AI Technical Summary
Technical Problem
In existing technologies, when users extract and transmit images by long-pressing and dragging, the operation is complicated and the extracted image may be incomplete, resulting in a fragmented transmitted image.
Method used
Before the user drags and drops, the electronic device uses a low-resolution bitmap to extract a low-resolution cutout image and saves it. After dragging and dropping, it uses a high-resolution bitmap to extract a high-resolution cutout image and saves it, ensuring the integrity of the transmitted image.
Benefits of technology
While maintaining ease of operation, it ensures that the transmitted cutout images are complete and high-definition, avoiding incomplete images caused by the image not being fully saved before the dragging action ends.

Abstract
This application provides an image processing method and related apparatus. Implementing this method, after a user triggers the image cutout process, the electronic device first uses a low-resolution bitmap corresponding to the image to cut out a low-resolution cutout image. Because the low-resolution cutout image has low memory usage, the electronic device can completely save the low-resolution cutout image as a transmittable, low-resolution image file before the user ends the dragging action. After the user drags, the electronic device can then use a high-resolution bitmap to cut out a high-resolution cutout image and save it as a shareable, high-resolution image file. This high-resolution image file can overwrite the aforementioned low-resolution image file. Thus, even if the user ends the dragging action before the high-resolution image file is successfully saved, the electronic device can still transmit the low-resolution image; conversely, if the user ends the dragging action after the high-resolution image file is successfully saved, the electronic device can transmit the high-resolution image.
