从PPTX格式与Apache POI提取图像 [英] Extracting images from pptx with apache poi

问题描述

我想从百分点与Apache POI文件，存在没有问题的幻灯片中提取，但现在我打算开 PPTX 文件和做的一样，没有人知道如何??

这是code提取百分点文件图片：

 公共ImageIcon的显示（）抛出Ĵ$ P $ {psentationException    背景背景;
    背景=幻灯片[电流] .getBackground（）;
    填写F = background.getFill（）;
    色色= f.getForegroundColor（）;
    维维= ppt.getPageSize（）;
    形状=幻灯片[现行] .getShapes（）;
    IMG的BufferedImage =新的BufferedImage（dimension.width，dimension.height，BufferedImage.TYPE_INT_RGB）;
    Graphics2D的图形= img.createGraphics（）;
    graphics.setPaint（颜色）;
    graphics.fill（新Rectangle2D.Float（0，0，dimension.width，dimension.height））;
    幻灯片[现行] .draw（图形）;
    ImageIcon的图标=新的ImageIcon（IMG）;    返回图标;
}
 

解决方案

下面是做到这一点在VBS的方式，也许你可以转换：

 子SaveAllPictures（）
    昏暗AP作为presentation：设置AP =活动presentation
    昏暗savePath作为字符串
    savePath =C：\\用户\\我\\桌面\\文件\\
    昏暗我作为整数
    昏暗的SL作为幻灯片
    昏暗的SH作为形状
    对于每个SL在ap.Slides
        对于每个SH在sl.Shapes
            如果sh.Type = msoPicture然后
                sh.Export路径名称：= savePath＆安培; sh.Name＆安培; CStr的（ⅰ）及png格式，过滤器：= ppShapeFormatPNG
                I = I + 1
            万一
        下一个
    下一个
结束小组
 

I'm trying to extract slides from a ppt file with Apache POI, there is no problem in that, but now I intend to open pptx files and do the same, does anyone knows how to??

this is the code to extract images from ppt files:

public ImageIcon display() throws JPresentationException { 

    Background background; 
    background = slides[current].getBackground(); 
    Fill f = background.getFill(); 
    Color color = f.getForegroundColor(); 
    Dimension dimension = ppt.getPageSize(); 
    shapes = slides[current].getShapes(); 
    BufferedImage img = new BufferedImage(dimension.width, dimension.height, BufferedImage.TYPE_INT_RGB); 
    Graphics2D graphics = img.createGraphics(); 
    graphics.setPaint(color); 
    graphics.fill(new Rectangle2D.Float(0, 0, dimension.width, dimension.height)); 
    slides[current].draw(graphics); 
    ImageIcon icon = new ImageIcon(img); 

    return icon; 
}

解决方案

Here's the way to do it in VBS, Maybe you can convert :

Sub SaveAllPictures()
    Dim ap As Presentation: Set ap = ActivePresentation
    Dim savePath As String
    savePath = "C:\Users\me\Desktop\files\"
    Dim i As Integer
    Dim sl As Slide
    Dim sh As Shape
    For Each sl In ap.Slides
        For Each sh In sl.Shapes
            If sh.Type = msoPicture Then
                sh.Export PathName:=savePath & sh.Name & CStr(i) & ".png", Filter:=ppShapeFormatPNG
                i = i + 1
            End If
        Next
    Next
End Sub
