NAME

+fgisRasterColorImage, fgisRasterBWImage - render raster object into +planchet item

+ +

SYNOPSIS

+fgisRasterColorImage raster planchet item ?option +?

+ fgisRasterBWImage raster planchet item ?option ?

+ +

DESCRIPTION

+

+ These +commands perform visualisation of fGIS raster objects in fGIS planchet +(essentially same as Tk canvas). They work on platform independent manner, +creating visible representation of layer in Tk image object, which should +be previously created.

+ User (and even application writer) seldom accesses +this commands directly. Raser layer objects and planchet subcommands should +be used to visualize raster layers.

+ These commands controls all attributes +of layer appearance, which have no semantic meaning. I.e. raster file class +to palette index correspondence is part of raster object, becouse it also +used for access legend and GIS operation, while palette itself appear +only in call to this command, becouse it used only to visualisation.

+ + +

ARGUMENTS

+

+ +

+ +
raster -
+
name of fGIS raster object (see raster (n) +).
+
+

+ +

+ +
planchet + -
+
name of fGIS planchet widget. Planchet should be mapped and have coordinate +system already defined.
+
+

+ +

+ +
item -
+
ID of planchet item to render raster in. +It should exist, be of type image and contain valid image (photo for fgisRasterColorImage + and bitmap for fgisRasterBWImage ) in its -image atribute.
+
+

+ +

OPTIONS

+ +
+ +
-border +option -
+
specifies whether borders between raster object classes or base +file classes (polygon borders) should be drawn. Option can be one of none +, yes , base . Abbreviations are not allowed (bug?). yes means that borders +are drawn only between distinct classes of current raster object, base + means that borders should be drawn if base file classes are distinct, +even if they are reclassed into same value. Useful for choropleth plots. +
+
+

+ For symbol plots option is ignored. Defaults to none for color images +and yes for BW images. +

+ +
-color color
+
- specifies color to plot borders +in color mode or for entire image in pattern or symbol mode. color can +be any form of color specification, acceptable by Tk. Defaults to "black". +
+ +
-map option -
+
specifies how to deal with map classes, which exceed palette +or pattern range (0-255). Option is one of wrap - use symbol (color) class%255 + for classes which exceeds 255, none - use symbol (color) 255 for all +these clases and number - map range 0-max class to range 0-number . Defaults +to wrap .
+ +
-palette palettename (color only) -
+
specifies fGIS palette object +to use for coloring of map classes. Defaults to defaultpalette .
+ +
-patterns +patternname (BW only) -
+
sets plotting mode to pattern and specifies pattern +set to plot. In pattern mode patterns are clipped by polygon boundaries, +and thus any border modes are allowed. Defaults to {} (empty pattern). This +mode is default for fgisRasterBWImage
+ +
-symbols patternname (BW only) +-
+
sets plotting mode to symbol and specifies pattern set to plot. In symbol +mode patterns can be drawn only at whole, so if central point of pattern +belongs to certain class, pattern for this class would be drawn on entire +rectangle. Borders are never plotted in this mode No defaults, becouse +this mode must be turned on explicitely.
+ +
-update {x1 y1 x2 y2}
+
- Specifies, +that only part of image should be replotted. Useful for raster editing +application. Rectangle to update is given in map coordinates. It is clipped +by image boundaries.
