Bitmap indexes are ideal for decision support systems (Decision Support SYSTEM,DSS) and data warehouses that should not be used for tables accessed through transactional applications. They can access very large tables using columns that are less than the medium cardinality (number of different values). Although bitmap indexes can reach up to 30 columns, they are usually used only for a small number of colum

Because my computer is very bad, so the general picture processing I can only rely on fireworks (and is 4.0). Because can not use PS to pull hair, so each time only to PS tutorial exclaiming. But I thought for a long while, found that a single background color of the picture is particularly good to dig, the following methods: 1. First, import the bitmap (in the case of a monochrome background only) and name the layer "background". 2. Select the

View Convert to Bitmap Android often encounters situations where a view is converted to bitmap, such as screenshots of the entire screen view and the creation of a picture; in Coverflow, you need to convert one page view to bitmap to achieve complex graphical effects (shadows, reflections, etc.) , such as some dynamic real-time view to facilitate the observation

Compress Bitmap based on the size of the ImageView to avoid OOM and imageviewoom This article is reproduced in: http://www.cnblogs.com/tianzhijiexian/p/4254110.html Bitmap is one of the culprit of OOM. When we download images from the network, we cannot know the exact size of the images. Therefore, to save memory, a thumbnail is usually cached on the server, improves the download speed. In addition, we can

if all items in that block are deleted before they are actually deleted. Ø when the table is modified (UPDATE), the Oracle server actually carries out two operations on the index, one for the logical deletion and the other for the insert operation. After introducing the B-Tree index, we'll start with a bitmap index that describes the structure of another index that may be used frequently in Oracle. 11.4-bit graph index Compared to the B-tree index, i

Most of the indexes we use today are generallyB*treeindex that stores key values and key values in the index structure.RowID,and is one by one corresponds. A bitmap index is primarily created for columns of the same value(Example: category, operator, DepartmentID,WarehouseIDwait),stores key values and starts and ends in an index row of an index blockRowid,and the location encoding of these key values,each of the data rows in the location code that rep

Through internal storage, the bitmap objects are passed between two activity and other Java objects that support serialization, and the key points are as follows: 1. HTTP client downloads picture, displayed by ImageView object 2. The bitmap object on the ImageView is passed from the current activity to another activity and displayed 3. Passing Java object data based on serialization First see how I impl

Bitmap is a very common data structure, such as for Bloom filter, for sorting without repeating integers, and so on. Bitmap are usually based on arrays, and each element in an array can be viewed as a series of binary numbers, all elements constituting a larger binary set. For Python, the integer type is a signed type by default, so the number of available digits for an integer is 31 bits.Bitmap realization

Select the Modify menu, combine paths, merge (Ctrl+j). 9, the full selection of the image, the bitmap for the Mask mask operation: "Modify" menu,

Today, Bitmap is used many times. Bitmap is simply a Bitmap. You need to obtain image resources for some image processing operations.1. Related Concepts 1. Drawable is a printable object. It may be a BitmapDrawable, A ShapeDrawable, or LayerDrawable ), based on the drawing requirements, we can create corresponding printable objects. 2. Canvas, the target area of
