This topic accompanies the Styling Table Fields topic to provide reference detail on styling fields in tables for geom and tile data types. Please review the Styling Table Fields topic for an introduction and step by step examples before proceeding with this topic.
Geometry styles provide a basic display of the data type (geom, geomwkb, or geommfd), the data type with the number of bytes in the object, the object type, or the object type with the number of coordinates and branches. Objects with Z values in the geometry will be reported with a z appended to the object type: areaz, linez, or pointz.
Language choices will affect the separator character used in the style and in the number of bytes. For example, a comma , character is used as a separator for neutral and US English, and a dot . character used as a separator when a European language is specified. The separator character between displayed parts of the style will also switch to match the language, for example, switching to a semicolon ; character for German in Germany. For example, <geom, 4,836 b> for English in the US as compared to <geom; 4.836 b> for German in Germany.
The number of bytes reported is the number of bytes in the value expanded into RAM, with no compression.
b |
Data type name: <geom> or <geomwkb> or <geommfd> |
B |
Data type name with number of bytes: <geom, XXX b> |
t |
Type of geometry (default): <geom, line> |
T |
Type of geometry, the number of coordinates and for more branches than 1, the number of branches after a slash: <geom, line, 200 c / 3> |
Using the t option for the Geom field, the T option for the GeomWKB field, and the B option for the GeomMFD field, with neutral choice of Language for all three fields:
Using the t option for the Geom field, the T option for the GeomWKB field, and the B option for the GeomMFD field, with de-DE (German as used in Germany) choice of Language for all three fields:
Tile styles provide formatting to report the number of bytes in a tile, the size of the tile and number of channels, or the size of the tile and the number of channels and data type used in channels. When the number of bytes in a tile is reported, that is the size in bytes of the tile expanded into RAM, with no compression.
b |
Data type name: <tile> |
B |
Data type name with number of bytes (default): <tile, XXX b> |
t |
The width x height size of the tile, with the number of channels when there is more than one channel (default): <tile, 128 x 128 x 3> |
T |
The width x height size of the tile, with the data type and number of channels when there is more than one channel: <tile, 128 x 128, float64x3> |
A typical default display for an RGB image is seen below:
Right-clicking on the column header for the Tile field and choosing Style, we can pick the T option to show the data type used within channels.
The above illustration is for neutral language.
We can launch the Style dialog again and choose German language as used in Germany (de-DE) to alter the displayed style, switching semicolon ; characters for the comma , characters used in US style grouping.
Style: Binary, Boolean, UUID Fields
