Converting PDF to image

Mar 9, 2010 3:09 AM

Hi,

 

1.We need to convert the each page of the PDF to JPG image in JAVA .

 

   Do Acrobat SDK or any other Acrobat product provide API or SDK to do so?.

 

2. Is it possible to get the Orginal dimension  and the DPI  information (if the document is created in photoshop with 2000 X 1428 pixel as dimensions and DPI as 300) for each page.If so that is the API we can use for it.

 

Regards,

Uvaraj S.

    Adobe provides this capability, server-side (where Java normally runs), via our LiveCycle product family - specifically PDF Generator.

     

    A PDF page has dimensions (called the MediaBox) but not a DPI.  DPI would be tied to an image(s) on the page.

    Hi,

     

    Thanks for the infomration.

     

    1.Is it possible to implement the same without using any servers.As a sandalone jar(provided by Adobe) with only a simple java file.

    Like how we use Adobe to create PDF.

    2.Is it possible to use the same Adobe SDK which is used to create PDF to create images from PDF?.

     

    Regards,

    Uvaraj S.

    Hi,

    I am attaching ther PDF which we use for the conversion.

     

    Width  :1667 px

    Height :1192 px

     

    Document Width :6.668 inches

                    Height:4.768 inches

     

    DPI is 250 pixels/inch.

     

    When i open the same docuent in notepad I am able see the header information as /MediaBox [ 0 0 480 343 ]

     

    which is nothing but (1667/250)*72 and (1192 /250)*72.

     

    we want the values as

    Width  :1667 px and

    Height :1192 px

    is it possible to get?.

    Adobe does not provide such a Java library.

     

    Yes, it is possible to use the Acrobat SDK on a desktop computer via C/C++ APIs to create images from PDF.

    We provide C/C++ APIs in the Acrobat SDK that would let you iterate over the contents of a PDF, locate each image, and then determine such information.
