After developing an application with Ionic Framework, I incorporated canvas for image cropping. The functionality worked seamlessly on my browser.
However, when testing the app on a mobile device, I encountered issues:
Does anyone have insight into why this may be happening?
It's interesting how there are some amazing image crop modules in angular that actually work, despite the occasional issues with certain implementations. I recently incorporated one into a company app for document scanning, and it turned out to be quite useful. The module I chose allowed me to customize the shape, size, and other parameters of the crop area. You can check it out here: https://github.com/jodonnell-broadsoft/JsImageCrop This is a snippet of the code:
<div class="item item-image cropArea">
<img-Crop image="image.uncropped" result-image="image.cropped" result-image-format="image/png" area-type="rectangle" on-change="console.log($scope.image.cropped)">
</img-Crop>
</div>
