我有一个应用程序可以编辑JPEG图像的元数据部分。我必须删除缩略图元数据,而不用干扰其他元数据。我已经尝试了下面的代码,但没有成功删除缩略图元数据。我可以提前帮助我解决这个问题。
array<String^>^ query = gcnew array<String^>(4);
query[0] = "/app1/ifd/tiff:";
query[1] = "/app1/ifd/tiff/subifd:";
query[2] = "/ifd/tiff:";
query[3] = "/ifd/tiff/subifd:";
for each (String^ SetQuery in query)
{
metaData->RemoveQuery(SetQuery + "{uint=256}");
metaData->RemoveQuery(SetQuery + "{uint=257}");
metaData->RemoveQuery(SetQuery + "{uint=258}");
metaData->RemoveQuery(SetQuery + "{uint=259}");
metaData->RemoveQuery(SetQuery + "{uint=273}");
metaData->RemoveQuery(SetQuery + "{uint=262}");
metaData->RemoveQuery(SetQuery + "{uint=277}");
metaData->RemoveQuery(SetQuery + "{uint=278}");
metaData->RemoveQuery(SetQuery + "{uint=279}");
metaData->RemoveQuery(SetQuery + "{uint=282}");
metaData->RemoveQuery(SetQuery + "{uint=283}");
metaData->RemoveQuery(SetQuery + "{uint=284}");
metaData->RemoveQuery(SetQuery + "{uint=296}");
metaData->RemoveQuery(SetQuery + "{uint=513}");
metaData->RemoveQuery(SetQuery + "{uint=514}");
metaData->RemoveQuery(SetQuery + "{uint=529}");
metaData->RemoveQuery(SetQuery + "{uint=530}");
metaData->RemoveQuery(SetQuery + "{uint=531}");
metaData->RemoveQuery(SetQuery + "{uint=532}");
}
