Regardless of layer type (vector, raster, or image), the Display group in Layer Properties panel provides common parameters including:

Visible

Controls layer visibility. When checked, the layer is visible; otherwise hidden.

When unchecked, Selectable, Editable, and Snappable become unavailable.

Layer Visible can also be controlled through:

• Visible icon before layers in Layer Manager
• Context menu of selected layer in Layer Manager → Visible
• Layer Manager → Layer Control → Visible

Selectable

Controls whether features in this layer can be selected. When checked, features are selectable; otherwise not.

Layer Selectable can also be controlled through:

• Selectable icon before layers in Layer Manager
• Context menu of selected layer in Layer Manager → Selectable
• Layer Manager → Layer Control → Selectable

Editable

Controls whether features in vector layers can be edited. When checked, features are editable; otherwise not.

Layer Editable can also be controlled through:

• Editable icon before layers in Layer Manager
• Context menu of selected layer in Layer Manager → Editable
• Layer Manager → Layer Control → Editable

Snappable

Controls whether features in vector layers can be snapped. When checked, features can be snapped during selection or editing; otherwise not.

Layer Snappable can also be controlled through:

• Snappable icon before layers in Layer Manager
• Context menu of selected layer in Layer Manager → Snappable
• Layer Manager → Layer Control → Snappable

Layer Name

Displays uneditable layer name serving as unique identifier in the map.

Layer Caption

Displays layer alias in Layer Manager. Editable modifications update immediately in Layer Manager.

Transparency:

Sets layer transparency.

Input value directly or use spin buttons. Default: 0 (opaque). Valid range: [0,100] integers. 0=opaque, 100=fully transparent.

Blend Mode

Sets overlay calculation method between layers for different rendering effects.

Available modes:

Mode Category	Mode Name	Description
Normal Mode	Normal	No color alteration. Default blending type.
Darken	Darken	Uses minimum RGB values from both layers for final color.
	Multiply	Multiplies layer colors, typically darkening result.
	Color Burn	Darkens base layer colors, white remains unchanged.
	Linear Burn	Adds layer colors then subtracts 1.
Lighten	Lighten	Uses maximum RGB values from both layers.
	Screen	Inverts and multiplies colors, brightening result.
	Color Dodge	Reduces contrast and increases brightness. Black unchanged.
	Linear Dodge	Adds brightness values. Black unchanged.
Contrast	Overlay	Multiplies dark areas (<0.5), screens light areas.
	Soft Light	Similar to Overlay with reduced contrast.
	Hard Light	Multiplies dark areas, screens light areas from current layer.
	Vivid Light	Combines Color Burn and Color Dodge.
	Linear Light	Brightens areas >0.5, darkens areas <0.5.
	Pin Light	Replaces darker pixels if layer >50% gray; replaces lighter pixels if layer <50% gray.
Difference	Difference	Subtracts layer colors then adds base color divided by 2.
	Subtract	Subtracts upper layer color from lower layer.

Fill Mode

Controls fill symbol rendering with Global Mode or Object Mode.

• Global Mode: Renders from layer's top-left corner, filling entire layer.
• Object Mode: Renders from individual feature's top-left corner, filling each feature separately.

Weight

Sets display order priority for label/text layers. Higher values get higher display priority. Used for multi-layer display control.

Requires enabling Label Always Top in Map Properties.

Minimum Visible Scale

Input scale value (e.g. 1:500000) or select from dropdown to set minimum scale. Layer becomes invisible when map scale is smaller than set value.

Maximum Visible Scale

Input scale value (e.g. 1:100000) or select from dropdown to set maximum scale. Layer becomes invisible when map scale is larger than set value.
