AVI file Windows problem.
If Windows Explorer crashes after entering a directory containing a avi file generated by xrit2pic:
Execute the following command in a command shell:
regsvr32 /u shmedia.dll
This prevents Windows Explorer from analyzing avi files.
(Note: As far as I know this is a Windows Explorer bug. On my Windows-XP I don't see this problem.)
Quick reference guide.
Using xrit2pic in combination with MDM.
It is not possible to let both xrit2pic and MDM both act from the 'received'
directory at the same time.
If MDM is used for MSG data management then xrit2pic can still be used as post-processor.
Xrit2pic can read the jpeg files created by MDM from the original received files.
Drawback is that jpeg-files are lossy.
Especially with low luminance values and/or zoomed in the quality is noticeable
degraded compared to using the original received files.
NOTE: If temperatures are important, e.g. if the special mappings (airmass, dust etc.)
are used, make sure that MDM translates all needed IR-files into mode-A Temperature coding.
By default this is the case, except fow the 2 WV channels!
What to do:
- Find out the location where MDM puts the JPEG files.
- In xrit2pic, open the Preferences window (menu Edit->Preferences).
- Go to tab "Directories".
- Enter the directory containing the top of the tree containing the
JPEG files, in box "Archive directory".
Add full pathname. E.g.:
Suppose your JPEG files are under c:\HRIT\2007\06\01 etc.
The path to enter is:
c:\HRIT
- Click on 'Save it', to save this setting, and close the Preferences window.
- Stop and Restart xrit2pic.
- Go to tab "Archive". In the left part you will see the 'Years' directory.
- Open this tree item to see the month folders.
- If you want to see more click on 'Update'. This will update the tree
with all subdirectories and file count.
- Select one or more days directories containing files you want to process.
- Click on "Load selected".
- Now xrit2pic jumps to the Main tab and you can do the data processing.
Tips and tricks.
- In Preview: No need to wait for draw finishing;
during drawing you can already give zoom actions:
set cursor on area you want to zoom in, and type I , wait for reaction.
Zoom is done as soon as processing of a segment is finished, so this may need a few secs.
- Stop drawing: Press escape until the upper-right red "led" is off.
- Setting fixed zoom boundaries using lon/lat: (Preferences, tab 'Mappng', box 'Zoomed boundaries (degrees)')
- Determine and set in preferences center lon and lat.
- Determine and set in preferences delta lon and lat. Note:
- delta lon is valid for center lat.
- delta lat is valid for center lon.
Example: lon=5, lat=52, delta lon =20, delta lat=15:
at lon=52 lat-range is 5-15 ... 5+15.
at lat=5 lon-range is 52-10 ... 52+10
Basically, if xrit2pic can show positions in lon/lat then it will use
center and delta positions instead of percentages, except if one of the deltas is zero.
Known problems.
- Temperature doesn't work for AVHRR yet (includes fire detection)
Reported/known bugs.
- Closing preview window seems to cause now and then program crash?
Can't reproduce it here. Let me know if you see this, and tell me the circumstances when it happens.
Work-arounds: Wait until drawing stops (see 'Tips and tricks') or use the File->Dismiss menu item.
