bf5c532269 Series of changes for the tiff encoder: 
* Added configuration options for the TIFF encoder. The options are:
   - compression: adobe_deflate(default), deflate, lzw, none
   - zlevel: 0-9
   - scanline: 1,0 (Forces scanline encoding)
 * Fixed bug in encoder with scanline where memory was being modified
 * by TIFFWriteScanline. A buffer is now created for each row to prevent
 * modification of the underlying image_data.

af4c2620aa Ignore overviews with 0 scale in pgraster 
refs #2551

Postgis raster_columns view is returning NULL values for raster
overviews with large scale factors. That issue in postgis is described
in http://trac.osgeo.org/postgis/ticket/3006

This causes two main problems:

  - The first overview with scale = NULL is wrongly chosen for rendering
    always

  - The messed up scaling factor causes the render symbolizer to spent
    an insane amount of CPU and memory to render a messed up tiles.

The patch in postgis is expected to be released with the new version, a
few months from now.

38da080f82 make concrete image_data type names more expressive and explicit about color channels/depth: 
image_data_32 -> image_data_rgba8
image_data_8  -> image_data_gray8
image_data_16 -> image_data_gray16
image_data_float32  -> image_data_gray32f

NOTE: currently image_data_gray16::pixel_type = std::int16_t (signed 16 bit int) to match GDAL
should we support unsigned types?

cdaca0ba11 Updated tiff processing so now the encoder will utilize different types of data as well as will use Tile based encoding in most situations, if the image is large will revert to scanline based encoding. 2014-12-03 18:41:49 -05:00
