mPDF 5.7.1

01/09/2013

  1. FILES: mpdf.php

Bug fix; Dollar sign enclosed by <pre> tag causing error. Test e.g.: <pre>Test $1.00 Test</pre> <pre>Test $2.00 Test</pre> <pre>Test $3.00 Test</pre> <pre>Test $4.00 Test</pre>

  1. FILES: includes/functions.php AND mpdf.php

Changes to preg_replace with /e modifier to use preg_replace_callback (/e depracated from PHP 5.5)

  1. FILES: classes/barcode.php

Small change to function barcode_c128() which allows ASCII 0 - 31 to be used in C128A e.g. chr(13) in: <barcode code="5432&#013;1068" type="C128A" />

  1. FILES: mpdf.php

Using $use_kwt ("keep-[heading]-with-table") if <h4></h4> before table is on 2 lines and pagebreak occurs after first line the first line is displayed at the bottom of the 2nd page. Edited so that $use_kwt only works if the HEADING is only one line. Else ignores (but prints correctly)

  1. FILES: mpdf.php

Clearing old temporary files from _MPDF_TEMP_PATH will now ignore "hidden" files e.g. starting with a "." .htaccess, .gitignore etc. and also leave dummy.txt alone

config.php

Removed:

  • $this->hyphenateTables
  • $this->hyphenate
  • $this->orphansAllowed Edited:
  • "hyphens: manual" - Added to $this->defaultCSS
  • $this->allowedCSStags now includes '|TEXTCIRCLE|DOTTAB' New:

  • $this->h2bookmarks = array('H1'=>0, 'H2'=>1, 'H3'=>2);
  • $this->CJKforceend = false; // Forces overflowng punctuation to hang outside right margin (used with CJK script)

Backwards compatability

Changes in mPDF 5.7 may cause some changes to the way your documents appear. There are two main differences:

  1. Hyphenation. To retain appearance compatible with earlier versions, set the CSS property "hyphens: auto" whenever you previously used $mpdf->hyphenate=true;
  2. Table of Contents - appearance can now be controlled with CSS styles. By default, in mPDF 5.7, no styling is applied so you will get:
    • No indent (previous default of 5mm) - ($tocindent is ignored)
    • Any font, font-size set ($tocfont or $tocfontsize) will not work
    • HyperLinks will appear with your default appearance - usually blue and underlined
    • line spacing will be narrower (can use line-height or margin-top in CSS)

New features / Improvements

  • Layout of Table of Content ToC now controlled using CSS styles
  • Text alignment on decimal mark inside tables
  • Automatically generated bookmarks and/or ToC entries from H1 - H6 tags
  • Support for unit of "rem" as size e.g. font-size: 1rem;

  • Use of <dottab> enhanced by custom CSS "outdent" property
  • Image HTML attributes <img> added: max-height, max-width, min-height and min-width
  • Spotcolor can now be defined as it is used e.g. color: spot(PANTONE 534 EC, 100%, 85, 65, 47, 9);

Bug fixes

  • SVG images - path including e.g. 1.234E-15 incorrectly parsed (not recognising capital E)
  • Tables - if a table starts when the Y position on page is below bottom margin caused endless loop
  • Float-ing DIVs - starting a float at bottom of page and it causes page break before anything output, second new page is forced
  • Tables - Warning notice now given in Table footer or header if <tfoot> placed after <tbody> and table spans page
  • Columns - block with border-width wider than the length of the border line, line overflows
  • Columns - block with no padding containing a block with borders but no backgound colour, borders not printed
  • Table in Columns - when background color set by surrounding block element - colour missing for height of half bottom border.
  • TOCpagebreakByArray() when called by function was not adding the pagebreak
  • Border around block element - dashed not showing correctly (not resetting linewidth between different edges)
  • Double border in table - when background colour set in surrounding block element - shows as black line between the 2 bits of double
  • Borders around DIVs - "double" border problem if not all 4 sides equally - fixed
  • Borders around DIVs - solid (and double) borders overlap as in tables - now fixed so mitred joins as in browser [Inadvertently improves borders in Columns because of change in LineCap]
  • Page numbering - $mpdf->pagenumSuffix etc not suppressed in HTML headers/footers if number suppressed
  • Page numbering - Page number total {nbpg} incorrect - e.g. showing decreasing numbers through document, when ToC present
  • RTL numerals - incorrectly reversing a number followed by a comma
  • Transform to uppercase/lowercase not working for chars > ASCII 128 when using core fonts
  • TOCpagebreak - Not setting TOC-FOOTER

  • Image problem if spaces or commas in path using http:// URL (included in release mPDF 5.6.1)
  • Image URL parsing rewritten to handle both urlencoded URLs and not urlencoded (included in release mPDF 5.6.1)

NB mPDF 5.5 added support for <fieldset> and <legend> (omitted from ChangeLog)

mPDF 5.5

  • classes/svg.php

classes/ttfontsuni_analysis.php

config.php changes

To avoid just the border/background-color of the (empty) end of a block being moved on to next page (</div></div>)

$this->margBuffer = 0; // Allow an (empty) end of block to extend beyond the bottom margin by this amount (mm)

config_fonts.php changes

Added to (arabic) fonts to allow "use non-mapped Arabic Glyphs" e.g. for Pashto 'unAGlyphs' => true,

Arabic text

Arabic text (RTL) rewritten with improved support for Pashto/Sindhi/Urdu/Kurdish Presentation forms added: U+0649, U+0681, U+0682, U+0685, U+069A-U+069E, U+06A0, U+06A2, U+06A3, U+06A5, U+06AB-U+06AE, U+06B0-U+06B4, U+06B5-U+06B9, U+06BB, U+06BC, U+06BE, U+06BF, U+06C0, U+06CD, U+06CE, U+06D1, U+06D3, U+0678 Joining improved: U+0672, U+0675, U+0676, U+0677, U+0679-U+067D, U+067F, U+0680, U+0683, U+0684, U+0687, U+0687, U+0688-U+0692, U+0694, U+0695, U+0697, U+0699, U+068F, U+06A1, U+06A4, U+06A6, U+06A7, U+06A8, U+06AA, U+06BA, U+06C2-U+06CB, U+06CF

Note - Some characters in Pashto/Sindhi/Urdu/Kurdish do not have Unicode values for the final/initial/medial forms of the characters. However, some fonts include these characters "un-mapped" to Unicode (including XB Zar and XB Riyaz, which are bundled with mPDF). 'unAGlyphs' => true, added to the config_fonts.php file for appropriate fonts will

This requires the font file to include a Format 2.0 POST table which references the glyphs as e.g. uni067C.med or uni067C.medi: e.g. XB Riyaz, XB Zar, Arabic Typesetting (MS), Arial (MS)

NB If you want to know if a font file is suitable, you can open a .ttf file in a text editor and search for "uni067C.med" - if it exists, it may work! Using "unAGlyphs" forces subsetting of fonts, and will not work with SIP/SMP fonts (using characters beyond the Unicode BMP Plane).

mPDF maps these characters to part of the Private Use Area allocated by Unicode U+F500-F7FF. This could interfere with correct use if the font already utilises these codes (unlikely).

mPDF now deletes U+200C,U+200D,U+200E,U+200F zero-widthjoiner/non-joiner, LTR and RTL marks so they will not appear even though some fonts contain glyphs for these characters.

Other New features / Improvements

Avoid just the border/background-color of the (empty) end of a block being moved on to next page (</div></div>) using configurable variable: $this->margBuffer;

The TTFontsUni class contained a long function (extractcoreinfo) which is not used routinely in mPDF

This has been moved to a new file: classes/ttfontsuni_analysis.php.

The 3 utility scripts have been updated to use the new extended class:

  • utils/font_collections.php
  • utils/font_coverage.php
  • utils/font_dump.php

Bug fixes

  • Border & background when closing 2 blocks (e.g. </div></div>) incorrectly being moved to next page because incorrectly calculating how much space required
  • Fixed/Absolute-positioned elements not inheriting letter-spacing style
  • Rotated cell - error if text-rotate set on a table cell, but no text content in cell
  • SVG images, text-anchor not working
  • Nested table - not resetting cell style (font, color etc) after nested table, if text follows immediately
  • Nested table - font-size 70% set in extenal style sheet; if repeated nested tables, sets 70% of 70% etc etc
  • SVG setting font-size as percent on successive <text> elements gives progressively smaller text
  • mPDF will check if magic_quotes_runtime set ON even >= PHP 5.3 (will now cause an error message)
  • not resetting after 2 nested tags of same type e.g. <b><b>bold</b></b> still bold
  • When using charset_in other than utf-8, HTML Footers using tags e.g. <htmlpageheader> do not decode correctly
  • ToC if nested > 3 levels, line spacing reduces and starts to overlap
