Summary

Sets the physical (pixel) bounds of the specified SVG document manually.

Syntax

#include "l_bitmap.h"

L_LTSVG_API L_INT L_SvgSetBounds(flatDocHandle, bounds)

Parameters

L_SvgNodeHandle flatDocHandle

The SVG document handle for which the bounds should be updated.

const L_SvgBounds* bounds

Pointer to a structure containing the bounds to use.

Returns

Value	Meaning
SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

Support for SVG is only available in the Document and Medical Imaging toolkits.

For more information on flat SVG documents and bounds and resolution, refer to SVG Size, Bounds and Flat.

Platforms

Win32, x64, Linux.

Example

This example loads a PDF file as SVG and then gets and sets the physical (pixel) bounds and resolution of the document
