Hello,
it seems, that the all questions regarding the future of TWAIN are completely unanswered in this list. Judging from the activities in the past, I start to think, that we can consider TWAIN to be a dead standard.
This is a real pitty regarding the development of drivers and the involvement of big companies like Fuji, Kodak, Ricoh, Adobe and others.
WIA has been proposed from Mircosoft as the future standard for image acquistion. But this API is completely architectured for the normal average user, who wants to get some boring images from his boring photo mobile.
Hello EPSON, what about your future plans to support your top end scanner models like GT-30000 with ADF in Windows Vista?
We have used the twain standard in the past in order to interface special types of industrial scanners and made use of some custom capabilities. We do not see a way to map this functionality into the new WIA API. There is no concpet of an “My Images folder” or other fancy goodies. For example WIA does not have an equivalent for the transfer mode. We transport images of roughly 1GB data for one image via the twain interface and need this mode in order to start some examinations with the already scanned data. In addition we are thinking about a direct transfer of CIELab image data instead of RGB. This is not possible with WIA.
All this makes me really angry. Again the users of a standard are left alone between the stagnating evolution of the standard and the mighty Microsoft monopole that dictates a new proprietary non inapplicabable API.
In order to support our TWAIN driver in win64 we already wrote our own lightweight Twain64 data source manager.
Is there no one of the official TWAIN representatives on this list, that can shed any light onto the future of TWAIN?
Does anybody have an advice on how to proceed in the future:
* On the one hand we have a working solution with TWAIN, but we need to support 64bit in order to make use of the larger address space. But TWAIN is not supported in this environment And it seems, that there will be no support of TWAIN in the future of windows.
* On the other hand there is WIA, which doesn’t fit into the needs of advanced access with automatic acquisition of industrial scanning devices.
* ISIS is no solution either.
When will the proposed TWAIN 2.0 standard with the proposed 64bit DSM be released? The draft is dated from the 28.11.2005?
If the data source will be released with a Open Source license, why don’t you make it public?
I’m really looking for an answer. Please any of the officials, take the time and write up some statement what you plan for the future.
Best regards
Dirk LuethjensHi –
I can’t offer any advice when it comes to the updated DSM or any of that, but at least on 32bit Vista, our (XP tested) TWAIN driver seems to be pretty complete without any modifications.The only problem I seem to have is the use of the .INI file in the TWAIN_32myscanner directory. I’m not sure, but my guess is that the new security requirements of Vista prevent an application running in normal user mode (no administrator privileges) from writing into files under the Windows directory. I’m not sure what I’ll do to store the dialog pre-sets we’re using as registry access is limited too. If anyone has any ideas, I’m all ears.
good luck,
