ImageSolver with SurfaceSplines

[Juan Conejero]

The functions for file access in PJSR are very limited

The File object allows you to open, create, seek, read and write any file. What else?

Sorry Juan, I have mixed in my mind several different problems and I have made it look worse than it is.

When writting my scripts I've had several problems because PJSR lacks some capabilities such as:

• Being able to read text files line by line.
• Read/write compressed files (i.e. zlib)
• XML parser/writter.

However, most of these would not be necessary for offline catalogs.

The second problem is that in big catalogs with nearly a billion (10^9) of stars without indexation it would take forever to extract the stars in the field of view of the image. It would require to implement some kind of indexation for being able to find quickly the required stars. This would require another script for building the catalogs from the source data.

Hello
I don't know how are doing SkyChart software when they display UCAC or USNO catalogs. It is fast.

I know at least 3 methods for doing that and in my job I develop software that uses gigabytes of cartographic data. However I do these scripts in my free time and I have not enough of it for doing more...

Don't worry, I know what you mean 
Just in the future, if you think about this possibility it should be nice. But not necessary.


If you can do before an even better distortion correction algorithm     
I will explain you by MP. Not right now because I don't have enough time, as I need a complete explanation of the "problems" for special non uniform distorded optics), then I need to send you some example...
