最近做多点查询，需要在项目中展示word excel ppt 和pdf 思路是转换为图片多方查询，成功使用aspon完成，走了很多弯路，在此记录，方便后来人

准备工作将以下.dll导入unity的plugins文件夹资源及完整项目可以通过文章结尾的链接免费下载在这里插入图片描述 word代码

using System.Collections; using System.Collections.Generic; using UnityEngine; using Aspose.Words; using Aspose.Words.Saving; using System.IO; using UnityEngine.UI; /// /// 加载word /// public class LoadWordTest : MonoBehaviour { public static LoadWordTest Instance; public GameObject imageprefab; public Transform content; private void Start() { Instance = this; } /// /// 加载Word并转换为图片 /// public void LoadWordGo(string path) { //清理content下的旧物体 for (int i = 0; i iso.PageIndex = i; //声明内存流，将图片转换为内存流，再由流转换为byte数组，然后用texture2d加载byte数组 using (MemoryStream ms = new MemoryStream()) { doc.Save(ms, iso); byte[] buff = new byte[ms.Length]; ms.Seek(0, SeekOrigin.Begin); ms.Read(buff, 0, (int)ms.Length); //注意这个iamge的命名空间为system.drawing不是unity.ui,这个图片的目的是提供图片的宽高 System.Drawing.Image sizeImage = System.Drawing.Image.FromStream(ms); Texture2D texture2D = new Texture2D(sizeImage.Width, sizeImage.Height); texture2D.LoadImage(buff); Image image = Instantiate(imageprefab, content).GetComponent(); //根据转化出来的图片的大小设置unity image的大小 image.rectTransform.sizeDelta = new Vector2(sizeImage.Width, sizeImage.Height); //用texture2d为精灵赋值 image.sprite = Sprite.Create(texture2D, new Rect(0, 0, texture2D.width, texture2D.height), Vector2.zero); } } } }

excel代码

using System.Collections; using System.Collections.Generic; using UnityEngine; using System.Drawing.Imaging; using Aspose.Cells; using Aspose.Cells.Rendering; using System.IO; using UnityEngine.UI; /// /// 加载excel并转为图片 /// public class LoadExcelTest : MonoBehaviour { public static LoadExcelTest Instance; public GameObject imageprefab; public Transform content; private void Start() { Instance = this; } /// /// 加载excel /// public void LoadExcelGO(string path) { //清理content下的旧物体 for (int i = 0; i sr.ToImage(0, ms); byte[] buff = new byte[ms.Length]; ms.Seek(0, SeekOrigin.Begin); ms.Read(buff, 0, (int)ms.Length); //注意这个iamge的命名空间为system.drawing不是unity.ui,这个图片的目的是提供图片的宽高 System.Drawing.Image sizeImage = System.Drawing.Image.FromStream(ms); Texture2D texture2D = new Texture2D(sizeImage.Width, sizeImage.Height); texture2D.LoadImage(buff); Image image = Instantiate(imageprefab, content).GetComponent(); //根据转化出来的图片的大小设置unity image的大小 image.rectTransform.sizeDelta = new Vector2(sizeImage.Width, sizeImage.Height); //用texture2d为精灵赋值 image.sprite = Sprite.Create(texture2D, new Rect(0, 0, texture2D.width, texture2D.height), Vector2.zero); } } }

ppt代码

using Aspose.Slides; using System; using System.Drawing.Imaging; using System.IO; using UnityEngine; using UnityEngine.UI; public class LoadPPTTest : MonoBehaviour { public static LoadPPTTest Instance; public GameObject imageprefab; public Transform content; private void Start() { Instance = this; } public void LoadPPTGO(string pptPath) { //清理content下的旧物体 for (int i = 0; i ISlide slide = presentation.Slides[i]; var bitmap = slide.GetThumbnail(1f, 1f); //声明内存流，将图片转换为内存流，再由流转换为byte数组，然后用texture2d加载byte数组 using (MemoryStream ms = new MemoryStream()) { bitmap.Save(ms, ImageFormat.Jpeg); byte[] buff = new byte[ms.Length]; ms.Seek(0, SeekOrigin.Begin); ms.Read(buff, 0, (int)ms.Length); //注意这个iamge的命名空间为system.drawing不是unity.ui,这个图片的目的是提供图片的宽高 System.Drawing.Image sizeImage = System.Drawing.Image.FromStream(ms); Texture2D texture2D = new Texture2D(sizeImage.Width, sizeImage.Height); texture2D.LoadImage(buff); Image image = Instantiate(imageprefab, content).GetComponent(); //根据转化出来的图片的大小设置unity image的大小 image.rectTransform.sizeDelta = new Vector2(sizeImage.Width, sizeImage.Height); //用texture2d为精灵赋值 image.sprite = Sprite.Create(texture2D, new Rect(0, 0, texture2D.width, texture2D.height), Vector2.zero); } } } }

pdf代码

using Aspose.Pdf; using Aspose.Pdf.Devices; using System.Collections; using System.Collections.Generic; using System.Drawing; using System.IO; using UnityEngine; /// /// PDF转图片 /// public class LoadPDFTest : MonoBehaviour { public static LoadPDFTest Instance; public GameObject imageprefab; public Transform content; private void Start() { Instance = this; } /// /// 加载PDF /// public void LoadPDFGo(string path) { //清理content下的旧物体 for (int i = 0; i //PngDevice pngDevice = new PngDevice((int)pdf.Pages[i].PageInfo.Width,(int)pdf.Pages[i].PageInfo.Height); PngDevice pngDevice = new PngDevice((int)pdf.Pages[i].PageInfo.Width*2,(int)pdf.Pages[i].PageInfo.Height*2); //声明内存流，将图片转换为内存流，再由流转换为byte数组，然后用texture2d加载byte数组 using (MemoryStream ms = new MemoryStream()) { pngDevice.Process(pdf.Pages[i], ms); byte[] buff = new byte[ms.Length]; ms.Seek(0, SeekOrigin.Begin); ms.Read(buff, 0, (int)ms.Length); //注意这个iamge的命名空间为system.drawing不是unity.ui,这个图片的目的是提供图片的宽高 System.Drawing.Image sizeImage = System.Drawing.Image.FromStream(ms); Texture2D texture2D = new Texture2D(sizeImage.Width, sizeImage.Height); texture2D.LoadImage(buff); UnityEngine.UI.Image image = Instantiate(imageprefab, content).GetComponent(); //根据转化出来的图片的大小设置unity image的大小 image.rectTransform.sizeDelta = new Vector2(sizeImage.Width, sizeImage.Height); //用texture2d为精灵赋值 image.sprite = Sprite.Create(texture2D, new Rect(0, 0, texture2D.width, texture2D.height), Vector2.zero); } } } }

遇到的问题： 1 程序在编辑器运行正常，打包(开发构建)出来后报NotSupportedException: Encoding XXX data ,这是因为字符集的问题，找到untiy的安装目录 Editor/Data/MonoBleedingEdge/lib/mono/unityjit里找到 I18N开头的几个.dll，拖进项目的plugins文件夹里就行，注意在mono下的其他文件夹里也有这几个.dll，但是体积都比较小，有些拖进plugins里不能解决打包报错的问题，估计是没有unityjit里的全，unityjit里这几个文件的体积是最大的 2 运行后，转换出来的图片最上方有水印，因为aspon需要破解，目前我的演示中已经使用破解版，没有水印了
