javascript - 如何在木瓜查看器中使用平移工具

Question

嗨，我尝试为木瓜查看器实现 PAN 工具，但没有运气，我想出了这两个功能

papaya.viewer.Viewer.prototype.setCurrentPanLocation = function (xLoc, yLoc, sliceDirection) {

和 papaya.viewer.Viewer.prototype.setStartPanLocation = function (xLoc, yLoc, sliceDirection) {

任何人都可以帮助

Answer 1

经过详细研究后终于找到了这个答案

this.previousMousePosition.x = papaya.utilities.PlatformUtils.getMousePositionX(me);
this.previousMousePosition.y = papaya.utilities.PlatformUtils.getMousePositionY(me);
                    //  this.setStartPanLocationNew(Cord1.x, Cord1.y, this.mainImage.sliceDirection);
                    
this.setStartPanLocationNew(
                        this.convertScreenToImageCoordinateX(this.previousMousePosition.x, this.mainImage),
                        this.convertScreenToImageCoordinateY(this.previousMousePosition.y, this.mainImage),
                        this.mainImage.sliceDirection
                    );
