00:01 | Welcome to the Spoken Tutorial on LibreOffice Draw - Basics of Layers and Password Encryption PDF. |
00:09 | In this tutorial, you will learn the basics of layers. |
00:12 | You will also learn how to protect a Draw file using password encryption. |
00:18 | Export it as PDF. |
00:21 | 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. |
00:42 | There are three layers to every Draw file. |
00:44 | The Layout layer is displayed by default. |
00:48 | This is where we create most of our graphics. |
00:51 | The Control layer is used to store control elements such as buttons and forms. |
00:57 | The Dimensions layer is used to depict dimension lines or measurement lines for complex drawings. |
01:06 | For example, a drawing of a house must contain exact measurements of walls, positions of electrical wiring and so on. |
01:19 | Let’s print three maps that show the route from the 'House' to the 'School'. |
01:26 | Let’s call them Map 1, Map 2 and Map 3. |
01:31 | Map 1 shows all the landmarks in the area. |
01:35 | In Map 2, let’s show all the objects except the two 'Lakes', the 'Stadium' and the 'Commercial Complex'. |
01:43 | In Map 3, let’s show all the objects except the 'Park'. |
01:48 | Do we need to create three separate maps to show these? |
01:51 | No. Draw provides a solution to this with the help of Layers. |
01:58 | This way, there can be only one map file with many layers of information. |
02:03 | We can print or view a combination of layers using one Draw page. |
02:10 | Let us add some layers to the RouteMap. |
02:13 | Click on Layout layer. |
02:15 | Right-click and select Insert layer. |
02:18 | The Insert layer dialog-box appears. |
02:22 | In the “Name” field, type: “Layer four”. |
02:24 | You can add any title and description that is relevant to your drawing. |
02:30 | Check the boxes “Visible” and “Printable”. |
02:34 | Click OK to exit the dialog-box. |
02:37 | Click on Layout layer once again. |
02:40 | On the Draw page, select the map and ungroup it. |
02:44 | Now, let us select the Lakes. |
02:46 | Press the Shift key and select the Stadium and the Commercial complex. |
02:52 | Next, right-click and select Cut. |
02:55 | Then click on “Layer four” layer and paste them. |
02:59 | They are pasted in the same positions as in the Layout layer. |
03:04 | Click Layer Four once again. |
03:07 | Right-click to view the context menu and select Modify Layer. |
03:12 | The Modify Layer dialog-box appears. |
03:15 | Uncheck the box “Visible”. Click OK. |
03:18 | Objects in Layer Four are no longer visible. |
03:21 | The objects are present physically but are not visible. |
03:26 | Click Layout Layer. If the tab is not seen then press the left-arrow button till the Layout layer is visible. |
03:35 | We have our Map 2! In the same manner, we can create Map 3 also. |
03:42 | Pause this tutorial and do this assignment. |
03:45 | Create two routes from Home to the School Campus. |
03:49 | 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. |
04:01 | Let us now learn how to export the file as a PDF and also password protect our Draw file. |
04:10 | First, let’s save the Draw file “RouteMap” as a 'PDF'. |
04:14 | From the main menu, select File and click “Export as PDF”. |
04:19 | The PDF dialog-box appears. |
04:21 | First, let us set the “General” options. |
04:24 | Click the “General” Tab. |
04:26 | Under Range, let us select All as we are converting all the pages in the Draw file to 'PDF'. |
04:34 | Under Images, we shall select “JPEG compression”. |
04:38 | This is the most common format that is used for compression. |
04:42 | Now, click on the Initial View tab. |
04:45 | We will keep the default values displayed in the dialog-box. |
04:49 | Now, click on the Links tab. |
04:52 | We may have inserted links in the Draw file. |
04:55 | Again, let’s keep the default values set for Links. |
04:59 | Now, let’s assign a password to protect the 'PDF' document. |
05:03 | To do so, click on the “Security” tab. |
05:07 | Click on the Set open password button. |
05:10 | The Set open password dialog-box appears. |
05:14 | In the field “Password”, type any password with which you want to protect your file. |
05:20 | I will set my password as “Protect101”. |
05:24 | In the field Confirm, I will re-type my password- “Protect101”. Click OK. |
05:31 | Next, let’s set the permission password to print or modify the document. |
05:37 | Click on the Set permission password button. |
05:41 | In the field Password, type the password of your choice. I will type ProtectAgain0. |
05:49 | In the field Confirm, I will retype the password “ProtectAgain0” and click OK. |
05:57 | Notice that permissions for Printing and Changes are active now. |
06:03 | It is always a good practice to set passwords with a minimum of six characters, including numbers and special characters. |
06:14 | Under Printing, select the option Not Permitted. |
06:18 | The 'PDF' can be printed only if the correct password is provided, else it cannot be printed. |
06:25 | Under Changes, select the option Not Permitted. |
06:29 | The 'Password' can be edited only if the correct password is provided, else it cannot be modified. |
06:36 | Now, let us click the Export button at the bottom. |
06:41 | The Export dialog-box appears. |
06:43 | From the left panel, under Places, click on the location where you want to save your file. I will choose Desktop. |
06:53 | Under File type, click PDF - Portable Document Format. |
06:57 | And click on the Save button. |
07:01 | The Draw file is converted to a PDF file and saved on the Desktop. |
07:07 | Let us switch to the Desktop now. |
07:09 | On the Desktop, double-click on the RouteMap PDF file. |
07:14 | The Enter password dialog-box opens. |
07:17 | In the Password field, let's type the wrong password "Protect111". |
07:23 | Click on the Unlock Document button. |
07:26 | You will notice that the password' field is cleared and we are prompted to enter the password once again. |
07:35 | In the Password field, let’s type the correct password Protect101. |
07:40 | Click on the Unlock Document button. The PDF file opens. |
07:46 | We have converted our Draw file into PDF and successfully password-protected it! |
07:53 | This brings us to the end of this tutorial. |
07:57 | Here we have learnt: * the basics of layers. |
08:00 | * How to convert a Draw file into a PDF |
08:03 | * How to protect it using password encryption. |
