Choose PDF version

[zamazan4ik]

Hello,

I think you know that PDF standard has a lot of versions: 1.3,1.4,1.5, etc. Also there are A-type (Archive).

Is it possible to add this functionality? Abbyy FineReader has this. It will be useful for people, who has some software which cannot read very modern PDF documents.

Should be fairly easy, you can specify the version when creating the document here https://github.com/manisandro/gImageReader/blob/master/qt/src/OutputEditorHOCR.cc#L1143

The PdfStreamedDocument constructor signature is

PdfStreamedDocument( PdfOutputDevice* pDevice, EPdfVersion eVersion = ePdfVersion_Default, PdfEncrypt* pEncrypt = NULL, EPdfWriteMode eWriteMode = ePdfWriteMode_Default );

and EPdfVersion is

enum EPdfVersion {
    ePdfVersion_1_0 = 0,       /**< PDF 1.0 */
    ePdfVersion_1_1,           /**< PDF 1.1 */
    ePdfVersion_1_2,           /**< PDF 1.2 */  
    ePdfVersion_1_3,           /**< PDF 1.3 */ 
    ePdfVersion_1_4,           /**< PDF 1.4 */
    ePdfVersion_1_5,           /**< PDF 1.5 */
    ePdfVersion_1_6,           /**< PDF 1.6 */ 
    ePdfVersion_1_7            /**< PDF 1.7 */ 
};

Can I start work on it?

[manisandro]

Sure!

[zamazan4ik]

Nice. I will create some pull requests. And you will be able to see progress on every task.

[manisandro]

Looking forward to it! I was actually hoping to be able to do some work myself again, but I keep getting sidetracked with other stuff...

[zamazan4ik]

Don't worry - i think we have enough work in gImageReader for me and for you :-)
