Example 26 with ComposeShader

use of android.graphics.ComposeShader in project AndroidPicker by gzu-liyujiang.

the class ColorGradientView method buildShader.

private void buildShader() {
    if (brightnessGradient) {
        mShader = new LinearGradient(mGradientRect.left, mGradientRect.top, mGradientRect.right, mGradientRect.top, mSelectedColorGradient, null, Shader.TileMode.CLAMP);
    } else {
        LinearGradient gradientShader = new LinearGradient(mGradientRect.left, mGradientRect.top, mGradientRect.right, mGradientRect.top, GRAD_COLORS, null, Shader.TileMode.CLAMP);
        LinearGradient alphaShader = new LinearGradient(0, mGradientRect.top + (mGradientRect.height() / 3), 0, mGradientRect.bottom, GRAD_ALPHA, null, Shader.TileMode.CLAMP);
        mShader = new ComposeShader(alphaShader, gradientShader, PorterDuff.Mode.MULTIPLY);
    }
    mPaint.setShader(mShader);
}

Example 27 with ComposeShader

use of android.graphics.ComposeShader in project little-bear-dictionary by daimajia.

the class ColorPickerView method drawSatValPanel.

private void drawSatValPanel(Canvas canvas) {
    final RectF rect = mSatValRect;
    if (BORDER_WIDTH_PX > 0) {
        mBorderPaint.setColor(mBorderColor);
        canvas.drawRect(mDrawingRect.left, mDrawingRect.top, rect.right + BORDER_WIDTH_PX, rect.bottom + BORDER_WIDTH_PX, mBorderPaint);
    }
    if (mValShader == null) {
        mValShader = new LinearGradient(rect.left, rect.top, rect.left, rect.bottom, 0xffffffff, 0xff000000, TileMode.CLAMP);
    }
    int rgb = Color.HSVToColor(new float[] { mHue, 1f, 1f });
    mSatShader = new LinearGradient(rect.left, rect.top, rect.right, rect.top, 0xffffffff, rgb, TileMode.CLAMP);
    ComposeShader mShader = new ComposeShader(mValShader, mSatShader, PorterDuff.Mode.MULTIPLY);
    mSatValPaint.setShader(mShader);
    canvas.drawRect(rect, mSatValPaint);
    Point p = satValToPoint(mSat, mVal);
    mSatValTrackerPaint.setColor(0xff000000);
    canvas.drawCircle(p.x, p.y, PALETTE_CIRCLE_TRACKER_RADIUS - 1f * mDensity, mSatValTrackerPaint);
