5.32 PNG Image Export (Thumbnail) 135
If any of FE2_PNGEX_AUTO_EXPORT_COUNT, FE2_PNGEX_EXPORT_CUE_POINTS
or FE2_PNGEX_EXPORT_TIME_STRING are enabled and a time is duplicated, the duplicate
time will be discarded.
If FE2_PNGEX_EXPORT_INTERVAL is enabled and at least one of FE2_PNGEX_AUTO_-
EXPORT_COUNT
, FE2_PNGEX_EXPORT_CUE_POINTS or FE2_PNGEX_EXPORT_-
TIME_STRING is enabled, the time interval based PNG image will be generated using the
frame subsequent to the frame that would otherwise have been duplicated if times overlap.
Incorrect duration:
If the duration is unavailable (i.e., Flix2_GetSourceDuration() returns -1) the first FE2_-
PNGEX_AUTO_EXPORT_COUNT frames will be output.
If the duration is misreported (i.e., >actual) and not all requested PNGs have been output, one
additional PNG will be generated on the last frame.
