Q&A - Question

Hello,
I am trying to create a new PixelStore in a PostgreSQL (v. 9.5) database running as localhost on Win 7. I am using TatukEditor 4.59.0.12869. I created a pix_test_3.ttkps file with the text in the code snippet below. I am connecting to the database via the PostgreSQL ODBC Driver(UNICODE). I am able to load a PostGIS vector layer from the database using a .ttkls file and have no issues reading it, although I've not been able to make edits.

In TatukGIS Editor, I load a small aerial image. Then I go to File --> Export To Image, select the pix_test_3.ttkps file, allow overwrite, set to document to save file space while testing, and then proceed.

After it starts running, I get an error window stating 'Error on export image
0180 Unexpected error upon drawing "" layer. Exception message : Operation is not allowed in this context'

In the database, I have a new table titled "pix_test_3". It contains a single row, with nlevel=1, nrow=0, ncol=0 and cell=null.

There is also an entry in the ttkgispixelstore2 table that appears to have appropriate x and y min and max and projection. Interestingly, the name in this table includes the schema ("public.PIX_TEST_3"), while tests I tried before upgrading to the most recent stable version of TatukEditor do not include the schema ("PIX_TEST"). I have also tried a "pix_test_4" to see if the error was due to mixed upper/lower case, but got the same error.

Using the 32-bit Editor gave an error with the ODBC driver, and changing layer in the .ttkps file to "public.pix_test_5" gave a cross-database references error.

Do you know what I am missing?
