Examples

EX1

make black line browser plot with XYYY, and then run GraphPage_ExportMultiFrame_ex

#include <../Originlab/GraphicalExport.h>
void GraphPage_ExportMultiFrame_ex()
{
	GraphPage gp = Project.Pages();
	string strFileName = GetAppPath() + gp.GetName() + ".avi";
	
	double dWdith;
	RECT rect;
	compute_page_export_inch(gp, 1, dWdith, TRUE, &rect);
	int nDPI = 600;
	int width = (int)convert_size_to_specified_unit(dWdith, UNIT_INCH, UNIT_PIXEL, nDPI);
	int height = (int)round(RECT_HEIGHT(rect) * width / RECT_WIDTH(rect), DEFAULT_DECIMAL_PLACES);
	
	OVideoOptions_t vidOpts;
	vidOpts.nCodec = 0;
	vidOpts.dFPS = 1;
	
	LPVOID pOpts = NULL;
	pOpts = &vidOpts;
	
	OFlipOptions_t flip;
	flip.nShift = 1;
	
	int err = gp.ExportMultiFrame(strFileName, "avi", width, height, pOpts, &flip);
	if (err == 0)
		out_str(strFileName);
	else
		out_str("fail");
