Textcompression in Delphi 10.1

1. offizieller Beitrag

    Hi,

    There is a property in the ActiveX documentation.

    Property TextCompression
    By modifying this property you can let the PDF engine compress text. By using compression the
    file will be reasonable smaller. On the other had compression will create binary data rather than
    ASCII data. Please note that bitmaps and embedded fonts will be always compressed, either using
    Deflate or JPEG compression.

    With this setting, the size of the pdf document produced in our projects written under .net was reduced by 40%. Is there a way to use this setting from Delphi? I couldn't find any reference to it in the official documentation, neither parameter, nor definition.

    Thanks for the answer!

    The wPDF VCL has these properties which affect the size of the PDF - recommended in bold style

    property CompressStreamMethod: TWPCompressStreamMethod

    wpCompressNone, wpCompressFlate, wpCompressRunlength, wpCompressFastFlate

    property JPEGQuality: TWPJPEGQuality

    wpNoJPEG, wpJPEG_10, wpJPEG_25, wpJPEG_50, wpJPEG_75, wpJPEG_100

    property FontMode: TWPPDFFontMode

    pUseTrueTypeFonts, wpEmbedTrueTypeFonts, wpEmbedSymbolTrueTypeFonts, wpUseBase14Type1Fonts, wpEmbedSubsetTrueType_Charsets, wpEmbedSubsetTrueType_UsedChar

    ,wpEmbedType3 // Build Type3 Subset Fonts

    ,wpEmbedCIDFonts // Shortcut for CID Mode, change everyhing in Fontmode !

    The equivalent for TextCompression is CompressStreamMethod.
