RE: FOP inserting white space into SVG images

[Coutcher, Joseph James]

Title: Re: FOP inserting white space into SVG images

I have provided the sample output I'm getting at the following URL:

 

http://www.eng.utoledo.edu/~jcoutche/fop.pdf

 

Maybe "white space" wasn't the best description of the problem.  Take a look at the image in the PDF.  Now, look at the image size in the FO document (content-width, content-height, and viewBox):

 

                 <fo:instream-foreign-object content-width="180.8mm" content-height="30.0mm" background-color="red">
                     <svg:svg viewBox="0 0 180 30">
                         <svg:rect x="0" y="0" width="180" height="30" fill="none" stroke="black" />
                     </svg:svg>
                 </fo:instream-foreign-object>

As you will notice, the size I defined for it is rectangular, and not the square shape as FOP is rendering it as.

 

I have tried using instream-foreign-object and external-graphic (with content-width="180.8mm" content-height="30.0mm" background-color="red"), and I get the same results.  Yet, if I have a PNG file of the same dimensions, and use the exact same external-graphic element with the exact same parameters, it renders how it should.

 

This is the expected output:  http://eng.utoledo.edu/~jcoutche/fop2.pdf

 

The graphic I'm using needs to stay as an SVG, as I would rather it be embedded directly in the XML document.

 

Thanks!

 

Sincerely,

Joseph Coutcher

What do you mean by adding white space to the image? Do you mean there
is some white space above and below the image (which can't be really
seen with your fo sample)? If that is your problem try and set the
property line-height="0" on the enclosing block. This will stop any
white space being created at the top and bottom (usually referred to as
the 'half-leading') of all lines within the block.

If this is not your problem, that is I misunderstood what your are
asking, please try again to explain your problem with respect to the
additional white space.
