| Welcome to the Spoken Tutorial on '''“Layers and boolean operations” '''using '''Inkscape.'''

|-
| 00:07
| In this tutorial we will learn about Layers

|-
| 00:11
|Filters

|-
| 00:12
| Boolean operations

|-
| 00:15
| To record this tutorial, I am using

|-
| 00:18
| '''Ubuntu Linux''' 12.04 OS

|-
| 00:21
| '''Inkscape''' version 0.48.4

|-
| 00:25
| Let us open '''Inkscape'''. Go to '''Dash home '''and type '''Inkscape'''.

|-
| 00:30
| Click on the '''Inkscape '''logo.

|-
| 00:32
| Let's open the '''Assignment_2.svg '''file that we created earlier.

|-
| 00:38
|I had saved it in documents folder.

|-
| 00:41
| First, we will learn about '''Layers''' in '''Inkscape.'''

|-
| 00:45
| Go to '''Layer menu '''and click on '''Layers '''option'''.'''

|-
| 00:50
|Now the '''Layer palette''' is opened on the right side of the interface.

|-
| 00:55
| By default a '''layer''' is there. You can see, that is named as '''Layer 1'''.

|-
| 01:01
| To add or create a new '''layer''', click on the plus icon on the '''Layer palette'''.

|-
| 01:07
| A dialog box named '''Add layer '''opens up.

|-
| 01:10
| In the '''Layer name''' text box, we can assign a name to the '''layer'''.

|-
| 01:15
|I will name this layer as '''eye.'''

|-
| 01:18
| Now, we can decide the position of the '''layer''' by clicking on the '''Position''' drop down list.

|-
| 01:25
| There are 3 options here.

|-
| 01:27
|'''Above current''' will keep this layer on top of the current layer.

|-
| 01:32
|'''Below current''' will place this layer below the current layer.

|-
| 01:36
|'''As sublayer of current''' indicates that it will be a part of the current layer.

|-
| 01:41
| I will position it as '''Above current''' and click on the '''Add '''button.

|-
| 01:47
| Notice a new '''layer''' named '''eye''' is now visible in the '''Layer palette.'''

|-
| 01:52
| In a similar way, create another layer named '''bow.'''

|-
| 02:00
| Now we have 3 layers in the '''Layer palette.'''

|-
| 02:04
| Next let us learn to rename a '''layer.'''

|-
| 02:08
|First double click on '''Layer 1'''. And then rename it as '''circle '''and press '''Enter.'''

|-
|02:16
| Coming back to our '''canvas'''. There are 2 eyes and a bow.

|-
| 02:20
|Let us move these shapes to the 2 different layers that we created.

|-
| 02:25
| Select both the eyes by dragging the mouse.

|-
| 02:28
|Now press '''Ctrl + X''' on your keyboard. The eyes have now disappeared.

|-
| 02:34
|Now click on the '''eye layer''' in the '''Layer Palette. '''

|-
| 02:38
| Come back to the''' canvas '''and press '''Ctrl + Alt + V.'''

|-
| 02:44
| Repeat the same action for the bow shape.

|-
| 02:52
| Click on any empty space on the '''canvas''' to deselect all the objects.

|-
| 03:00
| The '''eye''' and '''lock''' icons help to hide and lock layers.

|-
| 03:04
| When you hide a layer, you are able to see the objects on the subsequent lower layers clearly.

|-
| 03:11
| When you lock a layer, you are able to prevent accidental edits to that particular layer.

|-
| 03:18
| These are particularly useful when we have to work on large and complex graphic assignments.

|-
| 03:25
| Notice 2 icons namely, an''' eye''' and a '''lock,''' on the left of each '''layer.'''

|-
| 03:32
|We will now learn how to use these.

|-
| 03:35
| To lock or unlock layers, click on the '''lock''' icon. I have now locked the '''bow layer.'''

|-
|03:42
| Note that if a '''layer''' is locked, we cannot make any changes to that '''layer'''.

|-
| 03:47
| Let's try to select the bow on the canvas. You will notice that it is not possible to do so.

|-
| 03:58
| Now, I will unlock the '''bow layer'''.

|-
| 04:01
| Now, I am able to select the '''bow''' object and change its properties, as well.

|-
|04:07
| To make a '''layer''' visible or invisible on the canvas, click on the '''eye '''icon to the left of the layer.

|-
| 04:15
| I am clicking on the '''eye '''icon for the '''bow layer.'''

|-
| 04:18
|Observe what happens on the canvas.

|-
| 04:23
| Now, let me duplicate the '''bow layer.'''

|-
| 04:26
| Go to '''Layer menu '''and click on '''Duplicate Current Layer '''option.

|-
| 04:32
| Notice a new layer named '''bow copy''' is created in the '''Layer Palette window'''.

|-
| 04:41
| But we cannot see the new '''bow '''on the canvas. That is because the '''bow object '''is overlapped on the previous layer.

|-
| 04:50
| Select the '''bow '''on the top '''layer '''and move it to one side to see both the '''bows'''.

|-
|04:56
| Select the '''circle layer.'''

|-
| 04:58
| Draw an '''ellipse''' on the '''canvas''' encircling the '''eyes''' and the '''bows'''. Color it orange.

|-
| 05:05
|The '''ellipse''' is seen in the background with the other objects visible above it.

|-
|05:10
| The four icons next to the '''plus''' icon in the '''Layers Palette''', helps to position the selected '''layer'''.

|-
| 05:17
| The first icon raises the selected '''layer''' to be the topmost '''layer'''.

|-
| 05:23
|The '''circle layer '''is currently selected.

|-
| 05:25
|Observe that on clicking, the '''circle layer''' now becomes the topmost '''layer.'''

|-
| 05:33
| The last icon lowers the selected '''layer '''to be the bottom-most '''layer.'''

|-
| 05:38
|Click on this icon. Observe that the '''circle layer '''is now the bottom-most '''layer.'''

|-
|05:44
| The second icon raises the selected '''layer,''' one '''layer''' above.

|-
| 05:48
|Click on this icon. The '''circle layer''' has moved above the '''eye layer.''' So the eyes are not visible.

|-
| 05:57
| The third icon lowers the selected '''layer,''' one '''layer''' below.

|-
| 06:01
|Click on this icon. Now the '''circle layer''' has moved below the '''eye layer.'''

|-
| 06:07
| So, that is how these four icons can be used.

|-
| 06:13
| The minus icon at the end will delete the selected '''layer'''. Select the '''bow copy layer''' and click on it.

|-
| 06:21
|Observe that the '''bow copy layer''' is no longer seen.

|-
| 06:27
| '''Blend mode''' is a shortcut to apply the '''Blend filter''' to an entire '''layer'''.

|-
| 06:31
|This means that if objects overlap on the selected '''layers''', '''Inkscape''' will do a pixel-by-pixel blend of the two objects.

|-
| 06:41
| So, keep the '''circle layer''' on the top to make the filters visible.

|-
| 06:46
| Click on the drop down list of '''Blend mode.''' Notice there are 5 options.

|-
| 06:52
| The first option that is '''Normal,''' does not add any filter to the layer.

|-
| 06:57
|Let me click on it. Observe no filter is added to the layer.

|-
| 07:03
| Next click on''' Multiply. '''

|-
| 07:06
|Notice''' '''that objects on the topmost layer, filters the light so that the objects on the bottom layers are visible.

|-
| 07:14
|At the same time, it also blends or mixes the colors to form darker colors in the overlap regions.

|-
| 07:21
| Next option is''' Screen.'''

|-
| 07:25
|Observe the top objects; they add lightness to the bottom objects.

|-
| 07:30
|So, it blends or mixes the colours to form lighter colours in the overlap regions.

|-
| 07:36
| Select '''Darken. '''The objects on the top layer, darken the objects on the bottom layers.

|-
| 07:44
| Now, let us select the last option that is''' Lighten. '''Here the top objects lighten the bottom objects.

|-
| 07:53
| If at any time you return the''' Blend mode''' back to''' Normal''', the blend filters applied so far, disappears.

|-
| 08:00
| We can see many more filters in the '''Filters menu. '''

|-
| 08:04
|To apply any particular filter, first select the object first and then click on the desired filter.

|-
| 08:12
| Move the '''circle layer''' to the bottom again.

|-
| 08:16
| Let me select an eye. Go to '''Filters menu.''' Select '''Blur''' and '''Fancy blur.'''

|-
| 08:26
|Observe the changes on the eye.

|-
|08:29
| Let me select the other eye. Go to Filters '''menu.''' Select '''Bevel''' and '''Smart jelly.'''

|-
| 08:39
|Once again observe the changes applied to the eye.

|-
| 08:44
| Now select the bow. Go to '''Filters menu.''' Select '''Scatter''' and '''Air spray'''

|-
| 08:51
|The bow appears as if it has been air-sprayed.

|-
| 08:55
| The '''Opacity''' option right below the '''Blend mode,''' helps to reduce the Opacity of the selected layer.

|-
| 09:01
| Select the '''circle layer.'''

|-
| 09:03
|Adjust the Opacity level and observe the change in the '''ellipse'''.

|-
| 09:10
| Next we will learn about '''boolean operations. '''

|-
| 09:13
| Go to '''Path menu.''' These are the available boolean operations.

|-
| 09:21
| Keep the available shapes aside.

|-
| 09:26
|Draw a square of green color and a circle of red color. Keep the circle above the square towards the side.

|-
| 09:36
| Select both. Go to Path menu and click on Union. Observe the 2 shapes are now joined together

|-
| 09:46
| Now press '''Ctrl + Z''' on your keyboard to undo this action.

|-
| 09:51
| Again select both. Go to '''Path menu.'''

|-
| 09:55
|Click on '''Difference '''and observe what happens.

|-
|09:59
| Press '''Ctrl + Z '''again to undo this action.

|-
| 10:03
| Again select both the objects. Go to '''Path menu''' and click on '''Intersection '''and observe the change in the shape.

|-
| 10:11
| Press '''Ctrl + Z '''again to undo this action.

|-
| 10:16
|Again select both objects. Go to '''Path menu '''and click on '''Exclusion.'''

|-
| 10:22
|Observe the change in the shape.

|-
| 10:24
| Again press '''Ctrl + Z.'''

|-
| 10:27
| Once again select both objects. Go to '''Path menu '''and click on '''Division.'''

|-
| 10:34
|Click on the divided circle and move that part aside to see the result.

|-
| 10:39
|Now press '''Ctrl + Z''' twice to undo these actions.

|-
|10:44
| Select both objects again. Go to '''Path''' '''menu '''and click on '''Cut path. '''

|-
| 10:50
|Observe the change in the shape.

|-
|10:53
|'''Cut path''' option works only if the object has stroke. Unselect the shapes first.

|-
| 10:59
|Now, select any one of the strokes and move it aside to make the cut path visible.

|-
| 11:05
| Let us summarize. In this tutorial, we learnt about

|-
| 11:09
| Layers

|-
| 11:10
| Filters and Boolean Operations

|-
|11:14
| Here are 4 assignments for you

|-
| 11:16
| Create a rectangle with pink color and a triangle with green color.

|-
| 11:21
| Keep the triangle on the top of the rectangle.

|-
| 11:24
| Select both. Use '''Union.''' It should look like a home icon.

|-
| 11:30
| Name the layer as '''home.'''

|-
| 11:32
| Draw a 2 circles.

|-
| 11:34
| Keep one on top of the other.

|-
| 11:36
| Select both and use Difference.

|-
| 11:39
|It should look like a crescent.

|-
| 11:42
|* Draw an ellipse.

|-
| 11:44
| Create a star with 10 corners.

|-
| 11:46
| Keep it in the centre of the ellipse.

|-
| 11:49
| Select both and apply '''Exclusion.'''

|-
| 11:52
| Create 2 layers named '''crescent''' and '''star''' respectively.

|-
| 11:57
|Cut the crescent shape and paste in crescent layer.

|-
| 12:00
| In a similar way do for the star shape.

|-
| 12:03
| Your completed assignment should look like this.
