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. |
