Image version 0.45.0

Breaking changes

The implementations of Image.text/2 and Image.simple_text/2 have been simplified to use only the built-in Pango renderer. A bug in font sizing using the Pango renderer has also been fixed. As a result, there may be some small visual differences between text images generated by Image 0.45.0 compared to previous releases.

• Image.text/2 now uses only the built-in Pango renderer for all use cases. SVG is not nhow used for any rendering in Image.text/2 or Image.simple_text/2. This gives a more consistent output and less ambiguity. However as a result, a small number of options are no longer available since they cannot be honoured by Pango:

  • :text_stroke_color

  • :text_stroke_width

• The :autofit option to Image.text/2 is also removed. The autofit capability is now controlled by whether the :width and/or :height options are provided.

• Some other options are now treated differently in Image.text/2:

  • :width and :height are now truly optional. If ommitted, the renderer will calculate the required image size based upon the other options. It is acceptable to specify :width and omit :height in which case the maximum width is fixed and the height is variable.

Bug Fixes

• Fix warnings on upcoming Elixir 1.17.

• A bug resulting in incorrect font sizing with using the Pango renderer has been fixed. Font sizing is now very similar to the sizing of the previously used SVG renderer.
