For native platforms, the return value is URI to a local image which is a result of transformation.
On the web is actually handier and easier to implement if a function would return
Feature Request
Add web support
Why it is needed
Make module cross-platform
Possible implementation
Hey, I made an investigation on how to implement
.cropImage
on the web.In general, a solution could use
canvas
with2d
context and usedrawImage
(https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D/drawImage) method to prepare cropped Image, then I could be returned to the user. And here my doubts started.For native platforms, the return value is URI to a local image which is a result of transformation.
On the web is actually handier and easier to implement if a function would return
ImageData

under the hoodbase64
encoded imageIn addition, some users may experience issues with CORS when resizing will be implemented using canvas https://blog.codepen.io/2013/10/08/cross-domain-images-tainted-canvas/
I would like to start a discussion on the topic of web support.
Personally I'm not sure if this feature is really needed.
