Fail to read DmxChannelCount

[jordan-walters]

Describe the bug
Opening the attached .gdtf file, and callingthe GetDmxChannelCount for the 2nd mode "Dmx Mode", returns 11.
The channel count should be 20.

To Reproduce
Steps to reproduce the behavior:

1. Using libMVRgdtf, ReadFromFile the attached gdtf file.
2. Using returned fixture pointer, call GetDmxModeAt(1) to get the mode "Dmx Mode".
3. Using return dmxMode pointer call GetDmxChannelCount to get number of dmx channels for that mode.
4. Value returned is 11.

Expected behavior
The value returned should be 20

Hi @jordan-walters ,
Can you send me more information about the issue? I’m not able to reproduce it in Vectorworks. The only issue I can see is that the first mode contains virtual channels.

[jordan-walters]

GetDmxModeAt(int index) starts at index 0, so GetDmxModeAt(1) is getting the 2nd mode.
The 2nd mode (called "DMX Mode") contains 20 channels but GetDmxChannelCount(size_t&) returns 11.

Yeah, I tried to reproduce it, but the only issue I am seeing is that on the first channel about the virtual modes. I am getting 20 channels on the second mode.
