Export a Math Formula

Introduction

You can export (download or save to the storage) math formulas in MathML format. You use mathMl subresource of portion resource for that. You can not export ordinary text portions for which MathParagraph property is not set. You will get an exception if you try to export such a portion.

API Information

API	Type	Description	Resource Link
/slides/{name}/slides/{slideIndex}/shapes/{shapeIndex}/paragraphs/{paragraphIndex}/portions/{portionIndex}/{format}	POST	Converts math formula to MathML or LaTeX format.	DownloadMathPortion
/slides/{name}/slides/{slideIndex}/shapes/{shapeIndex}/paragraphs/{paragraphIndex}/portions/{portionIndex}/{format}	PUT	Converts math formula to MathML or LaTeX format and saves result to the storage.	SaveMathPortion

Request Parameters

Parameter Name	HTTP Method(s)	Type	Optional/Required	Description
folder	POST/PUT	string (query)	Optional	Presentation folder.
storage	POST/PUT	string (query)	Optional	Presentation storage.
password	POST/PUT	string (header)	Optional	Presentation password.
outPath	PUT	string (query)	Required	A path to save the result.

In case of Amazon S3 storage folder path starts with Amazon S3 bucket name.

SDKs

Using an SDK (API client) is the quickest way for a developer to speed up the development. An SDK takes care of a lot of low-level details of making requests and handling responses and lets you focus on writing code specific to your particular project. Check out our GitHub repository for a complete list of Aspose.Slides Cloud SDKs along with working examples, to get you started in no time. Please check Available SDKs article to learn how to add an SDK to your project.

SDK Examples

string fileName = "MyPresentation.pptx";
int slideIndex = 2;
int shapeIndex = 3;
int paragraphIndex = 1;
int portionIndex = 1;
SlidesApi api = new SlidesApi("MyClientId", "MyClientSecret");

using Stream mathMl = api.DownloadMathPortion(fileName, slideIndex, shapeIndex, paragraphIndex, portionIndex, MathFormat.MathML);
using Stream fileStream = File.Open("equation.xml", FileMode.Create);
mathMl.CopyTo(fileStream);

Java

String fileName = "MyPresentation.pptx";
int slideIndex = 2;
int shapeIndex = 3;
int paragraphIndex = 1;
int portionIndex = 1;
SlidesApi api = new SlidesApi("MyClientId", "MyClientSecret");

File mathMl = api.downloadMathPortion(fileName, slideIndex, shapeIndex, paragraphIndex, portionIndex, MathFormat.MATHML, null, null, null);
System.out.println("The converted file was saved to " + mathMl.getPath());

PHP

use Aspose\Slides\Cloud\Sdk\Api\Configuration;
use Aspose\Slides\Cloud\Sdk\Api\SlidesApi;

$config = new Configuration();
$config->setAppSid("MyClientId");
$config->setAppKey("MyClientSecret");
$api = new SlidesApi(null, $config);

$fileName = "MyPresentation.pptx";
$slideIndex = 2;
$shapeIndex = 3;
$paragraphIndex = 1;
$portionIndex = 1;

$mathMl = $api->downloadMathPortion($fileName, $slideIndex, $shapeIndex, $paragraphIndex, $portionIndex, "MathML");
print("The converted file was saved to " . $mathMl->getPathname());

Python

import asposeslidescloud

from asposeslidescloud.configuration import Configuration
from asposeslidescloud.apis.slides_api import SlidesApi

configuration = Configuration()
configuration.app_sid = 'MyClientId'
configuration.app_key = 'MyClientSecret'
api = SlidesApi(configuration)

file_name = "MyPresentation.pptx"
slide_index = 2
shape_index = 3
paragraph_index = 1
portion_index = 1

mathMl = api.download_math_portion(file_name, slide_index, shape_index, paragraph_index, portion_index, "MathML")
print('The converted file was saved to ' + mathMl)

Node.js

const CloudSdk = require("asposeslidescloud");
const fs = require("fs");
const api = new CloudSdk.SlidesApi("MyClientId", "MyClientSecret");

const fileName = "MyPresentation.pptx";
const slideIndex = 2;
const shapeIndex = 3;
const paragraphIndex = 1;
const portionIndex = 1;

api.downloadMathPortion(fileName, slideIndex, shapeIndex, paragraphIndex, portionIndex, "MathML").then(result => {
    fs.writeFile("equation.xml", result.body, (err) => {
        if (err) throw err;
    });
});

cfg := asposeslidescloud.NewConfiguration()
cfg.AppSid = "MyClientId"
cfg.AppKey = "MyClientSecret"
api := asposeslidescloud.NewAPIClient(cfg)

fileName := "MyPresentation.pptx"
var slideIndex int32 = 2
var shapeIndex int32 = 3
var paragraphIndex int32 = 1
var portionIndex int32 = 1

mathMl, _, e := api.SlidesApi.DownloadMathPortion(fileName, slideIndex, shapeIndex, paragraphIndex, portionIndex, "MathML", "", "", "")
if e != nil {
    fmt.Printf("Error: %v.", e)
    return
