|
* Thuban/UI/baserenderer.py (proj_params_to_str): New. Takes |
| 4 |
|
a projection and returns a formatted string representing the |
| 5 |
|
parameters to feed to gdalwarp. This function eliminates |
| 6 |
|
redundancy in draw_raster_layer(). |
| 7 |
|
(render_map_incrementally): Removed the optimization which |
| 8 |
|
drew the top most raster layer first and then only those vector- |
| 9 |
|
based layers that are above it. With the support for transparency |
| 10 |
|
this optimization breaks correct behaviour. |
| 11 |
|
(draw_raster_layer): Reorganize code to support possible future |
| 12 |
|
enhancements to raster layer bounding box. The old behaviour has not |
| 13 |
|
changed. Also, change calling parameters to draw_raster_data() |
| 14 |
|
to specify new RAW data format and mask. |
| 15 |
|
(draw_raster_data): Change signature to include an optional |
| 16 |
|
parameter for mask information. Change documentation to mention |
| 17 |
|
support for new parameter and added option for RAW data format. |
| 18 |
|
The data argument is now a list of [width, height, data]. |
| 19 |
|
|
| 20 |
|
* Thuban/UI/renderer.py (draw_raster_data): Add new optional |
| 21 |
|
mask parameter. Add new condition for RAW format, which |
| 22 |
|
significantly reduces rendering time. Add condition for |
| 23 |
|
mask parameter. |
| 24 |
|
|
| 25 |
|
* libraries/thuban/gdalwarp.cpp (GetImageData): New. Creates a |
| 26 |
|
data array of RGB values from the projected image returned from |
| 27 |
|
the gdal warping functions. In the case of palette based images, it |
| 28 |
|
converts the NO_DATA index to the mask color. |
| 29 |
|
(ProjectRasterFile): Removed all custom memory driver references |
| 30 |
|
and replaced it with the standard in-memory dataset provided |
| 31 |
|
by gdal. The return data is no longer a BMP file, but an array |
| 32 |
|
of RGB values, one set triple per pixel. |
| 33 |
|
|
| 34 |
|
* libraries/thuban/bmpdataset.cpp: Removed. Unnecessary. |
| 35 |
|
* libraries/thuban/cpl_mfile.h: Removed. Unnecessary. |
| 36 |
|
* libraries/thuban/cpl_mfile.cpp: Removed. Unnecessary. |
| 37 |
|
|
| 38 |
|
* setup.py (thuban_build_ext.finalize_options): Removed mention |
| 39 |
|
of cpl_mfile.cpp and bmpdataset.cpp files in the list of source |
| 40 |
|
files. These are obsolete with the new version of gdalwarp.cpp |
| 41 |
|
|
| 42 |
|
* test/test_baserenderer.py (draw_raster_data): Updated signature. |
| 43 |
|
(test_raster_no_projection): Changed the test data to be data |
| 44 |
|
in the uncompressed RAW format returned from ProjectRasterFile. |

* Thuban/UI/mainwindow.py (view_position_changed): Made string |
| 49 |
|
available for i18n. |

|
* Resources/Projections/defaults.proj: Ruin the speling of the |
| 54 |
|
Lambert-93 projection so it doesn't run into the wx UTF-8 bug. |
| 55 |
|
It's the wrong thing to do in the long run, but it's necessary for |
| 56 |
|
those users until that bug is fixed. Otherwise the projection |
| 57 |
|
dialog segfaults. Better to annoy some Lambert-93 users with a |
| 58 |
|
spelling mistake than every Fedora Core 3 user of Thuban-CVS. |

* Thuban/UI/mainwindow.py(view_position_changed): Added docstring |
| 63 |

and comment that the warning code here is a hack. |

misprojected layers when their lat/lon bounding |
| 69 |

box exceeds rational lat/lon values. |
