This is a multi-featured drawing program for the CPC464, but will work on the CPC664 if the cassette commands are changedfordisks.Thecursorisdisplay-ed as a cross on the screen. Also shown is a flashing dot known as the fixed point (FP); this point is used as a centre for some of the drawing routines. To move it to the cursor position, press ENTER. At the bottom of the screen is a status line which shows the following information: - X — the X coordinate of the cursor.
- Y — the Y coordinate of the cursor.
- S — the cursor speed (1,2 or 3).
- G — gives the graphics print mode (normal, X-or, or, and).
- P — current pen number (0-15).
- R — gives information on the reference points (up to four). A square in place of any of the numbers indicates that the reference point is in use.
Controls - Cursor keys — move the cursor.
- ENTER — moves the FP to the cursor.
- S — changes cursor speed.
- G — changes graphics print mode.
- R & (1,2,3 or 4) — sets a reference point to the cursor position.
- DEL & (1,2,3 or 4) — sets a reference point.
- 1,2,3 & 4 — moves the cursor to the corresponding reference point.
- CTRL S — saves screen to tape.
- CTRL L — loads in previously-saved screen.
- CTRL CLR — clears the screen.
- A — abort: used to escape from various routines (for example, the airbrush).
- P — replaces the status line with the colour palette. The left/right cursor keys can then be used to select the desired PEN. To change the ink, press C and use the up/down cursor keys to select the ink, followed by ENTER. Pressing R will reset the inks to their initial state. Press ENTER when finished with the palette.
- SHIFT—displays the command line. To select a function, position the cursor under the appropriate symbol and press ENTER while still holding down SHIFT.
Functions available on command line - Line — draws a line from the FP to the cursor. The FP is also moved to the cursor so that other lines can be drawn from the end of the last one.
- Circle—draws a circle with thecentre at the FP and the cursor on the circumference. There is an option to draw the circle filled. Press A to abort without drawing anything.
- Ellipse — draws an ellipse centred on the FP, such that the cursor lies at the end of the major axis. You must enter the ratio of major-to-minor axis times 100, so that entering 100 will draw a circle. To draw the ellipse filled in, precede the ratio with the letter J. If you only want to draw a section of the ellipse (an arc), enter the ratio as a negative number. You then enter the start and finish angles in degrees; these are measured in an anticlockwise direction from the line joining the FP to the cursor. Entering a ratio of 0 will return without drawing anything.
- Arc — this draws an arc from the FP to the cursor over an angle which you enter. A negative angle will draw the arc in the other direction. Entering an angle of 0 will return without drawing anything.
- F — fills an enclosed area which contains the cursor. Press A to stop at any time.
- T—allows you to put text on the screen until you press ENTER.
- R — switches on rubber band mode. A line is dragged around the screen between the cursor and the FP. Pressing ENTER sets the line, while A erases it and returns to normal.
- A — calls the airbursh routine. The cursor is now displayed as a square covering the spray area. Use SHIFT and cursor left/right to change the area. ENTER starts/stops spraying. F fills the area with the current pen colour. A returns to normal.

Page créée en 339 millisecondes et consultée 991 foisL'Amstrad CPC est une machine 8 bits à base d'un Z80 à 4MHz. Le premier de la gamme fut le CPC 464 en 1984, équipé d'un lecteur de cassettes intégré il se plaçait en concurrent du Commodore C64 beaucoup plus compliqué à utiliser et plus cher. Ce fut un réel succès et sorti cette même années le CPC 664 équipé d'un lecteur de disquettes trois pouces intégré. Sa vie fut de courte durée puisqu'en 1985 il fut remplacé par le CPC 6128 qui était plus compact, plus soigné et surtout qui avait 128Ko de RAM au lieu de 64Ko. |
