This puts back Raster layer support. These layers support projections |
| 4 |
|
through the GDAL library. Currently, the CVS version is being used. |
| 5 |
|
There are no Debian packages available although this may change soon. |
| 6 |
|
A GDAL driver was extended to support writing to memory rather to |
| 7 |
|
files. |
| 8 |
|
|
| 9 |
|
There is still some work that needs to be done, such as some error |
| 10 |
|
handling when loading invalid images or when there is a problem |
| 11 |
|
projecting the image. This putback simply checks in the majority |
| 12 |
|
of the work. |
| 13 |
|
|
| 14 |
|
* setup.py: Add gdalwarp library extension. |
| 15 |
|
|
| 16 |
|

|
| 30 |
|

| 34 |
|
and RasterLayers. |
| 35 |
|
|
| 36 |
|
* Thuban/Model/transientdb.py (AutoTransientTable.SimpleQuery): |

|
| 42 |
|
* Thuban/UI/classifier.py (Classifier.__init__): Rearrange how |
| 43 |

the dialog is constructed so that we can support layers that |
| 44 |
|
do not have classifications. |
| 45 |
|
(Classifier._OnTry): Only build a classification if the layer |
| 46 |
|
supports one. |
| 47 |
|
|
| 48 |
|
* Thuban/UI/legend.py: Change all checks that a layer is an |
| 49 |
|
instance of Layer into checks against BaseLayer. |

| 64 |
|
data returned. |

| 68 |
|
Replace deprecated method calls on table with new method names. |
| 69 |
|
|
| 70 |
|
* Thuban/UI/view.py (MapCanvas.set_view_transform): Try to limit |
| 71 |
|
how small the scale can get. This still needs more testing. |
| 72 |
|
|
| 73 |
|
* extensions/thuban/bmpdataset.cpp: New, but copied from GDAL. |

| 116 |
|
|
| 117 |
|
* Thuban/Model/save.py: Remove some unused imports including the |
| 118 |
|
__future__ import for nested_scopes as Thuban relies on Python 2.2 |
| 119 |
|
now. |
| 120 |
|
(XMLWriter.encode): Remove the special case for a None argument. |
| 121 |
|

|
2003-05-16 Bernhard Herzog <[email protected]> |
| 124 |
|

| 125 |
|
* Thuban/UI/__init__.py: Remove the work-around for the locale bug |
| 126 |
|
in wxPython (at least when usinvg wxGTK) prior to 2.4. The symptom |
| 127 |
|
of the bug was that e.g. float("1.2") would fail. Thuban now |
| 128 |
|
requires 2.4.x. |
