Converting Preview Files to Other Formats

Knowledgebase English KB

Valid from List & Label 10
Starting with version 10, List & Label offers you the possibility to convert preview files to other formats. To do so, use the APIs LlStgsysConvert() and LlStgsysStorageConvert(). Most of the components offer a very comfortable wrapper for the Stgsys API interface.

General: 
LlStgsysStorageConvert("...\preview.ll", "...\preview.pdf", "PDF")


The first parameter is the source file, the second is the target file and the third is the required target format. Valid formats are “TTY”, “PDF” and “PICTURE_MULTITIFF”. Additional Parameters can be passed as semicolon separated list:

LlStgsysStorageConvert("...\preview.ll", "...\preview.pdf", "PDF;PDF.Encryption.EncryptFile=1")


For Delphi (xx = version):

var PrvFile: TLlxxPreviewFile;

begin
    PrvFile:=TLlxxPreviewFile.Create('...\preview.ll', true);
    PrvFile.ConvertTo('...\preview.pdf', 'PDF');
    PrvFile.free;
end;


For .NET (here C#):

PreviewFile pf = new PreviewFile(@"...\preview.ll");
pf.ConvertTo(@"...\\preview.pdf","PDF");
