toFontInfo :: (MonadIO m, IsFontInfo o) => o -> m FontInfo

Cast to FontInfo, for types for which this is known to be safe. For general casts, use castTo.

noFontInfo :: Maybe FontInfo

A convenience alias for Nothing :: Maybe FontInfo.

Methods

free

fontInfoFree :: (HasCallStack, MonadIO m, IsFontInfo a) => a -> m ()

new

fontInfoNew

Arguments

:: (HasCallStack, MonadIO m, IsDocument a)

=> a

document: a Document

-> m FontInfo

Returns: a new FontInfo instance

Creates a new FontInfo object

scan

fontInfoScan

Arguments

:: (HasCallStack, MonadIO m, IsFontInfo a)

=> a

fontInfo: a FontInfo

-> Int32

nPages: number of pages to scan

-> m (Bool, FontsIter)

Returns: True, if there are more fonts left to scan

Scans the document associated with fontInfo for fonts. At most nPages will be scanned starting from the current iterator. iter will point to the first font scanned.

Here is a simple example of code to scan fonts in a document

<informalexample><programlisting> font_info = poppler_font_info_new (document); while (poppler_font_info_scan (font_info, 20, &fonts_iter)) { if (!fonts_iter) continue; /<!-- -->* No fonts found in these 20 pages *<!-- -->/ do { /<!-- -->* Do something with font iter *<!-- -->/ g_print ("Font Name: s\n", poppler_fonts_iter_get_name (fonts_iter)); } while (poppler_fonts_iter_next (fonts_iter)); poppler_fonts_iter_free (fonts_iter); } </programlisting></informalexample>
