|
| 3 |
|
* Thuban/Model/classgen.py (ClassGenerator.GenQuantiles): Remove |
| 4 |
|
references to 'inf' and use new Range __init__ to pass floats |
| 5 |
|
directly rather than converting them to strings first. |
| 6 |
|
Fixes RTBug #1876. |
| 7 |
|
|
| 8 |
|
* Thuban/Model/classification.py (ClassGroupRange.SetRange): |
| 9 |
|
Use new Range ___init__ to pass floats. |
| 10 |
|
|
| 11 |
|
* Thuban/Model/layer.py (RasterLayer.__init__): Test if the |
| 12 |
|
filename is a valid image file. Throw IOError otherwise. |
| 13 |
|
|
| 14 |
|
* Thuban/Model/range.py: Brought over new Range from SciParam that |
| 15 |
|
is immutable and has an __init__ which can accept floats. |
| 16 |
|
|
| 17 |
|
* Thuban/UI/mainwindow.py (MainWindow.AddLayer): Move OpenShapefile |
| 18 |
|
into try block. AddLayer doesn't throw any exceptions anymore. |
| 19 |
|
(MainWindow.AddRasterLayer): Move constructor of RasterLayer into |
| 20 |
|
try block. |
| 21 |
|
|
| 22 |
|
* Thuban/UI/projdialog.py (GeoPanel.__init__): Put Degrees as |
| 23 |
|
the first item in choices. Fixes RTBug #1882. |
| 24 |
|
|
| 25 |
|
* Thuban/UI/renderer.py (MapRenderer.render_map): Check if scale |
| 26 |
|
has gone to 0 which is a serious problem. abort. |
| 27 |
|
(MapRenderer.draw_raster_layer): Catch IOError seperately and |
| 28 |
|
print the error from GDAL. |
| 29 |
|
|
| 30 |
|
* Thuban/UI/tableview.py (TableGrid.__init__): Call |
| 31 |
|
ToggleEventListeners to turn on listening. |
| 32 |
|
(TableGrid.ToggleEventListeners): New. Turns event listening on |
| 33 |
|
and off so as to prevent excessive messages. |
| 34 |
|
(LayerTableFrame.OnQuery): Use TableGrid.ToggleEventListeners |
| 35 |
|
to suppress excessive messages when selecting many rows. |
| 36 |
|
Fixes RTBug #1880. |
| 37 |
|
|
| 38 |
|
* Thuban/UI/view.py: Added checks against if scale == 0. This |
| 39 |
|
is a serious problem that can occur when an image without |
| 40 |
|
geo data is loading and causes the map projection bounds to |
| 41 |
|
go to infinity. Right now, the solution is to simply try |
| 42 |
|
to recover. |
| 43 |
|
|
| 44 |
|
* extensions/thuban/cpl_mfile.cpp (MFILEClose): Make sure |
| 45 |
|
to set the MFILEReceiver attributes even if the data is NULL. |
| 46 |
|
|
| 47 |
|
* extensions/thuban/gdalwarp.cpp: Improved the error handling |
| 48 |
|
and passed GDAL messages back up to the Python layer. Also |
| 49 |
|
tried to fix some memory leaks that were present in the original |
| 50 |
|
utility but didn't matter because the program aborted. |
| 51 |
|
|
| 52 |
|
* test/test_range.py: Copied over tests from SciParam. Removed |
| 53 |
|
tests against importing. Fixes RTBug #1867. |

| 58 |
|
test code |
| 59 |
|
(LoadSessionTest): Split into one class for each test and turn |
| 60 |
|
LoadSessionTest itself into the base class for all such session |
| 61 |
|
tests. |
| 62 |
|
(ClassificationTest): New base class for load tests that test |
| 63 |
|
classifications |
| 64 |
|
(TestSingleLayer, TestLayerVisibility, TestClassification) |
| 65 |
|
(TestLabels, TestLayerProjection, TestRasterLayer): New classes |
| 66 |
|
for the individual tests |
| 67 |
|
|
| 68 |
|

| 69 |
|
file loading tests |

| 72 |
|
|
| 73 |
|
* Resources/Projections/defaults.proj: Renamed 'Universal Transverse |
| 74 |
|
Mercator' to 'UTM Zone 32' as a more convenient example. |
| 75 |
|
Added 'Gauss Krueger Zone 6'. |
| 76 |
|
|
| 77 |
|
* Data/iceland_sample_raster.thuban: political polygon now |
| 78 |
|
filled transparent to have the raster image visible at once. |
| 79 |
|
|
| 80 |
|
2003-05-21 Frank Koormann <[email protected]> |
| 81 |
|
|
| 82 |
|
* Thuban/UI/mainwindow.py (MainWindow): Renamed _OnClose() back to |
| 83 |
|
OnClose() to keep in sync with extensions. Internally Thuban |
| 84 |
|
still uses "underscored" names. |
| 85 |
|
|

|
This puts back Raster layer support. These layers support projections |
| 89 |
|
through the GDAL library. Currently, the CVS version is being used. |
| 90 |
|
There are no Debian packages available although this may change soon. |
| 91 |
|
A GDAL driver was extended to support writing to memory rather to |
| 92 |
|
files. |
| 93 |
|
|
| 94 |
|
There is still some work that needs to be done, such as some error |
| 95 |
|
handling when loading invalid images or when there is a problem |
| 96 |
|
projecting the image. This putback simply checks in the majority |
| 97 |
|
of the work. |
| 98 |
|
|
| 99 |
|

support classification. |
| 104 |
|
(RasterLayer): New. Defines a new layer that represents an |
| 105 |

* Thuban/Model/map.py (Map.BoundingBox): Fix typo in comment. |
| 114 |
|
|
| 115 |
|
* Thuban/Model/save.py (XMLWriter.encode): Don't assume that we |
| 116 |
|
get a string in Latin1. If we get such as string convert it to |
| 117 |
|
unicode first, otherwise leave if alone before encoding. |
| 118 |
|
(SessionSaver.write_layer): Add support for writing both Layers |
| 119 |
|
and RasterLayers. |
| 120 |
|
|
| 121 |
|
* Thuban/Model/transientdb.py (AutoTransientTable.SimpleQuery): |
| 122 |
|
The right argument may not be a string, it could also be a Column. |

|
|
| 124 |
|
* Thuban/UI/application.py (ThubanApplication.CreateMainWindow): |
| 125 |
|
Make initial window size 600x400. Fixes RTBug #1872. |
| 126 |
|
|
| 127 |
|
* Thuban/UI/classifier.py (Classifier.__init__): Rearrange how |
| 128 |
|
the dialog is constructed so that we can support layers that |
| 129 |
|
do not have classifications. |
| 130 |
|
(Classifier._OnTry): Only build a classification if the layer |
| 131 |
|
supports one. |
| 132 |
|
|
| 133 |
|
* Thuban/UI/legend.py: Change all checks that a layer is an |
| 134 |
|
instance of Layer into checks against BaseLayer. |
| 135 |

| 146 |
|
for rendering RasterLayer layers. |
| 147 |
|

| 148 |
|
the GDALWarp python wrapper and constructs an image from the |
| 149 |
|
data returned. |
| 150 |
|
|
| 151 |
|
* Thuban/UI/tableview.py (LayerTableFrame.__init__): Change the |
| 152 |
|
Choices symbols to match those used in the table query method. |
| 153 |
|
Replace deprecated method calls on table with new method names. |
| 154 |
|
|
| 155 |
|
* Thuban/UI/view.py (MapCanvas.set_view_transform): Try to limit |
| 156 |
|
how small the scale can get. This still needs more testing. |
| 157 |
|
|
| 158 |
|
* extensions/thuban/bmpdataset.cpp: New, but copied from GDAL. |

New. Provides IO routines which write to memory, rather than a file. |
| 163 |
|
|
| 164 |
|
* extensions/thuban/gdalwarp.cpp: New, but basically a direct copy |
| 165 |
|
of the gdalwarp utility provided in GDAL. Added function calls |

| 167 |
|

| 201 |
|
|
| 202 |
|
* Thuban/Model/save.py: Remove some unused imports including the |
| 203 |
|
__future__ import for nested_scopes as Thuban relies on Python 2.2 |
| 204 |
|
now. |
| 205 |
|
(XMLWriter.encode): Remove the special case for a None argument. |
| 206 |
|
In the saver encode is always called with a string argument. |

|
2003-05-16 Bernhard Herzog <[email protected]> |
| 209 |
|
|
| 210 |
|
* Thuban/UI/__init__.py: Remove the work-around for the locale bug |
| 211 |
|
in wxPython (at least when usinvg wxGTK) prior to 2.4. The symptom |
| 212 |
|
of the bug was that e.g. float("1.2") would fail. Thuban now |
| 213 |
|
requires 2.4.x. |
