00:00 | Welcome to the Spoken Tutorial on Fill color and stroke using Inkscape. |
00:06 | In this tutorial, we will learn about:
Fill color in objects Give objects an outline Various types of gradients and Stroke paint and style. |
00:20 | For this tutorial, I am using:
Ubuntu Linux 12.04 OS Inkscape version 0.48.4 |
00:29 | Let's open Inkscape. For this, go to Dash home and type: "Inkscape". |
00:35 | You can open Inkscape by clicking on the logo. |
00:40 | Let's open the 'Assignment.svg' file that we created earlier. I had saved it in my Documents folder. |
00:50 | These are the 3 shapes we created in an earlier assignment. |
00:54 | Recall that we had learnt to change color using the color palette at the bottom of the interface. |
01:01 | Now we will learn how to fill colors of various types using Fill and Stroke. |
01:08 | Let's go to Object menu and click on the Fill and Stroke option from the drop-down list. |
01:13 | Notice that the Fill and Stroke dialog box has opened on the right side of the interface. |
01:20 | There are 3 tabs in this dialog box: Fill, Stroke paint and Stroke style. |
01:27 | Now, we will click on the rectangle in the canvas area. Observe that the options and icons in the Fill and stroke dialog box get enabled. |
01:38 | First, we will learn about the Fill tab. |
01:41 | Notice there are 6 icons under the Fill tab. Let us learn what these icons do. |
01:48 | The first icon is called No paint. It indicates that the object will not be filled with any color. |
01:56 | Click on the icon and notice the change in the rectangle. The color of the rectangle has been removed. |
02:03 | The next icon is Flat color. It helps to fill a solid color into an object. |
02:11 | Click on the Flat color icon and observe the change of colour in the rectangle shape. |
02:17 | Under Flat color, notice that there are 5 sub-tabs. |
02:21 | By default, RGB tab is selected. |
02:25 | Under 'RGB' tab, there are 4 sliders. |
02:29 | The first 3 sliders indicate the intensity of Red, Green and Blue colours. |
02:36 | We can change the color by moving these sliders in left or right directions. Observe the color change in the rectangle as I do so. |
02:46 | The fourth slider is the Alpha slider. With this, we can increase or decrease the opacity level of the colour, from opaque to fully transparent. |
02:57 | As I move these 4 sliders, observe that the RGBA values of the color shown in these boxes change automatically. |
03:06 | Let me move the sliders once again so that you can observe this change. |
03:12 | We can change the color manually by changing the values of each color in the boxes at the right of the sliders. |
03:20 | Let me change the value of Red to 100, Green to 50 and Blue to 150. Notice the color of the rectangle has now changed to violet. |
03:32 | I keep the Alpha level as 255 since I do not want to reduce the opacity level. |
03:40 | The next tab is HSL and it stands for Hue, Saturation and Lightness respectively. |
03:49 | We can use the Hue slider to get a base color. I move the slider towards the left direction to get a base of green color. |
03:59 | We can adjust the saturation of the base colour using the Saturation slider. |
04:04 | Observe the change in the saturation level by moving the slider in left or right directions. |
04:12 | The Lightness slider adjusts the 'lightness' of the base color. |
04:16 | With this option, one can vary the shade of the base colour from pure white to pure black or any shade in-between. |
04:26 | As before, the Alpha slider is used to increase or decrease the opacity level from opaque to fully transparent. |
04:35 | The next tab is CMYK which denotes Cyan, Magenta, Yellow and Black respectively. |
04:44 | By moving these sliders, we can increase or decrease the intensity or the depth of the base colour. |
04:52 | This color mixing option is useful when design projects are to be printed on commercial presses. |
05:00 | Next is the Wheel tab. This is an alternative representation of the HSL color mixer. |
05:07 | We can select the base hue by clicking on the color ring that is based on the standard color wheel. |
05:14 | So, I will click on yellow shade to select a base of yellow color. |
05:19 | Within the color circle, there is a triangle with a small circle inside it. Just click on it and drag it inside the triangle and observe the color change in the rectangle. |
05:31 | The CMS tab will only be of real interest to those working in color managed environments. |
05:38 | For now, we will skip this tab. |
05:43 | Next, let us learn how to create a Linear gradient. |
05:47 | Go to canvas and click on the circle. |
05:50 | Now, come back to the Fill and Stroke dialog box and click on the Linear gradient icon. |
05:57 | Observe the gradient fill in the circle. |
06:00 | The gradient will be given a name ending with a series of random numbers. |
06:05 | In my interface, the number is linearGradient3794. In yours, it may be different. |
06:14 | We can change the gradient by clicking the Edit button which is right below the linear gradient number button. |
06:21 | This will open the Gradient editor dialog box. |
06:26 | The top button in this box is named stop followed by some random numbers and it contains a drop-down menu. |
06:34 | If you click the arrows on this drop down, you will see two stop options. |
06:39 | The first one denotes the pure base colour. The other one is half checker board, indicating that it's transparent. |
06:48 | Select the second option, that is, the transparent stop option. |
06:53 | Go to the Stop Color below. Change the RGB values to whichever color you like by moving the sliders. |
07:00 | Keep Alpha value at 255 to make the gradient fully visible. Close the Gradient editor dialog box. |
07:09 | Now, we can change the gradient angle. To do so, click on Node tool from the tool box, on the left of the interface. This is located right below the Selector tool. |
07:21 | This will display a line on the circle. This line represents the gradient. |
07:29 | These currently overlap with the square handle and the arc handles of the circle. |
07:33 | We will have to move the gradient line handles a little bit, so that we can see the handles clearly. |
07:40 | Click and drag the circular handle or the square handle to change the position where the gradient starts and ends. |
07:50 | We can also rotate the direction of the gradient by moving the circular handle, as demonstrated. |
07:58 | Now, we will learn how to use Radial gradient. Click on the icon and observe the gradient change in the circle. |
08:06 | The Radial gradient is formed in a circular shape. |
08:10 | Notice 1 square handle and 2 circular handles. |
08:15 | Click on the middle square handle to move the gradient's starting point. I will move it to the bottom left. |
08:22 | Click and drag on any one of the circular handles to make changes in the gradient. |
08:28 | Observe the change in the height and width of the gradient shape. |
08:37 | We can find the Gradient tool in the Tool box also. |
08:42 | Let's click on it and come back to our circle. |
08:45 | Notice that the cursor has now changed into a plus sign with capital I. |
08:51 | Now, click anywhere inside the circle and drag. Notice the change in the gradient. |
09:00 | Now, click anywhere outside the circle and drag. |
09:04 | Notice the change in the gradient. |
09:06 | Next, we will learn how to overlay various patterns on shapes. |
09:11 | Go to Tool box, click on the Selector tool and then click on the star shape. |
09:17 | In the Fill and stroke dialog box, click on the Pattern icon. Notice the color of the star has changed to a stripe pattern. |
09:26 | There is a drop-down menu under Pattern fill. Click on the arrows to see the available patterns. |
09:32 | Let's click on Checkerboard and observe the change in the star shape. You can use any of these available patterns shown here. |
09:44 | We will learn about Swatch in another tutorial. |
09:48 | The last icon called Unset paint, is used to unset the color of the selected object to black. |
09:54 | Click on the icon and observe the color change in the star. It has changed to black. |
10:01 | Now, let us learn how to give stroke or an outline to an object. To do this, we have to use the Stroke paint tab. |
10:09 | Now, click on Stroke paint tab and click on the rectangle. |
10:14 | The icons under the Stroke paint tab are the same as the Fill tab. |
10:19 | They function in the same manner as well. |
10:22 | With the first icon, that is No paint, we remove the outline of the shape. |
10:26 | Next, we will click on Flat color icon. We see a black color outline around the rectangle shape. |
10:33 | We can increase or decrease the thickness of the outline using the Stroke style tab. |
10:44 | Let's keep the width parameter as 10. We can also change the units into percentage, point etc. depending on our requirement. |
10:54 | I will keep the unit as Pixels. |
10:56 | Let's go back again to the Stroke paint tab. We can change the color of the stroke by moving the sliders under the RGB tab. |
11:04 | Observe the color change in the outline, as I do so. |
11:09 | Explore the other Flat color options such as HSL, CMYK, Wheel and CMS on your own. |
11:17 | Now, let me click on the Linear gradient. This gives a gradient outline to the rectangle shape. |
11:24 | The gradients that we used earlier, will appear in the drop-down list here. We can use any of those too. |
11:32 | Let me give red and blue gradient outline to my rectangle. |
11:38 | In a similar way, we can use the remaining stroke icons and give some interesting patterns and gradient outlines to our objects. |
11:46 | Next we will learn about Stroke style. Click on it. |
11:50 | We already learnt how to modify the width of the stroke. |
11:54 | Now, let's look at the 3 Join icons namely, Miter join, Round join and Bevel join. By default, the stroke is in Miter join. |
12:08 | Let me zoom in to one of the corners of the rectangle for a better view. |
12:12 | Now, let's click on the Round join to give a round corner to the stroke. Observe the changes in the edges of the stroke. |
12:21 | Next, we will click on the Bevel join option to create a Bevel corner. |
12:26 | Various dash patterns are available in the Dashes drop-down menu. Using these, we can give different dash patterns to the stroke and vary the width too. |
12:38 | Next is the Cap option. This basically works on line strokes. |
12:44 | Go to Tool box. Click on Freehand tool. So, let us draw a line with the help of Freehand tool. |
12:50 | Now, let us zoom in to the end of the line. |
12:54 | By default, Butt cap is selected and it gives a flat edge to the end. |
12:59 | Now, I will click on the Round cap to give a rounded edge. |
13:04 | Next is the Square cap which gives a flat and extended edge to the ends of the line. |
13:13 | There are 3 Markers right below the Dashes tab which places markers on the middle of the path. |
13:20 | Click on the drop-down menu of each Marker to see the available lists. |
13:25 | Under Start Markers, let me select Torso. |
13:29 | We will select Curvein as Mid markers. |
13:33 | For the End Markers, we will select Legs. |
13:39 | Observe a cartoon shape is formed on the canvas. |
13:44 | Lastly, notice 2 sliders at the bottom of the Fill and stroke dialog box, namely, Blur and Opacity. |
13:53 | Let's first select the rectangle again. |
13:56 | The Blur slider is used to give a blur effect to an object. I will click on the slider and move it towards the right. |
14:04 | Observe that the rectangle becomes blurred as I move the slider more and more to the right. |
14:15 | The Opacity slider is used to give transparency to a shape. Move the slider to the right and observe the changes in the shape. |
14:27 | Let us summarize. In this tutorial, we learnt to: |
14:31 | Fill color in objects using the Fill and Stroke options
