applies_color_filter()

constexpr bool flutter::DisplayListAttributeFlags::applies_color_filter ( ) const

inlineconstexpr

The primitive honors the current DlColorFilter, including the related attribute InvertColors

Definition at line 196 of file dl_op_flags.h.

                                              {
    return has_any(kUsesColorFilter);
  }

applies_image_filter()

constexpr bool flutter::DisplayListAttributeFlags::applies_image_filter ( ) const

inlineconstexpr

Definition at line 209 of file dl_op_flags.h.

                                              {
    return has_any(kUsesImageFilter);
  }

applies_mask_filter()

constexpr bool flutter::DisplayListAttributeFlags::applies_mask_filter ( ) const

inlineconstexpr

The primitive honors the DlMaskFilter whether set using the filter object or using the convenience method |setMaskBlurFilter|

Definition at line 206 of file dl_op_flags.h.

                                             {
    return has_any(kUsesMaskFilter);
  }

applies_path_effect()

constexpr bool flutter::DisplayListAttributeFlags::applies_path_effect ( ) const

inlineconstexpr

Definition at line 201 of file dl_op_flags.h.

                                             {
    return has_any(kUsesPathEffect);
  }

applies_shader()

constexpr bool flutter::DisplayListAttributeFlags::applies_shader ( ) const

inlineconstexpr

The primitive can use any of the stroke attributes, such as StrokeWidth, StrokeMiter, StrokeCap, or StrokeJoin. This method will return if the primitive is defined as one that strokes its geometry (such as |drawLine|) or if it is defined as one that honors the Style attribute. If the Style attribute is known then a more accurate answer can be returned from the |is_stroked| method by supplying the actual setting of the style.

Definition at line 193 of file dl_op_flags.h.

{ return has_any(kUsesShader); }

applies_style()

constexpr bool flutter::DisplayListAttributeFlags::applies_style ( ) const

inlineconstexpr

The primitive dynamically determines whether it is a stroke or fill operation (or both) based on the setting of the |Style| attribute.

Definition at line 182 of file dl_op_flags.h.

constexpr bool flutter::DisplayListAttributeFlags::is_stroked ( DlDrawStyle  style = DlDrawStyle::kStroke ) const

inlineconstexpr

Definition at line 215 of file dl_op_flags.h.

    return (has_any(kIsStrokedGeometry) ||
            (style != DlDrawStyle::kFill && has_any(kIsDrawnGeometry)));

          // miter joins that weren't already present in the original path
          // and it does not grow the bounds of the path, but it can add
          // end caps to areas that might not have had them before so all
          // we need to do is to indicate the potential for diagonal
          // end caps and move on.
