ISO_19794_2_2005 support about sourceafis-java HOT 9 CLOSED

I don't understand what are you saying.

from sourceafis-java.

I suppose I understood he imports an ISO then exports it then matchs both initial and final .dat and there is no match, which would imply erros wether on input conv or output conv ?

from sourceafis-java.

I figured that much, but it makes no sense. A snippet, expected and actual output would help. Some explanation of how the OP came to that would also help improve the docs.

Yes, you are right.

Dear robertvazan
Any recommend for ISO_19794_2_2005 format convert?

from sourceafis-java.

I still don't understand the issue here. SourceAFIS mainline can import ISO 19794-2:2005 within limits of its current public description:

https://templates.machinezoo.com/iso-19794-2-2005

SourceAFIS doesn't do ISO template export yet as that would require information from the expensive ISO specs. I can nevertheless provide it for a fee (full ANSI378 support was also added thanks to a sponsor).

So it is not clear to me what are you doing since one of the steps in your description (export to ISO 19794-2) is not currently possible.

As I compared both iso-19794-2-2005 and ANSI378 specs，I foud only a few field difference. so I changed the SourceAFIS source code then do some export to ISO 19794-2 testing.

	/**
         *  ForeignTemplate.java 
	 *  template export  
	 * @param out
	 * @throws IOException
	  @*/
	void write(DataOutputStream out) throws IOException {
		//TODO ? IllegalStateException  ISO_19794_2_2005
//		if (format == ForeignFormat.ISO_19794_2_2005)
//			throw new IllegalStateException();
		//head
		writeFormatMarker(out);
		//version code
		writeVersion(out); 
		writeTemplateLength(out); 
		//ISO_19794_2_2005  skip it
		if (format != ForeignFormat.ISO_19794_2_2005){
			writeProductId(out);
		}
		writeSensorInfo(out);
//		if (format == ForeignFormat.ANSI_378_2004){
//			dimensions.write(out);
//		}
         //X image size Y image size X resolution Y resolution # of finger views Reserved byte
		if (format == ForeignFormat.ANSI_378_2004 ||format == ForeignFormat.ISO_19794_2_2005 ){
			dimensions.write(out);
		}
		//off views 01
		writeFingerprintCount(out);
        //Reserved byte 00
		out.writeByte(0);  
		// Single Finger View Minutiae Record 
		for (int i = 0; i < fingerprints.size(); ++i){
			fingerprints.get(i).write(out, format, i);
		}  
	}

So it is clear now. You are testing your own quick ISO 19794-2 implementation. Simply adjusting field structure is not sufficient. There are semantic differences. I dimly remember the angle encoding is different. There might be new required fields, so even if you manage to successfully roundtrip the format, the templates might still be rejected by 3rd party software.

I am closing this issue since it is about your own code rather than about SourceAFIS.

Thanks robertvazan, you are right, the angle encoding is different.
do you have any recommend ?
