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!

Setting fixed zoom boundaries

There are 2 ways to enter/define fixed zoom area's. These area's can be choosen: Defining area's can be done: Example:
lon=5, lat=52, delta lon =20, delta lat=15:
At centre point (lon,lat)=(5,52):
  • lat-range is 52-10 ... 52+10
  • lon-range is 5-15 ... 5+15.

    Defining area's in Prefercnces The format is:

    area<x>=(name=<name>", clon=<center_lon>, clat=<center_lon>, dlon=<delta_lon>, dlat=<delta_lat>
    area1=(name=Europe, clon=6.00, clat=56.00, dlon=19.70, dlat=21.00
    area2=(name="Atlantic 2", clon=-18.00, clat=42.00, dlon=19.70, dlat=20.00
    area50=(name="North west", clon=-142.00, clat=52.00, dlon=20.00, dlat=20.00

    Unexpected behaviour.

    A mix of data with different sizes may give sometimes problems. For example, GOES data may cover different parts: full disk, northern part etc. If a mix of this data is selected and then used to export images, then this willl give different results for the different GOES data, of course.
    But if the Preview button from the 'Files' pop-up is used to zoom in an area covered by all selected GOES items then only the first image will give the expected zoomed area, the others not. Making a movie this way is therefore not possible.
    This problem can be solved by defining/using a fixed area covered by all types of images. Now the different GOES data can be used to create images of the same part, or to create a movie. Also if the preview button is used.

    Background: preview defines the area relative to the x/y positions of the image, not using actual position.
    Defining an area does use actual earth positions, resulting in equally located parts of each source.
