Use FE2_PNGEX_CP_EVENT, FE2_PNGEX_CP_NAV, or FE2_PNGEX_CP_ALL to specify the types

of cue points for which the PNG exporter should export PNG images.

sc = Flix2_AddFilter(&png_exporter_plgn, flix, FE2_FILTER_PNGEX);

if (sc == ON2_OK)

// generate PNGs for all cue points

sc = Flix2_FilterSetParam(png_exporter_plgn,

FE2_PNGEX_EXPORT_CUE_POINTS, FE2_PNGEX_CP_ALL);

sc = Flix2_AddFilter(&png_exporter_plgn, flix, FE2_FILTER_PNGEX);

if (sc == ON2_OK)

// create a PNG image of the first video frame

sc = Flix2_FilterSetParam(png_exporter_plgn,

FE2_PNGEX_EXPORT_FIRST_FRAME_PNG, on2true);

if this parameter is speciﬁed in a call to Flix2_FilterSetParam()

sc = Flix2_AddFilter(&png_exporter_plgn, flix, FE2_FILTER_PNGEX);

if (sc == ON2_OK)

// generate a PNG every 10 seconds

sc = Flix2_FilterSetParam(png_exporter_plgn,

FE2_PNGEX_EXPORT_INTERVAL, 10000);
