WIA通过馈线扫描
这是我的设备属性:
Document Handling Select = 1 (2 is for flatbed, and 1 is for the feeder.)
这是我的项目(页面)属性:
Horizontal Resolution = 150
Vertical Resolution = 150
Horizontal Extent = 500 (I want to get it first to work, then I'll play with the extents.),
Vertical Extent = 500
Bits Per Pixel = 8
Current Intent = 4
如果我将"文档处理选择"设置为"2",我可以顺利运行一切.当我将它设置为"1"并运行它时,就在我说item.Transfer()(或item.Transfer(bmp/jpeg/pngGuid))之前我得到异常"值不在预期范围内".
这太烦人了,有什么价值？我用谷歌搜索了网络,我只能找到一些信息,但它没有多大帮助.
