it seems that page numbers in the idv file (dvi file which contains
images) don't equate to filenames generated by dvisvgm. It is strange,
as it seems that some pages in the idv file weren't processed, they
are maybe empty. It might be some problem with your configurations or
document.

Anyway, it was probably bad idea to depend on page numbers in the idv
file, as image names from idv file are numbered consequently and image
names used by tex4ht as well. So there is new version of the .mk4
file:

-------------
Make:add("dvisvgm","dvisvgm -v1 -n -c 1.15,1.15 -p 1- ${input}.idv")
Make:htlatex {packages = "\\RequirePackage[dvipdfmx]{graphicx}"}
local max_count = 5


local image_pattern

local function file_exists(fn)
  local f = io.open(fn,"r")
  if f ==  nil then return false else f:close() return true end
end

local function search_file(input, ext, count)
  local pattern = count > 0 and "%s-%0"..count.."i." or "%s."
  pattern = pattern .. ext
  local filename = string.format(pattern, input, 1)
  if file_exists(filename) then
    return pattern
  elseif count < 0 then return nil
  else
    return search_file(input, ext, count - 1)
  end
end

local img_count = 0
local function locate_file(par,ext)
  if  image_pattern then
    img_count = img_count + 1
    return string.format(image_pattern, par.input,  img_count)
  else
    image_pattern =  search_file(par.input, ext, max_count)
    if not image_pattern then
      print("Cannot locate output svg pattern")
      return nil
    end
    return locate_file(par, ext)
  end
end


Make:htlatex{}
Make:htlatex{}
Make:htlatex{}
Make:tex4ht{}
Make:t4ht{}

Make:dvisvgm{}
Make:image("svg$",function(arg)
  arg.input = arg.source:gsub(".idv$","")
  local fn,msg = locate_file(arg, "svg")
  if not fn then
    print("Image processing error: "..msg)
  else
    arg.filename = fn
    local cmd = "mv ${filename} ${output}" % arg
    print(cmd)
    os.execute(cmd)
  end
end
)

OK,
