无法将样式嵌入到从html文件呈现的aspose ppt中 [英] Unable to embed styling in aspose ppt which is rendered from html file

问题描述

我使用aspose java库将html转换为ppt。但是，我无法生成类似（填充，背景颜色等）的样式，而像（颜色，字体大小）等样式工作得很好，请查看代码..

  public class poi {
 
 public static void main（String [] args）throws Exception {
 
 //文档目录的路径。 
 String dataDir = Utils.getDataDir（poi.class）; 
 
 //创建空演示文稿实例
演示文稿pres =新演示文稿（）; 
 
 //访问演示文稿的默认第一张幻灯片
 ISlide slide = pres.getSlides（）。get_Item（0）; 
 
 //添加自选图形以适应HTML内容
 IAutoShape ashape = slide.getShapes（）。addAutoShape（ShapeType.Rectangle，50，150，300，150）; 
 
 ashape.getFillFormat（）。setFillType（FillType.NoFill）; 
 
 //将文本框添加到形状
 ashape.addTextFrame（）; 
 
 //清除添加文本框中的所有段落
 ashape.getTextFrame（）。getParagraphs（）。clear（）; 
 
 //使用InputStream加载HTML文件
 InputStream inputStream = new FileInputStream（dataDir +file.html）; 
 Reader reader = new InputStreamReader（inputStream）; 
 
 int data = reader.read（）; 
 String content = ReadFile（dataDir +file.html）; 
 
 //在文本框中添加来自HTML流式阅读器的文本
 ashape.getTextFrame（）。getParagraphs（）。addFromHtml（content）; 
 
 //保存表示
 pres.save（dataDir +output.pptx，SaveFormat.Pptx）; 
 
 
 
 $ b public static String ReadFile（String FileName）throws Exception {
 
 File file = new File（FileName）; 
 StringBuilder contents = new StringBuilder（）; 
 BufferedReader reader = null; 
 
尝试{
 reader = new BufferedReader（new FileReader（file））; 
 String text = null; $（$ text = reader.readLine（））！= null）{
 contents.append（text）.append（System .getProperty（ line.separator））; 
} 
} catch（IOException e）{
 e.printStackTrace（）; 
} finally {
 try {
 if（reader！= null）{
 reader.close（）; 
} 
} catch（IOException e）{
 e.printStackTrace（）; 
返回null; 
} 
} 
 
 return contents.toString（）; 
 
} 
 
} 
  

看到我正在加载具有内联样式的html文件，但我无法完成大部分要加载的CSS元素。任何建议？

解决方案

@Balchandar Reddy，

您的要求，并希望目前Aspose.Slides支持基本文本导入以及使用Aspose.Slides生成的演示文稿中的有限标记支持。我请求您请分享所需的HTML，并使用您希望在Aspose.Slides中支持的所需标签。我将与我们的产品团队讨论这个问题，并将其添加为问题跟踪系统中的新功能请求。

I am converting html to ppt using aspose java library. But, I couldn't generate styles like (padding,background-color,etc) whereas styles like(color,font-size) are working just fine,have a look at the code..

 public class poi {

        public static void main(String[] args) throws Exception {

            // The path to the documents directory.
            String dataDir = Utils.getDataDir(poi.class);

            // Create Empty presentation instance
            Presentation pres = new Presentation();

            // Access the default first slide of presentation
            ISlide slide = pres.getSlides().get_Item(0);

            // Adding the AutoShape to accommodate the HTML content
            IAutoShape ashape = slide.getShapes().addAutoShape(ShapeType.Rectangle,  50, 150, 300, 150);

            ashape.getFillFormat().setFillType(FillType.NoFill);

            // Adding text frame to the shape
            ashape.addTextFrame("");

            // Clearing all paragraphs in added text frame
            ashape.getTextFrame().getParagraphs().clear();

            // Loading the HTML file using InputStream
            InputStream inputStream = new FileInputStream(dataDir + "file.html");
            Reader reader = new InputStreamReader(inputStream);

            int data = reader.read();
            String content = ReadFile(dataDir + "file.html");

            // Adding text from HTML stream reader in text frame
            ashape.getTextFrame().getParagraphs().addFromHtml(content);

            // Saving Presentation
            pres.save(dataDir + "output.pptx", SaveFormat.Pptx);


        }

        public static String ReadFile(String FileName) throws Exception {

            File file = new File(FileName);
            StringBuilder contents = new StringBuilder();
            BufferedReader reader = null;

            try {
                reader = new BufferedReader(new FileReader(file));
                String text = null;

                // repeat until all lines is read
                while ((text = reader.readLine()) != null) {
                    contents.append(text).append(System.getProperty("line.separator"));
                }
            } catch (IOException e) {
                e.printStackTrace();
            } finally {
                try {
                    if (reader != null) {
                        reader.close();
                    }
                } catch (IOException e) {
                    e.printStackTrace();
                    return null;
                }
            }

            return contents.toString();

        }

    }

As you can see I am loading the html file which has inline styling, but I couldn't quite make most of the css elements to load. Any suggestions?

解决方案

@Balchandar Reddy,

I have observed your requirements and like to share that at present Aspose.Slides support basic text import along with limited tag support in presentations generated using Aspose.Slides. I request you to please share the required HTML with desired tags for which you intend to have support in Aspose.Slides. I will discuss that with our product team and will add that as new feature request in our issue tracking system.

I am working as Support developer/ Evangelist at Aspose.
