Adjust airmap logic during 2nd pass to account for contours that were determined to be air-connected during first pass.
Always move resolved resin traps to suction traps, and only conditionally report them as issues if configured to do so. Suction traps are used during a cleanup stage for resin traps, so needs to be populated no matter what, there is no additional processing penalty for this.
The following is a novel implementation of resin/suction trap detection for MSLA sliced images It largely consists of 2 passes through the layers.
The 1st pass processes the layers from the bottom to the top, keeping track of what areas in the previous layer are air (or connected to air in some way). The initial air map is derived from the starting layer, by inverting the layer and then filling all external contours black (not air) which results in an inital air map of everything that is not solid, or inside a solid, being considered air. While traversing the layers, the air map is updated to include any new air regions, or hollow areas that intersect with the air map (since while they are not air, they are connected to air). Any regions that do not overlap the air map are declared resin traps.
The 2nd pass processes the layers from the top to the bottom, the initial air map differs from the 1st pass. For the 2nd pass, anything that is not solid is considered to be air (a bitwise not of the top layer is used). The airmap is updated per layer just like it was in the 1st pass, however we do not test all contours of the layer, only those that were marked as resin traps by the 1st pass. This is acceptable because in the event we did test all hollow areas, and one of those was *not* detected on 1st pass, it must be air-accessible from the bottom. In the even that a contour we are testing does overlap the air map during the 2nd pass, it is cleared from the "resin trap" list and instead added to the "suction trap" list. This is to indicate that while there is access to air from the top, there are regions that could be affected by vacuum/suction forces during the print
- (Add) Allow to choose custom locations for "Send to"
- (Improvement) Better random generation for benchmark
- (Fix) Outline - Hollow areas: Not outlining the second closing contour for contours with child

- (Fix) Light-off delay fields was not hidding when set a mode that dont require the extra time fields
- **Exposure time finder:**
- (Fix) Fix the 'light-off delay' field not being show on files that support wait time before cure
- (Change) Field name 'Light-off delay' to 'Wait time before cure'
- (Add) Fade exposure time: The double exposure method clones the selected layer range and print the same layer twice with different exposure times and strategies
- (Add) Double exposure: The double exposure method clones the selected layer range and print the same layer twice with different exposure times and strategies
- (Add) Clone layers: Option to keep the same z position for the cloned layers instead of rebuild model height
- (Improvement) The layer range selector for normal and bottom layers now selects the correct range based on IsBottom property rather than layer index
- (Fix) The layer range selector was setting a very high last layer index when bottom layer count is 0
- (Fix) Pixel arithmetic: Threshold types "Otsu" and "Triangle" are flags to combine with other types, it will auto append the "Binnary" type
- (Add) Support for Encrypted CTB (read-only)
- (Add) Setting - Max degree of parallelism: Sets the maximum number of concurrent tasks/threads/operations enabled to run by parallel method calls.
If your computer lags and freeze during operations you can reduce this number to reduce the workload and keep some cores available to other tasks as well.
<= 0: Will utilize however many threads the underlying scheduler provides, mostly this is the processor count.
1: Single thread. (#279)
- (Fix) On some tools, calibration tests and even files when recalculating the Z layer position for the whole set, it will use the bottom setting for all layers
- **Tool - Dynamic Layer Height:**
- (Add) Option to strip anti-aliasing: Use this option if you get flashy layers or if you want to enhancement the results
- (Add) Option to reconstruct anti-aliasing: Use this option with "Strip anti-aliasing" to reconstruct the layer anti-aliasing via an gaussian blur
- (Add) Maximum wide difference: The maximum number of pixels wide difference to be able to stack layers, where one pixel difference is a whole perimeter of the object to be eroded.
0 = Stack only equal layers
n = Stack equal layers or with a n perimeter of difference between the sum of the stack (#274)
- (Add) Allow to change the base exposure times for the auto generation (#274)

- (Fix) Recalculate the material milliliters per layer when replacing a layer collection (#273)
- **(Fix) Layers:**
- Round properties before comparing to avoid the precision error
- Prevent 'Wait time' properties from having negative values
- The `RetractSpeed` or `RetractSpeed2` property wasn't setting the bottom speed for bottom layers, instead the normal retract speed was always used
- Set the `RetractHeight2` or `RetractSpeed2` property was not notifing the timer to update the print time no
- Propagate global settings to layers now identfies the bottom layers per height instead of layer index
- (Add) UVJ: Support TSMC for the file format
- (Fix) UVJ: Soft save was not updating the layer settings
- (Fix) CTB: TSMC not working properly due incorrect layer `LiftHeight` value calculation

- (Change) Software version field to 1.9.0
- (Fix) Bottom layer count field was not being set in one of the tables
- (Fix) CXDLP: Force the 'Wait time before cure' to be 1 as minimum, or else 0 is preventing the print

- BottomWaitAfterLift -> BottomWaitTimeAfterLift
- WaitAfterLift -> WaitTimeAfterLift
