經常在羣裏有人問，創建圖像的時候爲什麼老是提示下面的信息。
CPLError: Driver GTiff does not support DCAP_CREATE creation option
Warning 6: Driver GTiff does not support DCAP_CREATE creation option
CPLError: Driver GTiff does not support DCAP_CREATECOPY creation option
Warning 6: Driver GTiff does not support DCAP_CREATECOPY creation option
CPLError: Driver GTiff does not support DCAP_VIRTUALIO creation option
Warning 6: Driver GTiff does not support DCAP_VIRTUALIO creation option
CPLError: Driver GTiff does not support DMD_CREATIONDATATYPES creation option
Warning 6: Driver GTiff does not support DMD_CREATIONDATATYPES creation option
CPLError: Driver GTiff does not support DMD_CREATIONOPTIONLIST creation option
Warning 6: Driver GTiff does not support DMD_CREATIONOPTIONLIST creation option
CPLError: Driver GTiff does not support DMD_EXTENSION creation option
Warning 6: Driver GTiff does not support DMD_EXTENSION creation option
CPLError: Driver GTiff does not support DMD_HELPTOPIC creation option
Warning 6: Driver GTiff does not support DMD_HELPTOPIC creation option
CPLError: Driver GTiff does not support DMD_LONGNAME creation option
Warning 6: Driver GTiff does not support DMD_LONGNAME creation option
CPLError: Driver GTiff does not support DMD_MIMETYPE creation option
Warning 6: Driver GTiff does not support DMD_MIMETYPE creation option
CPLError: Driver GTiff does not support DMD_SUBDATASETS creation option
Warning 6: Driver GTiff does not support DMD_SUBDATASETS creation option測試的代碼如下：
GDALAllRegister();
GDALDriver *poDriver = GetGDALDriverManager()->GetDriverByName("GTiff");
char **papszCreateOptions = poDriver->GetMetadata();
GDALDataset *poDS = poDriver->Create("D:\\test.tif", 512, 512, 3, GDT_Byte, papszCreateOptions);
// do something
GDALClose((GDALDatasetH)poDS);上面的代碼中有個錯誤就是papszCreateOptions這個參數的值設置錯誤，如果沒有創建選項，就指定爲NULL就可以了，爲啥要獲取Dirver的元數據呢？？？
注意上面的代碼，Create函數或者CreateCopy函數中有個參數叫CreateOptions，這個參數的意思就是爲了指定創建圖像的一些特殊選項，比如Tiff圖像的壓縮方式，Jpeg圖像的壓縮率，ENVI的圖像存儲方式等等，每種驅動所對應的創建選項也不會相同，具體的都可以在gdal的官網中的格式說明中找到非常詳細的介紹，每種驅動頁面中只要是支持創建的格式一般都會有一個Cerete Options的章節，裏面就是這種格式的創建選項以及使用設置的參數信息。
知道了這個參數的原因，就明白了爲什麼會出現上面的提示，主要原因就是你設置的創建選項是錯誤的，所以GDAL提示了出來。
這個問題羣裏面非常多的人問，我覺得應該是有人在網上將這種錯誤的寫法貼出來了，所以我搜了下，下面的網址中的用法都是這個原因導致的。

最後希望大家在網上搜索資料的時候學會判斷哪些是對的，那些是錯誤的，不要一股腦的全部拿來用。
