Hello, I use this code to merge file1.pdf, file2.pdf, file3.pdf in file4.pdf % format=english \definepapersize[A3large][width=320mm,height=450mm,offset=0pt] \setuppapersize[A3,landscape][A3large,landscape] \setuplayout [backspace=0pt,marking=on, height=middle,width=middle,location=middle, topspace=0pt, header=0pt, footer=0pt] \starttext'; \insertpages[file1.pdf][width=0pt] \insertpages[file2.pdf][width=0pt] \insertpages[file3.pdf][width=0pt] \stoptext where file1 is 481 031 bytes file2 is 1 277 167 bytes and file3 is 43 574 bytes. I expected ~2 Mbytes for file4.pdf but file4 is 10 601 693 bytes, ie ~five times the size expected. Why ? Thanks in advance luigi PS. I have a context distribution that is 1 year old, but i can't actually upgrade it (well, if I must do it, I will do !)
