clip.spad line 1 [edit on github]

The purpose of this package is to provide reasonable plots of functions with singularities.

- clip: (Plot, Fraction Integer, Fraction Integer) -> Record(brans: List List Point DoubleFloat, xValues: Segment DoubleFloat, yValues: Segment DoubleFloat)
`clip(p, frac, sc)`

performs two-dimensional clipping on a plot,`p`

, from the domain Plot for the graph of one variable`y = f(x)`

; the fraction parameter is specified by`frac`

and the scale parameter is specified by`sc`

for use in the clip function.

- clip: List List Point DoubleFloat -> Record(brans: List List Point DoubleFloat, xValues: Segment DoubleFloat, yValues: Segment DoubleFloat)
`clip(ll)`

performs two-dimensional clipping on a list of lists of points,`ll`

; the default parameters`1/2`

for the fraction and`5/1`

for the scale are used in the pspadfun{iClipParametric} subroutine, which is called by this function.

- clip: List Point DoubleFloat -> Record(brans: List List Point DoubleFloat, xValues: Segment DoubleFloat, yValues: Segment DoubleFloat)
`clip(l)`

performs two-dimensional clipping on a curve`l`

, which is a list of points; the default parameters`1/2`

for the fraction and`5/1`

for the scale are used in the pspadfun{iClipParametric} subroutine, which is called by this function.

- clip: Plot -> Record(brans: List List Point DoubleFloat, xValues: Segment DoubleFloat, yValues: Segment DoubleFloat)
`clip(p)`

performs two-dimensional clipping on a plot,`p`

, from the domain Plot for the graph of one variable,`y = f(x)`

; the default parameters`1/4`

for the fraction and`5/1`

for the scale are used in the clip function.

- clipParametric: (Plot, Fraction Integer, Fraction Integer) -> Record(brans: List List Point DoubleFloat, xValues: Segment DoubleFloat, yValues: Segment DoubleFloat)
`clipParametric(p, frac, sc)`

performs two-dimensional clipping on a plot,`p`

, from the domain Plot for the parametric curve`x = f(t)`

,`y = g(t)`

; the fraction parameter is specified by`frac`

and the scale parameter is specified by`sc`

for use in the pspadfun{iClipParametric} subroutine, which is called by this function.

- clipParametric: Plot -> Record(brans: List List Point DoubleFloat, xValues: Segment DoubleFloat, yValues: Segment DoubleFloat)
`clipParametric(p)`

performs two-dimensional clipping on a plot,`p`

, from the domain Plot for the parametric curve`x = f(t)`

,`y = g(t)`

; the default parameters`1/2`

for the fraction and`5/1`

for the scale are used in the pspadfun{iClipParametric} subroutine, which is called by this function.

- clipWithRanges: (List List Point DoubleFloat, DoubleFloat, DoubleFloat, DoubleFloat, DoubleFloat) -> Record(brans: List List Point DoubleFloat, xValues: Segment DoubleFloat, yValues: Segment DoubleFloat)
`clipWithRanges(pointLists, xMin, xMax, yMin, yMax)`

performs clipping on a list of lists of points,`pointLists`

. Clipping is done within the specified ranges of`xMin`

,`xMax`

and`yMin`

,`yMax`

. This function is used internally by the pspadfun{iClipParametric} subroutine in this package.
