Picture exporting method and device, electronic equipment and readable storage medium

Abstract

The embodiment of the invention provides a picture exporting method and a device, electronic equipment and a readable storage medium. The method comprises the steps of determining a to-be-exported target picture in a portable document format PDF document; decompressing the target picture to obtain a decompressed picture; segmenting the decompressed picture into a plurality of picture blocks; obtaining a pixel point set corresponding to each picture block according to a preset obtaining rule; wherein the preset acquisition rule comprises: acquiring a pixel point set corresponding to one pictureblock or a target number of picture blocks each time; wherein the target number is smaller than the number of the picture blocks; and generating an exported picture corresponding to the target picture according to the obtained pixel point set corresponding to each picture block. In this way, the electronic equipment only needs to process one picture block or the picture blocks of the target number each time, and the decompressed picture does not need to be processed at a time. The situation that when a large picture is exported, picture exporting fails due to the fact that the memory of the electronic equipment is insufficient is avoided.
