Force the image width & height #958

Closed baj84 closed 6 years ago

baj84 commented 6 years ago

I am using the cropper to crop big images 6000 pixels+, instead of loading in such a large image i'm trying to use a smaller image (500x500px) and just stretch it (lose of quality isn't an issue), so that the cropping is still relative to the large image.

Is this possible?

Cheers

Just compute by the scale ratio:

const scaledRatio = 6000 / 500;

// cropping...

const croppedData = cropper.getData();

croppedData.x *= scaledRatio;
croppedData.y *= scaledRatio;
croppedData.width *= scaledRatio;
croppedData.height *= scaledRatio;

// upload the cropped data...
