GM_SetPointFeatureDrawStyle

Sets the symbol and font to use for drawing the given point feature. Pass NULL for the point style to reset the drawing style to the default style for the classification of the point.

Syntax

GM_Error_t32 GM_SetPointFeatureDrawStyle
(
GM_LayerHandle_t32      aLayer,             // Layer the point is in
uint32                  aPointIndex,        // Index of point in layer
const GM_PointStyle_t*  aPointStyle         // New style to use for point
);

Remarks

Typically, when modifying the drawing style of a point you'll want to call GM_GetPointFeature to get the current drawing style, then copy the mPointStyle member of the GM_PointFeature_t and just change what you need, then pass your copy in to this function. You can add new symbols using the GM_AddCustomSymbol function.

There are some custom symbols built in and you can use a string with the following form: ShapeName + "_CUSTOM_" + size_R_G_B.

Example: you if you wanted a red Diamond with a scale of 5 pixels. You would use the string: "DIAMOND_CUSTOM_5_255_0_0"

The built in custom shapes include: DOT, SQUARE, DOT_EMPTY, VERT_BAR, CROSS, DIAG_CROSS, STAR, STAR_EMPTY, TRIANGLE, TRIANGLE_EMPTY, DIAMOND, DIAMOND_EMPTY, SQUARE_EMPTY, HALF_PIE and HALF_PIE_EMPTY.
