如何在vista里显示图片缩略图

南卓铜 ([email protected])

Vista的资源管理器里浏览图片时默认仅显示图标。如图1所示,

图1 以图标形式出现的缩略图,这是Vista显示图片的默认方式

尽管双击图标,转到照片库,可以浏览图片内容的缩略图。我个人更偏向于如以前XP下直接在资源管理器里显示照片内容的缩略图。这其实是可以通过改变选项做到的。Vista默认禁止显示图片内容缩略图,估计是出于性能上的考虑。

单击“组织”菜单,在下拉菜单里选择“文件夹和搜索选项”(图2),确认“以缩略图形式显示文件图标”打上勾,并且去掉“始终显示图标,从不显示缩略图”前的勾。确定后,图片以内容缩略图的形式出现(图3)。

A Lab for using the PIHMgis and PIHM model (I)

Set up work place

1. Download PIHMgis version 2.0 from the URL:

http://www.pihm.psu.edu/PIHMgis_v2.0.0/PIHMgis_v2.0.0.zip

Download Shale Hills PIHMgis data files from the URL:

http://cid-0ea641a5a7f665a1.skydrive.live.com/self.aspx/Public/shale.hills.pihmgis.data.zip

Download qgis.1.0 from the URL:

http://cid-0ea641a5a7f665a1.skydrive.live.com/self.aspx/Public/qgis.1.0.zip

Note: The current PIHMgis v2.0 is built with QGIS 0.8 preview version and cannot run with QGIS 1.0 because APIs of those two version are inconsistent. The stable QGIS 1.0 version provides us a much better user interface and richer functionality than version 0.8. We will use QGIS 1.0 editing functions to manipulate vector data. The development team of PIHMgis is working on the migration to QGIS 1.0, which might be available in near future.

2. Make a directory “PIHM-lab”, and then extract “PIHMgis_v2.0.0.zip” to this directory. Go to this PIHMgis_v2.0.0 folder, locate “PIHMgis_v2.0.0.exe”, make a shortcut and rename the shortcut to “PIHMgis_v2.0.0”, and then copy this shortcut file to the directory “PIHM-lab” (our lab root directory).

Clicking the shortcut will bring up the Quantum GIS (QGIS) window, as shown Figure 1. Click “X” to close QGIS.

Figure 1 the QGIS 0.8 preview version interface coming with the PIHMgis. Note, the interface might be shown in different language if your computer locale is not set to English.

3. Create a directory “lab3.shale.hills” under “PIHM-lab”. Extract “shale.hills.pihmgis.data.zip” to the “lab3.shale.hills” directory.

4. Extract qgis.1.0.zip to the directory “PIHM-lab”, go to “qgis.1.0bin”, make a shortcut “qgis” for qgis.exe under this folder, and then copy this shortcut to the directory “PIHM-lab”. Click the qgis shortcut to open it, making sure it can work. It looks like Figure 2.
