In EhrmannS/geometr: Generate and Modify Interoperable Geometric Objects

geometr 0.4.0 - new frontend and backend

• change all function names to geo_*
• move all getters and setters to an external package, namely geomio, where can be used by others without having to load geometr. This allows geometr to focus primarily on the geom class and handling all "geometric" operations

geometr 0.3.0 - fast visuals

• revise visualise and all its' helpers to make plotting faster.

geometr 0.2.11

• include SpatRaster support
• exclude objects of other packages and instead reconstruct them with gc_* functions of geometr.
• fix a bug that would not allow zooming

geoemtr 0.2.10

• include ungroup argument in gt_pull
• revise crs-management of sp

geoemtr 0.2.9

• revise documentation of setTheme in an effort to make it more accessible.
• include rounding of legend tick labels

geometr 0.2.8

• gs_point now allows to create an empty geom that contains only "window" information.
• visualise can now plot empty geoms, making use of their "window" information, to create an empty surface for sketching.
• the option to use a template has been removed from all gs_* functions. The new workflow to sketch geoms is now either via an already open plot, or via a sketching surface (see above changes).
• the window slot now only contains the lower left and upper right corner, instead of each coordinate of the rectangle.
• removed function gt_sketch, as it is redundant.

geometr 0.2.7

• included the @extent-slot for faster processing of large objects where it takes long to find min/max values of coordinates.
• getRes now returns a vector, instead of a tibble
• getLayers now returns all layers in a list (no subsetting more possible)
• getGroups now returns for RasterLayers without a raster attribute table (RAT) an empty tibble.
• gc_geom now only adds groups to the group attribute table in case the input raster actually contains a RAT.
• print-method of gtTheme has been beautified (it now also shows whether an attribute is scaled to some parameter)
• In case an object doesn't have any provenance information, getHistory now prints that this object has been loaded from memory.
• all spatstat getters/setters (for class ppp) have been removed temporarily.

geometr 0.2.6

• identifying and setting groups in gridded geoms has been refined. Several layers are by default stacked, but it is now also possible to create a list of separate geoms per layer with gc_geom(..., stack = FALSE).
• \"images\" are now handled by being able to create a grid geom with hexadecimal values by setting gc_geom(..., as_hex = TRUE).
• subsetting has been moved out of the respective getters into gt_filter(), it also includes subsetting x and y values of the vertices.
• pulling columns can now be done with gt_pull().
• new getters getCols(), getRows() and getNames().
• removed the @scale-slot from from the geom class, because it is no longer needed.
• visualise() has been revised so that it fully supports plotting all geometric classes that have getters defined.
• all previously existing gt_*() functions were revised so that they too support all geometric classes that have getters defined.
• some code adaptions that come with those changes.

geometr 0.2.5

• remove 'tiny map' from print method of grid geom
• allow specification of 'precision' for getRes()

geometr 0.2.4

• rewrite setPoints(), setFeatures() and setGroups() so that new tables can only be set via joining by the primary key (fid, fid and gid respectively).

geometr 0.2.3

• gtTheme now contains a separate slot for all information that relate to the colour scale of values and the legend.
• accordingly, all functions that deal with that information were adapted.
• other minor bug-fixes

geometr 0.2.2

• included a faster method to determine IDs of paths and sub-paths of grobs when plotting.
• getLayer() also for sf and Spatial objects.

geometr 0.2.1

• incl. group information in geom show-method
• implemented more efficient routine for extracting features and points from sf-objects
• when setting a new features/groups table on a geom, the old respective table is overwritten from now on.
• a gtTheme now also supports a "missing colour" that will be assigned to NA-values when a quick-option is used in visualise()
• other minor bug-fixes

geometr 0.2.0 - grid update

This update introduces the geom type 'grid', which is meant to store raster data. It stores as @point slot a compact version that gives (in both x and y dimension) the three values origin, number of cells and cell distance/resolution. It stores values in run-length encoding (rle) (if that is smaller than non-compressed). The @feature slot of a grid geom can contain any number of tables that would correspond to layers in a raster. It can store in the @group slot an attribute table per each of the layers.

The following functions have been modified:

• gc_geom() now has a method to convert Raster objects to grid geoms.
• get/setTable(x, slot = "point") has been moved to get/setPoints(x)
• get/setTable(x, slot = "feat") has been moved to get/setFeatures(x)
• get/setTable(x, slot = "group") has been moved to get/setGroups(x)
• getPoints() for grid geoms extracts the compacted @points slot into the interoperable table this getter is supposed to hand out.
• getFeatures() for grid geoms reconstructs fid for points and extracts rle tables, if they exist.
• makeObject() is not a generic anymore but is now a function based on getters. That means that any class that has the respective getters defined, can be plotted with visualise() (which includes now sf and sp objects).
• getSubset() has been integrated into the respective getters, i.e., to get a subset of points, use getPoints(x, fid == 1), etc.

The following functions are new:

• gc_raster() to transform a grid geom to an object of class Raster*.
• getRes() to get the resolution of a gridded object.
• getLayer() to extract layers from an object that has layers.

geometr 0.1.1

• fix vertex checks also for polygons when they are created via gs_sketch().

geometr 0.1.0

• initial release
