"green" #t 0 96)]
When @racket[str] contains tall letters or @racket[trim?] is @racket[#f], using @racket[height] as the font size should be sufficient.
To make it easy to create a large enough font, @racket[text-icon] always interpets font sizes as being in pixels, never points.
See @racket[font%] for details on font sizes.
If @racket[trim?] is @racket[#f], the drawn text is not cropped before rendering.
Otherwise, it is cropped to the smallest rectangle containing all the non-zero-alpha pixels.
Rendering very small glyphs shows the difference dramatically:
@interaction[#:eval icons-eval
(define font (make-object font% 32 'default))
(list (text-icon "." font "white")
(text-icon "." font "white" #f))]
Note that both icons are @racket[(default-icon-height)] pixels tall.
When @racket[outline] is @racket['auto], the outline drawn around the text is @racket[(/ height 32)] pixels wide.
Because different platforms have slightly different fonts, @racket[text-icon] cannot guarantee the icons it returns have a consistent look or width across all platforms.

@section{Icon Constants and Contracts}
@;{
@doc-apply[icon-colors]{
A list containing the names of allowed icon colors.
When an SVG icon source file is rendered, it is rendered once directly. Then, for each color corresponding to a symbol in @racket[icon-colors], it is colorized by replacing gradients, and then rendered.
When loading an icon, a @racket[#f] color name loads an uncolorized rendering.
Every icon can be loaded with a @racket[#f] color name.
An icon can be loaded using any name in @racket[icon-colors] only if its SVG source has gradients that can be colorized.
See @secref["new-icons"] for details.
The actual hues associated with the color names are the hues of the first seven @racketmodname[plot] color numbers.
The following example illustrates the correspondence:
It is difficult to put a code example in the API documentation that produces an animation.
However, we might use code similar to the following to sample from the run cycle:
@interaction[#:eval icons-eval
(require plot)
(for/list ([color (rest icon-colors)])
(stop-flomap color 48))
(parameterize ([plot-width 48]
[plot-height 48]
[plot-decorations? #f]
[plot-background-alpha 0])
(for/list ([n (in-range 7)])
(plot3d-pict (surface3d (λ (x y) (- (sqr x) (sqr y))) -1 1 -1 1
#:color n #:line-color n
#:samples 11 #:line-width 1))))]
This example also shows how to use @racketmodname[plot] to create icon @racket[pict]s from mathematical functions.
}}
(for/list ([t (in-range 0 1 1/12)])
(running-stickman-icon t run-icon-color "white" run-icon-color 32))]
If instead of putting the icons in a list, we call their @racket[save-file] methods and hand-assemble the files into a GIF, we get something like this:
@doc-apply[icon-color/c]{
A contract that identifies color names.
@centered[@image["scribblings/running-stickman.gif"]]
Here, the run cycle is sampled and played back at 30 Hz.
The previous example samples the run cycle at 12 Hz, or every @racket[1/12] second.
DrRacket samples it at 12 Hz and plays it back at 5 Hz at the most.
The stickman's joint angles are defined by continuous periodic functions, so the run cycle can be sampled at any resolution, or at any real-valued time @racket[t].
The cycle is modeled after the run cycle of the player's avatar in the Commodore 64 game @link["http://en.wikipedia.org/wiki/Impossible_Mission"]{Impossible Mission}.
}
@doc-apply[icon-styles]{
Typical icon styles.
@section[#:tag "tool"]{Tool Icons}
It is not necessary to have a version of each icon in each style.
But if an icon has different styles, it should have these.
}
@doc-apply[icon-style/c]{
A contract that identifies icon styles.
}
@section{Icon @racket[pict]s}
@interaction-eval[#:eval icons-eval (require slideshow/pict)]
It is more flexible, but a little more complicated, to load icons as @racket[pict]s.
As picts, icons can easily be appended, inset, superimposed, blurred, and more.
For example, it is easy to make modern-looking media player controls using @racket[cc-superimpose] and the @racket['shiny] style:
@interaction[#:eval icons-eval
(define media-icon-background (record-flomap 'blue 64 'shiny))
(list (cc-superimpose media-icon-background
(step-back-flomap 'white 32 'shiny))
(cc-superimpose media-icon-background
(pause-flomap 'white 32 'shiny))
(cc-superimpose media-icon-background
(step-flomap 'white 32 'shiny)))]
Almost all of the functions in preceeding sections are defined in terms of the @racket[pict]-producing functions documented in this section.
To use these functions effectively, you should require @racketmodname[icons] and @racketmodname[slideshow/pict] together.
Use @racket[bitmap] to convert a @racket[bitmap%] (e.g. an icon) to a @racket[pict], and @racket[pict->bitmap] to convert back.
Converting from @racket[pict]s to bitmaps can be lossy. For example, converting text can look especially horrible:
@interaction[#:eval icons-eval
(scale (text "Hello" null 10) 5)
(scale (bitmap (pict->bitmap (text "Hello" null 10))) 5)]
Therefore, when composing icons from parts, try to work only with @racket[pict]s, and convert to an icon using @racket[pict->bitmap] as the last step.
When composing icons from parts, it is fine to use @racket[pict]s converted from @racket[bitmap%]s.
Without scaling or rotating, the conversion is lossless:
@interaction[#:eval icons-eval
(define not-blurry (magnifying-glass-icon 64 'shiny))
not-blurry
(for/fold ([icon not-blurry]) ([i (in-range 30)])
(pict->bitmap (bitmap icon)))]
Avoid converting between @racket[pict]s and @racket[bitmap%]s more than once if bitmap-backed @racket[pict]s are scaled, rotated by angles that are not multiples of 90 degrees, or superimposed or appended at non-integer coordinates.
Avoid scaling up in general.
