Fitting page size and position

[sadowsky-o-phd]

Hi Brad,

It's good to know that you continue to maintain CalTag. I really like it.

I have a feature request in the generate_pattern script. I want to embed the CalTag pattern in a larger calibration rig. For this, I need the pattern to be aligned with the page boundary and include a proper page size.

I did this manually a few times, but it's be nice to have in automated.

What's needed is a << PageSize statement around the head of the file, such as:

<< /PageSize [1700.79 1700.79] >> setpagedevice

And also an additional shift of the pattern origin (around line 51 of the ps file) to be translation of -4 -4 instead of -2 -2.

Another user might still want the pattern end to be completely within the page, not on the boundary, so it's a judgment call whether to do this. But for me, again, it'd be nice.

Thanks.

Thanks for the feedback. I don't mind making these changes, but would prefer to keep them on a separate branch. Do you mind submitting a pull request?

Unfortunately I don't have a Matlab license any more, so I don't actively maintain this project any more. It's been a while since I looked at PostScript - where does that 1700.79 number come from? Would it change depend on Letter/A4 page sizing?

The page size is user-defined in units of points, with 72 points per inch. You can compute it by taking the bounding box of the pattern in inches (if in centimeters then scale appropriately) and multiply by 72. Specifically, 1700.79 = (60 cm / 2.54) * 72.

I guess that there is a default, but to embed the pattern in another figure a realistic box should be defined.

The change would be in generate_pattern.py and does not involve Matlab.

The page size directive, like the one above (including all the << and >> signs) can come right before the config block.
