Read PDF size to adjust size of next page

Question

I am trying to read the size of a PDF file to adjust the size of the next page to the size of the figure.
I have had some success, but the figure is still not well adjusted. I could adjust this figure, but I want to automate the adjustment, as I have 150 figures to insert in the file.
I also need to add an extra height on the page, to place the caption of the figure.
Any suggestion?
%-----------------------------------------------------------------
    setbox0 = hbox{includegraphics{01.pdf}}
    width = thewd0, height = theht0

newpage
%================================================================================
eject pdfpagewidth=thewd0 pdfpageheight=theht0

begin{figure}
    caption{<name picture>}
    includegraphics{01.pdf}
end{figure}

Here is an attempt using igrgraph command from incgraph pacakge. igrgraph{} automatically typesets in a separate page with height and width the same of , so you don't need to manually change page size. documentclass{article} usepackage{incgraph} usepackage{caption} begin{document} text on first page igrpage{% setbox0=hbox{includegraphics{example-image}}% begin{minipage}{wd0} captionof{figure}{figure on second page} box0relax end{minipage}% } text on third page end{document} This generates a three-page pdf, of which the second page is

I write:
%---------------------------------------------------
    newsavebox{measurebox}
    newlength{measuredwidth}
    newlength{measuredheight}
    newcommandmeasureimage[2][1]{%
        savebox{measurebox}{includegraphics[page=#1]{#2}}%
        setlength{measuredwidth}{wdmeasurebox}%
        setlength{measuredheight}{htmeasurebox}%
        savebox{measurebox}{}%
    } %-----------------------------------------------------------------------
measureimage[1]{01.pdf} % measures the 1nd page of the file.
    
newpage
    
newgeometry{left=0mm,right=0mm,top=0cm,bottom=0cm}
eject pdfpagewidth=measuredwidth pdfpageheight=measuredheight

begin{figure}[h]
includegraphics{01.pdf}
caption{caption picture}
end{figure}
%-----------------------------------------------------------------------

TO DO:
I still have to find out a way to insert a space below the figure to place the caption.
Any suggestions?
