MasterChangelog

This page contains notes about features and fixes that will be shipped in future releases. For notes on already released Prawn versions, see our regular CHANGELOG.

Keep in mind that no decisions on these changes are final until we actually cut a release, but do try out new features and fixes and tell us what you think about them!

To be released in 2.0.0 (merged in master)

All decimals in PDF output are now rounded to a fixed precision of 4 decimal places

This should improve compatibility across viewers that do not support arbitrarily long decimal numbers, without effecting practical use at all. (A PDF point is 1/72 inch, so 0.0001 PDF point is a very, very small number).

This patch was added in response to certain PDFs on certain versions of Adobe Reader raising errors when viewed.

Fix text width calculation to prevent unnecessary soft hyphen

(Elaborate here)

https://github.com/prawnpdf/prawn/pull/786

Fix broken valign for center and bottom

(Elaborate here)

Note that because this has been broken for so long, folks may have assumed the original behavior was intentional. Check your code to see if you’ve been working around this issue, because if so it may cause breakage.

Calling dash(0) now raises an error instead of generating a corrupt PDF

https://github.com/prawnpdf/prawn/commit/e65c24411c451918718a8e8cb35631c98ccc5517

Vastly improved handling of encodings for PDF built in (AFM) fonts

• Text for all Prawn methods is now UTF-8-in, UTF-8-out, so the user
  does not need to handle Windows-1252 strings.

• Internally, we’re now using Ruby’s M17n system to handle the encoding
  into Windows-1252, so text.encoding will come back as Windows-1252
  when `AFM#normalize_encoding` is called, rather than `ASCII-8Bit`

• When using AFM fonts + ASCII only text, no warning will be seen.

• When using AFM fonts + non-ASCII characters that are supported in
  Windows-1252, users will see a warning about the limited
  internationalization support, along with a recommendation to use a TTF
  font instead.

• The warning includes instructions on how to disable it (just set
  `Prawn::Font::AFM.hide_m17_warning = true`)

• When using AFM fonts + non-ASCII characters that are NOT supported in
• WIndows-1252, an exception will be raised rather than replacing w.
  `_`.

• None of the above will apply to anyone using TTF fonts with sane UTF-8
  support, everything should “just work” for those folks.

Margins are now restored properly when using go_to_page()

For a detailed discussion of the problem, see #272.

(Alexander Gitter / Gregory Brown, #794)

Using :indent_paragraphs now inserts indentation on the right side of the text when using RTL text rendering mode.
