On Windows, minetestmapper now uses the colors files from the
directory where it is installed.
If the last directory is named 'bin', that part is stripped,
and the resulting directory, and a subdirectory named 'colors'
are searched.
All depends on the whether on invocation, argv[0] contains the full
path of the exe file. It works under Wine when compiled with MinGW.
I haven't been able to test on a real copy of windows, or when
compiled using msvc, but I assume that will work too.
As tests using --sqlite-cacheworldrow showed a consistently
lower performance than without, this option was effectively
disabled. It is still recognised for compatibility, but
it may be removed some time in the future.
Most of the content of README.rst was moved to a separate
user manual, and to a build manual.
The README was simplified to provide just the most important
information.
The user manual was extensively reworked, and beautified with images.
--heightmap: generate the height map, in colors
--heightmap-grey: use shades of grey instead of colors
--sealevel <n>: define the sea level (below sea level is drawn in blue)
--heightmap-scale <f>: scale the heights by f (for the purpose of
color selection)
When generating a heightmap, a special colors file is needed,
that defines just the blocks that should be considered part
of the ground. That means that normally, any plants, special
nodes and water should not be included.
The option --tiles has two new possible values: 'block' and 'chunk'
'block' creates tiles corresponding to map blocks
'chunk' creates tiles corresponding to map chunks
(chunks are the unit of map generation).
An option --chunksize was added to manually override the chunk size.
Note: on the y-axis scale, the block coordinates are rendered above
the line, instead of under the node coordinate, as that makes
them adjacent to the block they refer to.
for illustration: create a map with --drawscale --tiles=16 --tileorigin=world.
this makes the tiles correspond to the map blocks.
Consider a point with y-coordinate 64. It is part of a map-block with y=64..79.
This block is located at and above the line corresponding to y=64. On the y-axis,
it is therefore most intuitive to render the block coordinate above the line.
As the best color for water depends on the rendering parameters
(i.e. the --drawalpha mode: none, average or cumulative), two
additional colors files are provided for these alternatives.
This new mode averages the colors of all transparent blocks, instead of
making the colors progressively darker and more opaque.
This 'average' mode is now the default when using --drawalpha. It can be
explicitly selected using --drawalpha=average. The old modes can be selected
using --drawalpha=cumulative[-darken].
It is recommended to change the colors of water as well. These are in a
separate patch.
