PDF samples

Basics

Suggested code sample

First, you must create the webservice object:

OKMWebservices ws = OKMWebservicesFactory.getInstance(host);

Then should login using the method "login". You can access the "login" method from webservice object "ws" as is shown below:

ws.login(user, password);

Once you are logged with the webservices the session is kept in the webservice Object. Then you can use the other API method

At this point you can use all the Pdf methods from "pdf" class as is shown below:

InputStream is = ws.pdf.getImage("e7d6860a-7e0b-4823-bd3d-75f88be1eedf", 1);

Methods

getImage

Description:

MethodReturn valuesDescription

getImage(String uuid, int page, String size)

InputStream

Returns the image of a page.

The document must be a PDF or convertible to PDF.

The default value of size parameter is "150". The value is in pixels.

The value of the uuid is the UUID of the document.

The page is the number of the page in the document starting from the value "1".

The size value is optional. When set is used to resize the image of the page, otherwise is used the default value.

Example:

package com.openkm;

import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;

import org.apache.commons.io.IOUtils;

import com.openkm.sdk4j.OKMWebservicesFactory;
import com.openkm.sdk4j.impl.OKMWebservices;

public class Test {

    public static void main(String[] args) {
        String host = "http://localhost:8080/openkm";
        String user = "okmAdmin";
        String password = "admin";
        OKMWebservices ws = OKMWebservicesFactory.getInstance(host);

        try {
            ws.login(user, password);

            InputStream is = ws.pdf.getImage("e7d6860a-7e0b-4823-bd3d-75f88be1eedf", 1, null);
            OutputStream fos = new FileOutputStream("/home/openkm/page-1.png");
            IOUtils.copy(is, fos);
            IOUtils.closeQuietly(is);
            IOUtils.closeQuietly(fos);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

split

Description:

MethodReturn valuesDescription
split(String uuid, String dstId, String baseName, List<Integer> pages)

boolean

Return true when the pages of the document have been split.

The document must be a PDF or convertible to PDF.

The value of the uuid is the UUID of the document.

The value of baseName is the base name to create a split document, for example, if baseName value is "test" and pages value is "1,3", the files created will be "test-001.pdf" and "test-003.pdf".

The value of pages is the number of pages to be split.

Example:

package com.openkm;

import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.ArrayList;

import com.openkm.sdk4j.impl.OKMWebservices;

public class Test {

    public static void main(String[] args) {
        String host = "http://localhost:8080/openkm";
        String username = "okmAdmin";
        String password = "admin";
        OKMWebservices ws = OKMWebservicesFactory.getInstance(host);

        try {
            ws.login(username, password);
            List<Integer> pages = new ArrayList<>();
            pages.add(2);
            pages.add(3);
            boolean value = ws.pdf.split("e7d6860a-7e0b-4823-bd3d-75f88be1eedf", "0be057f1-efac-4e09-9c10-e7f27c731442", "split", pages);
            if (value) {
                System.out.println("split done");
            }

    }
}
