Imaging Software Glossary: Terms & Concepts: O

The imaging software glossary provides definitions for document and web imaging, in addition to terminology specific to Snowbound Software’s imaging technology.


Object Objects are units of code that are eventually derived from a process. An object is what actually runs in the computer. Objects can share models and reuse the class definitions in their code.

Octree Octree is a color reduction algorithm used to reduce the number of colors in an image from 24-bits or 8-bits to 4 or 8-bits. An octree is a tree data structure mainly used for organizing 3-dimensional space.

Orientation Orientation determines which edge of the image is displayed in the positive X direction (up) and which edge is displayed in the negative Y direction (left).

Overlay file When used in imaging, an overlay file is generally text data that when displayed at a fixed position above a blank form fills in the fields for that for m. The form is usually a scanned image. This is most common with MO:DCA and PTOCA images. Snowbound Software's annotation options permit the creation of text and graphic overlays to an underlying image.
