you use the Main C API for loading, using the standard loading functions, you can modify the view port and view mode using the following functions:

• L_2DGetViewMode
• L_2DSetViewMode
• L_2DGetViewport
• L_2DSetViewport

This function may be used with the following Vector file formats: DXF, DWG, WMF, EMF, PCT, CGM, DRW, PLT, TIF (with a DXF saved internally) and Intergraph Vector. For more information on these file formats and their availability, refer to LEADTOOLS Vector Formats.

Required DLLs and Libraries

• LTKRN
• LTFIL
• For a listing of the exact DLLs and Libraries needed, based on the toolkit version, refer to Files To Be Included With Your Application.

Platforms
