Detailed Description

This class extends osg::Image with an interface to support vtdata's Bitmap operations and use vtdata's vtDIB. It is useful for creating images in memory.

If you are going to use OSG to load an image from disk, you must use osg::Image instead, which can be loaded with osgDB::readImageFile.

A common use for an image is as a texture map for a textured material, by passing it to vtMaterial::SetTexture().

Member Function Documentation

bool vtImage::GetColorSolid	(	const DPoint2 &	p,
		RGBi &	rgb,
		double	dRes = `0.0`
	)

Sample image color at a given point, assuming that the pixels are solid.

Returns: true if a value was found, false if the point is outside the extent or (if the option is enabled) the value was 'nodata'.

bool vtImage::GetMultiSample	(	const DPoint2 &	p,
		const DLine2 &	offsets,
		RGBi &	rgb,
		double	dRes = `0.0`
	)

Get image color by sampling several points and averaging them. The area to test is given by center and offsets, use MakeSampleOffsets() to make a set of N x N offsets.

bool vtImage::ReprojectExtents ( const vtProjection & proj_new)

Reprojects an image by converting just the extents to a new projection.

This is much faster than creating a new grid and reprojecting every heixel, but it only produces correct results when the difference between the projections is only a horizontal shift. For example, this occurs when the only difference between the old and new projection is choice of Datum.

Parameters

proj_new The new projection to convert to.

Returns: True if successful.

bool vtImage::WriteJPEG	(	const char *	fname,
		int	quality = `99`,
		bool	progress_callbackint = `NULL`
	)

Write this image to a JPEG file. Quality setting is the same as libjpeg, in the range of 0..100. 99 is a typically useful quality setting.
