    IGR_LONG* width,
    IGR_LONG* height,
    Error_Control_Block* error);

Parameters¶

PageHandle: HPAGE

Handle to a page, opened by a call to IGR_Open_Page.

Width: Pointer to IGR_LONG

Returns the width of the page in pixels.

Height: Pointer to IGR_LONG

Returns the height of the page in pixels.

Error: Pointer to Error_Control_Block

Returns error details if the call fails.

Return value¶

Success: IGR_LONG

Returns IGR_OK.

Failure: IGR_LONG

Returns one of the possible IGR_E error codes.

Sample code¶

C/C++

Error_Control_Block ISYSError;
IGR_LONG Capabilities, DocType, DocHandle, PageCount, WordCount;
HPAGE PageHandle;

IGR_LONG RC = IGR_Open_Stream(pStream, IGR_FORMAT_IMAGE, &Capabilities, &DocType, &DocHandle, &ISYSError);
if (RC == IGR_OK)
{
    if (IGR_Get_Page_Count(DocHandle, &PageCount, &ISYSError) == IGR_OK)
    {
        for (IGR_LONG PageIndex = 0; PageIndex < PageCount; PageIndex++)
        {
            if (IGR_Open_Page(DocHandle, PageIndex, &PageHandle, &ISYSError) == IGR_OK)
            {
                IGR_LONG Width(0), Height(0);
                IGR_Get_Page_Dimensions(PageHandle, &Width, &Height, &ISYSError);
            }
        }
    }
    IGR_Close_File(DocHandle, &ISYSError);
}
