Obsolete commands

Some QPix commands have become obsolete in QPix v3. This is mainly because there is new fuctionality in QPix v3 that achieves the same or better result.

The obsolete commands have the QPxObs_ prefix in their names. Note that you don't have to do any changes to your 4D code if you have been using these commands. The command names in your methods are updated automatically, and the obsolete commands continue to function as before. However, you are strongly advised to update your code to use the new commands in QPix v3. The obsolete commands will be removed from the plug-in in the next major update.

The obsolete commands are:

QPx_GetTWAINVersion, QPx_GetTWAINSources, QPx_AcquirePicture
Image acquisition is now handled by the commands in the new acquisition module.
QPx_GetImageFileMetaData , QPx_GetImporterMetaData , QPx_GetImporterMetaDataItem
Image metadata is now handled with the tag commands.
QPx_GetImageFileThumbnail, QPx_GetPictureThumbnail, QPx_GetImporterImageThumb
There are new commands that create high quality thumbnails:
QPx_SetImporterQuality, QPx_GetImporterQuality, QPx_SetImporterGraphicsMode, QPx_GetImporterGraphicsMode
Importer quality and graphics mode are now handled by the plug-in internally.
QPx_RedrawArea
It is no longer necessary to call this command.
