pptx to SVG or any image

hi guys.
Can you help me find method to conver pptx to svg usual format. Not in svg in html.

The reason it is done this way is/was:

textArea (SVG 1.2 Tiny) - doesn't work in Chrome 4.0.249.64 or FF 3.5.7
so its not a feasible solution as at January 2010
See http://www.w3.org/TR/SVGTiny12/examples/textArea01.svg
from http://www.w3.org/TR/SVGTiny12/text.html#TextInAnArea
Opera 9.5 apparently supports it though!

Inkscape uses flowPara, but browsers can't render this.

carto textFlow.js works nicely in FF, but not Chrome

Do you know whether text support has markedly improved in SVG renderers since then?

nope. i can't give you a good answer.
but it would be cool have a choice.
is it difficult to implement?

Pretty straightforward to implement, but you would have to do it .. I don't have time right now.

Are you aware that only basic text and lines are currently supported; that is, the "well known" shapes such as stars, smiley faces etc etc aren't currently converted to SVG. Just wanting to set your expectations...

Yep. I know it. Can you give me advice from where i have to begin?

See docx4j/src/pptx4j/java/org/pptx4j/convert/out/svginhtml/pptx2svginhtml.xslt

Copy that and change the root template:

Code: Select all: <xsl:template match="/"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:svg="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink"> <head>

so it is producing svg not html, and change

Code: Select all: <xsl:template match="p:txBody"> : <div style="position: absolute; width:{$cx}px; height:{$cy}px; left:{$x}px; top:{$y}px;"> <xsl:apply-templates select="a:p"/> </div> : </xsl:template>

so it inserts svg for text, instead of that html.

You can create the svg in the xsl:template itself, or in an extension function. The template for p:cxnSp is an example of creating svg in an extension function.

Interested to hear how it works out, a year or so on :-)
