.
The option has effect when reading image data from a file. Specifies
an additional alpha filtering for the overall image, which allows the
background on which the image is displayed to show through.  This
usually also has the effect of desaturating the image.  The
\fIalphaValue\fR must be between 0.0 and 1.0.
.TP
\fBsvg \-dpi\fI dpiValue\fB \-scale\fI scaleValue\fB \-scaletowidth \fI width\fB \-scaletoheight\fI height\fR
.
\fIdpiValue\fR is used in conversion between given coordinates and
screen resolution. The value must be greater than 0 and the default
value is 96.
\fIscaleValue\fR is used to scale the resulting image. The value must
be greater than 0 and the default value is 1.
\fIwidth\fR and \fIheight\fR are the width or height that the image
will be adjusted to. Only one parameter among \fB\-scale\fR,
\fB\-scaletowidth\fR and \fB\-scaletoheight\fR can be given at a time
and the aspect ratio of the original image is always preserved.
The svg format supports a wide range of SVG features, but the
full SVG standard is not available, for instance the 'text' feature
is missing and silently ignored when reading the SVG data.
The supported SVG features are:
.

\fB elements:\fR g, path, rect, circle, ellipse, line, polyline, polygon,
linearGradient, radialGradient, stop, defs, svg, style
.PP
\fB attributes:\fR width, height, viewBox,

is available when Tk is built and run on macOS 10.14 (Mojave) or later.  In
that case the Ttk widgets all support the "Dark Mode" appearance which was
introduced in 10.14. The command accepts the following values for the optional
newAppearance option: "aqua", "darkaqua", or "auto".  If the appearance is set
to aqua or darkaqua then the window will be displayed with the corresponding
appearance independent of any preferences settings.  If it is set to "auto"
the appearance will be determined by the preferences.  This command can be
used to opt out of Dark Mode on a per-window basis.  It may be best to run the "update" command before setting the appearance property, to allow the event loop to run.


- To determine the current appearance of a window in macOS 10.14 (Mojave) and
higher, one can use the command:
  tk::unsupported::MacWindowStyle isdark
The boolean return value is true if the window is currently displayed with the
dark appearance.
