Configuration Object
| Property | Type | Description |
| -------------------- | :--------------------------: | :-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| cropType | string (default rectangular) | The cropType
property of the image cropping library specifies the type of cropping area used. It can be either 'rectangular' or 'circular'. This property determines the shape of the selectable crop area when using the library's crop functionality. |
| freeStyleCropEnabled | bool (default true) | When freeStyleCropEnabled
is set to true, users can freely adjust the cropping frame according to their preference, allowing for non-fixed cropping dimensions. |
| showCropFrame | bool (default true) | When showCropFrame
is set to true, the crop frame lines are displayed in the crop view, aiding users in adjusting the cropping area. |
| showCropGrid | bool (default true) | When showCropGrid
is set to true, a grid is displayed within the crop frame, providing a visual aid for precise cropping. |
| dimmedLayerColor | any (default #99000000
) | Specifies the color used to dim the background behind the crop image UI. You can use direct color names (e.g., "black") or specify colors using an ARGB hexadecimal format (e.g., #99000000 for semi-transparent black). |
| |
| imageQuality | integer (default 60
) | When imageQuality
is set to an integer between 60 (lower quality) and 100 (highest quality), it determines the quality of the image.
