Enable font-based adjustment of default both dimensions.

Initialize only, BOOL, default FALSE. No local setter or getter.

For a prepared image, AskMinMax multiplies the accumulated default both

dimension(s) by integer font XSize/8 or YSize/8 on each selected axis.

Division occurs before multiplication, so a font dimension below eight

produces a zero factor. Minimum and maximum are unchanged. This is not

an aspect-ratio or pixel-resampling guarantee. Combined and per-axis

tags update the same flags in tag order; the rule does not apply to

OldImage or private Prop-image sizing.

Enable font-based adjustment of default height dimensions.

Initialize only, BOOL, default FALSE. No local setter or getter.

For a prepared image, AskMinMax multiplies the accumulated default

height dimension(s) by integer font XSize/8 or YSize/8 on each selected

axis. Division occurs before multiplication, so a font dimension below

eight produces a zero factor. Minimum and maximum are unchanged. This is

not an aspect-ratio or pixel-resampling guarantee. Combined and per-axis

tags update the same flags in tag order; the rule does not apply to

OldImage or private Prop-image sizing.

Enable font-based adjustment of default width dimensions.

Initialize only, BOOL, default FALSE. No local setter or getter.

For a prepared image, AskMinMax multiplies the accumulated default width

dimension(s) by integer font XSize/8 or YSize/8 on each selected axis.

Division occurs before multiplication, so a font dimension below eight

produces a zero factor. Minimum and maximum are unchanged. This is not

an aspect-ratio or pixel-resampling guarantee. Combined and per-axis

tags update the same flags in tag order; the rule does not apply to

OldImage or private Prop-image sizing.

Allow image width to use the backend size range.

Initialize only, BOOL, default FALSE. No local setter or getter.

TRUE adds backend minimum/default/maximum values on this axis to the

corresponding superclass fields. FALSE adds the backend default to all

three fields. It does not override the separate OldImage or private

Prop-image size paths. Drawing passes actual content dimensions to the

backend; this attribute controls size negotiation, not a generic scaling

algorithm.

Allow image height to use the backend size range.

Initialize only, BOOL, default FALSE. No local setter or getter.

TRUE adds backend minimum/default/maximum values on this axis to the

corresponding superclass fields. FALSE adds the backend default to all

three fields. It does not override the separate OldImage or private

Prop-image size paths. Drawing passes actual content dimensions to the

backend; this attribute controls size negotiation, not a generic scaling

algorithm.

Supply a classic Intuition Image.

Initialize only, struct Image pointer. Default NULL. No local setter or

getter.

The Image structure and referenced data remain caller-owned and must

stay valid while used. It is used only if no prepared specification or

private Prop image takes precedence. Its Width/Height fix size

negotiation; drawing uses DrawImage with no state parameter. Image_State

does not select an alternate old image.

Supply or retrieve the image specification.

Initialize, set and get in this AROS implementation; the header marks

initialize-only. Supply a valid NUL-terminated specification or

supported numeric MUII identifier.

The stored representation is an owned string. Get returns a borrowed

pointer valid until replacement or disposal. No explicit constructor

default is supplied. Set frees before copying, so its input must not

alias the current allocation. When set up it hides/cleans/rebuilds/shows

resources as applicable, updates FillArea for successfully parsed

gradients versus other images and requests full redraw without relayout.

Failed duplication or preparation is not separately reported.

Choose the image drawing state.

Initialize and set, LONG, default IDS_NORMAL. No local getter.

Passed to the image-spec drawing backend or internal Prop-image

renderer. A changed explicit State requests full redraw. Selected TRUE

maps state to IDS_SELECTED; Selected FALSE maps it to IDS_NORMAL on set.

Constructor Selected FALSE does not reset a state already supplied. Tag

order therefore matters. No validation of state values is performed;

classic OldImage drawing ignores the value.

Area.mui

Display a Zune image specification or a borrowed classic Intuition

Image. No source is required at construction; there is no default image

fallback. A prepared specification takes precedence over OldImage. The

class owns a copied specification and setup-time image resources;

OldImage and the internal Prop connection remain borrowed. Complete Hide

and Cleanup before disposal, which frees only the specification string

locally.

Setup calls Area and returns success even if image preparation fails.

For gradient specifications it sets FillArea FALSE; for other

successfully prepared specifications it sets FillArea TRUE. Initial

brush setup removes the frame. These are side effects on inherited

attributes, not merely image-local state.

AskMinMax obtains the prepared image's bounds. A free axis uses its

minimum/default/maximum contributions; a nonfree axis adds its default

size to all three fields. Font matching multiplies only the resulting

default dimension by integer font-size/8. It does not scale minimum or

maximum dimensions. OldImage instead fixes all dimensions to its size

plus superclass minimum contributions. With no usable image, no local

size contribution is added.

Spec replacement is implemented despite the header's initialize-only

annotation. It rebuilds resources when set up and requests redraw, but

no relayout. Image_State changes request redraw; Selected updates map

state to IDS_SELECTED or IDS_NORMAL. Draw normally calls Area, checks

full/update flags and draws the image over the content rectangle.

OldImage uses DrawImage and does not receive state. Show always returns

one after calling Area, Hide and Cleanup return superclass results, and

Dispose returns zero.

Spec strings use AROS's image-specification parser. Supported numeric

MUII identifiers are converted to copied strings: configuration

identifiers in [MUII_WindowBack, MUII_BACKGROUND) use the 6: form,

pattern identifiers in [MUII_BACKGROUND, MUII_LASTPAT) use the 0: form.

Other values are treated as string pointers. Do not assume integer zero

is a NULL-image sentinel.

Repeated constructor Spec tags leak earlier copies. Set frees the

previous specification before duplicating its argument; do not pass the

current getter pointer or an interior pointer back to Set. Duplication

failure loses the old specification and is not separately reported.

Resource getters and borrowed external images do not extend their

owners' lifetimes.
