As this comes with a significant performance penalty, this
feature must be enabled using the command-line option --drawair
For best results, the color of air should be fully transparent,
so that underlying nodes will override it.
This is useful to show invisible ('air' or 'invalid') nodes in blocks
that are in the database using a different color than blocks that are
not in the database (which will have no color at all, causing the
background color to show).
Minetestmapper can now be installed into a proper directory hierarchy
(instead of all files being dumped into /usr/local/. for instance.)
Non-hierarchical installation (or creation of a non-hierarchical archive)
is also still supported, and remains the default, for backwards compatibility.
Packaging on windows remains unchanged, due to lack of infrastructure :-)
A colors file can now specify other colors files, from which
additional node color specifications will be read. This allows, for
instance, using system-installed colors file for most colors,
and only overriding some of its colors in a custom colors file.
As a purpose of using a custom colors file may be to leave the colors
for some nodes undefined, it is now also possible to undefine a
previously defined node color (i.e. after reading another colors file
which defines a color for the node).
- Continue processing if libraries are not found (so that all missing
libraries are reported)
- Set compiler flags correctly if CMAKE_BUILD_TYPE is not set (fixes bug #0)
- Make CMAKE_BUILD_TYPE=Release the default
- Increase optimisation level for Release
Supported figures are points, lines, ellipses, rectangles
and text.
The figures' locations can be specified using either world
coordinates, or map coordinates.
In preparation for future changes.
New geometry and new coordinate syntax has been added as well:
Additional node coordinate formats:
<block>#[<node>]
<block>.[<node>]
Additional geometry formats:
<x1>,<y1>:<x2>,<y2>
<x>,<y>:<w>x<h>
Also: the old geometry behavior (block granularity and map shrinking)
is now enabled only if the old geometry format is used (for compatibility)
Values: 0: fully transparent, 255: fully opaque.
Note that this doesn't yield the expected color blending just
yet, due to libgd messing it up. (Seemingly, the libgd arc
drawing function draws some pixels repeatedly, resulting in a
more opaque circle than desired)
(empty map blocks are blocks that have no associated block data
in the database (which should probably not happen), or that are
not in the database at all, but that are still queried for some
reason (which is unlikely))
