Chart Edition, Last Correction, and Cleared Through NLM information cropped off RNC?

Hi everyone,

Running 4.6.1 on a windows 10 tablet.

Using RNC charts downloaded using the "ChartDownloader 1.2" plug-in, it looks like the bottom of the chart is cropped/clipped a tiny bit, that seems to cut off the chart edition, last correction, and cleared through NLM dates and info off the bottom left of the chart.

For example, see: Chart 18773

At the bottom left you can see the info I'm talking about. But viewed in OpenCPN, it's not there.

Ideas?

It's possibly a question of different chart pictures from NOAA, for different purposes.

If you download your chart from this page Chart Downloader for NOAA RNC&#174 and then extract the picture from the kap file with imgkap by
Code:
imgkap 18773_1.KAP 18773_1.png
and view this picture, you will find the same "problem" as in OpenCPN's view.

My conclusion is that NOAA does no longer print the update info on the charts, but the info is contained in the kap files text header.
The only problem I can find with OpenCPN is that the NTM line in the kap file is not processed. This is the line for 18773_1
Code:
NTM/NE=43.93,ND=05/06/2017
OpenCPN tells the update date, but not to which NTM.
