# Class Graphics

public final class Graphics extends Object

Abstracts the underlying platform graphics context thus allowing us to achieve portability between MIDP devices and CDC devices. This abstaction simplifies and unifies the Graphics implementations of various platforms.

A graphics instance should never be created by the developer and is always accessed using either a paint callback or a mutable image. There is no supported way to create this object directly.

On every port today `isTranslationSupported() == false`, which means `g.translate(int, int)` is added to draw coordinates before the impl matrix is applied; a subsequent `g.scale()` or `g.rotate()` therefore multiplies the integer translate too. That's surprising when porting code that came from Java2D / AWT where translate composes into the matrix the same way as scale and rotate.

        });

        hi.show();

    ###### Parameters

    - `shape`: The shape to clip.

    ###### See also

    - #isShapeClipSupported

  - ### getClipY

    public int getClipY()

    Returns the y clipping position

    ###### Returns

    the y clipping position

  - ### getClipWidth

    public int getClipWidth()

    Returns the clip width

    ###### Returns

    the clip width

  - ### getClipHeight

    public int getClipHeight()

    Returns the clip height

    ###### Returns

    the clip height

  - ### isVisible

    public boolean isVisible(int x, int y, int w, int h)

    Returns true if the given rectangle (in the current Graphics coordinate space, with the active translation applied) intersects the current clip rectangle, i.e. anything drawn into it would be at least partially visible.

    Use this to skip work for off-screen draws - typical case is a zoomed canvas where most images fall outside the visible window and should not be decoded or scaled.

        if (g.isVisible(x, y, w, h)) {
            g.drawImage(image, x, y, w, h);
        }

    When a non-identity affine transform is in effect (see `setTransform(Transform)`), the four corners of the rectangle are mapped through the current transform and the axis-aligned bounding box of the result is tested against the clip. This means a rotated/scaled rectangle is judged by where it actually lands on screen rather than by its untransformed coordinates. The integer translate (`translate(int, int)`) is intentionally not added here: `getClipX()`/`getClipY()` are already reported in the same untranslated coordinate space you pass to draw calls, so the translation cancels out.

    Note: shape-clipped graphics (`setClip(Shape)`) fall back to the bounding rectangle of the clip, and perspective (3D) transforms are approximated by their 2D corner projection; this matches the precision actually used by the platform draw calls.

    ###### Parameters

    - `x`: left edge of the rectangle

    - `y`: top edge of the rectangle

    - `w`: width of the rectangle

    - `h`: height of the rectangle

    ###### Returns

    true if the rectangle intersects the current clip

  - ### clipRect

    public void clipRect(int x, int y, int width, int height)

    - `y`: the y coordinate of the rectangle to intersect the clip with

    - `width`: the width of the rectangle to intersect the clip with

    - `height`: the height of the rectangle to intersect the clip with

  - ### setClip

    public void setClip(int x, int y, int width, int height)

    Updates the clipping region to match the given region exactly

    ###### Parameters

    public void drawShadow(Image img, int x, int y, int offsetX, int offsetY, int blurRadius, int spreadRadius, int color, float opacity)

    ###### Deprecated

    this method should have been internals

  - ### clearRect

    public void clearRect(int x, int y, int width, int height)

    Clears rectangular area of the graphics context. This will remove any color information that has already been drawn to the graphics context making it transparent.

    The difference between this method and say `int, int, int)` with alpha=0 is that fillRect() will just blend with the colors underneath (and thus `int, int, int)` with an alpha of 0 actually does nothing.

    Note: You can specify a custom `Paint` to use for filling the shape using the `#setColor(com.codename1.ui.Paint)` method. This is useful for filling the shape with a `LinearGradientPaint`, for example.

    ###### Parameters

    - `shape`: The shape to be filled.

    ###### See also

    - #isShapeSupported

  - ### fillShapeShadow

    public void fillShapeShadow(Shape shape, int fillColor, int fillAlpha, int shadowColor, float shadowOpacity, int blurRadius, int offsetX, int offsetY)

    Fills the given shape and casts a blurred drop shadow behind it in a single GPU-accelerated draw where the platform supports it (e.g. Android `Paint.setShadowLayer`, iOS `CGContextSetShadow`), with no retained bitmap. This lets borders/decorations render soft shadows every frame without caching a per-component image. Guard with `#isShapeShadowSupported()` and fall back to your own path otherwise.

    ###### Parameters

    - `shape`: the shape to fill (and whose fill casts the shadow)

    - `fillColor`: the fill color as 0xRRGGBB

    - `fillAlpha`: the fill alpha 0..255

    - `shadowColor`: the shadow color as 0xRRGGBB

    - `shadowOpacity`: the shadow opacity in the range 0..1

    - `blurRadius`: the gaussian blur radius in pixels

    - `offsetX`: the shadow x offset in pixels

    - `offsetY`: the shadow y offset in pixels

  - ### isShapeShadowSupported

    public boolean isShapeShadowSupported()

    Checks whether `#fillShapeShadow` renders a GPU shadow on this platform. When false the caller should draw its shadow another way (e.g. the cached-image fallback in `RoundRectBorder`).

    ###### Returns

    true if a GPU shape shadow is supported by the current graphics context

  - ### isTransformSupported

    public boolean isTransformSupported()

    Checks to see if `com.codename1.ui.geom.Matrix` transforms are supported by this graphics context.

    ###### Returns

    Returns:

      true if this graphics context supports `com.codename1.ui.geom.Matrix` transforms.

      Note that this method only confirms that 2D transforms are supported. If you need to perform 3D transformations, you should use the `#isPerspectiveTransformSupported` method.

      ###### See also

      - #setTransform

      - #getTransform

      - #isPerspectiveTransformSupported

  - public boolean isPerspectiveTransformSupported()

    Checks to see if perspective (3D) `com.codename1.ui.geom.Matrix` transforms are supported by this graphics context. If 3D transforms are supported, you can use a 4x4 transformation `com.codename1.ui.geom.Matrix` via `#setTransform` to perform 3D transforms.

    Note: It is possible for 3D transforms to not be supported but Affine (2D) transforms to be supported. In this case you would be limited to a 3x3 transformation matrix in `#setTransform`. You can check for 2D transformation support using the `#isTransformSupported` method.

    ###### Returns

    true if Perspective (3D) transforms are supported. false otherwise.

    ###### See also

    - #isTransformSupported

    - #setTransform

    - #getTransform

  - ### isShapeSupported

    public boolean isShapeSupported()

    Checks to see if this graphics context supports drawing shapes (i.e. `#drawShape` and `#fillShape` methods. If this returns false, and you call `#drawShape` or `#fillShape`, then nothing will be drawn.

    ###### Returns

    true If `#drawShape` and `#fillShape` are supported.

    ###### See also

    - #drawShape

    - #fillShape

  - ### isShapeClipSupported

    public boolean isShapeClipSupported()

    Checks to see if this graphics context supports clip Shape. If this returns false, calling setClip(Shape) will have no effect on the Graphics clipping area

    ###### Returns

    true If setClip(Shape) is supported.

  - ### transform

    public void transform(Transform transform)

    Concatenates the given transform to the context's transform.

    ###### Parameters

    - `transform`: The transform to concatenate.

  - ### getTransform

    public Transform getTransform()

    Gets the transformation matrix that is currently applied to this graphics context.

    Unlike `java.awt.Graphics2D.getTransform()`, the matrix returned here does not include the integer translation set via `#translate(int, int)`. Codename One keeps that translation as a separate accumulator (`#getTranslateX()` / `#getTranslateY()`) that is applied independently of the affine matrix, so a freshly-translated context still reports the identity transform. This split is deliberate: `#setTransform` / `getTransform` / `#transform(com.codename1.ui.Transform)` round-trip correctly only because the translate is excluded here -- folding it in would cause it to be counted twice (once in the matrix, once in the drawing pipeline).

    Consequently, to map a point from the current drawing coordinate space to the context's device coordinates you must add the translation yourself:

        float[] pt = { x + g.getTranslateX(), y + g.getTranslateY() };
        g.getTransform().transformPoint(pt, pt);
        // pt now holds the transformed device coordinates

    If you only need to know whether a rectangle would be drawn on screen, prefer `#isVisible(int, int, int, int)`, which performs this mapping (translate + transform) internally and tests it against the clip.

    ###### Returns

    The current transformation matrix, excluding the integer translate.

    ###### Deprecated

    Use `#getTransform(com.codename1.ui.Transform)` instead.

    ###### See also

    - #setTransform

    - #getTranslateX

    - #isVisible(int, int, int, int)

  - ### setTransform

    public void setTransform(Transform transform)

    Sets the transformation `com.codename1.ui.geom.Matrix` to apply to drawing in this graphics context. In order to use this for 2D/Affine transformations you should first check to make sure that transforms are supported by calling the `#isTransformSupported` method. For 3D/Perspective transformations, you should first check to make sure that 3D/Perspective transformations are supported by calling the `#isPerspectiveTransformSupported`.

    Transformations are applied with (0,0) as the origin. So rotations and scales are anchored at this point on the screen. You can use a different anchor point by either embedding it in the transformation matrix (i.e. pre-transform the `com.codename1.ui.geom.Matrix` to anchor at a different point) or use the `int, int)` variation that allows you to explicitly set the anchor point.

    ###### Parameters

    - `transform`: @param transform The transformation `com.codename1.ui.geom.Matrix` to use for drawing. 2D/Affine transformations can be achieved using a 3x3 transformation `com.codename1.ui.geom.Matrix`. 3D/Perspective transformations can be achieved using a 4x3 transformation `com.codename1.ui.geom.Matrix`.

    - #setTransform(com.codename1.ui.geom.Matrix, int, int)

  - ### getTransform

    public void getTransform(Transform t)

    Loads the provided transform with the current transform applied to this graphics context.

    As with `#getTransform()`, the loaded matrix does not include the integer translation set via `#translate(int, int)`; add `#getTranslateX()` / `#getTranslateY()` to a point before transforming it if you need device coordinates.

    ###### Parameters

    - `t`: An "out" parameter to be filled with the current transform.

  - ### fillTriangle

The Gradient may be a `LinearGradient`, `RadialGradient`, or `ConicGradient` - the port picks the right native shader path (Java2D `LinearGradientPaint`/`RadialGradientPaint` on JavaSE; Android `LinearGradient`/`RadialGradient`/`SweepGradient` shaders; software rasterizer fallback elsewhere). Pass null or width/height <= 0 for a no-op.

  - ### setAntiAliasedText

    public void setAntiAliasedText(boolean a)

    Set whether antialiasing for text is active, notice that text antialiasing is a separate attribute from standard anti-alisaing.

    ###### Parameters

    - `a`: true if text antialiasing is supported

  - ### isAffineSupported

    public boolean isAffineSupported()

    Indicates whether the underlying implementation can draw using an affine transform hence methods such as rotate, scale and shear would work

    ###### Returns

    true if an affine transformation matrix is present

  - ### resetAffine

    public void resetAffine()
    Resets the affine transform to the default value

  - ### scale

    public void scale(float x, float y)

    Scales the coordinate system using the affine transform

    ###### Parameters

    - `x`: scale factor for x

    - `y`: scale factor for y

  - ### translateMatrix

    public void translateMatrix(float x, float y)

    Translates the coordinate system using the affine transform matrix (as opposed to `#translate(int, int)` which uses a per-Graphics integer accumulator). On every port today `isTranslationSupported() == false`, which means `g.translate(int, int)` is added to draw coordinates before the impl matrix is applied; a subsequent `g.scale()` or `g.rotate()` therefore multiplies the integer translate too. That's surprising when porting code that came from Java2D / AWT where translate composes into the matrix the same way as scale and rotate.

    `translateMatrix` composes the translation directly onto the impl matrix, exactly like `#scale(float, float)` and `#rotate(float)` do. The result is uniform "post-multiply translate onto the current transform" semantics across iOS / JavaSE / Android / JavaScript -- the same code produces the same on-screen position regardless of which port you target or whether you're drawing into a Form's Graphics or a mutable Image's Graphics.

    On ports where `#isTranslateMatrixSupported()` returns false (e.g. the legacy JavaScript port) the call falls back to the integer `#translate(int, int)` so apps don't silently render at the wrong position -- the visual result on those ports matches whatever `translate(int, int)` does there.

    ###### Parameters

    - `x`: x-axis translation

    - `y`: y-axis translation

    - `#isTranslateMatrixSupported()`
    - `#translate(int, int)`
    - `#scale(float, float)`
    - `#rotateRadians(float, int, int)`

  - ### isTranslateMatrixSupported

    public boolean isTranslateMatrixSupported()

    Checks whether `#translateMatrix(float, float)` composes through the impl matrix on this port (the matrix-correct mode) versus falling back to the integer `#translate(int, int)` accumulator. Use this to gate code that needs matrix-correct translation semantics.

    ###### Returns

    true if `translateMatrix` reaches the impl matrix; false on ports where it falls back to the integer accumulator.
