Auxiliary Types
Fonts
(make-font &key family size style justification text-color background-color) [function]
Creates a font description that can be used in set-view-font. // TODO: In addition to whatever else we support for family (string? int?) also allow keywords corresponding to meta font constants, e.g. :big-system-font :small-system-font :small-bold-system-font :view-system-font…) //
(font-p object) [function]
Returns true if //object// is a font.
(same-font-p font1 font2) [function]
True if font1 and font2 are the same in all components. // TODO: Or should we intern and let them use EQ?//
(font-family font) [function]
Returns the font family.
(font-size font) [function]
Returns the font size.
(font-style font) [function]
Returns the font style.
(font-justification font) [function]
Returns the font text justification, one of :default, :center, :right or :left.
(font-text-color font) [function]
Returns the font foreground color.
(font-background-color font) [function]
Returns the font background color.
Colors
Note: This is explicit about it being RGB in order to allow extension to support other color spaces in the future.
(make-rgb-color &key red green blue alpha) [function]
Creates a color description for the specified values. // TODO: Accept both floats 0.0-1.0 or ints 0-255?//
(rgb-color-p object) [function]
Returns true if object is an rgb-color.
(same-color-p rgb-color1 rgb-color2) [function]
True if //rgb-color1// and //rgb-color2// are the same in all components.
(color-red rgb-color) [function]
Returns the red component of the color.
(color-green rgb-color) [function]
Returns the green component of the color.
(color-blue rgb-color) [function]
Returns the blue component of the color.
(color-alpha rgb-color) [function]
Returns the alpha component of the color.
Points
(point h v) [function]
Returns a point with horizontal coordinate //h// and vertical coordinate //v//. //h// and //v// can be any real numbers.
(point-p object) [function]
Returns true if //object// is a point.
(point-h point) [function]
Returns the horizontal coordinate of //point//.
(point-v point) [function]
Returns the vertical coordinate of //point//.
(point+ point1 point2) [function]
Returns a point with each coordinate being the sum of //point1// and //point2//.
(point- point1 point2) [function]
Returns a point with each coordinate being the difference of //point1// and //point2//.
(point<= point1 point2) [function]
Returns true if each coordinate of //point1// is <= to corresponding coordinate of //point2//.
(point< point1 point2) [function]
Returns true if each coordinate of //point1// is < corresponding coordinate of //point2//.
(point= point1 point2) [function]
Returns true if each coordinate of //point1// is = to corresponding coordinate of //point2//.
Rectangles
(make-rect &key top left bottom right top-left bottom-right width height size) [function]
Returns a rectangle, specified by either top/left/bottom/right coordinates, or top/left/height/width coordinates, or the top-left/bottom-right points, or top-left/size points.
(rect-p object) [function]
Returns true if object is a rectangle.
(rect-top rect) [function]
Returns the top coordinate of rect.
(rect-left rect) [function]
Returns the left coordinate of rect.
(rect-bottom rect) [function]
Returns the bottom coordinate of rect.
(rect-right rect) [function]
Returns the top coordinate of rect.
(rect-width rect) [function]
Returns the width of rect.
(rect-height rect) [function]
Returns the height coordinate of rect.
(rect-top-left rect) [function]
Returns the top and left coordinates of rect as a point.
(rect-bottom-right rect) [function]
Returns the bottom and right coordinates of rect as a point.
(rect-size rect) [function]
Returns the width and height of rect as a point.
OSTypes
OSTypes are used as identifiers in many Carbon contexts. We do not introduce a special Common Lisp type to represent OSTypes. Instead, all functions that are documented as accepting an OSType will accept any of: a 32-bit integer, or a 4-character string (of 8-bit characters), or a keyword whose symbol-name is a 4-character string (of 8-bit characters).
(ostype-value ostype) [function]
Returns the integer value of ostype.
(ostype-string ostype) [function]
Returns the string value of ostype.
(ostype-keyword ostype) [function]
Returns the keyword value of ostype.
