Method Details

addDir(self, dirn, recurse=0, callback=[])

this function should be called by UI to add files.

addFiles(self, files, status, callback)

this function is called recusively through reactor.callLater status is a list of values to be passed through calls: [number_of_added, number_of_rejected] files is the list of files that still has to be added

status parm format: [0-error sum 1-added id list]

addImg(self, newid, fname)

add image to database. This will basically involve a call to the C++ module

returns thumbnail path on success, None on error

generateImageID(self)

need to return something unique

getImgData(self, fname)

returns image data Currently called by subclassed getImgData and getThumbImgData

getThumbName(self, fname)

return the thumbnail full path for the image given by fname (fname is full path)

open(self)

init c++ module db

querySig(self, sig, numres=20, thres=999999)

query for similar images. Source is a db image

Parameters:: numres - maximum number of results

Returns:: list of similar images. List of pairs [result id,result score] Score is 0-100
(type=list)

sync(self, reopen=1, noisy=1)

reopen parm is currently ignored
