maybe it's related to this (copied from pdftex sources in older versions): ,-------- | @!pdf_first_space_corr: integer; {amount of first word spacing while drawing a string; | for some reason it is not taken into account of the length of the string, so we | have to save it in order to adjust spacing when string drawing is finished} `-------- I have verified this as follows: uncompressed microtype.pdf, used a text editor to find where the line 3.1 Micro-Typographic Options . . . . . . . . . . . . . . . . . . . . . . 6 is drawn. It looks as follows: ,-------- | /F95 9.9626 Tf 14.944 -13.993 Td [(3.1)-910(Micro-)37(T)93(ypographic)-278(Options)]TJ | 0 g 0 G | [-970(.)-500(.)-500(.)-500(.)-500(.)-500(.)-500(.)-500(.)-500(.)-500(.)-500(.)-500(.)- 500(.)-500(.)-500(.)-500(.)-500(.)-500(.)-500(.)-500(.)-500(.)-500(.)]TJ | 0 g 0 G | [-1740(6)]TJ `-------- According to the above note, the first space is not taken into account of the string length, so I tried to add it (ie -970) to the space after the current TJ operator (ie to -1740 in the following TJ, so now it became -2710). After this the digit 6 ended up aligned as expected (but now it looks bad in xpdf). Thanh On Thu, Feb 08, 2007 at 11:16:02PM +0100, Hartmut Henkel wrote:

while viewing the microtype manual (from texlive2007) using acr4.0 on linux, I found some oddities as shown here:

Same under Windows, Acrobat Reader 4.05. Additionally, the page numbers on the right-hand side in the TOC are completely mis-aligned.

It appears fine when created with (miktex's) pdftex 1.30.

this still uses \pdfliteral {} without "direct", so you find (lengthy) coordinate transforms like this around color change commands in the PDF:

1 0 0 1 498.65 487.517 cm 0 g 0 G 1 0 0 1 -338.982 -13.027 cm 0.02 0.04 0.48 rg 0.02 0.04 0.48 RG 1 0 0 1 -159.668 -474.49 cm

With pdftex-1.40 now hyperref seems to use the more compact \pdfliteral direct {} version.

...

With 1.40, it looks OK if I set hyperref's colorlinks option to false (ie., have the links surrounded by boxes instead of coloured).

then the color change commands between the []TJ sections go away. It appears that acro4.0 doesn't like legal PDF like this:
