for GetFileDimensions, Read methods.
obj.saFileStart
Parameters
The property has no parameters.
Note
This property affects the GetFileDimensions, Read
methods only if you use safearrays as a image source. There are cases then safearray
contains not only image data, but also some other ones. For example, if you got this
safearray on website from data uploaded by user with HTML form having type=file
field then safearray will contain some envelope data in addition to gif image data.
For such case your software has to parse data, locate where image begins, and assign the
zero-based number of the first byte of gif image to this propery
The default value is zero (image data start from the first byte of safearray).
