i'm using Leadtools SDK to drive a Canon 9050C with Leadtools SDK v17.

It works great in black and white with autodetection of page format.
But in color, for full speed scanning, i have to force paper format 'A4 landscape'.

So I save the template with the  'SaveTemplateFile' and it works.
But when I reload this template with 'LoadTemplatefile' the paper format has changed, and is set to 'A4'.

Is there a solution to force the paper format to keep as selected when saved ?

Thank you.

Can you test the same issue using the Twacker utility from the Twain Working Group? If you don't have Twacker, you can obtain it by using the following link:

You can test it as follows:
1. Run the Twacker utility.
2. From File menu, select "Select Source", and select the Canon 9050C.
3. From Special menu, select Load/Open SM.
4. From Special menu, select Open Source.
5. From Special menu, select Send.
6. In the MSG field, select MSG_SET.
7. In the capability field, select ICAP_ORIENTATION.
8. In the Value field, select the TWOR_PORTRAIT, and press Send, and then press Close.
9. From Special menu, select Close/Unload SM.
10. Repeat the steps from 3 to 7, but instead of MSG_SET, select MSG_GET.
11. Press on Send, and see the returned value.

Do the same test, but instead of TWOR_PORTRAIT, use TWOR_LANDSCAPE.

Does it work without any failure? What is the returned value for each test?
