    An ImageSource that displays a single, static image.

    The image must be either a PNG, JPG or WebP file, whose dimensions are not greater than the maximal texture size allowed by WebGL on this browser.

    containsFn: CustomContainsFn | undefined
    datatype: TextureDataType

    Gets the datatype of images generated by this source.

    flipY: boolean

    Gets whether images generated from this source should be flipped vertically.

    isImageSource: boolean = ...
    isMemoryUsage: true = ...

    Readonly flag to indicate that his object implements MemoryUsage.

    isStaticImageSource: true = ...
    priority: RequestPriority = 'auto'
    synchronous: boolean = false

    If true, this source can immediately generate images without any delay.

    transparent: boolean
    type: "StaticImageSource" = ...

    Accessors

    • get colorSpace(): ColorSpace

      Gets the color space of the textures generated by this source.

      Returns ColorSpace

    Methods

    • Returns an adjusted extent, width and height so that request pixels are aligned with source pixels, and requests do not oversample the source.

      Parameters

      • requestExtent: Extent

        The request extent.

      • requestWidth: number

        The width, in pixels, of the request extent.

      • requestHeight: number

        The height, in pixels, of the request extent.

      Returns GridExtent | null

      The adjusted parameters.

    • Gets whether this source contains the specified extent. If a custom contains function is provided, it will be used. Otherwise, intersects is used.

      This method is mainly used to discard non-relevant requests (i.e don't process regions that are not relevant to this source).

      Parameters

      • extent: Extent

        The extent to test.

      Returns boolean

    • Test the intersection between the specified extent and this source's extent. This method may be overriden to perform special logic.

      Parameters

      • extent: Extent

        The extent to test.

      Returns boolean

      true if the extent and this source extent intersects, false otherwise.
