Re: More on external graphics
Hi Luis, I tried your initial FO (with negative margin) against FOP 1.0 and FOP trunk: FOP 1.0 is buggy while FOP trunk works as expected. In addition, note that with fo:external-object or fo:instream-foreign-object, there are half-leading before and after, that depend on font-size and line-height. So, if your fo:block contains no text, you can set its font-height to 0. If line-height has a ration value (witch is inherited and defaults to 1.2), you do not need to explicitely set it to 0 Le 16/12/2011 00:50, Luis Bernardo a écrit : On 12/15/11 7:44 PM, Samuel Penn wrote: On Thursday 15 December 2011 00:26:43 Luis Bernardo wrote: Your page definitions (margins, paddings, and so on) may be part of the problem.

I almost have things how I want them, I just need to do some print tests to make sure it looks okay. However, it seems to be that if the left/right page margins don't match, then I get the problem with misplaced images. e.g., if I take 1mm off the left margin on right hand pages, I need to also take 1mm off the right margin on left hand pages in order for images to be placed correctly.

Re: More on external graphics
Hi Samuel, I don't understand what you mean by if I take 1mm off the left margin on right hand pages... Can you provide a short snippet to illustrate, please? I know there is a bug in inline-progression-dimension computation when using 'mm' or 'cm' as unit, that can cause trouble when using inverted left/right margins, witch is the case with your XSL-FO (see [1]).

Re: More on external graphics
Hi Samuel, You have already figured out how to avoid the problem, but FYI, what you are witnessing is the result of a bug in the code that handles pages of different widths (the infamous Changing IPD feature). That bug appears to have been fixed in Trunk but I don’t remember when. Unless you have a good reason for wanting pages of different widths I advise you to make sure that the widths of the region-body on all your pages match. That is, make sure that the following operation: page-width − margin-left and margin-right on the simple-page-master − margin-left and margin-right on the region-body gives the same result for all your pages.

Take the following definitions for left and right pages (these can be plugged into the test.fo that Luis posted): fo:simple-page-master master-name=leftPage page-height=297mm page- width=210mm margin-top=15mm margin-bottom=15mm margin-left=15mm margin-right=30mm fo:region-body margin-left=20mm margin-right=21mm/ fo:region-before extent=15mm region-name=region-before-left/ fo:region-after extent=10mm region-name=region-after-left/ fo:region-start extent=20mm/ fo:region-end extent=10mm/ /fo:simple-page-master fo:simple-page-master master-name=rightPage page-height=297mm page- width=210mm margin-top=15mm margin-bottom=15mm margin-left=30mm margin-right=15mm fo:region-body margin-left=21mm margin-right=20mm/ fo:region-before extent=16mm region-name=region-before-right/ fo:region-after extent=10mm region-name=region-after-right/ fo:region-start extent=20mm/ fo:region-end extent=10mm/ /fo:simple-page-master Both are balanced, in that the margin-right/margin-left for both the simple-page-master and region-body mirror each other for the left and right pages. In this case, images are placed correctly. Concentrating on the following lines: left: fo:region-body margin-left=20mm margin-right=21mm/ right: fo:region-body margin-left=21mm margin-right=20mm/ If I change the margin-right for the left page to be 22mm, then the images are incorrectly placed on 2nd and subsequent pages (the problem that I was seeing). If I also update the margin-left for the right page to be 22mm however, then images are correctly placed again. There seems to be a similar constraint for the simple-page-master margins, in that left page needs to mirror right page. Changing the margins on one page (but not the other) breaks the images again.
