Time Narration
00:01 Welcome to the spoken tutorial on LibreOffice Draw - Basics of Layers and Password Encryption PDF.
00:08 In this tutorial, you will learn the basics of layers.
00:12 You will also learn How to protect a Draw file
00:15 Using password encryption
00:18 Export it as PDF.
00:20 Here we are using Ubuntu Linux version 10.04 as our operating system and LibreOffice Suite version 3.3.4.
00:30 Let us open the file Route Map.
00:33 What are Layers?
00:34 Layers are like transparent sheets, placed one on the top of another.
00:40 There are three layers to every Draw file.
00:43 The Layout layer is displayed by default.


00:46 This is where we create most of our graphics.
00:50 The Control layer is used to store control elements such as buttons and forms.
00:56 The Dimensions layer is used to depict dimension lines or measurement lines for complex drawings.
01:03 For example, a drawing of a house must contain exact measurements of walls, positions of electrical wiring and so on.
01:16 Let’s print three maps that show the route from the House to the School.
01:23 Let’s call them Map 1, Map 2 and Map 3.
01:28 Map 1, shows all the landmarks in the area.
01:32 In Map 2, let’s show all the objects except the two Lakes, the Stadium and the Commercial Complex.
01:40 In Map 3, let’s show all the objects except the Park.
01:45 Do we need to create three separate maps to show these?
01:49 No, Draw provides a solution to this with the help of Layers.
01:54 This way, there can be only one map file with many layers of information.
01:59 We can print or view a combination of layers using one Draw page.
02:06 Let us add some layers to the RouteMap.
02:09 Click on Layout layer.
02:11 Right click and select Insert layer.
02:15 The Insert layer dialog box appears.
02:18 In the “Name” field, type “Layer four”.
02:21 You can add any title and description that is relevant to your drawing.
02:26 Check the boxes “Visible” and “Printable”.
02:30 Click OK to exit the dialog box.
02:33 Click on Layout layer once again.
02:36 On the Draw page, select the map and ungroup it.
02:40 Now let us select the Lakes.
02:43 Press the Shift key and select the Stadium and the Commercial complex.


02:48 Next right-click and select Cut.
02:51 Then click on “Layer four” layer and paste them.
02:55 They are pasted in the same positions as in the Layout layer.
03:00 Click Layer Four once again.
03:03 Right-click to view the context menu and select Modify Layer.
03:08 The Modify Layer dialog box appears.
03:11 Uncheck the box “Visible”. Click OK.
03:14 Objects in Layer Four are no longer visible.
03:18 The objects are present physically but are not visible.
03:22 Click Layout Layer. If the tab is not seen, then press the left arrow button till the Layout layer is visible.
03:31 We have our Map 2! In the same manner, we can create Map 3 also.
03:38 Pause this tutorial and do this assignment.
03:41 Create two routes from Home to the School Campus


03:45 In the RouteMap drawing create each route on a separate layer, so that they can be printed

as two different maps each displaying only one route.

03:56 Let us now learn how to export the file as a PDF and also password protect our Draw file.
04:04 First let’s save the Draw file “RouteMap” as a PDF.
04:08 From the main menu, select File and click “Export as PDF”.
04:14 The PDF dialog box appears.
04:15 First, let us set the “General” options.
04:18 Click the “General” Tab.
04:20 Under “Range”, let us select “All” as we are converting all the pages in the Draw file to PDF.
04:28 Under “Images”, we shall select “JPEG compression”.
04:32 This is the most common format that is used for compression.
04:36 Next, click the Initial View tab.
04:39 We will keep the default values displayed in the dialog box.
04:44 Now, click on the Links tab.
04:46 We may have inserted links in the Draw file.
04:49 Again, let’s keep the default values set for Links.
04:53 Now, let’s assign a password to protect the PDF document.
04:58 To do so, click on the “Security” tab.
05:01 Click on the Set open password button.
05:04 The Set open password dialog box appears.
05:08 In the field “Password”, type any password with which you want to protect your file.
05:14 I will set my password as “Protect101”.
05:18 In the field “Confirm”, I will re-type my password “Protect101”.

Click OK.

05:25 Next, let’s set the permission password to print or modify the document.
05:31 Click on the Set permission password button.
05:35 In the field “Password”, type the password of your choice. I will type “ProtectAgain0”.
05:43 In the field “Confirm”, I will retype the password “ProtectAgain0”.

And click OK.

05:51 Notice that permissions for Printing and Changes are active now.
05:58 It is always a good practice
  • To set passwords
  • With a minimum of six characters
  • Including numbers and special characters.
06:08 Under “Printing”, select the option “Not Permitted”.
06:12 The PDF can be printed only if the correct password is provided, else it cannot be printed.
06:19 Under “Changes” select the option “Not Permitted”.
06:23 The PDF can be edited only if the correct password is provided, else it cannot be modified.
06:31 Now, let us click the “Export” button at the bottom.
06:35 The Export dialog box appears.
06:37 From the left panel, under Places, click on the location where you want to save your file.

I will choose Desktop.

06:47 Under File type, click PDF - Portable Document Format.
06:51 And click on the Save button.
06:55 The Draw file is converted to a PDF file and saved on the Desktop.
07:00 Let us switch to the Desktop now.
07:03 On the Desktop, double-click on the RouteMap PDF file.
07:08 The Enter password dialog box opens.
07:11 In the Password field, let's type the wrong password Protect111.
07:17 Click on the Unlock Document button
07:20 You will notice that the password field is cleared and we are prompted to enter the password once again.
07:29 In the Password field, let’s type the correct password Protect101.
07:35 Click on the Unlock Document button. The PDF file opens.
07:40 We have converted our Draw file into PDF and successfully password-protected it!
07:47 This brings us to the end of this tutorial.
07:50 Here we have learnt, the basics of layers.
07:53 How to convert a Draw file into a PDF
07:56 How to protect it using password encryption.
08:01 Here is an assignment for you.
08:04 Create another PDF of the RouteMap file.
08:06 In the PDF dialog box, change “Initial View” options
08:10 Observe what happens.
08:12 Check all the options for “User Interface”.
08:16 Set permission passwords.
