Thanks Klaus,

I got the decoding part to work

but i don't understand how to pass the content of a file to encode function

[ABBKlaus]

Code: Select all

If ReadFile(0,"C:\somefile.txt")
  ASCII85.MEM_DataStructure
  ASCII85\pData=AllocateMemory(Lof(0))
  ASCII85\lCurSize=Lof(0)
  ASCII85\lMaxSize=Lof(0)
  ReadData(0,ASCII85\pData,Lof(0))
  CloseFile(0)
  
  Characters_per_line=60
  If pdf_ASCII85_Encode(@ASCII85,Characters_per_line)
    Message$=Chr(13)+Chr(13)+"Buffer = "+Str(ASCII85\lCurSize)+" Bytes !"
    Encoded_ASCII85$=PeekS(ASCII85\pData,-1,#PB_Ascii)
    MessageRequester("ASCII85 Encode",Encoded_ASCII85$+Message$)
    
    BufferLen=4096
    Buffer=AllocateMemory(BufferLen)
    If pdf_ASCII85_Decode(ASCII85\pData,ASCII85\lCurSize,Buffer,@OutBufferLen)=0
      Message$=Chr(13)+Chr(13)+"Buffer = "+Str(OutBufferLen)+" Bytes !"
      Decoded_ASCII85$=PeekS(Buffer,-1,#PB_Ascii)
      MessageRequester("ASCII85 Decoded",Decoded_ASCII85$+Message$)
    EndIf
  EndIf
EndIf

Hi,
I have used the pdf library with a lot of success. Many thanks.

In one application I have a full page background picture over which I print text and also place a logo, which is in PNG format. This works very well except I cannot find how to make the borders to the logo transparent, so my logo appears in a rectangular white box. The docs for pdf_Image() say that I need to specify a transparent colour, but I don't know how to do this. Can it be done with MS Paint or Paint.net?

Any suggestions are most welcome.

i think the documenation is wrong on that part because it says :

but are not supported:
- interlacing
- alpha channel

Regarding the images I have some questions and ideas:
- Is it possible to add a paperless format or is something like this already implemented?
- We can add images by full filename or memory address, I think it would be good to just pass a PureBasic ImageNr as well. Is there a restriction or could this be done easily?
- How can I add an image so that it always fits best the paper size and without loss of resolution?

How to change a space between lines in PurePDF? I want to change a space between lines in document with PurePDF but i cannot find a way to do it. I used Chunk and Paragraph for output text but they haven't any properties to change space between lines. Please help.

Sorry for my bad English =)

With this PurePDF it could look like this :

Code: Select all

pdf_Create()
pdf_AddPage()
pdf_SetMargins(30,10,30)
pdf_SetFont("Arial","",12)

txt$ = "Test"
pdf_SetX(30)
pdf_Write(5,txt$)
pdf_Ln(4)
pdf_Write(5,txt$)
pdf_Ln(5)
pdf_Write(5,txt$)
pdf_Ln(6)
pdf_Write(5,txt$)
pdf_Ln(7)
pdf_Write(5,txt$)

pdf_Save("Test.pdf")

But i guess you are looking for the purepdf Flash/Actionscript library for creating PDF files

Super! Danke, das sollte meine Probleme beheben.

small update, PurePDF V2.20

I downloaded this version, but the Help file for it says it's V2.08 still.

Also, got a question: I used this code to add a very tall image (5000 pixels high) to a new PDF file, but the image only went on the first page, and not continued over any next pages. How could I do that?

Code: Select all

pdf_Create()
pdf_AddPage()
pdf_Image("1280x5000.png",0,0,200)
pdf_Save("test.pdf")

Is it possible to open a PDF with this lib and save the doc as plain text back to disk?

[Jacobus]

Hi, I just tested this lib and I find it very useful, but I am unable to create a PDF with an RTF file and its formatting. Is this possible? and if yes, how to do that? Thanks.

Hi ABBKlaus,

any change to have this Lib for Mac OS X also???

Edit: Please

I've tried outputing unicode text using PurePDF and although it writes the ascii characters correctly, the unicode characters out of the normal ascii range are not displayed.

Is this a bug or a known restriction?
