Re: CreateClonedGdPictureImageI Bug

Sorry, but I still have GP8.
What was the latest version on 8? Can I get a download link?
We have no plans to upgrade to 9 for now.

CreateClonedGdPictureImageI Bug

Hi,

When I use CreateClonedGdPictureImageI on a grayscale image it results in a yellowish image. Is there something wrong with that method?
Attached are sample and result images.

FormDropOut InvalidParameter

Hi,

I'm trying to use the FormDropOut method. I even tried the same code sample that's in the Reference Guide, but in C#.
But I always get InvalidParameter as a result. I know the images are ok.
What can I be doing wrong?

Re: TwainShowSetupDialogSource()

Hi,

Currently I'm using a Canon DR-3010C.
But anyway, I'll try not to rely my app on this behavior. Thanks.

Re: TwainShowSetupDialogSource()

Hi,

It seems to me that it returns true whether I press cancel or ok.
Is there anyway to know which one has been pressed?

Can't display page from Multipage

Hi, It seems that when a new page(s) is added to a multipage document and it is already attached to a GdViewer object the added page(s) cannot be selected until another page that previously existed is selected. This only happens when the page(s) are added at the end of the document, at index 1 or be...

Re: TiffGetPageCount returns 0 on single page readonly tifs

Hi,

I know it's easy to work around this. But I still think it's not the best approach, it should return 1.
Anyway, thanks for the quick answer.

Is this an issue? Before loading I have no other way to know if this is a single page tif, opening for write ...

Re: Custom Capabilities in TWAIN

Never thought that cast would even work as the values are not predefined, but it does! :D
Sorry I didn't even tried before, hehehehe. :oops:
Thanks a lot.

Re: Custom Capabilities in TWAIN

Can you provide a more extensive sample? I'm using c# and I can't send integers to TwainSetCapCurrentNumeric, only a TwainCabalities enumeration value. Is there some special way in which I should reference the library?
