| 00.23 | Welcome to Meet The GIMP. |
| 00.25 | My name is Rolf steinort and I am recording this is Bremen, Northen Germany. |
| 00.31 | Today we'll talk about the Fuzzy Select Tool. |
| 00.36 | It is closely related to the select by colour tool. |
| 00.40 | But the fuzzy select tool selects only one contiguous region and the colour select tool selects all regions with similar colours. |
| 00.54 | There are some similar options like Replace, Add, Substract and Intersect with the current selection, and now I select Add. |
| 01.08 | Here you can see the same option, Antialiasing. |
| 01.13 | If we select antialiasing, border of the selection is not sharp and you get smooth corners. |
| 01.23 | And if it is not selected then you have a really sharp border between selected and unselected.
|
| 01.33 | The further options are Feather Edges and Select Transparent Areas. |
| 01.41 | Select Transparent Areas is useful while using mask sensor on perhaps. |
| 01.50 | Sample marge is the same as with the other and it selects all the visible layers. |
| 01.58 | If it is not selected then it works on current layer. |
| 02.04 | If you want to select something from the total output of image then select this option.
|
| 02.11 | Here is Threshold which defines how much difference between the colours is allowed to be in the selection or when something is out of selection. |
| 02.24 | It helps in selecting the pixels that have one definite colour. |
| 02.30 | The next important selection is , which mode do you want to have in the selection. |
| 02.37 | The composite mode is the gray value of added red, green and blue channels. |
| 02.44 | You can select the red, the green, the blue channel or the Hue, Saturation or the Value channel as the base for your selection.
|
| 02.56 | Now lets try Fuzzy Select Tool. |
| 03.01 | I just click into the image and the threshold is zero so lets see what happens. |
| 03.08 | I make a selection which is one pixel in size. |
| 03.13 | Now I increase the amount of Threshold to say 30 and click into the image and click on toggle quick mask here. |
| 03.28 | Now you can see the area which is selected. |
| 03.37 | I de-select the quick mask toggle, press tab to get the tool box and press Shift+Ctrl+A to unselect everything. |
| 03.49 | I can do this in a different way and for that I decrease the threshold to zero and click into the image and now I am drawing the mouse down and right. |
| 04.03 | When I increase the threshold, you can see that I am going into this blue area but I am still on the wall. |
| 04.13 | I think this tool is more useful for graphic designers and not for photographers.
|
| 04.22 | You can change the threshold by just pulling the mouse. |
| 04.26 | This works the same in colour selection tool. |
| 04.32 | I change Select by from Composite to Hue and click at the same point and draw to the bottom. |
| 04.43 | You can see that I have a way better selection of blue, green part of the wall, than I had before. |
| 04.54 | So choosing the right method of colour definition gives good result with this tool. |
| 05.05 | I click into the quick mask and here you see it’s nearly perfect, only some parts to repair and I would do that with painting in the quick mask and not with these selection tools.
|
| 05.25 | If you are confused about selecting the mode then you can see your image in different channels in the channel mode. |
| 05.41 | Select the blue channel and you see that everything has nearly the same blue value. |
| 05.50 | In the green channel there are some differences. |
| 05.55 | In the red channel it’s nearly the same here. |
| 05.59 | So I would select the green channel for selecting or in this case Hue channel.
|
| 06.10 | Selecting colour is the next tool here and it has the same function and same options here. |
| 06.19 | It has only one difference. |
| 06.22 | If you click here, you’ll select all fields with this colour and not one contiguous area. |
| 06.32 | The colour selection tool, selects all the areas with the similiar colour. |
| 06.41 | The name of the next tool is intelligent scissors or scissors selection tool. |
| 06.48 | This algorithm looks for edges and tries to follow them with the selection. |
| 06.56 | And I want to select here these letter boxes |
| 07.10 | So I Active the selection tool and I pull a point here and I get a plus sign near the cursor and I simply select the points.
|
| 07.42 | The algorithm is suppose to follow the borders and you can see here it didn’t took the otherway,it took the inside way.
|
| 07.56 | I zoom into the image and now I can draw this point upto here and there was a mistake with selecting this point. |
| 08.13 | So I pull these point up and you can see the algorithm follows the border if you give enough information where to follow. |
| 08.30 | It looks pretty good but I usually don’t use this because there are better ways to do this. |
| 08.44 | I think I would use the colour selection tool because it always takes the wrong way round. |
| 08.56 | So I finished with the selection. |
| 09.10 | I just click on the first point here and the cursor changes to plus. |
| 09.17 | Now put the next point and I have these 2 rings making a loop out of it. |
| 09.25 | I can still move the point around here and make the selection better. |
| 09.33 | So,when I now click into the selection 2nd time, the selction is selected. |
| 09.42 | And to look at the quality I activate the quick mask and zoom into it. |
| 09.57 | Now I look around in the selection. |
| 10.04 | Here is my fault, I should have clicked here. |
| 10.10 | So this is the fairly intelligent scissors. |
| 10.17 | The next and the last tool I want to cover today is the foreground selection tool. |
| 10.24 | It was quite sensation when the algorithm came out sometime ago and it was not so sensational in using in the GIMP. |
| 10.37 | But lets give it a try. |
| 10.41 | Here are the same modes and antialiasing isn’t activatable. |
| 10.48 | And here I want to select one single area and I want to select the statue. |
| 10.57 | So 1st I zoom into the image, to get a better control. |
| 11.06 | Now I select the selection tool and I can select contiguous region or different region but I select the contiguous region. |
| 11.21 | First I make a rough selection here with the automatic laser tool and now you can see that the area which is not selected is in blue colour. |
| 11.44 | I have selected a brush here and I can control the diameter of the brush with this slider and I paint through this stuff I want to have selected. |
| 11.59 | I have to see that I don’t select stuff which I don’t want to have in the image. |
| 12.17 | When I release the mouse button, the algorithm starts to work and some areas here has to be selected. |
| 12.27 | Everytime the selection gets updated and area that is similar to the stuff I just painted over gets selected. |
| 12.42 | Now I click on Mark Background and start painting the background that I don’t want to have in the image. |
| 12.54 | This tool works better when there’s more difference between the selected part and the stuff which is not selected and here the difference is not big enough. |
| 13.12 | Just press enter to accept the selection. |
| 13.17 | I think you have got an idea of how this tool works. |
| 13.27 | The path tool belongs also to this part but I’ll cover that sometimes else. |
| 13.36 | In the select menu there are some other stuff you can do with selections and i'll cover that also sometime else. |
| 13.48 | So this was it for this tutorial. |
| 13.52 | Let me hear some comments and I promise you for the next show with really new things which are viewer Generated content.
|
| 14.05 | You will find a link to this file in the show notes at meetthegimp.org and if you want to leave a comment then please do that. |
| 14.19 | This is Hemant Waidande dubbing for the Spoken Tutorial Project. |
