2.4.66 CrtLayout12

The CrtLayout12 record specifies the layout information for attached label, when contained in the sequence of records that conforms to the ATTACHEDLABEL rule, or legend, when contained in the sequence of records that conforms to the LD rule.

frtHeader (12 bytes): An FrtHeader structure. The frtHeader.rt field MUST be 0x089D.

dwCheckSum (4 bytes): An unsigned integer that specifies the checksum of the values in the order as follows, if the checksum is incorrect, the layout information specified in this record MUST be ignored.

Checksum for type	Values
AttachedLabel	x1 field of the Pos record in the sequence of records that contains this CrtLayout12 record and conforms to the ATTACHEDLABEL rule. y1 field of the Pos record in the in the sequence of records that contains this CrtLayout12 record and conforms to the ATTACHEDLABEL rule. An unsigned integer that specifies whether the attached label is at its default position. MUST be 1 if the dlp field of the Text record in the in the sequence of records that contains this CrtLayout12 record and conforms to the ATTACHEDLABEL rule is equal to 0xA. Otherwise, MUST be zero.
Legend	x1 field of the Pos record in the in the sequence of records that contains this CrtLayout12 record and conforms to the LD rule. y1 field of the Pos record in the in the sequence of records that contains this CrtLayout12 record and conforms to the LD rule. Width of the legend in pixels. Height of the legend in pixels. The fAutoPosX field of Legend record. The fAutoPosY field of Legend record. The fAutoSize of the Frame record in the in the sequence of records that contains this CrtLayout12 record and conforms to the LD rule.

The checksum is calculated using the following algorithm:

FUNCTION SimpleCheckSum values

SET dwChecksum to 0x0000

FOR each value in values

SET dwChecksum TO (dwChecksum XOR value)

RETURN dwChecksum

The width and height of legend in pixels are calculated with the following steps:

1. Get chart area width in pixels as indicated by section 2.2.3.17 "Chart Area"

2. Get chart area height in pixels as indicated by section 2.2.3.17 "Chart Area"

3. Compute legend size in pixels

   legend width in pixels = dx field of Legend / 4000 * chart area width in pixels

   legend height in pixels = dy field of Legend / 4000 * chart area height in pixels

A - unused (1 bit): Undefined and MUST be ignored.

B - autolayouttype (4 bits): An unsigned integer that specifies the automatic layout type of the legend. MUST be ignored when this record is in the sequence of records that conforms to the ATTACHEDLABEL rule. MUST be a value from the following table:

Value	Meaning
0x0	Align to the bottom
0x1	Align to top right corner
0x2	Align to the top
0x3	Align to the right
0x4	Align to the left

reserved1 (11 bits): MUST be zero, and MUST be ignored.

wXMode (2 bytes): A CrtLayout12Mode structure that specifies the meaning of x.

wYMode (2 bytes): A CrtLayout12Mode structure that specifies the meaning of y.

wWidthMode (2 bytes): A CrtLayout12Mode structure that specifies the meaning of dx.

wHeightMode (2 bytes): A CrtLayout12Mode structure that specifies the meaning of dy.

x (8 bytes): An Xnum (section 2.5.342) value that specifies a horizontal offset. The meaning is determined by wXMode.

y (8 bytes): An Xnum value that specifies a vertical offset. The meaning is determined by wYMode.

dx (8 bytes): An Xnum value that specifies a width or an horizontal offset. The meaning is determined by wWidthMode.

dy (8 bytes): An Xnum value that specifies a height or an vertical offset. The meaning is determined by wHeightMode.

reserved2 (2 bytes): MUST be zero, and MUST be ignored.
