Bleeding pictures as floats?

Bleeding pictures as floats?

[Henning Hraban Ramm]

Hi, I hope BachoTeX was a success!

Is it possible to use the float placing mechanisms for pictures that go beyond the type area or even beyond the page?

In the book I’m typesetting, most pictures need to fill the whole width of the page (i.e. plus 3mm bleed), but not all cover a full page.

I don’t know how to tell \externalfigure or \placefloat a negative offset.
Or can I use layers with floats? Of course the text should flow around the pictures.

BTW, what does the „object“ key of \setupexternalfigures do?

Greetlings, Hraban

Does the details manual  [1] answer your questions?

Thank you, that helped, but not enough.

I have now:

\def\bleed{3mm}
\def\maxWidth{\dimexpr(\paperwidth+\bleed)}

\definefloat[bleedfigure][figure]
\setupfloat[bleedfigure]
[
outermargindistance=-\bleed, % does that exist?
leftmargindistance=-\bleed,
rightmargindistance=-\bleed,
default={cutspace,none},
maxwidth=\maxWidth
]

\def\topfig#1#2{\placebleedfigure[top]{#1}{\offset[topoffset=\dimexpr(-\topspace-\bleed)]{\externalfigure[#2][width=\maxWidth]}}}

With that my pictures start at 0,-3mm, but they should start at -3mm,-3mm on a left page. Their maximum width is only \paperwidth, without bleed.
Where’s my mistake?

Use \definemeasure and \measure to set your own dimensions.

It is also bad style to redefine the \bleed command.

Can you make a working minimal example.

Ok, forgot about that.

So, one of my mistakes was, I had set \setupexternalfigures[maxwidth=\paperwidth], that overrides all other float definitions.

With this (perhaps not minimal) example I get nearly what I want, but the image starts with the paper and is centered (x/y -1,5mm/0mm) where I want it to start on -3mm/-3mm on a left page, 0mm/-3mm on a right page. I thought my definitions should do that...

You don’t have to use \dimexpr because the measure macros already us it.

There is only a “outermargin”  key but not “outermargindistance”.

The space before the image isn’t fixed when you use \setuplayout[grid=yes] because ConTeXt has to change it to ensure the text after the floats stays on the page.

%\setuplayout[grid=yes] % uncomment to see how the space before the images changes

\showframe

\placefigure[top]{Dummy}{\externalfigure[dummy]}

Ah, never had thought of that, thanks for the pointer!

But I want my pictures starting at that fixed position AND my (body) text keeping the grid.

Is that possible?
