Re: [libdmtx-open_discussion] .Net Wrapper Question

I few days ago someone from this discussion list replied to me (far...@as...<mailto:far...@as...>) about the MaxCodes problem of the .net Wrapper.  Unfortunately I lost your email address.  If you are reading this please contact me.  I have started using your new pure .net library, but have an important question.

Subject: .Net Wrapper Question

I have a question about the .net wrapper.  I appears that when a bitmap is decoded using the wrapper, the MaxCodes property has no effect.  Setting it to 1 does not stop the decode process to decode just 1 data matrix and then stop, instead it goes on for quite a long time (~20 - 30 seconds).   However setting the TimeoutMS does stop the decoding after the specified time period.

The problem is that this behavior does not happen with the command line dmtxread.exe when -N1 is passed as a parameter.  Using the same bitmap file as with the wrapper, the command line version decodes the data matrix in less than 2 seconds and then stops and prints the value, which is the expected behavior.  With the wrapper I have to specify a timeout of 5 seconds otherwise the decode process does not end.

Both the wrapper and the command line version use the same libdmtx.dll located in the Sys32 directory.  Has anyone experienced this problem?
