MBS( "Container.Export"; Container; Index or Type; FilePath )


Parameter Description Example value
Container The container where the data is stored.

Writes selected data content from a container to a file path.
For example you can write out from a TIFF image stored in the database the TIFF data itself or the preview JPEG.
Please note that types are always 4 characters long, "PDF " has a space on the end.
Some of the allowed types include "TIFF", "PDF ", "PNGf", "GIFf", "BMPf", "EPS ", "PICT", "M4V ", "WAV ", "M4A ", "MOV ", "AVI ", "AU ", "MP3 ", "MPEG", "MPG4", "AIFF", "8BPS", "FILE", "MAIN", "JPEG" and maybe some more.

To convert image formats, please review GraphicsMagick functions like GMImage.NewFromContainer and GMImage.WriteToPNGContainer.
To convert PDF to PNG, check functions like PDFKit.GetPDFPageImage, DynaPDF.GeneratePreview or DynaPDF.RenderPage.

This function is only for internal containers. Please use Container.WriteFile for all containers.

This function requires a native path. Use Path.FileMakerPathToNativePath to convert a FileMaker path to a native path if required. If you like to have the user choose the path, you can use FileDialog functions.
For Server be aware that server has limited permissions and may not be able to access all files on a computer.


Export JPEG file:

MBS("Container.Export"; Files::data; "JPEG"; GetAsText(Files::data)+".jpg")

Export all streams in container to individual files:

Set Variable [$container; Value:Test::Image]
#where to save
Set Variable [$DesktopFolder; Value:MBS("Folders.UserDesktop")]
#loop over streams in container
Set Variable [$count; Value:MBS( "Container.GetCount"; $container )]
Set Variable [$index; Value:0]
    #query the type of stream with given index
    Set Variable [$type; Value:MBS( "Container.GetType"; $container; $index )]
    #write it to a file
    Set Variable [$path; Value:$DesktopFolder & "/" & $type]
    Set Variable [$r; Value:MBS( "Container.Export"; $container; $index; $path )]
    Set Variable [$index; Value:$index + 1]
    Exit Loop If [$count = $index]
End Loop
