Jquery mobile 用于jQuery Mobile的平移和缩放图像
如果您能为jquery移动web应用提供平移和缩放方面的帮助，我将不胜感激。我有一个建筑平面图的图像，上面有一个图像地图，我希望用户能够通过手机查看，放大和缩小感兴趣的区域并将其平移到视图中。这应该可以做到 这应该能奏效 我解决了OpenLayers的问题，现在图像可以平移和缩放Jquery mobile 用于jQuery Mobile的平移和缩放图像,jquery-mobile,zooming,pan,Jquery Mobile,Zooming,Pan,如果您能为jquery移动web应用提供平移和缩放方面的帮助，我将不胜感激。我有一个建筑平面图的图像，上面有一个图像地图，我希望用户能够通过手机查看，放大和缩小感兴趣的区域并将其平移到视图中。这应该可以做到 这应该能奏效 我解决了OpenLayers的问题，现在图像可以平移和缩放 现在必须弄清楚如何将它与imagemapster结合起来。。(http://www.outsharked.com/imagemapster/)我解决了OpenLayers的问题，图像现在可以平移和缩放 现在必须弄清楚如

我一直在研究同一个问题，办公室的办公桌平面图应根据办公桌的状态（空的、已分配的、热坐的等）以不同的颜色显示
除此之外，如果用户单击桌面，则应显示分配的同事/员工的详细信息
上述要求是使用image mapster jquery插件实现的
此外，还应提供缩放和平移。对于缩放和平移，我发现gzoom插件最适合我的要求。但是，当与image mapster插件一起使用时，它并没有像预期的那样工作
