Would love to see some sort of better graphics support to allow flicker
free graphic transitions, such as for changing out images etc....

I'm not looking for gaming quality graphics support, but at least for say
skinning purposes.

Maybe also support for JPG, PNG and GIF image files, so that you don't always need to "run around" with big BMP files? Smile

I've developed an IMAGE dialog element that supports all the popular image file types, and 127 different transition effects. It will be in an external DLL, so the runtime won't be bloated out with all the code needed to understand the different image formats. For skins, however, you'll still need to use the standard BITMAP element if you want parts of the window to be invisible. It's not possible to combine all this functionality into one dialog element.

Jules - any support for PDF or multi-page TIFF in the extension?

The library I used doesn't support PDF, only bitmap image formats. TIF is supported, but I don't know if multi-page - it might say in the docs somewhere, but I don't have such a file to test it with.

Jules: attached is a zipped multi-page TIF file if you want to test the element.

Jules,
To read that Tiff file your Image element would have to handle a Tiff file with multiple layers. Each layer is a seperate page in the Tiff file. Joe sorry I have not sent you the OCR example yet.

Yep. There are probably very few image libraries that handle all the possible TIFF options. Probably to handle this we would need to use one that specialised in TIFF at the expense of support for other image types.

That could be, but all 3rd-party programs that I use seem to support all versions of TIFFs, if they support any at all. The only ones that seem to be not widely supported are the ones using "lossless compression" - LZW I think it is called.

I know the IMAGE element will be a great addition to VDS. It would be nice if there was multi-page TIFF support, though. It is a popular "document management" format - Microsoft uses it in their recently released Office Document Imaging.

Currently I have an app that allows the user to view TIFFs. I am using the GraphicsMagick program to convert each page to a bitmap and then I display the bitmap on a VDS dialog. It works pretty well, just faster to do it natively.

There are certainly libraries that can do it, unfortunately various practical considerations limit the ones we can use in VDS. The main problem with commercial libraries is that the license agreement only covers use in an application, not as a redistributable component in a developer tool like VDS. If they were to agree to it, likelihood is they would want 200 bucks or whatever the license fee is per copy of the extension. A lot of ideas for extensions have got nowhere because of this.
