Core structure
﻿
instanceId
The unique identifier for the avatar-field.
label
Provide a label/name for the avatar. 'Label' is displayed as a placeholder when no value is specified. Note the label is displayed at the top of the popup screen where you select images.
Other options
﻿
color
Sets the color of the avatar-field based on conditions by using the when property. First evaluated to true will be used. Choose a color from the provided color palette. Default color is grey if the property is not specified in the YAML. See the list of available colors in Jigx color palette﻿.
errorText
Add text, string, or expressions to show text under the avatar-field indicating an error/invalid value in the field. Text is shown in isNegative (red) styling.
helperText
Add text, string, or expressions to guide users by showing text under the avatar-field. Helper text is displayed only when there is no errorText. 
imageQuality
Image quality after compression (from 0 to 100, where 100 is the best quality). On iOS, values larger than 80 don't produce a noticeable quality increase in most images, while a value of 80 will reduce the file size by about half or less compared to a value of 100. Default: 100 (Android)/ 80 (iOS).
icon
Add an icon to the title. A list of icons is available. See Jigx icons﻿ for more information.
imageCropping
You can set the following with imageCropping :
isEnabled - allows you to crop an image if set to true. 
isFreeStyleCropEnabled - when set to true it supports custom cropping to change the size or aspect ratio of an image.
height - maximum allowed is 5000px
width- maximum allowed is 5000px
initialValue
Initial value of the relevant field. You can use this to preset value, so user doesn't need to add anything and use this "default". Using the reset-state action with initialValues does not clear the field, it resets the field back to it's initialValue. 
isAutoFocused
If true it will get focus immediately after it is displayed.
isHidden
If true the avatar-field will be hidden on the form. If set to false the field will be shown.
isIgnored
When true, the field will be ignored when submitting the form and the content will not be stored.
isOptionalLabelHidden
If the field is optional you can turn off the "(optional)" label by setting this field to true. Note the (optional) text in the label is displayed at the top of the popup screen where you select images. This property works in combination with isRequired: false.
isRequired
Set to true when the field is required. Useful when you use it in form submission. When set to false the (optional) text in the label is displayed at the top of the popup screen where you select images.
maximumFileSize
Maximum file size in bytes. Set to 'none' to disable size check. Default value is =6 * 1024 * 1024 6MB. 
nextProperty
Name of the property you want to focus next in the form when you use return/next on a keyboard.
style
The following property settings are available:
- flex - Flex property if rendered inside row.
- isBusy - Displays a spinner. 
- isDisabled - disables the avatar-field preventing the image selection popup from displaying.
- isPositive
More than one can be true. It will be evaluated based on priority.
value
The value to show for the field. Text field is a controlled component, which means the internal value will be forced to match this value prop if provided. In most cases, you don't need to use this.
Actions

The action is triggered when the content in the avatar-field is changed. Use IntelliSense (ctrl+space) to see the list of available actions.
