Now, a free bitmap software available for Linex and Windows. The GIMP. Like Photoshop, it has plenty of features that allow us to undertake tasks as easy as changing a colour photograph to make a cool logo or an animation. The best way to understand how it works is to practice from the beginning. The fist time you open the program, two windows will appear on your screen, the principal window and the toolbox window. The fist one has a 10 item menu with options like Open file, filters, layer, etc.

The second one shows us some tools which are useful for manipulating images. As said before, the best way to learn, is to do it yourself. As Confucius said:

I hear and I forget. I see and I remember. I do and I understand.

 

Text over the image

Sometimes you need to add some text to a photograph or illustration. In such cases, we will need to paste a word  onto an  image.

 It is as easy as:

1. Download the image you want

2. Go to the tool box and select A ( marked in blue in the next image )

3.  Below the tool icons there is a Text menu where you may select the font, fontsize ... Choose the font and size you prefer and write a word.

 

 

 

 

 

 

 

 

 

 

That's all.  A  very simple exercise to begin with!

Using Gimp to make a  Button.

  Many websites incorporate a cool Web 2.0 button and it is time to try and do this ourselves, so, if you are ready, lets get down to business.

1st step, as usual, create a new image with 200 width and 100 Height and with a transparent background.

Step 2: Create a rectangle ( click on ) with the width and  height of the web 2 button we are going to generate.  To give the rectangle rounded edges  ->Select->Rounded Rectangle on the menu bar. The next image will show you the route

The window with the script  (a small piece of software which will run tasks in a program ) will allow you to change the radius. Choose  a  value between 40 and 60%.

Step 3: Click on the bucket and fill it with a bright colour like #3b8adc.

Step 4: Create a small rounded rectangle inside the big rectangle at the top. Repeat the methods  described before. Now you should have something like this

Step 5:  Go to the gradient tool and select the starting and finishing points  with the mouse. Have a look at the image again and you will see the two points for the gradient.

Now you have this:

Step 6:

 Add the text using the text tool( ). In font types you can choose whatever you want.

Step 7: Show the layer menu clicking Alt + L. Select the layer with the big rectangle and give it a shadow by going into Filter and clicking on ->Light and Shadow and then -> Drop Shadow ( see next figure )

Step 8: To see the full effect of the shadow, add a new layer with a white background. If you leave that layer on the top, you will just see a white image. Move it to the bottom of the layer stack using the layer menu. Just at the foot of the layer menu, two arrows will permit you to move the white layer down

That's it! This is the final image.

Layers:

When you see an image your impression is that what your seeing is just a piece of paper on which somebody has drawn something or that someone has taken a photo, but this is not exactly true. Sometimes there are two or more bonding images. These images are anchored to a layer. You can think of layers as a stack of slides or as the layers of clothes on your body. Each layer can be manipulated without affecting any other layer. This is very important, because if you don't like a" part of you image " you can rearrange it all very quickly ".Layers are stacked on top of each other and once you add a layer, the image window will tell you how many layer your image is comprised of ( see fig 5 ).

 

If you need to open a layer menu, just click on the Control key + L

 

 

Adding the 1^st  layer + 2^nd layer + 3^rd  layer + 4^th  layer ( with some transparency )  + 5^th layer  we have the image shown below. The “Layers” dialog ( which opens in a new window ) is the main interface to manage your layers and in it you can add a new layer, erase an old one, modify etc. The advantage of using layers is that you can construct an image and later modify it without affecting any other layer of the image.                  

                                       

 

 

Creating Badges using Gimp

1^st step: Open  a new image, 200x200 size and select a white background.

2^nd In order to make a 12 sided star, go to ->Filters->Render->Gfig

A new window will open and a tool menu will show you the properties to adjust. ( see fig below )

3^rd   Select the star tool   and increase the number of sides to 12.

4^th Step: Click 'Browse' and select a small brush, eg a 1 pixel brush.

 Now click  in the middle of the square and drag it to anywhere inside the image. A star will appear as you move the mouse.

5^th This is the Move Single Point tool. Click on that tool, go to the star and move the corner of the star ( a black point on the outside ) to create a star badge

6th Click on the "close botton" and the star should pop up in the previous window. Now, you have two layers in the Layer stack. ( see right )

7^th Step: Choose the 'Fuzzy select tool( ) and click  inside the star  and the star border should be selected.

Step 8: The gradient:. For that, choose two different colours. I have chosen two oranges. I used #f3d293 as the primary colour and #f9a70a as the secondary colour. Then set the -Shape- into the gradient tool as Radial. Click in the star to choose the starting point and the finishing point. You should get something like this.  

Step 9: The Shadow. The best way to select the full star is by clicking outside the star. In that case what we have selected is the outer area ( everything other than the star), so inverse the selection using ->Select->Invert' or (click Ctrl + I). Now we have selected just the star.

Step 10: Go to ->Select 'Script-Fu->Shadow->Drop-Shadow' and make sure that the values are set to: Offset X : 8 , Offset Y : 8 , Blur Radius : 4 . Try with other values if you want to play with it. Then click OK. Now you should have this..

Step 11:  Select the text tool and  write whatever you want. First fit the text area inside the star. This is what I had in the end.

Yellow beetle

An easy first layering exercise is to place an object in the background. In this exercise, we are going to surf the internet, choose a car, get rid of its background and then place the image over a sea background.

The yellow beetle is an easily workable image. Go to the magic and select the yellow background. Then start to rub it out. Carry on with all zone until you get to the yellow car. Use the eraser if needed. ( see yellow car 2 )

 

 

 

 

 

 

And now, a large and wide blue see background:

Simple Animations with Gimp

What happens if layers do not appear at the same time. Images in layer 1 appear at Time 1, and layer 2 at time 2 and so on. Do you remember what Walt Disney did to make Mickey Mouse move? Now, you'll learn how to use layers to make a dynamic image or gif. Using GIMP as an animation software requires you to think of every layer of the image as an animation frame. It is important that layers can be both replaced or combined, so there are two options. You will want to stage each frame separately. 1st As one frame per layer (replaced) and 2nd Cumulative layer ( Combined) In the first case, each layer disappears as the next layer appears and in the second case, all the layers stay on the screen at the same time. Let's move the beetle car along the sea!!!!! 1st Step. Take a sea background and paste the car on top. Save as frame1.jpg. Repeat for frame2.jpg but the car, should be placed a little further to the left. Carry on until you get about 12 or 14 images of a car on the sea, each one a little further to the left. Now, let's make our "Disney book". 2nd Step: Open the first image. Then Go to File --Open as Layer-- Choose layer2.jpg 3rd Now you have two layers in your exercise. Check by clicking Alt+L. 4th Step: Do Step 2 as many times as images you have saved 5th Step: Go to File--Save as --car-on-sea.gif. It is very important that the file is saved as GIF because gif files allow animation while jpg files don't. 6th The next window will show some gif animation options. If you select loop forever, the animations won't stop. The Delay between frames is the time between one frame and the next and the frame disposal is the way the frames will be shown. Once it is done, open a browser and select your work.

Make a banner with a logo and some text. It should be like the following banner

Exercises:

Give a Show to a Flower.

Download a nice flower or use this one. To download, click on the right mouse button. In this exercise we are going to use The Magic Wand, a very attractive tool situated in the first row, it's the fourth tool. The magic wand selects areas by grouping pixels that are similar in colour and that are are spatially connected in some way . Click on the image and select the area to remove. If you want to eliminate the green zone, once you have selected the area, push Ctrl + X keyboard keys. Depending of your skill the next image would be, more or less, like this:  

 It's easy once you've got the hang of it. Now, let's go to another interesting tool. The eraser  tool, represented by a rubber.  A trick, in order to get a clear image, is to use the zoom tool   or push the + key in the keyboard.

 

 

 

Satisfied?

Go ahead and try with another one.

Here , a daisy in which we have applied all processes we applied before, but in this case, with a transparent background . It is important to note that cutting produces a transparent background ( gray squares ) only if the original image layer has an alpha channel.

Before we do anything else, let's apply a filter, in this case, Route: Image: Filters/Blur. Now the image is cleaner. Now it is time to create the shadow. Choose the Bucket Fill tool and select the black colour. Fill up the daisy with "black paint " and you will have something like this: After this, The blurring can be performed as before, but the route changes. See figure 5 where it is shown.  

A Gaussian Blur ( type IIR) is used with following values: radius of 20, Offset x = 15 and offset y = 15. Colour black and opacity 100%. You should have a window and an image similar to the following:  

Fig 5

All that remains is to place the  shadow and  the flower ( two layers )   over an appropriate background ( third layer ). Choose whatever you want as a background but a solid colour would be perfect. 

 

Creating Reflections for Logos

Step1: Open a new image 440x320 and from the Tools Dialog select the Text Tool. Then choose your font and letter size. This is our fist layer that should be renamed "text". Step 2: There are many gradients on the gradients tools, but we are going to use a new web 2 grey blue. Probably your Gimp Version does not have that gradient, so download it here . To install, unzip and place all files into \.gimp-2.2\gradients. Step 3: Now that we have the Gradient colour, in gradient tools, select Screen in Mode and the Shape as Linear. Have a look at the following image. Place the mouse below the text and drag from the bottom to the top. You should have something like this...

Step 4: Making an outline. It's easy, it just takes a while to figure out. Go ahead and select the "main text" layer and then, as shown in the next image, select "Alpha to selection".

Step 5: Go to Select->Grow to access the "Grow Selection menu". Set it to a 3px. Step 6: After doing the step 5, you can see that the outline has got a bit wider. The next thing is to create a new layer, with a transparent background, and the shape of the grow outline which will be filled up with an appropriate colour. Go to Layer->Create new Layer and Name it Border2. Fill it with 6291c0 colour using the Bucket Fill Tool. It should look like this:

Step 7: A reflection is a copy of an image that is paler and less defined. Duplicate the Main Text layer and the border2 layer. After that, merge both. First move both onto the top of the layer stack and click on Layer layer-> Merge down, to merge them down. Rename the new merged layer as Reflection. Step 8: Click on Ctrl + L to see the layer menu. Click on the eye to select the reflection layer and De-select any other layer. Make sure the Flip tool () is on vertical mode. Then drag upwards to finally flip it. Step 9:In the new layer, select the Gradient Tool in Blend mode ( Screen ). Apply it to the reflection layer from bottom to top, or from top to bottom depending on the gradient set. Mix all layers.   

Here is the final result

Sun Rise Header Graphic

This tutorial  will allow you to create a  nice sun rise vista. First off all download the last version of GIMP and  two types of brushes. To download click on  floral brushes  and grass brushes.

After downloading them unzip and place them in GIMP-2.0\share\gimp\2.0\brushes or whatever you have installed your last version of GIMP. Everything ok? Are you ready? Then let's get down to business.

Step 1: Create a new image. You are free to make it whatever size you want, depending on what you have in mind. For example enter a 620x220px for a header or footer banner. Step 2: We are going to start with a transparent background. First create a new layer and from the toolbox select the Gradient blend tool. (Blend-> mode screen ). Go to your colour box and enter ffc662 for the background colour and ff6c00 as your foreground colour. Step 3: Apply it so that the dark orange (ffc662 ) starts from the top and the light orange (ff6c00 ) is at the bottom. The next image will show you what it should look like.

Step 4: Go to Layer->Create a new layer with transparent background and use the ellipse tool to draw an oval shape. The axel of the oval must be at the bottom of the canvas. Leave some distance at the top, right and left. Then go to Select->feather and set it to 100px. Finally, choose a yellow colour (eg # fffe96 ) for the foreground and fill the selection in using the paint bucket.

 

 

 

 

Step 5: Do step 4 again but this time draw a circle. Then go to Select->feather and set it to 50px. Now, instead of filling it in with yellow colour, fill the bucket up with white paint and spill it into the selection area. Above this paragraph, on the left you will see steps 4 and 5 illustrated. Step 6: In the Stack layer, select just the last layer and select the brush tool ( situated in the toolbox ). Then select "Circle Fuzzy (17)" and scale the size to around 6.78. Step 7: Apply a few strokes to the bottom of the layer. It is going to be the ground for the grass. It should be just a few pixels wide. Have a look at the next image.  

 

Step 8: Time to grow grass. If you click on brush ( paintbrush tool ) you will see the new brushes we installed at the start. There are three types of grass and some plants. Play with them and add them to the ground. For the grass, set the scale size to 0.19 and tick the random box. This menu will only open if you click on Brush Dynamic. Once our bottom is filled with small grass we can go ahead and add a new grass type. Select larger grass and randomly mix with the other grass brushes. Step 10:In the final step, we'll add the floral vines brushes to our scene, at the right and at the left. Change the Scale to a value that fits your scene, about 5 or 6. Step 11: If you want to add some text, go to layer-> add new layer and write whatever you want. Select all the layers and you should have something like this:  

Adding life to your favourite  Photograph

 A picture is worth a thousand words  is a old proverb and it is true. So if the image is a superb image, we could say:  a picture is worth 5 thousand words.

In this tutorial we are going to enhance  a photo.  Fist of all, download the photo and a nice wallpaper as shown below.

 

 

 

 

 

 

 

 

Step 1: Using the Fuzzy select tool ( ) select the area you want to eliminate. In this case, the blue sky. Just select and eliminate as many closed areas as appear in the photos. Use the eraser and a 1 pixel  brusher to erase small defects. You should have something like this:

 

Step 2: Observe that after eliminating the blue sky, the background is white. We want a transparent background, but  first it needs a touch of colour, so go  to Colours->Auto->Colour Enhance. Then use again the fuzzy select tool and click in the white are. Then go to Select->Invert and later,  Key Control + X . Now we have the photo in the clipboard

Step 3: Open a new layer with transparent background and the same size as the old photo. Move the image downwards.

Step 4: Go to ->File->Open as layer and pick the wallpaper. It should be opened sized already to the size of our layer, so if you didn't do it before, please resize the wallpaper image. Now we have to layer. Move up the first one and leave the wallpaper down in the stack layer. That's it, here is our beach photo:

Dictionary::

Blur  :  making confused in form or outline; make indistinct: example The fog blurred the outline of the bus.

 Enhance: to raise to a higher degree,  intensify and  magnify.
