Custom points are drawn in the same way as standard points and take the same parameters.

Custom Point Renderer
Syntax
cam
Copy
RENDER '[' filter{,filter}[:"<country>"{,"<country>"}] ']', symbol[, render_behavior][, label [, position][, render_behavior]]
Example
cam
Copy
RENDER [group == urgent], BOX<PEN<!black,1>,BRUSH<!white>>, ALWAYS_RENDER, LABEL<!myfont>, ON_SYMBOL, ALWAYS_RENDER
RENDER [all:"Uruguay"], DOT<round,10,BRUSH<(40,0,0)>,BRUSH<!red>>, ALWAYS_RENDER
Note Note

You will likely want to set the colname for any Label objects. This will default to "name" if you do not specify it.

Caution note Caution

If no label is specified and there is no ALWAYS_RENDER on the symbol, the point feature will not be drawn at all. So, if you wanted to render symbol and label only if there is space for both, you need to omit both ALWAYS_RENDER parameters, but specify a label.

Parameters

filter

One or more of the point type filters.

country

An optional list of countries, separated by commas. Country names should match those in the Country enumeration, and should be listed in quotation marks. This argument limits the rendering performed by this statement to the countries specified. If no countries are specified, then the statement will render for all countries which were not matched by earlier statements.

symbol

The symbol to draw. This can be an Icon, Box, Dot, Circle, or Square object, with parameters specified within angle brackets (<>). This can also be NULL, if you want to specify a label only.

label

The label to draw with the symbol. This is optional.

position

Specifies whether the label should be drawn on the symbol, or beside it, by specifying ON_SYMBOL or BESIDE_SYMBOL, respectively. Optional, defaults to BESIDE_SYMBOL.

render_behavior

The first ALWAYS_RENDER parameter specifies whether the symbol (icon, box, or dot) should be drawn if there is not enough space. The second ALWAYS_RENDER parameter specifies whether the label should be drawn if there is not enough space. These options are possible:

  • <symbol>, ALWAYS_RENDER, <label>, ALWAYS_RENDER - If you specify ALWAYS_RENDER for both symbol and label, symbol and label are rendered even if there is not enough space.
  • <symbol>, ALWAYS_RENDER - If you specify a symbol with ALWAYS_RENDER and no label, only the symbol is rendered.
  • <symbol>, ALWAYS_RENDER, <label> - If you specify a symbol with ALWAYS_RENDER and a label without ALWAYS_RENDER, the symbol is always rendered and the label is rendered only if there is enough space.
  • <symbol>, <label> - If you specify a symbol and label, both without ALWAYS_RENDER, symbol and label are rendered only if there is space for both.
  • <symbol>, <label>, ALWAYS_RENDER - If you specify a symbol without ALWAYS_RENDER and a label with ALWAYS_RENDER, the label is always rendered and the symbol is rendered only if there is enough space.
  • <symbol> - If you specify a symbol without ALWAYS_RENDER and no label, the symbol is not rendered at all.

Optional, defaults to rendering symbol and label only if there is enough space.
