Good question. I imagine it is extra work for Frank that falls low on the priority list. :)

That's excellent to know! Thanks a lot Martin. Instead of getting segfault, I could use that to exist peacefully in case the driver does support the Create() function. Just of out of curiosity, why JPEG driver does not have the create function and only supports CreateCopy()? The Create() function could be easily implemented using MEM and CreateCopy(); instead of relying on the user to do this every time a JPEG driver is used. With best regards. ~Belaid.

Date: Wed, 29 Jul 2009 11:56:04 -0600 Use: if (!pDriver->TestCapability(ODrCCreateDataSource)) to test create capabilties of the driver. I think jpeg driver only supports CreateCopy(). You could use the Memory dataset to create a different size dataset and then use the jpeg driver to save it to disk.

Hi Everyone, When I try to use GDALCreate() on the JPEG driver, I got the following error: "GDALDriver::Create() ... no create method implemented for this format." Does is this mean that JPEG driver does not have its GDALCreate() function implemented? Any example on how to use JPEG driver is appreciated. As always, any help on this is very appreciated.
