Failure symptoms
An incompatible image can produce the following message in the Visionscape debug window:
Failed to Read Image File: The file c:\...tif is either missing or corrupt.The same condition can also crash the Visionscape software. The message does not distinguish among a missing file, a corrupt file, and an incompatible TIFF format, so verify each condition before retrying.
Required TIFF format
| Requirement | Required value |
|---|---|
| File type | TIFF image |
| Compression | Uncompressed |
| Color depth | 8-bit |
Changing only the filename extension to .tif does not establish that the image meets these internal format requirements.
Resolution procedure
- Confirm that the image exists at the file path reported in the debug message and is not corrupt.
- Confirm that the file is an uncompressed TIFF image with 8-bit color depth.
- If format compatibility remains uncertain, save the image from Visionscape software. Visionscape-generated image files are automatically stored in the required format.
- Run the image again in Visionscape FrontRunner.
Verification
Verify that the image runs without the Failed to Read Image File message and without a Visionscape software crash. If the failure remains, recheck the reported path and determine whether the file is missing or corrupt before treating the issue as a format problem.
FAQ
What TIFF format does Visionscape FrontRunner require?
Use an uncompressed TIFF image with 8-bit color depth.
Why does Visionscape say my TIFF file is missing or corrupt?
The message can indicate a missing or corrupt file, but an incorrectly formatted image can also trigger it. Verify the path, file integrity, uncompressed TIFF format, and 8-bit color depth.
How can I create a compatible Visionscape image file?
Save the image from Visionscape software. Files saved by Visionscape are automatically written in the required format.
