Detailed Description

This class represents a layer context for rendering. If user wants to render layers, please construct a layer context object first and then set it to a Renderer object by function Renderer.SetLayerContext.

Member Function Documentation

◆ constructor()

LayerContext.constructor	(	document	,
		usage_type
	)

Constructor, based on a PDF document and specified layer usage type.

Parameters

[in]	document	A valid PDF document object.
[in]	usage_type	Layer usage type. Please refer to values starting from LayerContext.e_UsageView and this should be one of these values except LayerContext.e_UsageZoom.

Examples: /Users/ec2-user/gitlab-runner/builds/E-xKdhDo/0/foxit/sdk/mobile/gsdk-doc-auto-build/harmony_nodejs/input/Index.js.

◆ CopyStates()

LayerContext.CopyStates ( source_context )

Copy states from another layer context.

Parameters

[in] source_context The source layer context, whose state will be copied to current layer context.

Returns: true means success, while false means failure.

Examples: /Users/ec2-user/gitlab-runner/builds/E-xKdhDo/0/foxit/sdk/mobile/gsdk-doc-auto-build/harmony_nodejs/input/Index.js.

◆ GetDocument()

LayerContext.GetDocument ( )

Get the related PDF document.

Returns: The related PDF document object.

Examples: /Users/ec2-user/gitlab-runner/builds/E-xKdhDo/0/foxit/sdk/mobile/gsdk-doc-auto-build/harmony_nodejs/input/Index.js.

◆ GetUsageType()

LayerContext.GetUsageType ( )

Get the layer usage type for rendering.

Returns: Layer usage type. Please refer to values starting from LayerContext.e_UsageView and this would be one of these values except LayerContext.e_UsageZoom.

Examples: /Users/ec2-user/gitlab-runner/builds/E-xKdhDo/0/foxit/sdk/mobile/gsdk-doc-auto-build/harmony_nodejs/input/Index.js.

◆ IsEmpty()

LayerContext.IsEmpty ( )

Check whether current object is empty or not.

When the current object is empty, that means current object is useless.

Returns: true means current object is empty, while false means not.

Examples: /Users/ec2-user/gitlab-runner/builds/E-xKdhDo/0/foxit/sdk/mobile/gsdk-doc-auto-build/harmony_nodejs/input/Index.js.

◆ IsVisible()

LayerContext.IsVisible ( layer )

Check if a specified layer node is visible in current layer context.

Parameters

[in] layer A layer node. It should belong to the same PDF document which is related to current layer context.

Returns: true means the layer node is visible, while false means the layer node is invisible.

Examples: /Users/ec2-user/gitlab-runner/builds/E-xKdhDo/0/foxit/sdk/mobile/gsdk-doc-auto-build/harmony_nodejs/input/Index.js.

◆ MergeStates()

LayerContext.MergeStates ( source_context )

Merge states from another layer context.

Parameters

[in] source_context The source layer context, whose state will be merged to current layer context.

Returns: true means success, while false means failure.

Examples: /Users/ec2-user/gitlab-runner/builds/E-xKdhDo/0/foxit/sdk/mobile/gsdk-doc-auto-build/harmony_nodejs/input/Index.js.

◆ Reset()

LayerContext.Reset ( )

Reset current layer context, back to the initialized state.

Returns: true means success, while false means failure.

Examples: /Users/ec2-user/gitlab-runner/builds/E-xKdhDo/0/foxit/sdk/mobile/gsdk-doc-auto-build/harmony_nodejs/input/Index.js.

◆ SetVisible()

LayerContext.SetVisible	(	layer	,
		is_visible
	)

Set the visibility of a specified layer node in current layer context.

Parameters

[in]	layer	A layer node. It should belong to the same PDF document which is related to current layer context.
[in]	is_visible	true means visible, and false means invisible.

Returns: true means the layer node is visible, while false means the layer node is invisible.

Examples: /Users/ec2-user/gitlab-runner/builds/E-xKdhDo/0/foxit/sdk/mobile/gsdk-doc-auto-build/harmony_nodejs/input/Index.js.
