History:: 2011-07-02 Jeannie Backer - Moved this code from ObliqueCylindrical class to its own method here.

This method searches for extreme (min/max/discontinuity) coordinate values along the constBorder line between minBorder and maxBorder (that is, across latitudes/longitudes). This method locates the extrema by utilizing the findExtreme() method until the coordinate values converge. Then, extremeVal parameter is updated with this value before returning.

Discontinuities are stored in m_specialLatCases and m_specialLonCases so they may be checked again later, which creates significantly more accuracy in some cases.

Parameters

minBorder	Minimum latitude or longitude to search between.
maxBorder	Maximum latitude or longitude to search between.
extremeVal	The resulting global coordinate value (min or max value for x or y, depending on findMin and searchX) on the constBorder.
constBorder	The latitude or longitude that remains constant. The method will step along this border.
searchX	Indicates whether the method is searching for a min or max x-coordinate. If false the method searches for min or max y-coordinate.
searchLongitude	Indicates whether the method will search along a longitude. If true, constBorder is longitude and all other borders are latitudes. If false, the method searches a latitude (constBorder is a lat, other borders lons).
findMin	Indicates whether the method is looking for a minimum coordinate value. If false, the method is looking for a maximum value.

History:: 2011-07-02 Jeannie Backer - Moved this code from ObliqueCylindrical class to its own method here. Added condition to do-while loop for more precision. Replaced hard-coded TOLERANCE with 1/2 pixel resolution. (Defaults to 0.5)

Searches for extreme (min/max/discontinuity) coordinate values across latitudes/longitudes.

This method looks for these extrema along the constBorder between minBorder and maxBorder by stepping along constBorder (10 times) from the minBorder and maxBorder. Then, the range of this extreme value is recorded in minBorder and maxBorder and the coordinate values corresponding to these new borders are stored in minBorderX, minBorderY, maxBorderX and maxBorderY.

This function should be used by calling it repeatedly until minBorderX and minBorderY do not equal maxBorderX and maxBorderY, respectively. Discontinuities will cause the minBorderX, minBorderY, maxBorderX and maxBorderY to never converge. If minBorderX never comes close to maxBorderX or minBorderY never comes close to maxBorderY, then between minBorder and maxBorder is the value of the most extreme value. In this case, either the smaller or larger of the x or y values found will be correct, depending on the values of findMin and searchX.

Parameters

minBorder	Minimum latitude or longitude to search between. This value gets updated to a more precise range.
maxBorder	Maximum latitude or longitude to search between. This value gets updated to a more precise range.
minBorderX	The x-value corresponding to the lower resultant minBorder and the constBorder, which is more accurate when nearly equal to maxBorderX.
minBorderY	The y-value corresponding to the lower resultant minBorder and the constBorder, which is more accurate when nearly equal to maxBorderY.
maxBorderX	The x-value corresponding to the higher resultant maxBorder and the constBorder, which is more accurate when nearly equal to minBorderX.
maxBorderY	The y-value corresponding to the higher resultant maxBorder and the constBorder, which is more accurate when nearly equal to minBorderY.
constBorder	The latitude or longitude that remains constant. The method will step along this border.
searchX	Indicates whether the method is searching for a min or max x-coordinate. If false the method searches for min or max y-coordinate.
searchLongitude	Indicates whether the method will search along a longitude. If true, constBorder is longitude and all other borders are latitudes. If false, the method searches a latitude (constBorder is a lat, other borders lons).
findMin	Indicates whether the method is looking for a minimum coordinate value. If false, the method is looking for a maximum value.

This function sets the ground for the given border values. It calls the SetGround(lat, lon) method with the appropriate lat/lon values, depending on whether variableIsLat is true.

This method is used by doSearch and findExtreme in order to set the ground correctly each time.

Parameters

variableBorder	The latitude or longitude that is variable in the search methods.
constBorder	The latitude or longitude that is constant in the search methods.
variableIsLat	Indicates whether variableBorder is the latittude value and constBorder is the longitude value. If false, variableBorder is the longitude value and constBorder is the latitude value.

◆ SetWorld()

bool Isis::Projection::SetWorld	(	const double	worldX,
		const double	worldY
	)

inherited

This method is used to set a world coordinate.

A world coordinate is a different coordinate type that has a one-to-one mapping to the projection coordinate system. For example, mapping pixel samples and lines to projection x's and y's. The Set forces an attempted calculation of the corresponding latitude/longitude position. This may or may not be successful and a status is returned as such. Note that is only applies if the Projection object was given an WorldMapper object during construction. If an WorldMapper was not supplied then SetWorld operates exactly the same as SetCoordinate (impling that world coordinate and projection coordinate are identical).

Parameters

worldX	World X coordinate in units that are specified by the WorldMapper object (e.g., pixels, millimeters, etc)
worldY	World Y coordinate in units that are specified by the WorldMapper object (e.g., pixels, millimeters, etc)

Returns: bool Indicates whether the method was successful.

◆ SetWorldMapper()

void Isis::Projection::SetWorldMapper ( WorldMapper * mapper )

inherited

If desired the programmer can use this method to set a world mapper to be used in the SetWorld, WorldX, and WorldY methods.

Mappers typically transform a projection coordinate (x/y) into the desired working coordinate system, for example, cube pixels or inches on a piece of paper. They transform in both directions (world to projection and projection to world). This allows for conversions from line/sample to latitude/longitude and vice versa. This projection will take ownership of the WorldMapper pointer.

Parameters

mapper Pointer to the mapper

◆ XYRange()

bool Isis::RingCylindrical::XYRange	(	double &	minX,
		double &	maxX,

		double &	maxY
	)

virtual

This method is used to determine the x/y range which completely covers the area of interest specified by the radius/lon range.

The radius/longitude range may be obtained from the labels. This method should not be used if HasGroundRange is false. The purpose of this method is to return the x/y range so it can be used to compute how large a map may need to be. For example, how big a piece of paper is needed or how large of an image needs to be created. This is method and therefore must be written by the derived class (e.g., RingCylindrical). The method may fail as indicated by its return value.

Parameters

&minX	Reference to the address where the minimum x coordinate value will be written. The Minimum x projection coordinate calculated by this method covers the radius/longitude range specified in the labels.
&maxX	Reference to the address where the maximum x coordinate value will be written. The Maximum x projection coordinate calculated by this method covers the radius/longitude range specified in the labels.
&minY	Reference to the address where the minimum y coordinate value will be written. The Minimum y projection coordinate calculated by this method covers the radius/longitude range specified in the labels.
&maxY	Reference to the address where the maximum y coordinate value will be written. The Maximum y projection coordinate calculated by this method covers the radius/longitude range specified in the labels.

Returns: bool Indicates whether the method was able to determine the X/Y Range of the projection. If yes, minX, maxX, minY, maxY will be set with these values.
