Time	Narration
00:00	Inkscape. માં “ Layers and boolean operations” પરના સ્પોકન ટ્યુટોરીયલમાં તમારું સ્વાગત છે.
00:07	આ ટ્યુટોરીયલમાં આપણે શીખીશું લેયર્સ
00:11	ફિલ્ટરસ
00:12	બુલિયન ઓપરેશનસ
00:15	આ ટ્યુટોરીયલ રિકોર્ડ કરવા માટે, હું ઉપયોગ કરી રહી છું.
00:18	Ubuntu Linux 12.04 OS
00:21	Inkscape આવૃત્તિ 0.48.4
00:25	ચાલો Inkscape.ખોલીએ Dash home પર જાઓ અને ટાઈપ કરો Inkscape.
00:30	Inkscape લોગો પર ક્લિક કરો.
00:32	ચાલો પહેલાથી બનાવેલ Assignment_2.svg ફાઈલ ખોલીએ.
00:38	જે મેં ડોક્યુમેન્ટ ફોલ્ડરમાં બનાવેલી છે.
00:41	પ્રથમ આપણે ઇન્સ્કેપમાં લેયર્સ વિષે શીખીશું.
00:45	Layer menu પર જાઓ અને Layers option. પર ક્લિક કરો.
00:50	હવે ઇન્ટરફેસની જમણી બાજુએ Layer palette ખુલ્યું છે.
00:55	મૂળભૂત રીતે layer ત્યાં છે તમે તે Layer 1 નામે જોઈ શકો છો.
01:01	નવું લેયર ઉમેરવા કે બનાવવા માટે તમે Layer palette પર વત્તા ચિન્હ પર ક્લિક કરો.
01:07	ડાઈલોગ બોક્સ Add layer ખુલે છે.
01:10	In the Layer nameટેક્સ્ટ બોક્સમાં આપણે લેયરને નામ અસાઇન કરી શકીએ છીએ.
01:15	હું આ લેયરને eye. નામ આપીશ.
01:18	હવે આપણે Position ડ્રોપડાઉન પર ક્લિક કરીને આપણે લેયરનું પોજીશન નક્કી કરી શકીએ છીએ.
01:25	અહી ત્રણ વિકલ્પો છે.
01:27	Above current એ વર્તમાન લેયર ના ઉપર આ લેયર મુકે છે.
01:32	Below currentએ વર્તમાન લેયર ના નીચે આ લેયર મુકે છે.
01:36	As sublayer of current એ આ જ લેયરનો એક ભાગ બને છે.
01:41	Above current તરીકે તેને પોજીશન આપીશ અને Add બટન પર ક્લિક કરો.
01:47	નોંધ લો કે eye નામક લેયર હવે Layer palette. માં દેખાય છે.
01:52	તેજ રીતે બીજું bow. નામનું એક લેયર બનાવીએ.
02:00	હવે Layer palette. માં આપણી પાસે ત્રણ લેયરો છે.
02:04	આગળ ચાલો આપણે layer. નું નામ બદલીએ.
02:08	પ્રથમ ચાલો Layer 1 ડબલ ક્લિક કરીએ. અને પછી તેને circle નામ આપીને Enter. દબાઓ.
02:16	canvas. ચાલો આપણા કેનવાસ પર પાછા આવીએ અહી અહી બે 2 eyes અને bow બે લેયર છે.
02:20	ચાલો આ આકારને બે વિભિન્ન લેયરસમાં મુવ કરીએ જે આપણે બનાવી છે.
02:25	માઉસને ડ્રેગ કરીને બન્ને આંખોને પસંદ કરો.
02:28	તમારા કીબોર્ડ પર Ctrl + X દબાઓ. હવે આંખો અદ્રશ્ય થઇ ગયી છે.
02:34	Layer Palette. માં હવે eye layer' પર ક્લિક કરો.
02:38	canvas and press કેનવાસ પર પાછા આવો અને Ctrl + Alt + V. દબાવો.
02:44	bow શેપ માટે હવે તેવીજ પ્રક્રિયા દોહરાવો.
02:52	બધા ઓબ્જેક્ટને નાપસંદ કરવા માટે કેનવાસ પર કોઈ પણ ખાલી જગ્યાએ ક્લિક કરો.
03:00	eye અને lock આઇકન લેયરને સંતાડવા અને લોક કરવા માટે મદદગાર છે.
03:04	When you hide a layer, you are able to see the objects on the subsequent lower layers clearly.જયારે તમે લેયરને હાઈડ કરો છો તમે ઓબ્જેક્ટને અનુગામી લેયર પર
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.
