Sets the filled buffer array for any type VT_UI1 | VT_VECTOR properties.
#include "ltwrappr.h"
virtual L_INT LWia::SetPropertyBuffer(pItem, pszID, uID, pValue, uSize)
Valid pointer to a type IWiaItem (WIA 1.0) or IWiaItem2 (WIA 2.0) object, representing the item having the property.
Retrieve pItem by either calling the LWia::GetRootItem function to get a pointer to the device's root item, or by enumerating the child items of the device by calling LWia::EnumChildItems.
This string pointer should contain the equivalent property ID string for the WIA property ID (see example below):
| Property ID | Property ID Equivalent String |
|---|---|
| WIA_IPA_TYMED | WIA_IPA_TYMED_STR or "Media Type" |
| WIA_IPA_DEPTH | WIA_IPA_DEPTH_STR or "Bits Per Pixel" |
If pszID is NULL, the WIA toolkit uses the ID passed through the uID parameter; otherwise, the pszID parameter is used regardless of whether a valid property ID has been passed through the uID parameter.
The property ID of the property.
The uID parameter is required only if the pszID parameter is NULL; otherwise, you can pass 0 for this parameter.
Pointer to the buffer to be set for the property provided through the Property ID parameter.
Variable containing the allocated buffer size.
| Value | Meaning |
|---|---|
| SUCCESS | The function was successful. |
| < 1 | An error occurred. Refer to Return Codes. |
This feature is available in LEADTOOLS version 16 or higher.
Any WIA property of type VT_UI1 | VT_VECTOR that is not Read only can be set by calling [LWia:SetPropertyBuffer.
Since there is no Read/Write buffer property of type VT_UI1 | VT_VECTOR until now, then we can't provide
a sample for the SetPropertyBuffer function.
