DicomRenderer class

GPU-accelerated DICOM image renderer.

This tool handles the complete rendering pipeline:

1. Compiles the GLSL fragment shader on first use.
2. Packs 16-bit pixel data into an 8-bit RGBA texture.
3. Applies windowing, Hounsfield transform, colorization, and inversion on the GPU.

Use render for a one-call render-to-ui.Image, or use createTexture and renderToImage separately when you need to reuse the texture across many windowing settings.

Constructors

DicomRenderer({DicomColorMap colorMap = DicomColorMap.grayscale, bool invert = false})

Creates a renderer.

Properties

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

shader → Future<FragmentShader?>

Ensures the fragment shader has been compiled.

Methods

createTexture(DicomParseResult result, {double? windowCenter, double? windowWidth, bool applyWindowing = false}) → Future<Image>

Packs 16-bit DICOM pixel data into an 8-bit RGBA ui.Image texture.

dispose() → void

Releases the compiled shader. Call when the renderer is no longer needed.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

render(DicomParseResult result, {double? windowCenter, double? windowWidth, DicomColorMap? colorMap, bool? invert, int rotationSteps = 0}) → Future<Image>

Renders a DICOM frame to a ui.Image in a single call.

renderToImage(DicomParseResult result, Image texture, {double? windowCenter, double? windowWidth, DicomColorMap? colorMap, bool? invert, int rotationSteps = 0}) → Future<Image>

Renders an already-created texture to a new ui.Image.

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
