Description

Get the sparkline into the PictureHolder

Syntax

bool GetSparkline( PictureHolder & phDest, LPCSTR lpcszType, int nRes, int nSpark, DWORD dwOptions )

Parameters

phDest: [output]the holder to put the image into.
lpcszType: the image type:; "Bitmap" // (Bitmap); "EMF" // (Enhanced MetaFile, default); "W" // (Windows Metafile); "DIB" // (Device independent bitmap
nRes: additional info, like the resolution if bitmap.
nSpark: If >= 0, it is the index of the dataplot. If GPGETPICT_SPARKLINE_STYLE. Otherwise it should do all the dataplots and, if GPGETPICT_SPARKLINE_STYLE,
dwOptions: possible values (may combine):; EMBEDGRAPH_HIDE_AXES = 0x00000100, // hides Axes; EMBEDGRAPH_HIDE_LEGENDS = 0x00000200, // hides legends; EMBEDGRAPH_HIDE_SPECTRUMS = 0x00000400, // hides spectrums; EMBEDGRAPH_HIDE_TEXT_OBJS = 0x00000800, // hides texts; EMBEDGRAPH_SPARKLINE_LARGE = 0x00004000, // the copy in clipboard is larger than default; EMBEDGRAPH_SPARKLINE_CLIPBOARD = 0x00008000, // put a copy onto clipboard; EMBEDGRAPH_CACHE_IN_PAGE = 0x00100000, // cache image in page

Return

TRUE if succeed; FALSE otherwise
