Overview

LAYER 1..∞
When used in a map file (*.apm), it defines the characteristics of one of the map layers.
brightness optional Restriction of xs:double
Brightness adjustment for the layer. Positive values increase the whiteness of the layer, negative values increase the darkness of the layer.
contrast optional Restriction of xs:double
Contrast adjustment for the layer. Positive values exaggerate color separation (as the value approaches 1, the result is either pure black (for colors below the grey threshold) or pure solid color (for colors above the threshold), for example, a dark red will become pitch black, whereas a bright red will become solid red). Negative values merge/dissolve the colors (as the value approaches -1, the result is all gray).
edit optional Restriction of xs:string
hyperlink optional Restriction of xs:string
identify optional Restriction of xs:string
maxscale optional xs:string
minscale optional xs:string
name optional xs:string

When parent is ToolButton:

Custom tool name. Used to reference the tool in scripts.
refscale optional xs:string
Reference scale to display the TRUETYPEMARKERSYMBOL or SIMPLEMARKERSYMBOL at the specified fontsize using a relative scale such as 1:24000. TRUETYPEMARKERSYMBOLs and SIMPLEMARKERSYMBOLs are scaled relative to the refscale as the map is zoomed in or out.
transparency optional xs:double
transparencycolor optional Restriction of xs:string
Sequence
DATASET
name required xs:string

When parent is ToolButton:

Custom tool name. Used to reference the tool in scripts.
HYPERLINK
Used to specify the hyperlink properties of a layer in an ArcPad layer definition or ArcPad map file (*.apm).
METADATA
The parent element for layer meta data.
SNAPPING
edge optional Restriction of xs:string
end optional Restriction of xs:string
tolerance optional xs:double
vertex optional Restriction of xs:string
visible optional Restriction of xs:string
SYMBOLOGY
The parent element for symbology in an ArcPad map file (*.apm) or layer definition.
