Hi,
I'm getting stuck with GDPicture, because i can't mix JPG & CCITT4 within a multipage tiff.
Also the JPG pages are much bigger (in size) then a JPG to a single TIFF file
(this is due to the CMYK colorspace in single TIFF ? )
Any change on improvements here ?

Different Compression type for tiff MultiPage image
Posted: Thu Jun 27, 2013 5:07 pm
by kv981857
My target is to scan multiple image and need to append/save as tiff image which should have Compression (CCITT T.6), Resolution (300 * 300 dpi) and Dimension (2500 * 3300) but iam getting a tiff image with different Compression (LZW) from second page onwards.
Here is my simple code:
nImageID = axImaging1.GetNativeImage();
axImaging1.TwainSetErrorMessage(false);
axImaging1.TwainSelectFeeder(true);
axImaging1.TiffSaveAsNativeMultiPage((appPath + "Karthik_20130627192535.tif"), GdPicturePro5.TifCompression.CompressionCCITT4);
//'' abouve pice of code will create a tiff image with expected format
axImaging1.CloseImage(nImageID);
axImaging1.TiffCloseNativeMultiPage();
axImaging1.TwainCloseSource();
nImageID = axImaging1.GetNativeImage();
nTiffOriginal1 = axImaging1.TiffCreateMultiPageFromFile("Karthik_20130627192535.tif");
nTiffOriginal2 = axImaging1.TiffCreateMultiPageFromFile("Karthik_201306271925351.tif");
axImaging1.TiffAppendPageFromGdPictureImage(nTiffOriginal1, nTiffOriginal2);
axImaging1.TiffSaveMultiPageToFile(nTiffOriginal1, (appPath + "Karthik_20130627192535_3.tif"), GdPicturePro5.TifCompression.CompressionCCITT4);
I could able to save it correct format when iam tring to save singe page by useing below code;
axImaging1.TiffSaveAsNativeMultiPage(("Karthik_20130627192535.tif"), GdPicturePro5.TifCompression.CompressionCCITT4);
Note:
* It is working fine in Windows XP but iam facing issues in Windows 7 32/64 bit OS.
* I have noticed that second page has in Compression (LZW) from the Microsoft Document Imaging tool.
* axGdViewer1.SetLicenseNumber("XXX");
Please help me to resolve this issue ASAP.

Was this ever implemented?
I have just bought the ultimate edition for quite a substantial amount of money and all the tiff save methods only have one option for compression, and no way to set independent compressions for black&white and colour. The only option I see is "Auto" which saves both colour and black&white in lossless formats, which results in massive multipages.
This post states it would be implemented in version 10.... I'm on 14 and don't see a way?
Kind regards,
Matt

is there any progress on the second question in the original post?
I am currently evaluating GdPicture as a possible replacement for our current scanning and imaging library.
So far the GdPicture library (vb .net) is looking excellent, but we have hit an issue regarding saving pages to a TIFF file that have different compressions (e.g. CCITT4 for B&W and LZW for colour).
I can only find functions in the library that apply a single compression level to the whole TIFF file,
rather than to the individual pages within the file. As our current library allows this,
and is a feature that our Customers are currently using,
then I would really like to find a way to do this with GdPicture.
So, is there any way to currently do this, or is anything planned?
Many thanks

Hi there,
We've implemented custom compression at page-level since few years now.
Please find here and example:

I hope this feature will be available within 2 month.
It is very hard for us to implement this feature without rewriting all our multipage tiff plugin.
