parstack, - the current stack of tag attributes |
|
from the xml parser |

Converts a measurement in to mm from any of |

|
|
Wrap image 'stuff' inside of the LaTeX required to implement |
|
alignment: |
|
align_tex_image(align, latex_rendering, image) |

Where: |
|
align - The HTML alignment specification. |
|
latex_rendering - rendering hint for latex. |
|
image - The LaTeX needed to insert the image itsef. |
|
width,height - dimensions of the image. |
|
Returns: |
|
The 1/2 wrapped image and the stuff required to close the |
