Imaging Software Glossary: Terms & Concepts: T
The imaging software glossary provides definitions for document and web imaging, in addition to terminology specific to Snowbound Software’s imaging technology.
| text extraction | Text extraction is the ability to extract (pull out) text from a document or image. Snowbound Software's RasterMaster Imaging SDKs support extraction of both text and formatting data from MS Word, Excel, PDF, AFP, and PCL files. The extracted information can be used to create a data stream that can be processed by content aggregation tools to directly import the information into a database or repository. This data is then available to be re-purposed for publishing, archiving, or searching. Batch extraction eliminates old-fashioned manual processes of cutting and pasting information, thereby greatly reducing the amount of time it takes to gather and populate databases with document content. In addition to the large time savings, it also reduces the potential for errors since the content is automatically extracted without manual intervention. |
| Thin Client | A thin client is a computer (client) in client-server architecture networks which has little or no application logic, so it has to depend primarily on the central server for processing activities. The word "thin" refers to the small boot image which such clients typically require. This is perhaps no more than what is required to connect to a network and start up a dedicated web browser. Snowbound's VirtualViewer: HTML is an example of a thin-client. All of the image processing is done on the server and then rendered to the client. |
| Thumbnail | A thumbnail is a small, typically low resolution representation of an image. It is usually used to display many images on the screen at once. It is intended to make it easier and faster to look at or manage a group of larger images. Thumbnails are reduced-size versions of pictures, used to make it easier to scan and recognize them, serving the same role for images as a normal text index does for words. Visual search engines and image-organizing programs normally use them, as can some modern operating systems or desktop environments, such as Windows XP, KDE, and GNOME. |
| Transparency | Transparency displays the foreground color of an image and ignores the specified background color. It is commonly used for icons in Internet HTML documents. In Snowbound's products, transparency is currently supported for the GIF file format. |
| True Color | True color defines each pixel in terms of its actual RGB or CMYK values. Colors in the palette are referenced by index numbers which are used by the computer to identify each color. |
| TWAIN | TWAIN lets you scan an image directly into the application. The TWAIN driver runs be tween an application and the scanner hardware. TWAIN usually comes as part of the software package you get when you buy a scanner. It is also integrated into many image manipulation programs. TWAIN scans an image on the currently installed scanner or input device and returns the standard library image. Snowbound's RasterMaster SDKs support TWAIN Scanning. |
