- As an aide, in addition to standard metadata tags, Geeqie provides a number of\r
- <link linkend="formatted_exif">pre-formatted tags</link>\r
- .\r
- </para>\r
- <para>Examples of usage are:</para>\r
- <para>\r
- <programlisting xml:space="preserve">\r
- %keywords%\r
- %Exif.Photo.DateTimeOriginal%\r
- %lua/jpeg_comment.lua/:12%\r
- %lua//return(os.date())%\r
- </programlisting>\r
- </para>\r
- <para>\r
- Refer to\r
- <link linkend="GuideReferenceLua">Lua Extensions</link>\r
- for further information.\r
- </para>\r
- <para>\r
- The length of displayed data can be limited by using the\r
- <emphasis role="italic">:max_length</emphasis>\r
- parameter. The following example will truncate the displayed data to 20 characters and will add 3 dots at the end to denote the truncation.\r
- <programlisting>%formatted.Camera:20%</programlisting>\r
- </para>\r
- <para>\r
- If two or more variables are connected with the\r
- <code>|</code>\r
- character, the variables are displayed with a separator. For example::\r
- <programlisting>%formatted.ShutterSpeed%|%formatted.ISOSpeedRating%|%formatted.FocalLength%</programlisting>\r
- could show:\r
- <programlisting>"1/20s - 400 - 80 mm"</programlisting>\r
- Or, if there is no ISO information in the Exif data:\r
- <programlisting>"1/200 - 80 mm"</programlisting>\r
- </para>\r
- <para>If there is no data for a requested tag, the line is not displayed.</para>\r
- <para>\r
- The\r
- <emphasis role="italic">:extra</emphasis>\r
- parameter may be used to format the output by prepending and appending a text string to the displayed item.\r
- </para>\r
- <para>\r
- The special character\r
- <code>*</code>\r
- is used to mark the position of the Tag data item. If no\r
- <code>*</code>\r
- is present, the extra string is just appended to the standard data displayed. Any "\n" is replaced by a newline on display.\r
- <link linkend="GuideReferenceStandards">Pango mark up</link>\r
- is accepted in both left and right parts. If the data item is empty, nothing will be displayed.\r
