Troubleshooting Tips

Problem Solution
The component cannot process file and the Status Monitor gives the following error message:

"Cannot load stamp values: No Data"

Check that your machine is connected to local net.
The component cannot process file and the Status Monitor gives the following error message:

"Cannot load stamp values: Host not found"

Check that your Bates Stamp Server login options (server IP or host name and interaction port) are correctly specified.
The component cannot process file and the Status Monitor gives the following error message:

"Cannot load stamp values: Authentication error: invalid certificate"

Check that the certificate file is present and valid (not expired).
The component cannot process file and the Status Monitor gives the following error message:

"Cannot save stamp, group or user (administration)."

  • This can happen if connection with the web service is lost. Check that the web service is started on server machine. Check that you can connect to the server machine.
  • Stamps, groups and users, which contain incorrect data, cannot be saved. Check the settings and correct them if necessary.
The following message will appear when you are trying to save the configuration:

"Cannot save configuration."

This happens if configuration contains incorrect data. Verify all settings of the component.
The following error message is displayed:

"Invalid stamping area."

This error appears in the following cases:
  • For Predefined position, margin values make stamp area incorrect;
  • In Shrink and apply mode, margin values require image resizing to less than 25% of original size.
The following error message is displayed:

"Stamping area is too small."

This error occurs if the stamping area is too small in height to enclose the minimum acceptable part of a stamp (in current version, this value is 50% of stamp height).
The following error message is displayed:

"Stamping area is too narrow."

This error occurs if the stamping area is too small in width even to enclose one symbol of the stamp.
The component changes PDF image colors when processing/previewing/selecting stamp zones. This may happen if the Color depth parameter is not set to 24 BPP. Try to set 24 BPP color depth when processing the document or previewing/selecting stamp zone. If the generated stamped image has a big size, configure the Compression type parameter to compress the image.
The colors of PDF image with 24 BPP color depth may also change a little, as the LeadTools™ fades such images slightly. This effect is especially visible when an image is processed in a cycle for several times.
When processing 4-bit TIFF images, the component can produce the stamps of an incorrect color. This may happen if the palette in the image does not include the color specified for the stamps. The component chooses the image palette color that is closest to the specified one. Use images with higher color-depth if you want to preserve the original color.
