EXPORTFIG 函数的参数
|||
EXPORTFIG Export a figure.
EXPORTFIG(H, FILENAME) writes the figure H to FILENAME. H is
a figure handle and FILENAME is a string that specifies the
name of the output file.
EXPORTFIG(H, FILENAME, OPTIONS) writes the figure H to FILENAME
with options initially specified by the structure OPTIONS. The
field names of OPTIONS must be legal parameters listed below
and the field values must be legal values for the corresponding
parameter. Default options can be set in releases prior to R12
by storing the OPTIONS structure in the root object's appdata
with the command
setappdata(0,'exportfigdefaults', OPTIONS)
and for releases after R12 by setting the preference with the
command
setpref('exportfig', 'defaults', OPTIONS)
EXPORTFIG(...,PARAM1,VAL1,PARAM2,VAL2,...) specifies
parameters that control various characteristics of the output
file. Any parameter value can be the string 'auto' which means
the parameter uses the default factory behavior, overriding
any other default for the parameter.
Format Paramter:
'Format' a string
specifies the output format. Defaults to 'eps'. For a
list of export formats type 'help print'.
'Preview' one of the strings 'none', 'tiff'
specifies a preview for EPS files. Defaults to 'none'.
Size Parameters:
'Width' a positive scalar
specifies the width in the figure's PaperUnits
'Height' a positive scalar
specifies the height in the figure's PaperUnits
'Bounds' one of the strings 'tight', 'loose'
specifies a tight or loose bounding box. Defaults to 'tight'.
'BoundsCode' one of the strings 'internal', 'mcode'
specifies whether to use the internal EPS code or
general m-code for computing bounding boxes. Defaults to
'internal'.
'Reference' an axes handle or a string
specifies that the width and height parameters
are relative to the given axes. If a string is
specified then it must evaluate to an axes handle.
Specifying only one dimension sets the other dimension
so that the exported aspect ratio is the same as the
figure's or reference axes' current aspect ratio.
If neither dimension is specified the size defaults to
the width and height from the figure's or reference
axes' size. Tight bounding boxes are only computed for
2-D views and in that case the computed bounds enclose all
text objects.
Rendering Parameters:
'Color' one of the strings 'bw', 'gray', 'cmyk'
'bw' specifies that lines and text are exported in
black and all other objects in grayscale
'gray' specifies that all objects are exported in grayscale
'rgb' specifies that all objects are exported in color
using the RGB color space
'cmyk' specifies that all objects are exported in color
using the CMYK color space
'Renderer' one of 'painters', 'zbuffer', 'opengl'
specifies the renderer to use
'Resolution' a positive scalar
specifies the resolution in dots-per-inch.
'LockAxes' one of 0 or 1
specifies that all axes limits and ticks should be fixed
while exporting.
The default color setting is 'bw'.
Font Parameters:
'FontMode' one of the strings 'scaled', 'fixed'
'FontSize' a positive scalar
in 'scaled' mode multiplies with the font size of each
text object to obtain the exported font size
in 'fixed' mode specifies the font size of all text
objects in points
'DefaultFixedFontSize' a positive scalar
in 'fixed' mode specified the default font size in
points
'FontSizeMin' a positive scalar
specifies the minimum font size allowed after scaling
'FontSizeMax' a positive scalar
specifies the maximum font size allowed after scaling
'FontEncoding' one of the strings 'latin1', 'adobe'
specifies the character encoding of the font
'SeparateText' one of 0 or 1
specifies that the text objects are stored in separate
file as EPS with the base filename having '_t' appended.
If FontMode is 'scaled' but FontSize is not specified then a
scaling factor is computed from the ratio of the size of the
exported figure to the size of the actual figure.
The default 'FontMode' setting is 'scaled'.
Line Width Parameters:
'LineMode' one of the strings 'scaled', 'fixed'
'LineWidth' a positive scalar
'DefaultFixedLineWidth' a positive scalar
'LineWidthMin' a positive scalar
specifies the minimum line width allowed after scaling
'LineWidthMax' a positive scalar
specifies the maximum line width allowed after scaling
The semantics of 'Line' parameters are exactly the
same as the corresponding 'Font' parameters, except that
they apply to line widths instead of font sizes.
Style Map Parameter:
'LineStyleMap' one of [], 'bw', or a function name or handle
specifies how to map line colors to styles. An empty
style map means styles are not changed. The style map
'bw' is a built-in mapping that maps lines with the same
color to the same style and otherwise cycles through the
available styles. A user-specified map is a function
that takes as input a cell array of line objects and
outputs a cell array of line style strings. The default
map is [].
Examples:
exportfig(gcf,'fig1.eps','height',3);
Exports the current figure to the file named 'fig1.eps' with
a height of 3 inches (assuming the figure's PaperUnits is
inches) and an aspect ratio the same as the figure's aspect
ratio on screen.
opts = struct('FontMode','fixed','FontSize',10,'height',3);
exportfig(gcf, 'fig2.eps', opts, 'height', 5);
Exports the current figure to 'fig2.eps' with all
text in 10 point fonts and with height 5 inches.
