PRJID/N/K,WEDGENAME,PORTNAME/K,SELECTUP/S,SELECTDOWN/S,MOUSEMOVE/S,DELAYMOUSEMOVE/K/N,RAWKEY/K,PROJECTACTIVE/S,PROJECTINACTIVE/S,DISPLAYPROJECT/S

Insert a 'wedge' into the input event stream. A wedge is a script that is called every time the specified event occurs. When a wedge has been inserted no input events are passed to the currently active plugin.

Each project may have it's own wedge but only one wedge is possible per project, inserting a new one will remove the previous one.

Calls to the wedges are made asynchronously so that the wedge scripts may in term call other SketchBlock ARexx commands. You must be aware though that in a multitasking environment scripts may not be executed ot finsih executing in strictly the same order they were launched.

Wedge scripts will be called with the arguments:

PRJID <ID>>EVENTNUMBER <unique number> <eventtype> [<eventdata>[...]]

For example for the selectdown event:

sketchblock:Rexx/wedge_lines.rexx  PRJID 42 EVENTNUMBER 1234 SELECTDOWN MOUSEX 123 MOUSEY 456

When a wedge has been inserted into a project '[W]' will be added to the start of the window title.

PRJID/N/K

Specify the project to wedged, if this option is omited the currently active project is used

WEDGENAME

The name of the wedge script to insert. This must be a fully qualified script name, that is visible to ARexx. Call with no name to remove the existing wedge and reenable normal event processing.

PORTNAME/K

If present this is a port based wedge, The ARexx specified by name must exist. Rememebr portnames are case sensitive.

SELECTUP/S

The wedge wants to listen to SELECTUP (LMB released) events. Data will passed as

 SELECTUP MOUSEX <mouse x value> MOUSEY <mouse y value>
 

SELECTDOWN/S

The wedge wants to listen to SELECTDOWN (LMB pressed) events. Data will passed as

 SELECTDOWN MOUSEX <mouse x value> MOUSEY <mouse y value>
 

MOUSEMOVE/S

The wedge wants to listen to MOUSEMOVE events. Data will passed as

 MOUSEMOVE MOUSEX <mous x value> MOUSEY <mouse y value>
 

There will likely be alot of these so the script will need to be short. It's recomended to only use this option if you must get all of the mouse movement information.

DELAYMOUSEMOVE/K/N

The wedge wants to listen to a reduce number of MOUSEMOVE events. Data will passed as

 DELAYMOUSEMOVE MOUSEX <mous x value> MOUSEY <mouse y value>
 

The parameter for this option is the number of events to skip.

RAWKEY/K

Listen to rawkey events.

 RAWKEY CODE < Keycode > QUALIFIER < qualifier >

• "Posterise": replace the colours in a layer with the closest from the provided palette.
  • LONG - ID of palette, 0 for current palette.
• "Julia": generate Fractal images based on Julia sets.
  The Fractal image generated are based on the equation f(z) = z * z + c, where z = x + iy and c is complex. If that maths is two 'complex' for you, all you need to know is that the two numbers REAL and IMAGINARY should vary in a range of + or - 2 and determine what the pattern looks like. The image uses the current foreground and background colours.
  • LONG - Centre X
  • LONG - Centre Y
  • FLOAT - SCALE - Zoom in or out on the fractal image.
  • FLOAT - REAL - Real part of c.
  • FLOAT - IMAGINARY - Imaginary part of c
  • ULONG - Max iterations
• "Unsharp": An UnsharpMask type filter.
  
  • FLOAT - Contrast - The increase in contrst of the edge pixels. Useful Values between 1.0 and 4.0. Values < 1.0 actually soften!.
  • FLOAT - Radius - The Radius or sigma value of the blur kernel that creates the unsharp mask.
  • FLOAT - Threshold - The threshold at which replacement of the pixels occurs, values between 0.0 and 1.0 but generally should be low in 0.1 region.
• "Gaussian": A simple gaussian blur.
  
  • FLOAT - Radius or sigma value for the guassian kernel, larger is more blurring but slower
• "BiLateral": A bilateral filter
  Uses both the spacial distance and colour distance to create a smoothing function with better edge preservation.
  • FLOAT - Radius - Radius or sigma value for the guassian kernel, larger is more blurring but slower
  • FLOAT - Colour Factor - the rate of fall of pixels colour, larger gives sharper edges.
• "Erase": Erases the layer,
  

  This means for a layer with alpha the pixels alpha are set to 0.0 and for layer without alpha they are set to the current background colour.

  Intended to be used in conjunction with selection masks to erase areas of the image.
