|
| |
=item resize_image() |
| |
|
| |
Get correct sizing parameter for an image given |
| |
it's initial ht. and wid. This allows sizing of |
| |
images that are generated on-the-fly (e.g. gnuplot) |
| |
as well as serving as a utility for image_size. |
| |
|
| |
Parameter: |
| |
height_param |
| |
width_param - Initial picture dimensions. |
| |
scaling - A scale factor. |
| |
parstack, - the current stack of tag attributes |
| |
from the xml parser |
| |
safeeval, - pointer to the safespace |
| |
depth, - from what level in the stack to look for attributes |
| |
(assumes -1 if unspecified) |
| |
cis - look for attrubutes case insensitively |
| |
(assumes false) |
| |
|
| |
Returns: |
| |
height, width - new dimensions. |

|
| |
Converts a measurement in to mm from any of |

the other valid LaTeX units of measure. |
| |
If the units of measure are missing from the |
| |
parameter, it is assumed to be in and returned |
| |
with mm units of measure |
