There is an improvement: now the tags are identified as <Figure> and <Formula>! But still the figures label={this is a cow} is missing.
Sorry, Steffen, I thought I explained this in a previous message.
Alternative text is missing from \externalfigure, because this is the generated PDF object:
17 0 obj << /K [ << /Alt <FEFF0063006F0077> /MCID 1 /Pg 1 0 R /Type /MCR >> ] /P 15 0 R /Pg 1 0 R /S /image
endobj
But it should read:
17 0 obj << /K [ << /MCID 1 /Pg 1 0 R /Type /MCR >> ] /Alt <FEFF0063006F0077> /P 15 0 R /Pg 1 0 R /S /image
endobj
All I know is that it has to be fixed in lpdf-tag.lmt, but I don’t know how to fix it.
you can move the Alt and test local d = pdfdictionary { Type = pdf_mcr, Pg = pageref, MCID = last, } parent.dict.Alt = pdfunicode(label ~= "" and label or "image")
It is the same for alternative texts in formulas for PDF/UA-1.
you can play with -- Alt = alternate, NS = namespace, ActualText = actualtext or nil, Alt = actualtext or nil, NS = namespace, -- ActualText = actualtext or nil, and such to see if your viewer does soemthing useful Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
