image.has_data can't be called before you load an image, otherwise it will return false even for valid images.
The workaround is to try to run image.glLoad() before. That will crash if the image is corrupted (for we are using try/catch here).
Campbell (ideasman42) thinks it would be better to have an api call proper for that. Since 2.4xx is close to its end I really don't think it's time to keep working in its API. Specially if we have similar functions doing what we need.
@ Arystanbek (kazanbas): I'm done with the obj fixes I told you. You are free to go with the importers :)
You may want to take a look at implementing a proper image.load() to 2.5 as Campbell suggested.
- added export Cameras (ortho and persp) to VPORTs, incl. clipping
- added export Cameras (ortho and persp) to VIEWs, incl. clipping
- export multiple-instances of Mesh-Objects as BLOCK/INSERTs
- on start prints dxfLibrary version
* Wasn't setting the curve 3D option
* The nurbs object name could be None which caused an error, check its set.
OBJ Export
* Off by 1 error on closed nurbs was incorrect, broke other importers but worked with blender.
* Nurbs verts were not adding to the total vert count, scrambling meshes added after (somehow my first test case had all the curve objects last)
Imports nurbs with orderU and endpointU (inferred from weights).
No support for vert-weights, surfaces, 2D curves or non-bspline's yet.
fix for exporting closed nurbs, was overlapping too much of the curve.
If a total of 30 subdirs was hit, or 4 dirs deep was hit - script scanning would quit, skipping files in the root scripts path too.
To work around this the script pack included some of blenders scripts twice just so they would get into the menu but this is a dodgy workaround.
* dont stop scanning for scripts when limits are reached (just dont scan further).
* global 30 dir limit per scan is silly - removed.
* limit recursive depth is kept but keep scanning at lower depths.
* bumped recursive limit from 4 to 6
* flt_properties.py had #!BPY without a menu header.
Adds access to...
- Anisotropy
- Mirr Threshold
- Trans Threshold
Breaks rule of no additions but python data access is quite safe, vray exporter needed these attributes.

- added option for export objects only from visible layers
v1.34 - 2009.06.07 by migius
- cleaning code for release
- fix nasty bug in getExtrusion()

- support XYmirrored 2d-curves to 2dPOLYLINEs
DXF-Library log:
v1.31 - 2009.06.02 by migius
- modif _Entity class: added paperspace,elevation
v1.30 - 2009.05.28 by migius
- bugfix 3dPOLYLINE/POLYFACE: VERTEX needs x,y,z coordinates, index starts with 1 not 0
DXF-Importer: minor changes
DXF-Exporter log:
v1.34 - 2009.06.02 by migius
- support XYmirrored 2d-curves to POLYLINEs: works correct only for rotX,rotY==0.0
- support thickness and elevation for curve-objects
- fix extrusion 210-code (3d orientation vector)
- fix POLYFACE export, synchronized with dxfLibrary.py
- changed to the new 2.49 method Vector.cross()
- output style manager (first try)
v1.33 - 2009.05.25 by migius
- bugfix flipping normals in mirrored mesh-objects
- added UI-Button for future Shadow Generator
- support curve objects in projection-2d mode
- UI stuff: camera selector/manager
- script template use new property syntax
- Python could set the axis/hat to a negative index and crash blender (nobody complained)
- Servo control UI had overlapping text
- CValue warning ShowDeprecationWarning("val = ob.attr", "val = ob['attr']"); had false positives because of python using getattr() internally. Only show the wanring now when a CValue is found.
- Py functions that accepted a vector and a GameObject were slowed down by PySequence_Check() first called on the GameObject, though this would fail it would try and get attributes from the game object - ending up in ~8 attribute lookups each time. Avoiding PySequence_Check() makes ob.getDistanceTo(otherOb) over twice as fast.
- Joystick hat events could crash the BGE for joysticks with more then 4 hats.
- PLY Import failed on PLY files from Carve, added some extra types.
* object_drop.py - option to orient to face normal (useful for scattering objects over terrain), accounts for normal flipping and can adjust the orientation %.
- Fixed some deprecation warnings in documentation.
- Added more conversions to script.
- Added more attributes to script todo list.
- Print out name of text buffer when encountering an error in batch mode.
- Refactor: Simplified attribute map.
- Added notImplemented function to print warnings for missing conversions. References documentation.
Patch from Alex Fraser (z0r)
- All attributes in the conversion map have been checked against the docs. More ambiguities have been resolved.
- Added option to convert all text buffers in Blender.
- Updated GameTypes.py: there were inconsistencies.
The script works well (causes no errors) with 0_FPS_Template.blend and vehicle_demo.blend from the
physics-2.43-physics-testfiles pack.
Caveats:
- Conversions were checked against other deprecated attributes. I may have missed some cases where a deprecated attribute
has the same name as a non-deprecated attribute. I did catch a few though.
- As with the last version, the conversion is purely text-based and doesn't compile the code. It's easy to create a
script that would break on conversion.
Still, it should get you 90% of the way to a converted script.
V2.00 22/05/09 by Aaron Keith
- Better error checking.
- Lock Nut and Hex Nut meshes added.
- Pre-sets for common metric bolts and nuts.
- Improved GUI.
- Meshes scaled to a smaller size
- Fixed bug when using crest and root percent other than 10%
- Can now create meshes in Edit Mode. This will add to the
current mesh and align with the current view.
[#18765] Update of the rvk1_torvk2.py bundled script:
The script has been modified to use the last management of the modifiers in the python api and corrected too. Now it
can copy the mesh object when it is alone and also a shape keys to the second one if needed.
Patch from Roger Wickes update to 2.48 sFrame, eFrame, fps.
[#18794] GE API conversion script: 2.48 -> 2.49
patch from Alex Fraser (z0r), will test further in the next few days.
---
This is text plug in and standalone script that updates Blender 2.48 Game Engine scripts to be compatible with the 2.49
API.
The script contains a mapping of attribute names to functions that do the conversion. Most of the mappings were extracted
from the documentation in GameTypes.py. Where the conversion is ambiguous, the script will not change the source except
to insert a warning as a comment. This means that the script does not completely automate the conversion process, but
will do a lot of the work.
The script still needs a fair bit of testing. Many of the mappings have not been tested and could result in broken scripts.
I'm submitting this patch now to start the review process early. I think I might need help if it is to be included in
2.49.
in 2.48 constant interpolations meant that wasnt a problem but since it now uses linear interp. you can notice errors with animated characters because the 2 eulers are not compatible.
Added optional euler_compat argument to matrix.toEuler(eul) and quat.toEuler(eul) so when getting the euler rotations from a list of matrices the animation curve will be continues.
Also added euler.makeCompatible(euler).
- warning silenced for imagepaint.c
* FBX Bugfix, was exporting all animation curves as 'Constant' type (no docs for this so could only guess), Thanks to Sander Brandenburg for spotting this problem.
Also improved keyframe removal to work on animation curves an angle
