||
| ### Get EditableImage | ||
|
|
||
| ```cs | ||
| var image = await CrossImageEdit.Current.CreateImageAsync(imageByteArray); | ||
| ``` | ||
| It is able to manipulate a image using this object. | ||
|

| ``` | ||
|
|
||
| ### Rotate | ||
|
|
||
| ```cs | ||
| var degree = 90; // 0-360; | ||
| image.Rotate(degree); | ||
| ``` | ||
|
|
||
| ### ToPng | ||
|
|
||
| ```cs | ||
| var pngBytes = image.ToPng(); | ||
| ``` | ||
|
|
||
| ### ToJpeg | ||
|
|
||
| ```cs | ||
| var jpgBytes = image.ToJpeg(90); // quality(0-100) | ||
| ``` | ||
|
|
||
| ### ToArgbPixels | ||
|
|
||
| Get image ARGB infomation. | ||
|
|
||
| for example when 0xFF00F090 | ||
|
|
||
| |A|R|G|B| | ||
| | -- | :---: | :--: | :--: | | ||
| |FF|00|F0 |90| | ||
|
|
||
|
|

| var pixels = image.ToArgbPixels(); | ||
| ``` | ||
