How to get PDF meta data using MUPDF

How to get pdf meta-data using MuPdf in Android ? I'm using MuPdf V1.7.

I can get Author & PDF name but I cannot get creation date, creator and etc. I used below function to get information:

fz_lookup_metadata(ctx, glo->doc, FZ_META_INFO_TITLE, info, sizeof(info));
fz_lookup_metadata(ctx, glo->doc, FZ_META_INFO_AUTHOR, info, sizeof(info));

Can anybody help?

Solution 
  • hi all i can get creation date from pdf by the below code.

add this into document.h
#define FZ_META_INFO_CREATIONDATE "info:CreationDate"

    paste the below code into mupdf.c

    JNIEXPORT jstring
JNICALL JNI_FN(MuPDFCore_metaPublishDate)(JNIEnv * env, jobject thiz)
{
    char info[64];
     globals *glo = get_globals(env, thiz);
     fz_context *ctx = glo->ctx;
     pdf_document *idoc = pdf_specifics(ctx, glo->doc);

     fz_lookup_metadata(ctx, glo->doc, FZ_META_INFO_CREATIONDATE, info, sizeof(info));

     return (*env)->NewStringUTF(env, info);
}

    then we can able to get this by core.metaPublishDate().
