- 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.
