command line cropping problem

[grouse]

I'm trying to use the command line mrsidgeoencoder.exe to crop an image.

Here is what i'm typing at the command prompt:
mrsidgeoencoder -i D:\2009_Ortho_Cut\NAD27\Humboldt_County_NAD27.sid -cropulxy 404870.624791 4523622.130743 -croplrxy 415974.566365 4512708.188170 -o D:\2009_Ortho_Cut\NAD27\H05N01E.sid -wf

I get the following error message: Cropping values in image (pixel) space must be integers.

I find this odd because the information listed under cropping switches in the Command line help show for example "-cropulxy float0 float1 Upper left XY position of a cropping rectangle".

Try adding -coord to your command to crop in coordinate space.

I added the switch -coord, and now get the error:

mrsidgeoencoder.exe usage error: extra arguments found (404870.624791 ...)

where 404870.624791 would be the floating point x coordinate that I presume would be needed for the switch,

-cropulxy float0 float1

Try this:

mrsidgeoencoder -i "D:\2009_Ortho_Cut\NAD27\Humboldt_County_NAD27.sid" -o "D:\2009_Ortho_Cut\NAD27\H05N01E.sid" -cropulxy 404870.624791 4523622.130743 -croplrxy 415974.566365 4512708.188170 -coord -wf

Got it to work by adding "geo" after -coord

mrsidgeoencoder -i D:\2009_Ortho_Cut\NAD27\Humboldt_County_NAD27.sid -coord [b]geo[/b] -cropulxy 404870.624791 4523622.130743 -croplrxy 415974.566365 4512708.188170 -o D:\2009_Ortho_Cut\NAD27\H05N01E.sid -wf

The only other thing I need is to have it create the world file. It seems the switch -wf is being ignored.

In the echo of information that follows I notice the info:

"Ignoring flag: -wf doesn't apply to MrSID optimizing.

When I crop through the GeoExpress GUI a world file is automatically created.

Robert,

I download the command line world file creator, and will use that after I've fininshed cropping, unless there is an easier method.

Thanks for your help, hopefully my problems are solved.

Oops! I left out "geo". Sorry about that.

The command line is pretty smart in that it "optimizes" when it sees an operation that only requires editing a MrSID G3 file. There is also no way to tell it not to do that at this time.

I'm not sure why it won't output a world file, but

mrsidgeoinfo -wf imagename.sid

will produce one.

I'll log this in our bug tracker.
