![]() Images are defined as files containing location (X and Y) and colour values. ![]() Values are typically interpolated to create a regular and smoothly sampled representation of the locations and data. Grids are defined as files containing location (X and Y) and data (Z) values. Basic Differences between Grids and Images As a result, vector graphics are the best choice for type (especially small type) and bold graphics that must retain crisp lines when scaled to various sizes for example logos.īecause computer monitors represent images by displaying them on a grid, both vector and bitmap images are displayed as pixels onscreen. The Oasis montaj CAD drawing tools (licensed version) enable you to draw vector lines and shapes.Ī vector graphic is resolution independent – that is, it can be scaled to any size and printed on any output device at any resolution without losing its detail or clarity. ![]() Vectors describe graphics according to their geometric characteristics. wmf) made of lines and curves defined by mathematical objects called vectors. Vector Imagesĭrawing programs such as AutoCAD create vector graphics (.dxf. As a result, they can appear jagged and lose detail if they are scaled onscreen or if they are printed at a higher resolution than they were created for. Each pixel in a bitmap image has a specific location and colour value assigned to it.īitmap images are resolution dependent – that is, they represent a fixed number of pixels. jpg) are created from a series of pixels to represent graphics. There are two types of images in Oasis montaj: raster images and vector images. To learn more, see the Tutorial for Geosoft GX Developer for Grids and Images. You can learn how to write and process grid files directly with GX Developer – the Geosoft GX API developed to create stand-alone programs that read and/or write to Geosoft supported file formats. Geosoft grid files are made up of straight binary data.
