Hi,
Below is my third weekly report:
*What did I do this week?*
- Modified the PostGISRasterRasterBand::IRasterIO method, enabling it to
process the buffer(pData) containing the raster data for write
mode(GF_Write). After the datatype conversion it is ready to be written to
the query. In the meanwhile, I realized that while inserting a raster in a
table it is always broken into evenly sized tiles. So the default
implementation of GDALRasterBand::IRasterIO can be possibly used to handle
the write case.
- Implemented PostGISRasterDataset::InsertRecords method which creates
the insert query.
*What do I plan on doing next week?*
- Continue to write methods to create the sql query which will write
data to the PostgreSQL tables.
*Am I blocked on anything?*
- No.
