Syntax
// Java public TGIS_RendererAbstractCache PrepareBitmapCache( int[] _bmp, TGIS_Extent _extent, TPoint _size, int _serial, TGIS_BitmapFormat _format, TGIS_BitmapLinesOrder _order );
// Oxygene public function PrepareBitmapCache( _bmp : TGIS_Pixels; _extent : TGIS_Extent; _size : TPoint; _serial : Integer; _format : TGIS_BitmapFormat; _order : TGIS_BitmapLinesOrder ) : TGIS_RendererAbstractCache; virtual;
Parameters
| Name | Type | Description |
|---|---|---|
| _bmp | int[] TGIS_Pixels | array of bitmap pixels |
| _extent | TGIS_Extent | extent of _bmp |
| _size | TPoint | width/height of _bmp (in pixels) |
| _serial | int Integer | serial number of layer.Params; to keep track of layer rendering parameters change |
| _format | TGIS_BitmapFormat | pixel format of _bmp array |
