See PlotPlugin and Plugin classes for additional details. Parameters ---------- maxdist : float Maximum pixel distance allowed when selecting end point of scan line. limits : tuple or {None, 'image', 'dtype'} (minimum, maximum) intensity limits for plotted profile. The following special values are defined: None : rescale based on min/max intensity along selected scan line. 'image' : fixed scale based on min/max intensity in image. 'dtype' : fixed scale based on min/max intensity of image dtype. s Line Profilei t deprecatedtimagecK s7tt|ƒj|||_||_|jƒGHdS(N(tsuperRt__init__tmaxdistt _limit_typethelp(tselfR tepsilontlimitstkwargs((sAlib/python2.7/site-packages/skimage/viewer/plugins/lineprofile.pyR !s  cC sétt|ƒj|ƒ|j}|jdkrRtj|ƒtj|ƒf|_nk|jdkrwt |j j |_nF|jdks›t |jƒdkrª|j|_ntd|jƒ‚|jdk râ|jj|jƒn|jdd!\}}|dd|dg}|dgd}t|jd|jd|jd |jƒ|_tj||gƒ|j_tj||jjdd…ddd …fŒ}||_|jd krÎ|dd…tjf}n|j|ƒ|jƒdS( NRtdtypeisUnrecognized `limits`: %siiR ton_movet on_changeiÿÿÿÿi( R Rtattachtoriginal_imageR tnptmintmaxRRRttypetNonetlent ValueErrortaxtset_ylimtshapeRt image_viewerR t line_changedt line_toolt transposet end_pointsRt profile_linet scan_datatndimtnewaxist reset_axest_autoscale_view(RR!RthtwtxtyR'((sAlib/python2.7/site-packages/skimage/viewer/plugins/lineprofile.pyR(s4 $$    (  cC sd}dj|ƒS(NsLine profile tools8+ and - keys or mouse scroll changes width of scan line.s3Select and drag ends of the scan line to adjust it.s (sLine profile tools8+ and - keys or mouse scroll changes width of scan line.s3Select and drag ends of the scan line to adjust it.(tjoin(Rthelpstr((sAlib/python2.7/site-packages/skimage/viewer/plugins/lineprofile.pyR MscC s<|jƒg|jD]}|jƒ^q}|jj|fS(s'Return intensity profile of the selected line.
