Description

Hello,

It would be useful if there was an option to only place labels if they fit inside of the polygon. Currently the closest option that I am aware of is to set the "Suppress labeling of features smaller than" option. This option works great if all the labels will have the same number of characters - such as a Parcel Identification Number. However, "suppress labeling of feature classes smaller than" does not work well if we are labels have various lengths such as County Name.

I think there are three parts to making sure labels fit inside a polygon.
  1. Calculate the width of the label, which can be done by taking the font width * the number of characters. Or more specifically adding the width of each character up in a label as some fonts have different width characters.
  2. Calculate the feature width. - This algorithim is already figured out with the "suppress labeling of features smaller than..." option.
  3. Only place a label if the label width is shorter than the feature width.

Thank you for your consideration
