Thermal Imaging Cameras

Often the question arises: What should be used, raster to vector format? We hope that the following comparison between the two systems will give you some general information on this topic.

Raster Image – as the sum of pixel format. At present, there is a dominant mode of following the presentation) of information (screen graphics display and printer. You can also save a narrow view of the bitmap (bitmap) – Raster-memory or on. Raster image is hard function Indeed, is the size of the compressed file and then loading rate, regardless of the complexity of the image. The advantage of the network is a simple, and then the bit representation of images quickly, in terms of raster imaging devices, or spectators. The limitation of this type of image is that  ‘t intentionally reduced because of the decrease in size can lead to the loss of a few columns of pixels, but always accompanied by the extension of the pixel size. grid image type the memory of graphic images to be useful both very efficient algorithms to reduce the storage of raster data has been developed.

Vector – Image with the help of separate lines, straight lines or curves formed. Vector Imaging quality is a matter of accuracy (it is called the device supports Vector tracer images, displays or vector) graphics primitives and supports basic nomenclature (lines, arcs, curves, ellipses, etc.). The main advantage of vector graphics is a level of comfort with the opportunity to work on the details of elements of different sizes on a screen. Furthermore, the advantage of vector graphics, which in a model that can describe the color and spatial position of objects by mathematical formulas. It provides a relatively small image file and the independence of the dissolution of the printing device or display. For the vector representation of images, the software is usually required relatively complicated and does not understand the true record of all commands ordinariness of files stored in a format vector graphics. At the same time, the more difficult files larger image and more each time the image is drawn.

Vector image has a number of advantages over raster drawings. The main advantages are:

Vectorization – Convert a raster to vector representation. In most cases, this surgery involves the loss of information on the various elements of the program  ‘t describe it correctly (in particular a set of curves is deliberately kept to a minimum). Each reverse process is raterisation. Technically, this operation is simpler than vectorization, but you lose the ability to scale deliberately created the image.
