PDF generation from tiff, jpeg...

[dominique]

Hi GFLSDK Team and friends,
I 'm testing translation from Jpeg or Tiff images to PDF format.
My objective is to save PDF with JPEG 80 encapsulated images for example.
If input image format is JPEG or TIFF, SDK saves PDF using TIFF LZW compression with no respect of save options.
If I do the same (with identical save options) from PDF input, SDK works fine respecting save options!
Even if save option structure seems to be ok (I use : FormatIndex, Compression and Quality), I think I miss something in options but don't see witch parameters.
Someone to help?

Do you change the Compression?

[dominique]

Yes I try to Change the Compression method.
With a JPEG or TIFF input :
If I choose No Compression, I have a PDF File which is a little bit bigger than my tiff=> ok that's fine
Same thing with LZW Compression (with a smaller output file).
If I put JPEG Compression with Quality X, the file generated is like a TIFF LZW.
I've compared save options between JPEG source and PDF source with the deboger and every options seems to be the same.
I continue reading Documentation and Forum
Thx for your help !

Here is an exemple of who I do :

Code: Select all

GFL_BITMAP              *mBitmap;
GFL_FILE_INFORMATION    mImageInfo;      // Données image
GFL_FORMAT_INFORMATION  mFormatInfo;     // Données sur le format de l'image
GFL_ERROR               mErr;            // Code d'erreur
GFL_LOAD_PARAMS         mLoadOption;     // Options d'ouverture de l'image
GFL_SAVE_PARAMS         mSaveOption;     // Options  d'écriture de l'image
gflLibraryInit();
gflGetDefaultLoadParams( &mLoadOption );
mErr = gflLoadBitmap( "toto.tif", &mBitmap, &mLoadOption, &mImageInfo );
if (!mErr)
{
                gflGetDefaultSaveParams(&mSaveOption);
                mSaveOption.FormatIndex = 54;
                mSaveOption.Compression = GFL_JPEG;
                mSaveOption.Quality     = 80;
                mErr = gflSaveBitmap( "toto.pdf", mBitmap, &mSaveOption);
                int toto = 13;          // break point
}
gflLibraryExit();

May it can show you my mistake!
