I got the following issues and suggestion from our Japanese customer.
Tested machine: Windows
Scanner: CanoScan LiDE100, CanoScan LiDE200
Issue 1: When scanning the TWAIN driver (ScanGear made by Cannon), OOo freezes
after scanning.
Steps of Issue 1:
1. Install the scanner driver
2. Connect the scanner to the machine
3. Run OOo 3.0
4. Choose [File] [New] [Text Document]
5. Choose [Insert] [Picture] [Scan] [Select Source] and select the scanner
6. Choose [Insert] [Picture] [Scan] [Request]
The scanner driver started.
7. Click the preview button of the scanner driver
The preview image appeared.
8. Click [Scan] button
The image was delivered to OOo.
9. Choose [Insert] [Picture] [Scan] [Request]
The scanner driver started.
10. Click [Scan] button
The image was dellivered to OOo, but OOo freezed.
At this point, the scanner driver already terminated.
Issue 2: When clicking the close button of the TWAIN driver, sometimes the
driver is not closed.
Steps of Issue 2:
1. Install the scanner driver
2. Connect the scanner to the machine
3. Run OOo 3.0
4. Choose [File] [New] [Text Document]
5. Choose [Insert] [Picture] [Scan] [Select Source] and select the scanner
6. Choose [Insert] [Picture] [Scan] [Request]
The scanner driver started.
7. Click the close button of the scanner driver
Sometimes the driver is not closed.
Possible cause of Issue 2 and suggestion:
OOo behavior does not seem to comply with the TWAIN specification.
According to the TWAIN specification, after the application starts the TWAIN
driver,
the application must send MSG_PROCESSEVENT to the driver periodically.
However, OOo does not seem to send MSG_PROCESSEVENT to the driver.
Please see DG_CONTROL/DAT_EVENT/MSG_PROCESSEVENT on page 162 in TWAIN
Specification Version 1.9a
and the sample code on page 28-30 in TWAIN Specification Version 1.9a.
We do not know the cause of Issue 1, but it might be fixed by the above
suggestion of Issue 2.
Could you investigate the suggestion and fix this issue, please?
