Qt、GDAL遥感影像显示

1、创建类

class GisBandMathProcess
	: public GisRasterProcess
{
	OGIS_DECLARE_MEMBERS(GisBandMathProcess);
public:

	GisBandMathProcess();

	~GisBandMathProcess();

	virtual QString processName() const;

	virtual OGis::ErrorStatus beginProcess();

	virtual OGis::ErrorStatus processData(ProcessData *pData) const;

	virtual OGis::ErrorStatus process(MatArray &desMat, const MatArray &srcMat, const MatArray &maskArray = MatArray());

private:

	void parseExperssion();

private:

	uint m_datasetIndex;
	QString m_exp, m_sPath;
	UIntArray m_bandIndexs;
	QStringList m_expStrings;

};

2、实现类

#include "StdAfx.h"

OGIS_CONS_DEFINE_MEMBERS_WORKER(GisBandMathProcess, GisRasterProcess)

GisBandMathProcess::GisBandMathProcess()
	: GisRasterProcess()
{

}
