How do I get available sub types for a RasterSaveDialogFileFormat?

I am using the FastTwainDemo to put together an application that imports from a twain device and saves into our document file structure. I need to make available to the users an options dialog similar to the RasterSaveDialog, but without the Save As file field because the users will not be able to pick a path in my application. So I have created my own options controls, but I am falling short on a couple areas. I can use this to get a list of available formats:

RasterSaveDialogFileFormatsList _rasterFormatList = new RasterSaveDialogFileFormatsList(RasterDialogFileFormatDataContent.Default);

But I need ot be able to get the sub types for each type so I can make them available for selection. How do I do this? Also, what is the allowed qfactor for each type? I can see how to get the BitsPerPixelList and the default.

I guess another option form me would be if there is a way to make the built in save dialog not show the file path.

Thanks for any help,

Glenn

Are you looking to support a lot of file types through your dialog or just a select few with the different sub types? The sub-types are enumerated in the Leadtools.WinForms.CommonDialogs.File namespace.

Using RasterSaveDialogFileFormatsList will allow you to create a list of formats. Have you looked at the RasterSaveDialogFileFormat class? You can declare a file format to be of a specific type, i.e. RasterDialogFileTypesIndex.Tiff

I would also suggest checking out the topic "Compression Quality Factors" in the documentation. This should help with your issues with qFactor.

Thanks for the response. I found what I needed the following way:

My list of available types case from:
RasterSaveDialogFileFormatsList _rasterFormatList = new RasterSaveDialogFileFormatsList(RasterDialogFileFormatDataContent.Default);

From a specific type I could get the available BitsPerPixel from:
_rasterFormatList[i].BitsPerPixelList


For a specific BitsPerPixelList, I can get the subtype like this:
format.BitsPerPixelList[_cmbBitsPerPixel.SelectedIndex].SubFormatsList[i].Name
