Initial putback of projection management code. Includes new |
| 4 |
|
classes to read and write projection files. The current load |
| 5 |
|
and save classes were abstracted a bit so they could be reused. |
| 6 |
|
The Projection class was extended to provide new methods and |
| 7 |
|
have a name. |
| 8 |
|
|
| 9 |
|
* Thuban/Model/load.py (XMLProcessor): New. Contains all the |
| 10 |
|
general XML reading methods that were part of ProcessSession. |
| 11 |
|
|
| 12 |
|
* Thuban/Model/proj.py (Projection.__init__): Accepts an optional |
| 13 |
|
name. |
| 14 |
|
(ProjFile): New. Represents a file that contains projection |
| 15 |
|
information. |
| 16 |
|
|
| 17 |
|
* Thuban/Model/resource.py: New. Contains general utilities |
| 18 |
|
for read and writing projection files. |
| 19 |
|
|
| 20 |
|
* Thuban/Model/save.py (XMLSaver): New. Contains all the |
| 21 |
|
general XML writing methods that were part of SessionSaver. |
| 22 |
|
(SessionSaver): Renamed from Saver. |
| 23 |
|
|
| 24 |
|
* test/test_proj.py: New test cases for the projection |
| 25 |
|
file read and write functions. |
| 26 |

| 28 |
|
|
| 29 |
|
* Thuban/Model/classification.py: Use repr() around values |
| 30 |
|
in the ClassGroup*.__repr__() methods so it is clearer when |
| 31 |
|
a value is a string and when it is a number. |
| 32 |
|
|
| 33 |
|
* test/test_load.py: Rework the classification test to test |
| 34 |
|
that we can load old files. |
| 35 |
|
(testLabels): Test a file where the groups have labels. |
| 36 |

|
Safer implementation of the performance enhancements of the |
| 40 |
|
low-level renderer: |
| 41 |
|
|
| 42 |
|
* extensions/thuban/wxproj.cpp (extract_projection) |
| 43 |
|
(extract_pointer): Rename extract_projection to extract_pointer |
| 44 |
|
and redefine its purpose to return the pointer stored in a CObject |
| 45 |
|
returned by the object's cobject method. Update all callers. |
| 46 |
|
(s_draw_info, free_draw_info, draw_polygon_init): Implement the |
| 47 |
|
handling of these low-level parameters so that each s_draw_info |
| 48 |
|
instance is handled as a CObject at python level that also |
| 49 |
|
contains real references to the actual python objects which |
| 50 |
|
contain the values in the struct. Add free_draw_info as the |
| 51 |
|
destructor. |
| 52 |
|
(draw_polygon_shape): Add the py_draw_info parameter which must a |
| 53 |
|
cobject containing an s_draw_info pointer. |
| 54 |
|
|
| 55 |
|
* Thuban/UI/renderer.py (MapRenderer.polygon_render_param): New |
| 56 |
|
method to instantiat the low-level render parameter |
| 57 |
|
(MapRenderer.draw_shape_layer): Use the new method. Remove some |
| 58 |
|
commented out code. |
| 59 |
|
(MapRenderer.draw_polygon_shape): Make the first parameter not the |
| 60 |
|
layer but the low-level render parameter |
| 61 |
|
(ScreenRenderer.draw_shape_layer): Use the low-level render |
| 62 |
|
parameter. |

|
|
| 66 |
|
* Thuban/Model/classification.py: Implemented __repr__ for |
| 67 |
|
the ClassGroup* classes to make debugging a bit easier. |
| 68 |
|
(ClassGroup.SetLabel): Check that the string is an instance |
| 69 |
|
of StringTypes not StringType. Accounts for Unicode strings. |
| 70 |
|
|
| 71 |
|
* Thuban/Model/color.py: Implemented __repr__ to make |
| 72 |
|
debugging a bit easier. |
| 73 |
|
|
| 74 |
|
* Thuban/Model/save.py (Saver.write_classification): Need to |
| 75 |
|
save the group label. |
| 76 |
|
|
| 77 |
|
* test/test_load.py (testClassification): New. Loads the |
| 78 |
|
iceland_sample_test.thuban file and checks if it was loaded |
| 79 |
|
correctly. |
