Word文档中图片坐标怎么获取于实际开发期间我们时常得去处理Word文档里的图片像是把图片提取出来对排版予以调整亦或是进行自动化校验。然而好多人在获取图片的坐标位置之际卡住了这事是由于Word的图片位置信息藏得相对较深并非如文本内容那般直观。实际上借助Apache POI库能够读取到这些数据重点在于寻找到正确的对象以及属性。有关于.doc格式的老版Word文档其图片信息被存储于HWPF的文档模型之中。你得先对Word文档展开解析接着去全面遍历该文档里的所有图片对象。每一张图片都与特定的字符位置或者段落存在绑定关系坐标信息一般是被保存在图片的锚点属性当中像是水平对齐以及垂直偏移之类的。然而需要留意的是老版格式的坐标单位是缇twips得转换为像素之后方可使用。对于新版的Word的.docx格式情况会稍微简单一点。使用XWPF库读取文档之后能够找到内嵌的图片或者浮动的图片。浮动的图片具有明确的坐标属性像上下左右的位置、相对页面还是段落之类的。而内嵌的图片则要依据所在段落的布局信息来推算坐标这要综合行高和段落间距进行计算。实际操作中需要注意哪些坑当你切实着手去开展写代码这一行为时存在着几个地方是甚易出现问题的。首当其冲便是单位换算方面Word所具备的默认度量单位乃是缇或者EMU然而前端或者GUI一般所采用的却是像素因而需要进行统一的转换操作。其次便是图片类型方面存在着一些图片属于嵌入式的还有一些是浮动式的其为获取坐标的方式全然不一样所以绝不能够将代码逻辑进行混用。比如说要是你运用POI的XWPF去读取docx文件从而获取图片的坐标那就需要首先把图片所在的段落对象给拿到手接着借助getCTPicture()方法去访问底层的XML对象随后再从XML里解析出cNvPr或者spPr标签下面的位置信息。这个流程涉及到数量众多的XML解析操作因而建议将其封装成为一个工具方法。还存在一个容易被忽视的要点 Word里的图片存在旋转 、缩放等变化 这些同样会对实际坐标的计算产生影响。要是你需要精准的左上角坐标 得把图片的原始尺寸与变换矩阵结合起来进行计算 不然获取到的坐标会出现偏差 另外 要是文档里有文本框或者组图 图片的坐标是相对于父容器而非页面的 这会致使坐标产生错位。实用代码思路和建议对于写代码这件事我给予你这样的建议首先要去判断文档格式接着从中选择匹配适宜的POI类随后要将所有图片对象予以定位逐个去提取坐标最后依据实际所需转换单位。要是仅仅进行普通的坐标提取操作那么能够运用POI的getAnchor()方法该方法会直接把图片的锚点位置信息返回。在进行批量处理大量文档的情形下要记住做好异常的处理工作由于会存在一些图片或许缺失坐标信息又或许格式不兼容的状况。能够借助POI的isPicture() 方法先行过滤以此避免出现空指针。假如你有获取更高精度的需要像是去获取图片边缘的坐标那么可以通过合并getDescriptor()里的尺寸数据以及锚点坐标进而进行计算。https://www.hongxiu.com/booklist/1486042https://www.hongxiu.com/booklist/1486041https://www.hongxiu.com/booklist/1486040https://www.hongxiu.com/booklist/1486039https://www.hongxiu.com/booklist/1486038https://www.hongxiu.com/booklist/1486037https://www.hongxiu.com/booklist/1486036https://www.hongxiu.com/booklist/1486035https://www.hongxiu.com/booklist/1486034https://www.hongxiu.com/booklist/1486033https://www.hongxiu.com/booklist/1486032https://www.hongxiu.com/booklist/1486031https://www.hongxiu.com/booklist/1486030https://www.hongxiu.com/booklist/1486029https://www.hongxiu.com/booklist/1486028https://www.hongxiu.com/booklist/1486027https://www.hongxiu.com/booklist/1486026https://www.hongxiu.com/booklist/1486024https://www.hongxiu.com/booklist/1486025https://www.hongxiu.com/booklist/1486023https://www.hongxiu.com/booklist/1486022https://www.hongxiu.com/booklist/1486021https://www.hongxiu.com/booklist/1486020https://www.hongxiu.com/booklist/1486019https://www.hongxiu.com/booklist/1486018https://www.hongxiu.com/booklist/1486017https://www.hongxiu.com/booklist/1486016https://www.hongxiu.com/booklist/1486015https://www.hongxiu.com/booklist/1486013https://www.hongxiu.com/booklist/1486014https://www.hongxiu.com/booklist/1486012https://www.hongxiu.com/booklist/1486011https://www.hongxiu.com/booklist/1486010https://www.hongxiu.com/booklist/1486009https://www.hongxiu.com/booklist/1486008https://www.hongxiu.com/booklist/1486007https://www.hongxiu.com/booklist/1486006https://www.hongxiu.com/booklist/1486005https://www.hongxiu.com/booklist/1486004https://www.hongxiu.com/booklist/1486003https://www.hongxiu.com/booklist/1486002https://www.hongxiu.com/booklist/1486001https://www.hongxiu.com/booklist/1486000https://www.hongxiu.com/booklist/1485999https://www.hongxiu.com/booklist/1485998https://www.hongxiu.com/booklist/1485997https://www.hongxiu.com/booklist/1485996https://www.hongxiu.com/booklist/1485995https://www.hongxiu.com/booklist/1485994https://www.hongxiu.com/booklist/1485993https://www.hongxiu.com/booklist/1485992https://www.hongxiu.com/booklist/1485991https://www.hongxiu.com/booklist/1485990https://www.hongxiu.com/booklist/1485989https://www.hongxiu.com/booklist/1485988https://www.hongxiu.com/booklist/1485987https://www.hongxiu.com/booklist/1485986https://www.hongxiu.com/booklist/1485985https://www.hongxiu.com/booklist/1485984https://www.hongxiu.com/booklist/1485983https://www.hongxiu.com/booklist/1485982https://www.hongxiu.com/booklist/1485981https://www.hongxiu.com/booklist/1485980https://www.hongxiu.com/booklist/1485979https://www.hongxiu.com/booklist/1485978https://www.hongxiu.com/booklist/1485977https://www.hongxiu.com/booklist/1485976https://www.hongxiu.com/booklist/1485975https://www.hongxiu.com/booklist/1485974https://www.hongxiu.com/booklist/1485973https://www.hongxiu.com/booklist/1485972https://www.hongxiu.com/booklist/1485971https://www.hongxiu.com/booklist/1485970https://www.hongxiu.com/booklist/1485969https://www.hongxiu.com/booklist/1485968https://www.hongxiu.com/booklist/1485967https://www.hongxiu.com/booklist/1485966https://www.hongxiu.com/booklist/1485965https://www.hongxiu.com/booklist/1485964https://www.hongxiu.com/booklist/1485963https://www.hongxiu.com/booklist/1485962https://www.hongxiu.com/booklist/1485961https://www.hongxiu.com/booklist/1485960https://www.hongxiu.com/booklist/1485959https://www.hongxiu.com/booklist/1485958https://www.hongxiu.com/booklist/1485957https://www.hongxiu.com/booklist/1485956https://www.hongxiu.com/booklist/1485955https://www.hongxiu.com/booklist/1485954https://www.hongxiu.com/booklist/1485953https://www.hongxiu.com/booklist/1485952https://www.hongxiu.com/booklist/1485951https://www.hongxiu.com/booklist/1485950https://www.hongxiu.com/booklist/1485949https://www.hongxiu.com/booklist/1485948https://www.hongxiu.com/booklist/1485947https://www.hongxiu.com/booklist/1485946https://www.hongxiu.com/booklist/1485945https://www.hongxiu.com/booklist/1485944https://www.hongxiu.com/booklist/1485943https://www.hongxiu.com/booklist/1485942https://www.hongxiu.com/booklist/1485941https://www.hongxiu.com/booklist/1485940https://www.hongxiu.com/booklist/1485939https://www.hongxiu.com/booklist/1485938https://www.hongxiu.com/booklist/1485937https://www.hongxiu.com/booklist/1485936https://www.hongxiu.com/booklist/1485935https://www.hongxiu.com/booklist/1485934https://www.hongxiu.com/booklist/1485933https://www.hongxiu.com/booklist/1485932https://www.hongxiu.com/booklist/1485931https://www.hongxiu.com/booklist/1485930https://www.hongxiu.com/booklist/1485929https://www.hongxiu.com/booklist/1485928https://www.hongxiu.com/booklist/1485927https://www.hongxiu.com/booklist/1485926https://www.hongxiu.com/booklist/1485925https://www.hongxiu.com/booklist/1485924https://www.hongxiu.com/booklist/1485923https://www.hongxiu.com/booklist/1485922https://www.hongxiu.com/booklist/1485921https://www.hongxiu.com/booklist/1485
