+
+    Example of a bitmap that covers some of the area from cell A1 to cell B2.
+
+    Based on the width and height of the bitmap we need to calculate 8 vars:
+        col_start, row_start, col_end, row_end, x1, y1, x2, y2.
+    The width and height of the cells are also variable and have to be taken into
+    account.
+    The values of col_start and row_start are passed in from the calling
+    function. The values of col_end and row_end are calculated by subtracting
+    the width and height of the bitmap from the width and height of the
+    underlying cells.
+    The vertices are expressed as a percentage of the underlying cell width as
+    follows (rhs values are in pixels):
+
+           x1 = X / W *1024
+           y1 = Y / H *256
+           x2 = (X-1) / W *1024
+           y2 = (Y-1) / H *256
+
+           Where:  X is distance from the left side of the underlying cell
+                   Y is distance from the top of the underlying cell
+                   W is the width of the cell
+                   H is the height of the cell
+
+    Note: the SDK incorrectly states that the height should be expressed as a
+    percentage of 1024.
+
+    col_start  - Col containing upper left corner of object
+    row_start  - Row containing top left corner of object
+    x1  - Distance to left side of object
+    y1  - Distance to top of object

+'''
+The  XF  record is able to store explicit cell formatting attributes or the
+attributes  of  a cell style. Explicit formatting includes the reference to
+a  cell  style  XF  record. This allows to extend a defined cell style with
+some  explicit  attributes.  The  formatting  attributes  are  divided into
+6 groups:
+
+Group           Attributes
+-------------------------------------
+Number format   Number format index (index to FORMAT record)
+Font            Font index (index to FONT record)
+Alignment       Horizontal and vertical alignment, text wrap, indentation,
+                orientation/rotation, text direction
+Border          Border line styles and colours
+Background      Background area style and colours
+Protection      Cell locked, formula hidden
+
+For  each  group  a flag in the cell XF record specifies whether to use the
+attributes  contained  in  that  XF  record  or  in  the  referenced  style
+XF  record. In style XF records, these flags specify whether the attributes
+will  overwrite  explicit  cell  formatting  when  the  style is applied to
+a  cell. Changing a cell style (without applying this style to a cell) will
+change  all  cells which already use that style and do not contain explicit
+cell  attributes for the changed style attributes. If a cell XF record does
+not  contain  explicit  attributes  in a group (if the attribute group flag
+is not set), it repeats the attributes of its style XF record.

+From BIFF8 on, strings are always stored using UTF-16LE  text encoding. The
+character  array  is  a  sequence  of  16-bit  values4.  Additionally it is
+possible  to  use  a  compressed  format, which omits the high bytes of all
+characters, if they are all zero.
+
+The following tables describe the standard format of the entire string, but
+in many records the strings differ from this format. This will be mentioned
+separately. It is possible (but not required) to store Rich-Text formatting
+information  and  Asian  phonetic information inside a Unicode string. This
+results  in  four  different  ways  to  store a string. The character array
+is not zero-terminated.
+
+The  string  consists  of  the  character count (as usual an 8-bit value or
+a  16-bit value), option flags, the character array and optional formatting
+information.  If the string is empty, sometimes the option flags field will
+not occur. This is mentioned at the respective place.
+
+Offset  Size    Contents
+0       1 or 2  Length of the string (character count, ln)

+<p>
+This documentation is currently incomplete. There may be methods and
+classes not included and any item marked with a <em

+parameters, methods, attributes and functionality that are not
+documented. In these cases, you'll have to refer to the source if the
+documentation provided is insufficient.

+<h2>Module Contents <em style="color:red;">[NC]</em></h2>
+<dl>
+  <dt><b>easyxf</b> (function)</dt>
+  <dd>
+  <p>
+  This function is used to create and configure XFStyle objects
+  for use with (for example) the Worksheet.write method.
+  </p>
+  <dl>
+    <dt><i>strg_to_parse</i></dt>
+    <dd>
+      <p>
+      	A string to be parsed to obtain attribute values for Alignment, Borders, Font,
+      	Pattern and Protection objects. Refer to the examples
+      	in the file .../examples/xlwt_easyxf_simple_demo.py and to the xf_dict
+      	dictionary in Style.py. Various synonyms including color/colour, center/centre and gray/grey
+      	are allowed. Case is irrelevant (except maybe in font names). '-' may be used instead
+      	of '_'.<br />
+		Example: "font: bold on; align: wrap on, vert centre, horiz center"
+      </p>
+    </dd>
+    <dt><i>num_format_str</i></dt>
+    <dd>
+      <p>
+		To get the "number format string" of an existing cell whose format you want to reproduce,
+		select the cell and click on Format/Cells/Number/Custom. Otherwise, refer to Excel help.<br />
+		Examples: "#,##0.00", "dd/mm/yyyy"
+      </p>
