PhotoLayer plugin - Satellite GeoTiffs with transparency

[nohal]

Mike...
I have sent you the pull request implementing the detection of libgeotiff and linking against it and fixing the build an packaging on macOS

Technically the plugin works (read, builds and loads into OpenCPN), but I haven't been able to find any GeoTIFF it would show.

EDIT: Recovered my VentureFarther password (Why isn't there a link to it on the login page? ) and their GeoTIFFs seem to work...

Thanks very much Pavel.

I will work with the pull request tomorrow.

No way would I have got close to a solution myself.

Didier ... Thanks. Looking at your patch will also help my education!

Now builds with Linux.

A DEB package has been added to v0.1 for Linux users.

If making a KAP chart from a GeoTiff set the number of colours in 'Preferences' to, say, 64. The default setting of '2' will not work.

There are no warnings shown when downloading VentureFarther GeoTiffs. Thanks Jon.

Will you be making an OS X build of this plugin?

I tried to build it myself by installing dependencies through homebrew (gettext, wxwidgets, etc), Im able to cmake, but when I try to run the makefile I get a:

In file included from /Users/fgaruti/Downloads/photolayer_pi-master/src/PhotoLayer_pi.cpp:29:
/Users/fgaruti/Downloads/photolayer_pi-master/src/PhotoLayer.h:30:10: fatal error: 'geotiffio.h' file not found
#include "geotiffio.h"


Cheers!

Gaucho,


See post #16. Do you have a GeoTiff library on your system? Sorry, OS X is a mystery for me. Perhaps someone else can help.

Perhaps you have forgotten to install libgeotiff from homebrew?

Of course ... for some reason I didn't think that was a gnu package. Got that working.

Hi,

I'm trying to get the OpenCPN and the PhotoLayer plugin working on my Mac (OS Catalina). I've successfully installed OpenCPN and have been able to download charts from NOAA. I was able to compile the PhotoLayer plugin (dependencies installed via homebrew) and have a 'libphotolayer_pi.dylib' file in the folder OpenCPN.app/Contents/PlugIns. However, when I launch OpenCPN the plugin doesn't appear as an option in Options > PlugIns. Only the default GRIB/WMM/ChartDownloader/Dashboard plugs appear.

Can anybody point me toward a possible solution? I'm guessing maybe there's a file somehwere that needs to be updated with the libraries to check for plugins, but I'm hesitant fiddle with the OpenCPN Config file without a better understanding of what I might need to do.

Thanks for any help!

Thanks for looking at this. I have just started work to enable compiling on MacOSX. At the top of the list!

I have put a MacOSX installer on GitHub releases:
https://github.com/Rasbats/photolaye...ses/tag/v2.1.2

I am using Catalina.

There is a problem with the images but the plugin works. The key to finding libGeoTiff was to comment out the IF(UNIX)/ENDIF(UNIX) bit in CMakeLists.txt. I will do some editing for Apple and look at those images.

Updated to allow installation on MacOSX. You will need to install the libgeotiff library.

The images problem has been resolved.

Hi Mike,

Thanks so much for posting this so quickly! I re-installed the package with the updated *.pkg and it seems to be working perfectly. Double thumbs up for the pkg installer - it made things a lot easier than zigzagging through compiling via bash.

Great package!!

PhotoLayer is now on the list of managed plugins.

For Windows users the Microsoft Paint program used to be the only graphics program that retained the geo-referencing metadata after editing.

Since version 4.2.2 'paint.net' has had this capability. I have used the program for other graphics work and it is brilliant. For editing geotiffs it is a huge leap forward. Free, but I felt it was worth a donation.

But not yet available in the "Master" catalog of plugins.
It probably takes just a little patience.

appears to have been accepted. Mike has UKtides awaiting now.
