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; - Origin and clipping for background images and gradients controlled by CSS i.e. background-origin, background-size, background-clip - Text-outline controlled by CSS (compatible with CSS3 spec.) - 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); - Lists - added support for "start" attribute in `<ol>` e.g. `<ol start="5">` - Hyphenation controlled using CSS, consistent with CSS3 spec. - Line breaking improved to avoid breaks within words where HTML tags are used e.g. H<sub>2<sub>0 - Line breaking in CJK scripts improved (and ability to force hanging punctuation) - Numerals in a CJK script are kept together - RTL improved support for phrases containing numerals and \ and / - Bidi override codes supported - Right-to-Left Embedding [RLE] U+202B, Left-to-Right Embedding [LRE] U+202A, U+202C POP DIRECTIONAL FORMATTING (PDF) - Support for `<base href="">` in HTML - uses it to SetBasePath for relative URLs. - HTML tag - added support for `<wbr>` or `<wbr />` - converted to a soft-hyphen - CSS now takes precedence over HTML attribute e.g. `<table bgcolor="black" style="background-color:yellow">` Added CSS support ----------------- - max-height, max-width, min-height and min-width for images `<img>` - "hyphens: none|manual|auto" as per CSS3 spec. - Decimal mark alignment e.g. text-align: "." center; - "rem" accepted as a valid (font)size in CSS e.g. font-size: 1.5rem - text-outline, text-outline-width and text-outline-color supported everywhere except in tables (blur not supported) - background-origin, background-size, background-clip are now supported everywhere except in tables - "visibility: hidden|visible|printonly|screenonly" for inline elements e.g. `<span>` - Colors: device-cmyk(c,m,y,k) as per CSS3 spec. For consistency, device-cmyka also supported (not CSS3 spec) - "z-index" can be used to utilise layers in the PDF document - Custom CSS property added: "outdent" - opposite of indent The HTML elements `<dottab>` and `<textcircle>` can now have CSS properties applied to them. 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 - TOCpagebreak - toc-even-header-name etc. not working - Parsing some relative URLs incorrectly - Textcircle - when moved to next page by "page-break-inside: avoid" - Bookmarks will now work if jump more than one level e.g. 0,2,1 Inserts a new blank entry at level 1 - Paths to img or stylesheets - incorrectly reading "//www.domain.com" i.e. when starting with two / - data:image as background url() - incorrectly adjusting path on server if MPDF_PATH not specified (included in release mPDF 5.6.1) - 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) - `<dottab>` fixed to allow color, font-size and font-family to be correctly used, avoid dots being moved to new page, and to work in RTL - Table {colsum} summed figures in table header - list-style-type (custom) colour not working - `<tocpagebreak>` toc-preHTML and toc-postHTML can now contain quotes mPDF 5.6 =========================== ### 20/01/2013 Files changed ------------- - mpdf.php - config.php - includes/functions.php - classes/meter.php - classes/directw.php config.php changes ------------------ - $this->allowedCSStags - added HTML5 tags + textcircle AND - $this->outerblocktags - added HTML5 tags - $this->defaultCSS - added default CSS properties New features / Improvements --------------------------- CSS support added for for min-height, min-width, max-height and max-width in `<img>` Images embedded in CSS - `<img src="data:image/gif;base64,....">` improved to make it more robust, and background: `url(data:image...` now added to work HTML5 tags supported - as generic block elements: `<article><aside><details><figure><figcaption><footer><header><hgroup><nav><section><summary>` - as in-line elements: `<mark><time><meter><progress>` - `<mark>` has a default CSS set in config.php to yellow highlight - `<meter>` and `<progress>` support attributes as for HTML5 - custom appearances for `<meter>` and `<progress>` can be made by editing `classes/meter.php` file - `<meter>` and `<progress>` suppress text inside the tags Textcircle/Circular - font: "auto" added: automatically sizes text to fill semicircle (if both set) or full circle (if only one set) NB for this AND ALL CSS on `<textcircle>`: does not inherit CSS styles - attribute: divider="[characters including HTML entities]" added - `<textcircle r="30mm" top-text="Text Circular Text Circular" bottom-text="Text Circular Text Circular" divider="&nbsp;&bull;&nbsp;" style="font-size: auto" />` &raquo; &rsquo; &sbquo; &bdquo; are now included in "orphan"-management at the end of lines Improved CJK line wrapping (if CJK character at end of line, breaks there rather than previous wordspace) NB mPDF 5.5 added support for `<fieldset>` and `<legend>` (omitted from ChangeLog) Bug fixes --------- - embedded fonts: Panose string incorrectly output as decimals - changed to hexadecimal Only a problem in limited circumstances. *****Need to delete all ttfontdata/ files in order for fix to have effect. - `<textCircle>` background white even when set to none/transparent - border="0" causing mPDF to add border to table CELLS as well as table - iteration counter in THEAD crashed in some circumstances - CSS color now supports spaces in the rgb() format e.g. border: 1px solid rgb(170, 170, 170); - CJK not working in table following changes made in v5.4 - images fixed to work with Google Chart API (now mPDF does not urldecode the query part of the src) - CSS `<style>` within HTML page crashed if CSS is too large (? > 32Kb) - SVG image nested int eht HTML failed to show if code too large (? > 32Kb) - cyrillic character p &#1088; at end of table cell caused cell height to be incorrectly calculated mPDF 5.5 =========================== ### 02/03/2012 Files changed ------------- - mpdf.php - classes/ttfontsuni.php - classes/svg.php - classes/tocontents.php - config.php - config_fonts.php - utils/font_collections.php - utils/font_coverage.php - utils/font_dump.php Files added ----------- 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 Older changes can be seen [on the documentation site](https://mpdf.github.io/about-mpdf/changelog.html).
