Perf report while reading CZI file #1

Closed snowformatics closed 2 years ago

snowformatics commented 3 years ago

Hello Christoph,

I have a question. Python is printing constantly this report while reading a CZI file:

`* Perf Report

Image Width = 1600, Height = 1200, total MegaPixels = 1.9 MP m_ptEncDecPerf (excl I/O): 2475.000 milliseconds, 0.775758 MP/sec *** WARNING: 360 time intervals were measured as zero. This perf timer has insufficient precision! m_ptEndToEndPerf (incl I/O): 3303.000 milliseconds, 0.581290 MP/sec`

Do you have any idea what's all about this and how to supress this report?

This is probably coming from the jxrlib library, which is used by imagecodecs for the jpegxr codec. Make sure jxrlib is compiled with DISABLE_PERF_MEASUREMENT.
