ARTIST2 (RISCOS 3 ONLY) INSTRUCTIONS / HELP NOTATION: Mouse Buttons: {S} = Select , {M} = Menu , {A} = Adjust. Keyboard : <X> = Press key 'X' etc. The screen has three main areas:- (A) The COLOURS SECTION (bottom of the screen) displaying all 256 colours. (B) The TOOLS BAR - to select a drawing tool. (C) The DRAWING AREA (with default background colour of white). We will deal with each of these in turn : (A) The COLOURS SECTION. When the pointer is IN the Colours Section :- 1) Click on {S} to choose a 'pure' colour (the MAIN colour). 2) Click on {A} to choose a 'dithered' partner to the MAIN colour ( the SECONDARY colour). 3) Click and HOLD on {M} to give a Help window on the currently selected tool, Colour Box or when in Text mode. 4) Press and hold <H> to give a general Help window. 5) Press <T> to enter Text mode. This will display text dialogue boxes and enables entry of Text onto the drawing area. The 'MAIN' colour is displayed with a white surrounding rectangle. The SECONDARY colour is displayed with a small bar on top of the chosen colour. The 'MAIN' colour always has precedence. The Colour Box (on the extreme RHS of the Tools Bar) always displays the current pure/dithered colour which is in current use by the various drawing tools. If a dithered colour is in use then the Colour Box displays a dotted line across the colour box. If a pure colour is chosen then no dotted line will be shown. With a given MAIN colour , clicking {A} on any of the remaining 255 different colours gives all the possible dithered colours corresponding to that given MAIN colour. So a total of 32,640 different dithered colours can be chosen! When the pointer is IN the Colours Section (and ONLY then ) the following keyboard keys become active :- (a) <TAB> - Clears the Drawing area ( default white background). (b) <Shift>+<Q> - Quits the program and returns to the Desktop. (c) <S> - Saves the screen to a directory PICS within !Artist+. A screen will be automatically saved to PICS with filenames PIC1,PIC2,PIC3 etc. in succesion, during each session. After each session they should be renamed with more meaningful names ,since restarting the program will cause the filenames to revert to PIC1,PIC2 etc again. <SHIFT>+<S> This brings up a SAVE Screen dialogue box. You will be prompted for the filing system you wish to use (Disc or RAM) and the Root Directory Catalogue will be displayed. A new Directory may then be chosen. Finally you will be asked for the filename of your picture, which will then be saved to the current/new Directory. (d) <L> - Loads a screen from the directory PICS. You will be prompted to input the required filename. <SHIFT>+<L> This brings up a LOAD Screen dialogue box. Follow the prompts as for above. You will be prompted for the filename of the picture, which will then be loaded onto the screen. Additions / alterations may then be made to the picture. (e) Pressing the number keys <1>,<2>,....<6> will choose different mouse speeds. The default value is <3>. <1> is the slowest and allows maximum control. <6> is very fast ( and should be used with care ). (f) If the POLYGON tool is currently chosen then pressing will enable you to type in the number of sides required - only numbers between 3 and 99 are allowed. (g) <T> - Displays a TEXT dialogue box. Press <Y> to make font changes, or any other key to choose the default/current value of font type. Enter your text at the text-prompt, followed by <RETURN>. ( Just pressing <RETURN> retains the current text string ) The dialogue box disappears and a rectangle will appear on the screen. This can be moved around with the mouse and clicking {A} increases the size of the box, while {M} will decrease its size. Clicking {S} on the drawing area will now enter the text within the box at the position of the pointer. The colour of the text will be the current main colour, but this can altered by choosing a new colour from the Colour Bar. If the pointer is on the Colour Bar then {S} will select a text colour (as usual) while {M} gives a Help-Text window. Note: Text can only be painted in one of the main colours - any dithered partner is ignored. Pressing <T> again brings back the font/text dialogue box, so that alterations or new text can be entered. Press <SPACE> to finish. Summary of the active keys during text placement: <Select> = Plot the text, or = Paint the text as a Brush. ( +<Shift> =thick text, +<Alt> = thicker text ) <T> = Re-enter the Font/Text dialogue box to make changes. <L> = Toggle antialiasing | <SPACE> = Abort/Finish | Global magnification = >,< or MOUSE <Adjust>,<Menu> Rotation about the Origin = <Z>,<X> or <A>,<S> for 15° increment X-Stretch = Left,right cursors | Y-Stretch = Up,down cursors | X-Shear = Keypad 1,3 | Y-Shear = Keypad 2,5 | Flip about Width = <W> | Flip about Height/Depth = <D> | Reflection in Vertical = <V> | Reflection in Horizontal = <H> | Reflection in the Origin = <O> | Plot in 12 point circle = <£> | Restore default size = <R> | Clear screen = <Tab> Note:- 'Origin' means the bottom-left of the text string. The 'background' colour used for antialiasing is taken as the screen background colour at the 'Origin',which may not always be suitable if there are numerous colours on screen. NOTE: The following keys are always active :- <SPACE> - aborts the current action (except for the tools FREE and AIR ). <ALT> - toggles between a pointer and a full cross-hair cursor. The latter is useful to align various drawn objects (except for TEXT entry). (B) The TOOLS BAR. NOTE:- some tools have one or two parameters. When the pointer is on the Tools Bar :- (a) Click {S} to select either a tool, or the Colour Box on the extreme RHS. (b) For single parameter tools : {M} will decrement the parameter {A} will increment the parameter. For two parameter tools : (i.e ARC, POLYGON, AIR ) {M} increments the LHS parameter / icon {A} increments the RHS parameter. Note:- If the POLYGON tool is currently chosen then pressing on the keyboard will enable you to input the number of sides required ( from 3 to 99). (C) The DRAWING AREA. When not actually drawing you can still use {M} and {A} to change the parameters ,and <ALT> to toggle between a pointer and a full cross-hair cursor. Also, use {S}+<SHIFT> to pick up a pure colour from the drawing OR use {A}+<SHIFT> to pick up a dithered partner colour. While using a particular tool pressing <SPACE> will abort the current action ( except for the FREE and AIR tools - just release {S} in these cases). ************* Click on {S} to start using any tool. ************* We shall deal with each of the drawing tools in turn : (1) JAGG. This gives a jagged "curve" between any two points. The degree of jaggedness is governed by the parameter.This tool is useful for drawing maps, trees, mountains etc. Use small steps to achieve greater control. Click {S} to start. Moving the mouse will display a dotted line to your 'next' point. Click {S} again to continue to add points - a continuous jagged curve will be displayed which passes through the points in succession. Click {A} to finish with your last point ( with an open path ), OR click {M} to complete a closed path ( to your initial point ). Parameter: 1 = minor variation, 6 = violent variation( use with care!) (2) PARALLELOGRAM. Click {S} to fix a start point. Moving the mouse will display a dotted line. {S} again (or {A}) fixes this side of the parallelogram. Moving the mouse now will display the possible parallelograms with this fixed side. Click {S} again to finish with an outline parallelogram, OR click {M} to get a colour filled parallelogram. Holding {A} down and moving the mouse will move the parallelogram bodily. While still holding {A} down click on {S} for outline, or {M} for a colour filled parallelogram. This enables copies of a parallelogram to be drawn in various positions. (3) ELLIPSE. Click {S} to start. Moving the mouse will display various sized ellipses. Click {S} again to finish with an outline ellipse, OR click {M} to finish with a colour filled ellipse. Clicking / Holding <Z>,<X> on the keyboard will rotate the ellipse anticlockwise / clockwise. Holding <C> down fixes the centre, enabling 'concentric' ellipses to be drawn. Holding {A} down will enable the ellipse to be moved bodily. Clicking on {S} / {M} as well will still give outline / filled ellipses. 'Pretty' patterns can be generated by holding down {A} and <Z> (or<X>) and then clicking rapidly/holding on {S} (or{M}). (4) ARC. This tool enables smooth curves (open or closed) to be drawn through various points. The R.H parameter adjusts the width of the curve :- 1 = thinest line curve,...,6 = thickest line curve (default=1) Click {S} to start. Moving the mouse will display a dotted line. Click {S} again to continue to add points - a smooth curve will be drawn continuously through the succesive points. Click {A} on the last point to finish with a smooth open curve, OR click {M} to finish with a smooth closed path (to your initial point ). Note: the first 'branch' is not finalised until the final {A} or {M}. (5) CIRCLE. Click {S} to start. Moving the mouse displays various sized circles, centered on the initial point. Click {S} again to finish with an outline circle, OR click {M} to finish with a colour filled circle. Holding <C> down enables concentric circles to be drawn. Holding {A} down will enable the circle to be moved bodily. Clicking on {S}/{M} as well will still give outline / filled circles. (6) FREE. This is a freehand drawing tool. Press the number keys <1>,...,<5> to select the speed/smoothness of drawing. The default value is 3. Click {S} to start, and HOLD it down while moving the mouse. This will generate a free-hand curve. The parameter determines the width of the line :- 1 = thinest line ,...,6 = thickest line. Holding keys <H>/<V> will force horizontal/vertical lines. ERASER: - This tool can also be used as an eraser, if the background colour is chosen as the current colour. Holding {S}+<SPACE> will display a small outline circle (for thickness > 3 ) which makes it easier to see with accuracy the area to be deleted. (7) LINE. This tool enables straight lines to be drawn (continuously) in various widths. The resulting polygonal shapes can be open or closed. Click {S} to start. Moving the mouse will display a dotted line. Click {S} again to continue to add points - a continuous path of straight lines through the succesive points will be displayed. Hold keys <H>,<V> to force horizontal / vertical lines. Click {A} to finish with your last point - giving an open path, OR click {M} to complete a closed path to your initial point. The parameter determines the width of the line :- 1 = thinest line,...,6 = thickest line (Note: using small steps will almost generate a smooth curve) (8) FILL. Click {S} to fill an area with the current colour. If the current colour is 'pure' then filling will always work, irrespective of the colour already present in the chosen area. If the current colour is a dithered one then filling will only work if the colour in the area is 'pure'. So to overwrite a dithered area you must first fill the area with a pure colour and THEN refill with your chosen dithered colour. Pressing <SPACE> 'unfills' or 'undoes' the last fill (but only if NO colour changes have been made in the meantime). (9) RECTANGLE (+COPY) Click {S} to start. Moving the mouse displays various rectangles, with one vertex at the initial point. Click {S} again to finish with an outline rectangle, OR click {M} to finish with a colour filled rectangle. Holding {A} down will enable the rectangle to be moved bodily, and clicking on {S}/{M} will still give outline/filled rectangles. Pressing <S> will force the rectangle into a square. Rotation: Pressing <R> ( or <Z>,<X> ) will enter rotation mode. Pressing <Z>,<X> will rotate the rectangle anticlockwise,clockwise. Use the cursor keys to expand/contract its height/width. (Pressing Ctrl+<Z>,<X>,cursor keys will give finer control) The number keys 0,1,2,...,8 will rotate the sprite by that multiple of 45 degrees anticlockwise e.g press <3> to rotate by 135 degrees anticlockwise. (0 and 8 have the same effect of returning to the original orientation) Use <,> to rapidly double/halve the dimensions of the rectangle. Pressing <D> will return the rectangle to its original dimensions. Pressing <S> will force the rectangle into a square. Press to toggle on/off using your rectangle as a brush. Click {S} (or press <O>) for outline rectangles. Click {M} (or press <F>) for colour filled rectangles. Use <SPACE> to finish. COPY Mode:- to make a copy of a chosen area at a different place. This copy can be flipped,rescaled,rotated or used as a brush. Press <Copy> to start COPY mode on the chosen rectangular area ( a sprite area ). A 'beep' sound will occur. Move the area to your desired place and click {S}. A copy of the chosen area will be drawn,leaving the original area intact.This can be repeated as many times as desired. Pressing <H> will give a horizontally flipped copy, while pressing <V> will give a vertically flipped copy of the original sprite area. Use the cursor keys to adjust the width/height of the sprite. Use the <,> keys to rapidly double/halve the dimensions. Press <Z>,<X> to rotate anticlockwise/clockwise. ( Ctrl+<Z>,<X>,cursor keys will give finer control ) Pressing <S> will force the rectangle into a square. Pressing <D> will return the sprite to its original dimensions. ( Press <O> to get outline rectangle in current foreground colour. Press <F> to get a colour filled rectangle. ) Press to toggle on/off the Brush facility. Holding {S} down will then draw with the sprite as a paint brush. The number keys 0,1,2,...,8 will rotate the sprite by that multiple of 45 degrees anticlockwise e.g press <3> to rotate by 135 degrees anticlockwise. (0 and 8 have the same effect of returning to the original orientation) Press <SPACE> (or {M}) to finish Copy mode. NOTE: width,height (and horiz,vertical) may lose their contexts at larger angles of rotation and adjusting these may seem to have the opposite effect to that required. To keep track of this the outline rectangle has little circles on the two 'top' corners. You should regard this edge as the 'top' edge - <H> will always flip about a line parallel to this 'top' edge, while <V> will always flip about a line perpendicular to this 'top' edge. If still in doubt just use the 'opposite' key(s). (10) POLYGON. Click {S} to start. Moving the mouse will display various polygons (or the surrounding ellipse,if the number of sides is large) The L.H icon displays the three 'styles' viz. Outline, Outline with spokes or just spokes. Click {M} to toggle through the various styles. The R.H parameter is the number of sides. When not drawing {A} increments the number of sides (from 3 to 9). Press key to input your own number (from 3 to 99). Click {S} again to finish with a polygon in the chosen style, OR click {M} to finish with a filled polygon (irrespective of style). Holding <C> down enables concentric polygons to be drawn. Hold {A} down to move the polygon bodily. Clicking on {S}/{M} as well will still give the outline / filled polygons. Click or Hold <Z> / <X> to rotate anticlockwise / clockwise. Click <H> to force a regular polygon (i.e inside a circle with the current height). Similarly click <W> for a regular polygon with the current width. Note: 'Pretty' patterns can be formed , as with Ellipse. (11) AIR (SPRAY). L.H.parameter is the density of the spray. Use {M} to increment. A = lowest,...,E = highest. R.H.parameter is the radius of the spray. Use {A} to increment. 1 = least,...,6 = largest. Hold {S} down to spray with fine dots, but ONLY if the pointer is moving. {S}+<SPACE> ( or {S}+{M} or {S}+{A} ) will spray an area even if the pointer is NOT moving. {S}+<D> gives a spray of coarser circular dots ( D = 'Dots'). {S}+<F> gives a spray of angular shapes ( F = 'Foliage'). (<SPACE>,{M} or {A} as well sprays even if the pointer is stationary ). (12) COLOUR BOX. Clicking {S} will pick up the colour from the drawing area which is under the pointer. Clicking {A} will pick up a dithered partner from the drawing area ( it may be necessary to move the mouse a bit in an area containing a dithered colour ). At all stages the current colour (pure or dithered) is shown in the box. SPECIAL EFFECTS (only when the Colour Box is the chosen tool):- Hold {M} down to 'scratch' an area with hues of the colour under the pointer. Hold {M}+<SPACE> to paint with 'blobs' of hues of the colour under the pointer.
