Examples with PointF android.graphics.PointF used on opensource projects

Example 1 with PointF

use of android.graphics.PointF in project Signal-Android by WhisperSystems.

the class ScribbleActivity method addTextSticker.

protected void addTextSticker() {
    TextLayer textLayer = createTextLayer();
    TextEntity textEntity = new TextEntity(textLayer, scribbleView.getWidth(), scribbleView.getHeight());
    scribbleView.addEntityAndPosition(textEntity);
    // move text sticker up so that its not hidden under keyboard
    PointF center = textEntity.absoluteCenter();
    center.y = center.y * 0.5F;
    textEntity.moveCenterTo(center);
    // redraw
    scribbleView.invalidate();
    startTextEntityEditing();
    changeTextEntityColor(toolbar.getToolColor());
}

Example 2 with PointF

use of android.graphics.PointF in project Signal-Android by WhisperSystems.

the class MoveGestureDetector method updateStateByEvent.

protected void updateStateByEvent(MotionEvent curr) {
    super.updateStateByEvent(curr);
    final MotionEvent prev = mPrevEvent;
    // Focus intenal
    mCurrFocusInternal = determineFocalPoint(curr);
    mPrevFocusInternal = determineFocalPoint(prev);
    // Focus external
    // - Prevent skipping of focus delta when a finger is added or removed
    boolean mSkipNextMoveEvent = prev.getPointerCount() != curr.getPointerCount();
    mFocusDeltaExternal = mSkipNextMoveEvent ? FOCUS_DELTA_ZERO : new PointF(mCurrFocusInternal.x - mPrevFocusInternal.x, mCurrFocusInternal.y - mPrevFocusInternal.y);
    // - Don't directly use mFocusInternal (or skipping will occur). Add
    // 	 unskipped delta values to mFocusExternal instead.
    mFocusExternal.x += mFocusDeltaExternal.x;
    mFocusExternal.y += mFocusDeltaExternal.y;
}

Example 3 with PointF

use of android.graphics.PointF in project Signal-Android by WhisperSystems.

the class MotionView method findEntityAtPoint.

@Nullable
private MotionEntity findEntityAtPoint(float x, float y) {
    MotionEntity selected = null;
    PointF p = new PointF(x, y);
    for (int i = entities.size() - 1; i >= 0; i--) {
        if (entities.get(i).pointInLayerRect(p)) {
            selected = entities.get(i);
            break;
        }
    }
    return selected;
}

Example 4 with PointF

use of android.graphics.PointF in project Signal-Android by WhisperSystems.

the class TextEntity method updateEntity.

private void updateEntity(boolean moveToPreviousCenter) {
    // save previous center
    PointF oldCenter = absoluteCenter();
    Bitmap newBmp = createBitmap(getLayer(), bitmap);
    // recycle previous bitmap (if not reused) as soon as possible
    if (bitmap != null && bitmap != newBmp && !bitmap.isRecycled()) {
        bitmap.recycle();
    }
    this.bitmap = newBmp;
    float width = bitmap.getWidth();
    float height = bitmap.getHeight();
    @SuppressWarnings("UnnecessaryLocalVariable") float widthAspect = 1.0F * canvasWidth / width;
    // for text we always match text width with parent width
    this.holyScale = widthAspect;
    // initial position of the entity
    srcPoints[0] = 0;
    srcPoints[1] = 0;
    srcPoints[2] = width;
    srcPoints[3] = 0;
    srcPoints[4] = width;
    srcPoints[5] = height;
    srcPoints[6] = 0;
    srcPoints[7] = height;
    srcPoints[8] = 0;
    srcPoints[8] = 0;
    if (moveToPreviousCenter) {
        // move to previous center
        moveCenterTo(oldCenter);
    }
}
