NetSlide is Shareware. Web address: http://www.archserver.unige.it/caadge/ao/homeao.htm The recent popularity of Internet, and of the Browser like Netscape, has done that a big quantity of persons want show the own works in this new form. The formats graphics supported by Netscape and by the other Browser is prevalently BITMAP, that is the image has stored as a lot of PIXEL. This goes very well for the photos and the drafts realized with Bitmap computer program, like the Paint Brush, but is decidedly uneconomic for all the drawings of vectorial type. In particular Architects and Engineers have represented their plans with images always "vectorial," this also before the PC give a peculiar meaning to the "vectorial" word. Michelangelo asserted that he considers very much the sketch, while the paint of filling is a very simpler thing and of minor importance, amazing declaration for that which we consider a teacher of the paint. Klee speaking about a his "line" told that it had cost him ten years of researches. The Art Noveau took by the "line" the same reason of his existence, and it theorized the communicative and expressive energy of it, with the persuasives demonstrations to all well notorious. Oddly the expands initial of Internet has neglected the aspects of "line," in favor of most immediate and apparently spectacular BITMAP, but the bitmap images behaves a series of problem and disadvantages. Transmit a borne as Vectorial sketch in terms of BitMap by means of Internet is decidedly disadvantageous, it suffices think that a simple line which cross the screen in diagonal, on an ordinary VGA monitor, might be memorized in vectorial format with only two points: P1 (0,0) P2 (640,480) For transmit the same line in Bitmap format it is instead necessary transmit all the information for each point of the rectangle that contains it, that is: 640x480= 307.200 Points Therefore the Vectorial transmission would be of only 4 bytes, while that Bitmap would require 307.200 bytes. A Bitmap image could not be magnified, without a parallel loss of resolution and of quality, while an vectorial image could be magnified how much times are wanted, maintaining a good resolution always. Oddera NetSlide World Wide Web Slide Viewer resolves the problem of Architects and Engineers finally, and of how many anything else has necessity of show sketch and vectorial drawings on Internet. The used format from NetSlide is Autocad Slide, draws aside compact to can be almost considered an algorithm of compression rather than a format, in fact coincident points of more lines comes assembled in a single point, and to their turn bundled in the byte of various order of an single number.
