#Xnview Mp Versus Xnview How To Do This

In the question What are the best image viewers for Windows. When comparing XnView vs ImageGlass, the Slant community recommends XnView for most people. It is licensed as freeware for private, educational and non-profit uses.20 3. It comes with built-in hex inspection, batch renaming and screen capture tools. XnView is an image organizer and general-purpose file manager used for viewing, converting, organizing and editing raster images, as well as general purpose file management.

As a matter of policy, be willing to accept a slight 'fuzziness' in the appearance of your thumbnails.Assure the best storage environment for your databases reducing the amount of Input/Output Operations from/to database/disk, dramatically improving the speed.Be conservative with the size of the stored thumbnails.XnView MP can dynamically (and temporarily) resize the thumbs to fit which ever thumb size you select using the browser thumbnail sizer, but without changing the stored size. keeping the thumbs database as small as is practical, hence enabling MP to keep much more of it in memory (which means quicker thumbs display). When correlated with issues related to page overflow) can be of huge importance to: This mean means that a typical 30% gain in compression from JPG to WebP (esp. Here are some hints for making the most of this fine software.From a technical perspective, the stored size of each thumbnail bitmap can be quite close to the Operating System sector size (for example: 4K) and very close to XnView MP's DB page size (8K).

When this happens, the time to retrieve a certain info from the database increases (sometimes a lot) because of 1) disk fragmentation - the disk head will need to jump from sector to sector to find the requested info and 2) pointer / page fragmentation: the program needs to jump from page to page in the disk cache maintained in memory (because of a -very- deep chain of pointers traversed frequently) in order to locate and retrieve the desired record / index bucket.That's why DB engines have a feature (usually called VACUUM or COMPACT) which freezes the current DB, copies the entire content to a new, entirely contiguous file (which is, of course, 'ok'), deletes the old DB, renames the new DB to the old name and connects to it. A Cataloged file is a Scanned file for which an user has added information (information = data with human meaning): color, rating, keywords/categories, tags/albums, user comments (& other human generated IPTC), etc.So, Cataloged = Scanned + User Entered InformationKeep the above terms in mind when you read the descriptions below.Because of the way the operating system maintains disk storage, over time the MP database files can become fragmented into several pieces stored in different locations on the drive. A Scanned file is the a file which is added to (entered into) the database by the (automatic) subsystem which builds the thumbnails and enters all the basic (meta)data about the said file: name, directory, EXIF, machine-generated IPTC etc. Periodically optimize your Database: See the next section for how to do this.First, however, it is important to understand the notion of cataloged vs scanned If you can, have the two databases themselves (xnview.db and thumbs.db) each on separate drives - this will speedup access. Try to put the databases on a secondary (non-busy) drive (not the drive with the operating system on it).

If, however, the user has recently deleted many previously scanned image files but has left the folder hierarchy essentially intact, removing the orphaned thumb entries can have a substantially positive effect both on thumb display behavior and database size. Nevertheless, removing them can be very efficient in maintaining database performance and the speed at which the thumbnails appear in the Browser.The same principle from 'Check for orphaned directories' applies here but the process is much slower and less efficient. Or perhaps the folder has simply been relocated elsewhere.Each missing directory situation may need to be examined for cause, so show great care when dealing with orphaned directories. Perhaps it is on removable media (which has been removed!), or maybe the connection to its server volume has failed, or the user doesn't have rights to view the folder anymore. As an important caution, always consider why a folder might be missing from the file system.
