[Bug] Pixel arithmetic results in error: Emgu.CV.Util.CvException: OpenCV: 0 <= roi.x && 0 <= roi.width && roi.x + roi.width <= m.cols && 0 <= roi.y && 0 <= roi.height && roi.y + roi.height <= m.rows

Description of the bug

Following error occurs when I try to perform pixel arithmetic operation on multiple layers. It is not consistent, it may occur on different layers of the same file. If I'm lucky enough after 8-10 attempts it completes without error, but sometimes I just give up after 20+ tries: Emgu.CV.Util.CvException: OpenCV: 0 <= roi.x && 0 <= roi.width && roi.x + roi.width <= m.cols && 0 <= roi.y && 0 <= roi.height && roi.y + roi.height <= m.rows at Emgu.CV.CvInvoke.CvErrorHandler(Int32 status, IntPtr funcName, IntPtr errMsg, IntPtr fileName, Int32 line, IntPtr userData) at Emgu.CV.MatInvoke.cveMatCreateFromRect(IntPtr mat, Rectangle& roi) at UVtools.Core.Extensions.EmguExtensions.Roi(Mat mat, Rectangle roi, EmptyRoiBehaviour emptyRoiBehaviour) in UVtools.Core\Extensions\EmguExtensions.cs:line 944 at UVtools.Core.Operations.OperationPixelArithmetic.<>cDisplayClass149_0.b0(Int64 layerIndex) in UVtools.Core\Operations\OperationPixelArithmetic.cs:line 924 at System.Threading.Tasks.Parallel.<>cDisplayClass20_0`1.b1(RangeWorker& currentWorker, Int32 timeout, Boolean& replicationDelegateYieldedBeforeCompletion) --- End of stack trace from previous location --- at System.Threading.Tasks.Parallel.<>c__DisplayClass20_0`1.b__1(RangeWorker& currentWorker, Int32 timeout, Boolean& replicationDelegateYieldedBeforeCompletion) at System.Threading.Tasks.TaskReplicator.Replica.Execute()

How to reproduce

Go to "Tools" -> "Pixel Arithmethic"
Make sure layer range is set to all layers
Set Operator: Subtract with brightness
Set Apply to: Model surface
Set brightness: Use a pattern instead of fixed brightness
Set Alternate pattern every "1" layers
Set pattern to: 0 32 32 0
Set alternate pattern to: 32 0 0 32
Click "Pixel arithmetic" button to start operation
Result: Error should occur

This is the same as https://github.com/sn4k3/UVtools/issues/905 I also cannot reproduce using your workflow. Can you provide the file? Does it happen every time to you?

Drynwhyl commented 2 weeks ago

It happens almost every time with large file (2000-3000 layers). If it's something small (around 300-500 layers) it can work first try. Here is the file link: https://drive.google.com/file/d/1q6aH6RXziXLpUuh7nYFL_CXULw_LoCrW/view?usp=sharing

Tested with your file and it works fine, I ran 5 times the operation without errors. Need to dig into this and see if I can spot the problem
