Hi all ! Smile

Marian thanks for your answers.

Dave, Now the GdPicture components stop to use the DA methods. You can update your component here for best results: http://www.gdpicture.com/ressources/betas/

Best regards,

Loïc Carrère

Dave, this is just a "current state" of QuickPDF answer.

At the moment there are 3x problems which may affect you:

 

1) DA function are not properly implemented. It seems that these were the original PDF manipulation functions and lack of several important improvements. This can be fixed in case you are willing to sponsor this correction and the result will be exposed in source code but only to you.

 

This case you can use QuickPDF with gpViewer activeX control and you will receive the same result as: STD Access Mode functions.

 

A solution is relative simple to implement.

 

2) The QuickPDF does not implement color space functions. As result some of the colors are not matched within an embedded index table.

 

As result some colored areas are wrong and produce very unpleasant results.

 

Solution complexity: moderate.

 

3) The QuickPDF does not implement ICC color profiles. This is not a very critical problem but may cause that colors are different rendered between QuickPDF and Acrobat programs (Foxit renders well).

 

As result some of the colors are slightly different with relative great difference when converting CMYK to RGB colors in Magenta/Blue range.

 

Solution complexity: development has moderate complexity but require intensive study of color profile specifications.

 

Info: PDF specs are relative well defined. Most of the problems are caused by a weak implementation or the size of PDF specification Tongue!!!

Marian, Ingo,

I said that Foxit renders the test.pdf correctly. Well 1.3 does, but 2.0 makes a complete mess of it. I don't know if this information helps you.

Are PDF standards as fluid/lax/ill-defined as I am starting to think they are?

Regards,

Dave

Marian,

I spoke to my contact very briefly this morning. They are out of their office for the rest of the week.  But they did say that the test.pdf was created with the same app as my newer ones.

The implication is that if you can solve the problems on that test.pdf, the other should show ok.

So I guess I have to ask if the problem is rooted in ColorSpaces? And, if it is, will there be a solution in QuickPDF in the very near future?

TIA

Dave

Marian,

I understand your need for visual evidence.

I cannot send the PDFs which cause me real problems because they are for a product that has not been launched yet. It is a Bank Holiday in the UK, but I will ask the studio tomorrow first thing for some more examples that I can share.

Your efforts are much appreciated.

Dave

Loïc, the result of your research is right. The set of DA* functions was never (and never will) used by me. The implementation is very strange and does not follow a clear programming logic.
 
In this case the problem is caused by the fact that jumping to Indirect PDF objects is not implemented inside DA* functions. The PDF contents are supposing tp make use of an Indirect ColorSpace object which will never work because of missing implementation.

Marian,

I spoke too soon. If I try Ingo's workaround with the new PDFs that I can't publish, they appear better than before, but large blocks of colour in the design are not shown at all :o(

If it is any consolation, ConvertIMage from SoftInterface cannot render these images correctly either. Only Foxit seems to display the same image as Acrobat. Looks like I have a studio who are at the "bleeding" edge of technology.

Dave

Marian,

No, the whole image was almost all monochrome. Some colour did survive. On the PDFs that I could not publish, spot colour swatches around the main design did appear ok, but the main design had objects missing or wrong colour info.

Using Ingo's workaround, the colour swatches in the bottom right of the image are still monochrome and some other colour swatches are missing. Is this still the "ColourSpace" problem?

HTH

Dave

PS Great support group! Shows what can be done when a group take ownership of a product.

Hi,
 
I've found the problem...
 
The RenderDocumentToFile() and DARenderPageToString() return differents data.
 
 
Try this sample in VB6:
 
 
Private Sub Form_Load()
 
Dim nDocumentID As Long, nPageID As Long
Dim hImageFile As Long
Dim sDocumentString As String
'Direct Access Mode
Dim oIsed As New iSED.QuickPDF
oIsed.UnlockKey ("354538350271B47ED3104F7CEC6FED8E")
nDocumentID = oIsed.DAOpenFile("c:\test.pdf", "")
nPageID = oIsed.DAFindPage(nDocumentID, 1)
sDocumentString = oIsed.DARenderPageToString(nDocumentID, nPageID, 1, 96)
hImageFile = FreeFile()
Open "c:\outputDA.jpg" For Binary As hImageFile
Put #hImageFile, , sDocumentString
Close #hImageFile
oIsed.DACloseFile (nDocumentID)
MsgBox "Done with Direct Access Mode!"

'STD Access Mode
oIsed.LoadFromFile ("c:\test.pdf")
Call oIsed.RenderDocumentToFile(96, 1, 1, 1, "c:\outputSTD.jpg")
oIsed.RemoveDocument (oIsed.DocumentID(1))
MsgBox "Done with STD Access Mode!"
 
End Sub
 
 
 
The DARenderPageToString() returns a grayscaled image Dead
 
Marian do you know how we can resolve this point ?
 
Best regards,
