#8 IfpImage Not creating graphics

[Michael Foland]

When I go into Products > Scripts >PNG Image, it uses the gfeConfig. However when looking into the process it runs sh /home/gfe/gfeInstall/var/gfe/bin/gfei and says no such file or directory.

Not sure what is going on here. Would love to see GFE make grids. See my previous post on the attempts to get this working.

In this file: https://sourceforge.net/p/gfed/code/ci/master/tree/data/textFiles/GFECONFIG/gfeConfig.GFECONFIG

Change the SITE in the # Product Generation Scripts appear under the product generation menu

on the GFE.

Scripts = [
"Png Images...:" +
"{home}/bin/gfei -m ifp.Image -u SITE -h {host} -p {port} " +\
"-c {entry:ConfigFile:testIFPImage} " +\
"-o {prddir}/IMAGE",

"Ascii Grids...: " +
"{home}/bin/gfei -m ifp.AG -h {host} -r {port} " +\
"-o {prddir}/AG/{ztime}.ag " +\
"-d {productDB} ",

"MakeD2DFile: " +
"{home}/bin/gfei -m ifp.makeD2DFile -h {host} -r {port} "
]
-u {site}

to make it work with the config file!

[Michael Foland]

When I first ran the script, it said /home/gfe/gfeInstall/var/gfe/bin/gfei didn't exist.. which /home/gfe/gfeInstall does exist. I created the gfe and bin folder respectively, and I copied the gfei file in there. The script WORKED... However it said I had some Png_Params missing, even though I had things defined in the gfeConfig script. See the attached.

[Michael Foland]

Got the PngImage to work... however after making config edits.. it doesn't want to either save them or something.. It gives me a black background, and doesn't show it like it should on like a white map, with gray counties, and the actual grid stuff with the values.

Second problem, I created a WX Grid, and it didn't even send that to PNG. I attatched the image issue that has the MaxT.

[Mike Romberg]

As you have discovered, you can't use 'gfeConfig' as a configuration file for the ifp.Image program. I have no idea why it was ever set as the default. I changed the default one to 'testIFPImage' which does work.

I've also fixed some of the code which broke things running as a script with the new install directory structure.  It now runs for me both from a development environment and an installed setup.

  The line stipple code was a bit broken from the port to c++14.  It is now working as well as it used to.   The libgd library ifp.Image uses has come a long ways since ifp.Image was written.  It now has anitialiasing, alpha blending and freetype font support.   At some point I may add these features to ifp.Image.

     Also, the SITE bit in the commond line to ifp.Image has nothing at all to do with the "site" the gfe is configured for (such as BOU).   It is the user name in the BASE/SITE/user scheme used by the configuration loader.   The intended way to configure an ifp.Image configuration is to start the gfe with the SITE user and save a gfeConfiguration which points to an ifpImage configuration.  This way all users will see and use the same thing.   See the documentation on details for all these things.

       Finally, the weather grids used by the testIFPImage configuration seem okayish to me.  They are displaying as a graphic and not an image in this file.   They may need adjustments to the whole fill pattern to Wx type mapping thing (found in testIFPImage).   It has been a while since I've looked at that.

I'd love to see the grids fill like how they do on the nws.. it also looks
like ifpImage is going to a test db. Im not sure how to get it set to Fcst
and official

Over my grids can I also output city names? I'd like to show one weather element at a time... whereas in some of the grids, multiple elements show.

[Michael Foland]

I did a fresh install, and when I go to run ifpImage...

I get this after the command runs, when I look in the Process Monitor:

PngWriter.py 593 EVENT: ifpIMAGE Starting
PngWriter.py 596 EVENT: Build Date: Tue May 1 05:49:48 2018 Built By: gfe Built On: localhost.localdomain (linux) Version: 1.10.0 May/01/2018

PngWriter.py 40 EVENT: Configuration File: testIFPImage
PngWriter.py 460 EVENT: No grids to generate
PngWriter.py 650 EVENT: ifpIMAGE Finished

So -- I was able to take some of the info from the TestIFPImage, and edit the Png_params, and I was able to get it to work. I made a MaxT grid, and you can see the attatched. Now would be nice to get it to work like this for different elements: https://graphical.weather.gov/images/pah/MinT1_pah.png

Obviously if I were to show a logo, I'd be putting my own logo and text in between :) I spent about an hour and a half getting this progress working! I can attatch my gfeConfig if you'd like.

--EDIT.. In the attatched.. While I generated it as the MaxT element... These certainly are not temperatures. Not sure what happened here!

[Michael Foland]

I believe on that image it is topo and not maxT. Not sure why it didn't
generate the MaxT grid.

There is alot of documentation that can be found by poining your browser at:

file:///path/to/where/ho/have/gfe/source/GFESuite/doc/onlinehelp/index.html

In particular, the ifpImage documentation is at: GFESuite/doc/onlinehelp/ifpIMAGE.html

That plus the comments in gfeConfig may make it a bit easier to setup the images you are looking for.

NOTE:  There is no longer a specific ifpImage program mentioned in the documentation.   I moved all the two dozen or so stand along programs into a single one (gfei).   So, the old ifpImage program is now 'gfei -m ifp.Image'.   Yes it is a bit more typing.  But if gfe is installed in something like /usr/local then there are not two dozen extra programs in /usr/local/bin :).

EDIT:  Also, the ifpServer is now a web server.  So, if you point your browser at http://localhost:8044/ you will send back html.   The documentation is at: http://localhost:8044/doc/onlinehelp/index.html

[Michael Foland]

I was able to use the documentation to get the grids to actually generate an image... However, I cannot for the life of me get the temperatures to also show as text for points... and not all the cities are showing like they should be. Is there a new city database out there or something? See my attatched image.

[Mike Romberg]

The points at which values are displayed are called samples. Groups of samples are called samplesets. To get ifp.Image to display samplesets you need to:

• Create and save a sample set using the gfe. 1) select the sample tool 2) click on the points you want. 3) Use the Maps > Samples > Save dialog to save the set. You probably want to do this as the SITE user as ifp.Image is run as that user from the script dialog and all other users will see this sampleset too.
• Then set the variable DefaultSamples = ['yourSampleSetName'] in the config file used by ifp.Image

As for the cities map. Check the section of the documentation about configuring maps. The cities shapefile has alot more cities in in that the gfe will use by default. If I remember correctly the default filters out smaller ones so that large metro areas are not a huge swarm of points. I believe you should be able to customize the cities map for your needs.

[Mike Romberg]

ifp.Image seems up and running again. So, closing this ticket. Open new tickets for any additional issues with the operation of ifp.Image.
