Troubleshooting

Problem	Solution
The window of Run.bat closes immediately	Add pause as the last line of the batch file to read the messages.
ImgScan cannot find its helper programs, or reports Internal process was failed	Start ImgScan from the ImgScan folder: add cd /d "%~dp0" at the start of the batch file.
A path with spaces does not work	Move the image, the output folder or the ImgScan folder to a path without spaces.
A TIFF image cannot be read	Not every TIFF variant is supported. Save the image as an uncompressed 8-bit .bmp.
A failed run is reported as a success	The batch file tests if errorlevel 1. Use if %errorlevel% neq 0; see exit codes.
Thin lines are missing in the result	Adjust THRESH and lower TRASHNUM; see choosing the parameters.
The result is too large or too small	Set PIXEL to the real pixel size of the image.
The run is slow	Close other programs, keep %TEMP% on a fast local drive, and do not run more conversions at once than the computer can hold.
The disk fills up	Each run needs free space in %TEMP% of about ten times the size of the image. Delete IMGSCAN_* folders left behind by DEBUG runs or by a crash.
ODB++ export stops with exit code 1028	Move the ImgScan folder closer to the root of the drive; see path rules.
