+ * | desiredHeight | INTEGER |
+ * | synchronousLoading | BOOLEAN |
+ * | pixelArea | VECTOR4 |
+ * | wrapModeU | INTEGER OR STRING |
+ * | wrapModeV | INTEGER OR STRING |
+ *
+ * where pixelArea is a rectangular area.
+ * In its Vector4 value, the first two elements indicate the top-left position of the area,
+ * and the last two elements are the area width and height respectively.
+ * If not specified, the default value is [0.0, 0.0, 1.0, 1.0], i.e. the entire area of the image.
+ *
+ * where wrapModeU and wrapModeV separately decide how the texture should be sampled when the u and v coordinate exceeds the range of 0.0 to 1.0.
+ * Its value should be one of the following wrap mode:
+ * "DEFAULT"
+ * "CLAMP_TO_EDGE"
+ * "REPEAT"
+ * "MIRRORED_REPEAT"
*
* where imageFittingMode should be one of the following fitting modes:
* "SHRINK_TO_FIT"
* "DONT_CARE"
* "DEFAULT"
*
+ *
+ * If the Visual is in a LayerUI it will pixel align the image, using a Layer3D will disable pixel alignment.
+ * Changing layer behaviour between LayerUI to Layer3D whilst the visual is already staged will not have an effect.
