AddImageJBIG2FromString

Image handling

Description

Loads bitmap bytes from an AnsiString, converts them to a monochrome image, applies optional scan cleanup, and stores them as a JBIG2 image XObject

Function TPDFlib.AddImageJBIG2FromString(Const Source: AnsiString; Options, BlackDotSize, LossyLevel: Integer): Integer;

Source	Bitmap bytes to encode
Options	Bit 0 writes Interpolate, bit 1 enables symbol dictionaries where available, bit 2 prefers the external encoder backend, and bit 3 enables isolated black-dot cleanup before encoding
BlackDotSize	Maximum isolated black-pixel cluster size removed when cleanup is enabled
LossyLevel	Cleanup aggressiveness hint from 0 to 9 for scanned monochrome input

Returns the new ImageID, or 0 when the bytes cannot be read or encoded

Use this overload when bitmap input is already available in memory and no file or stream object is needed
