Checks locked pixels.
// Delphi protected function findProperPixelLock( const _ext : TGIS_Extent; const _cs : TGIS_CSCoordinateSystem; const _pixelsize : Double; const _band : Integer; const _writable : Boolean ) : Integer;
// C++ Builder protected: int findProperPixelLock( TGIS_Extent* const _ext, TGIS_CSCoordinateSystem* const _cs, const double _pixelsize, const int _band, const bool _writable );
| Name | Type | Description |
|---|---|---|
| _ext | TGIS_Extent | area to be locked; if bigger then layer extent then will be truncated to layer extent |
| _cs | TGIS_CSCoordinateSystem | coordinate system of _cs; if nil then same as layer CS |
| _pixelsize | Double | minimum requested size of image pixel; by providing 0 a maximum possible resolution will be used |
| _band | Integer | band number if specific band is locked or 0 |
| _writable | Boolean | true when searching for writable lock |
| Type | Description |
|---|---|
| Integer | Index for oLayerList (-1 if not find). |
