How to do what i am trying to do?

In the past with the modified 0.23 I had a template using z-index and it worked.

But now I have upgraded to 1.0 its not working. (the compliance page says “No”)

So how can you specify the order of sections overlapping/overlaying rather than pushing each other out of the way.

I have

region-before (the header)

region-after (the footer)

region-start (the graphics)

region end (the faded background)

region-body (the text)

before we had the start and end in the body area not touching the header or footer but the end behind the start and the body over them all

so the Z-index is as follows

body = 1

start = 2

end = 3

so how can I do this?

Kindest regards

Re: How to do what i am trying to do?

Hi Theresa,

IIRC, under FOP 0.2x, body was drawn before other regions, as it was
under other.
With current FOP, the body is drown after other regions, as it is over
other.

You can try to change the region order in simple-page-master
declaration, I don't know if this can help or not.

Note that in strict mode, you cannot change the order in
simple-page-master declaration (body-before-after-start-end). You have
to unset it before (see at strict-configuration [1])

Hi Glen,

Any update on FOP release date with Gujarati font support?

Thanks,

Thanks for checking. I just ran the same data with Arial Unicode MS (see attached). There appears to be some issues on matra positioning. I'll look into this.

Hi Glen,

Language / ligatures are perfect in the PDF document. This is very encouraging, especially because the words in the document are quite complex.

I know that many users of my application use Arial Unicode MS on Windows and so that would be a good font family to test.

I'm thrilled to see it take shape! I'll be happy to review other documents you generate and once the code is stable, would be happy to test it out.

Hi Dilip,

Attached is a test FO file and resulting PDF I just generated with Gujarati support enabled. Could you take a quick look to verify. I used an excerpt from [1] as a sample.

I currently have only the Shruti (regular and bold) fonts from Windows 7 to test against. Do you have other Gujarati OpenType (1.5 or later) fonts you would like me to verify?

Null Poinuter exception in batik when using linearGradient

Hi,

With skynav-fop-de1b874, I get a NullPointerException in batik. I don’t think the problem is due to skynav. I also get a null pointer exception in fop-1.0, but without a stack trace. I suspect the fop trunk has been updated to include a stack trace in this case.

In any case, the attached .fo file won’t render the SVG with FOP. It seems to be complaining about a gradient I’ve defined but I don’t know which one or why.

Could anyone on this list help me with an insight or a work-around?

If I get rid of ALL the gradients the PDF renders fine, but my PDF rendering is supposed to be duplicating the HTML rendering of the SVG, which employs the gradients successfully in for example FireFox.
