Fastest way to remove transparent edges from a SKImage

[JPDelprat]

Hello,

I want to crop some images by removing transparent edges.
What is the fastest way to do this ?

Currently, I create a SKImage from a byte[], with SKImage.FromEncodedData(request.ImageData);

"Simple" way to do it :

• create a SKBitmap first with SKBitmap.Decode(request.ImageData))
• modify the SKBitmap (unsafe access, examine all pixels) => create a new SKBitmap)
• convert the new bitmap to an image with SKImage.FromBitmap(bitmap);

Is there a fastest way to do this ?
If I have to modify my bitmap with pixel access, is there a fast algorithm ?
Is there a way to convert a bitmap to an image without copy (given that I won't use the bitmap after this).

Thank you
