+

+ + + + + + + + + + + + + + + + + + + + + + + +

	Change	Effect
1	Field description has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.
2	Field image_buffer_size has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.
3	The relative position of field height has been changed from 13 to 14.	Applications will access incorrect memory when attempting to access this field.
4	The relative position of field width has been changed from 12 to 13.	Applications will access incorrect memory when attempting to access this field.

Problems with Data Types, Low Severity 3

+worksheet.h
+ +[+] struct lxw_image_options 3 +
+

+ + + + + + + + + + + + + + + + + + +

	Change	Effect
1	Size of this type has been changed from 144 bytes to 160 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
2	Field is_image_buffer has been added to this type.	This field will not be initialized by old clients. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
3	Field short_name has been renamed to image_buffer.	Renaming of a field in data type may indicate a change in the semantic meaning of the field.
