* Fix scaling for fan/strip projectorWillem Jan Palenstijn2019-03-292-9/+72
| | | | | | | | | | | | The strip model for a fan beam geometry wasn't taking pixel magnification into account. Among other things, this resulted in diagonals through rectangles being weighted the same as hor/ver lines. This commit fixes this by scaling each pixel contribution by its magnification on the detector. This is only an approximation (since the magnification isn't constant inside the pixel), but since pixels are usually small, the error is also small. Unfortunately, computing this scaling factor is relatively expensive because it introduces a square root in the inner loop.

* Flip wrong detector orientation for fan2d_stripWillem Jan Palenstijn2019-03-231-2/+2
| | | | | | There are still some remaining fan2d_strip unit test failures, with suspicious slightly too large numerical deviations around 45 degree projections.

* Fix rounding error in ParStripProjector2D::getProjectionWeightsCountWillem Jan Palenstijn2019-03-121-2/+2
| | | | | | | | | In the worst case this would lead to (nearly) empty storage for getMatrix(), resulting in (near) explicit projection matrices. (These are only used for exporting explicit sparse projection matrices to matlab/python; not for FP/BP/reconstruction.) This is a quick fix; ideally the affected code would use dynamic storage.

|/ | | | | | | Since these settings are optional, they should have been in cfg.options instead of directly in cfg. The old syntax remains a fallback. This has the side-effect that the tomopy/astra interface can also supply them.
