Member Function Documentation

◆ GetImage() [1/2]

unsigned char * VAPoR::GeoImageGeoTiff::GetImage	(	size_t	ts,
		const double	pcsExtentsReq[4],
		string	proj4StringReq,
		size_t	maxWidthReq,
		size_t	maxHeightReq,
		double	pcsExtentsImg[4],
		double	geoCornersImg[8],
		string &	proj4StringImg,
		size_t &	width,
		size_t &	height
	)

virtual

Fetch a georeferenced image

Parameters

[in]	ts	time step
[in]	pcsExtentsReq	A four-element array containing the extents (llx, lly, urx, ury) of the requested region in Projected Coordinates.
[in]	proj4StringReq	The Proj4 string that maps lat-long coordinates into the PCS coordinates used in `pcsExtentsReq`.
[in]	maxWidthReq	The requested maximum width in pixels of the returned image
[in]	maxHeightReq	The requested maximum height in pixels of the returned image
[out]	pcsExtentsImg	A four-element array containing the extents (llx, lly, urx, ury) of the returned image map in Projected Coordinates of the image.
[out]	geoCornersImg	An eight-element array containing the corner points (llx, lly, ulx, uly, urx, ury, lrx, lry) of the returned image map in Geographic coordinates
[out]	width	The actual width in pixels of the returned image
[out]	height	The actual height in pixels of the returned image

Return values

image Upon success at 2D texture with n channels (See GeoImage::GeoImage()) is returned. Memory for the returned image is managed by the class, and should not be freed.

Implements VAPoR::GeoImage.

◆ GetImage() [2/2]

unsigned char * VAPoR::GeoImageGeoTiff::GetImage	(	size_t	ts,
		size_t &	width,
		size_t &	height
	)

virtual

Fetch a non-georeferenced image

Return an image without any geo-referencing information.

Parameters

[in]	ts	time step of image
[out]	width	Width in pixels of returned image
[out]	height	Height in pixels of returned image

Return values

image Upon success at 2D texture with n channels (See GeoImage::GeoImage()) is returned. Memory for the returned image is managed by the class, and should not be freed.

Implements VAPoR::GeoImage.

◆ Initialize()

int VAPoR::GeoImageGeoTiff::Initialize	(	string	path,
		vector< double >	times
	)
