PPTShow is an open source free Java generated PPT toolkit .
It is completely independent of other programs on any system to help users use code to generate PPT files .
But PPT to generate pictures , PPT to generate video functions are achieved by calling Microsoft Office , so only available under Windows .
- adding pages to the PPT;
- adding text, graphics, line segments, pictures to the page;
- text support for sub-paragraph text, and support for multiple styles of text appearing in the same line;
- support background music;
- support for PPT page background style settings;
- support for element and page animation, element animation support for order adjustment and moment setting;
- support for common element style settings;
- support PPT to video and PPT to picture in Windows environment (please make sure Microsoft Office is installed and activated)
- can only generate pptx files, do not support generating ppt files
- not recommended to use PPTShow to read PPT files (reading is still in demo state, not suitable for production environment)
- do not support table elements at the moment
Our current plans that are not yet developed are:
- table element support
- embedded font support
Q: Can it be used for commercial purposes?
A: PPTShow follows the Apache License 2.0 open source agreement which allows users to use it for purposes including, but not limited to, commercial use and personal study use.
Q: Is it possible to generate PPT documents in Linux environment?
A：Support
Q：Does the PPT generate images with messy Chinese or default fonts?
A: No, we generate pictures by calling the system Office, so there is no need to worry about similar problems.
Q: Is it possible to set the animation order of elements?
A: We support setting the order and common operations such as appearing at the same time and appearing after the previous animation is finished.
Q：Does PPTShow guarantee the availability or take responsibility for the loss caused by code problems?
A: PPTShow does not guarantee the usability of the project and is not responsible for any loss, please test the function by yourself before using it.
This tutorial will guide you through the Java code to generate a PPT file containing HelloWorld
You can introduce jar packages by maven or by importing them manually
<dependency>
<groupId>cc.pptshow</groupId>
<artifactId>pptshow</artifactId>
<version>1.3</version>
</dependency>Download address: https://s01.oss.sonatype.org/service/local/repositories/releases/content/cc/pptshow/pptshow/1.3/pptshow-1.3.jar
Create a new Java class file named Main.
Copy the following code into the project and run it.
You'll have a PPT file containing HelloWorld!
import cc.pptshow.ppt.domain.*;
import cc.pptshow.ppt.element.impl.*;
import cc.pptshow.ppt.show.PPTShow;
import cc.pptshow.ppt.show.PPTShowSide;
public class Main {
public static void main(String[] args) {
//Create a new PPT object
PPTShow pptShow = PPTShow.build();
//Create a new PPT page
PPTShowSide side = PPTShowSide.build();
//Create an in-line text object with the text set to Hello World
PPTInnerText pptInnerText = PPTInnerText.build("Hello World");
//Create an in-line text style object so that the text color is red
PPTInnerTextCss pptInnerTextCss = PPTInnerTextCss.build().setColor("FF00000");
//Binding in-line text and style objects
pptInnerText.setCss(pptInnerTextCss);
//Create a line text object from in-line text and create a text object from a line text object
PPTText pptText = PPTText.build(PPTInnerLine.build(pptInnerText));
//Adding text objects to a PPT page
side.add(pptText);
//Add PPT page inside PPT
pptShow.add(side);
//Output to file
pptShow.toFile("C:/Users/xxx/Desktop/test.pptx");
}
}If things go well, you will get a file similar to the one below
PPTShow is different from common PPT generation programs such as POI, PPTShow almost completely shields the underlying XML code of PPT itself.
PPTShow considers each small indivisible element as an object, and the objects at different levels are nested with each other to form the whole PPT.
For example, as shown in the figure below, we consider the whole of PPT, different pages, and various elements in the pages are all one object.
Each element object has a corresponding style sheet object, and style binding can be achieved by means of element object.setCss(style sheet object).
| Element Object | Element Meaning | Style Sheet Object |
|---|---|---|
| PPTShowSide | PPT page | PPTSideCss |
| PPTImg | PPT images | PPTImgCss |
| PPTShape | PPT graphics | PPTShapeCss |
| PPTLine | PPT Line Segment | PPTLineCss |
| PPTText | PPT Text | PPTTextCss |
| PPTInnerLine | Paragraphs in PPT text | PPTInnerLineCss |
| PPTInnerText | A style minimum unit in a PPT text paragraph | PPTInnerTextCss |
- PPTShow objects need to manually call
close()method to delete temporary files after use - All element objects and style sheet objects in this project implement the
cloneableinterface, and are deep clones.
The PPTShow object represents a PPT file, and the system builds the necessary components of the file in the temporary directory and outputs the assembled file to the specified location when the user specifies the output.
Therefore you must perform the close operation manually to delete the temporary directory files, otherwise the more temporary directory files are piled up may lead to insufficient disk space.
You can create a PPTShow object in the following two ways, which do not differ in any way.
PPTShow pptShow = PPTShow.build();PPTShow pptShow = new PPTShow();PPTShowSide is the PPT page object, which will be mentioned later in the document.
Insert at the end of the document page:
void add(PPTShowSide pptShowSide)Insert into a page in the middle of the document:

*/
void add(PPTShowSide pptShowSide, int indexId)Generate a PPT file in pptx format based on PPTShow content
/**
* path Output path, please end with .pptx
*/
void toFile(String path)The cache will be cleared after closing the object, and the closed object cannot generate files
void close()PPT page object represents a page of PPT, a page in which usually consists of many elements, many pages make up the PPT
You can create a PPTShowSide object in the following two ways, which do not differ in any way.
PPTShowSide pptShowSide = PPTShowSide.build();PPTShowSide pptShowSide = new PPTShowSide();Elements follow the index of the smaller elements in the lower level, the index of the larger elements in the upper level
void add(PPTElement pptElement)/**
* indexId Indicates that the index of the specified page is to be inserted, and the index starts from 0
*/
void add(PPTElement pptElement, int indexId)void addAll(List<PPTElement> pptElements)Read the current element list information by Get method

PPTText indicates a PPT text element, note that it is the text element as a whole, not a part of it, for example, the dotted box area in the figure below is a PPT text
If we want to include different paragraphs in a PPText object, as in the effect above, which contains two paragraphs, respectively PPTShow is a free open source Java native generation of PPT toolkit. and support the 2010 version of the new features of PPT , does not rely on any third-party components , Linux, Windows can be used smoothly .
Each of these paragraphs is a PPTInnerLine object.
There may also be multiple text rendering styles in a paragraph, which are close together without line breaks.
For example, there is a difference between 2010 version and the text before and after it, which is equivalent to a PPTInnerLine object containing three PPTInnerText objects, the first of which has the same style as the third, and the second has a bold and red special effect. (As shown in the figure below, each part of the wireframe represents a PPTInnerText object)
You can create a PPTText object without any difference between the two ways by:
PPTText pptText = new PPTText();PPTText pptText = PPTText.build();You can also bind the PPTInnerLine object collection directly at creation time:
When there is only one PPTInnerLine, you can create the PPTText object in the following way, without any difference between the two ways:
PPTText pptText = new PPTText(PPTInnerLine line);PPTText pptText = PPTText.build(PPTInnerLine line);When there are more than one, the PPText object can be created in the following way, without any difference between the two ways:
PPTText pptText = new PPTText(List<PPTInnerLine> lineList);PPTText pptText = PPTText.build(List<PPTInnerLine> textList);You can also bind style files directly at the time of creation: the
PPTText pptText = new PPTText(PPTInnerLine line, PPTTextCss css);PPTText pptText = PPTText.build(PPTInnerLine line, PPTTextCss css);PPTText pptText = new PPTText(List<PPTInnerLine> lineList, PPTTextCss css);PPTText pptText = PPTText.build(List<PPTInnerLine> textList, PPTTextCss css);double findMinWidthSize()The minimum required width for each paragraph without line breaks
double findMinHeightSize()Get the minimum required height value under the current width.
In fact, even if the height in the set style is smaller than the minimum height, the text will automatically overflow and will not affect the display.
String findAllText()Get all the text information in all paragraphs and all text within paragraphs of the text object.
Return information contains line breaks, you can use line breaks to distinguish paragraph information, but the text within the paragraph can not be distinguished.
Example:
The above PPText object calls the findAllText() method and gets the following text:
PPTShow is a free open source Java native generation of PPT toolkit.
support the 2010 version of the new features of PPT.
Add a paragraph at the end:

*/
PPTInnerLine pptInnerLine = PPTInnerLine buildEmptyLine(int num);You can also bind the PPTInnerText object collection directly at the time of creation:
When there is only one PPTInnerText, you can create the PPTInnerLine object in the following way, without any difference between the two ways:
PPTInnerLine pptInnerLine = new PPTInnerLine(PPTInnerText text);PPTInnerLine pptInnerLine = PPTInnerLine.build(PPTInnerText text);When there are more than one, the PPTInnerLine object can be created in the following way, without any difference between the two ways:
