Missing support for text elements

[meyfa]

There is no support for the <text> element and its possible child elements, like <tspan> or <font>.

Hi,

Please do needful for text and tspan tag parsing.

Thanks,
Mukesh

Does anyone working on it?
Actually I need it for a project, so maybe I can help. I'll add the nodes "text" and "textPath".

UPDATE: It's quite urgent for me, I'll open a pull request with what I've already done for text, but feel free to give any guidelines and what I should do in order to help you.

UPDATE: How should I implement the methods rasterize? Have you any documentation?

This feature is immensely important, for sure. There are a few caveats though:

• <tspan> elements can be nested arbitrarily inside <text>. The problem with this is that the whole library is built upon the idea that every node contains either nothing, text, or child nodes, but not a mixture of both text and nodes.
• Rasterizing text with the gd extension is also next to impossible when keeping in mind that it needs to be able to have stroke, letter spacing, and so on. Moreover, many servers will not have fonts installed, so font loading needs to be handled.

I did not yet have the time to come up with solutions.

Contributions are always welcome, so if you have figured something out, feel free to open a PR or add information to this issue :)

The rasterize method should invoke a custom renderer class through the given SVGRasterizer instance's render method. The renderer class needs to implement a method for rendering the stroked version of the shape (in this case, the text) and a method for rendering the filled-in version of the shape (text). See SVGEllipseRenderer.php for the most simple example. But, keep the aforementioned problems in mind.

Support for <text> and <textPath> reading/writing was added in commit c628ff3 through PR #42 by @thomas-blackbird (thank you!). This issue will stay open because the following are still unsupported:

• <tspan>
• rasterizer support
• arbitrary nesting of text nodes

Text rendering is now partially supported through PR #54.
