Keyboard Shortcuts

• Main Image Window• Edit• Keyboard Shots– Learning these shortcuts

will save time when you are working on your graphics' projects.

– Here a list of some of the shortcuts keys


Getting to Know GIMP

• A Tour of the most Important GIMP Windows– The Toolbox– Menu Overview– Customize Settings

Menu Overview

• Menu• Submenu• Double click to detach• I have double clickedText Tool to display theSubmenu separately from the main Toolbox menu


Toolbox

• Tool title• Toolbox Buttons• Foreground Swatch• Background Swatch


Tool, Image Window, Layers

• Docking• Dialog• Layers Dialog


The Layers Dialog Box

• GIMP has a lot of useful dialogs.

• You can see the whole list from– File-Dialogs in the Toolbox

menu or the image window’s top-level Dialogs menu

• Each separate dialog window is called a dock, and can hold many additional dialogs inside it.


Opening Files

• File Open• Location


A First GIMP Project-1

• Open light_saber.jpg• Open luke_at_home.jpg• Copy light_saber.gif and

paste into luke_at_home.jpg

• Use the move tool to reposition any place you would like on file one.

Questions?

• Do we have any questions at this point?• Next skill improving digital photos


Improving Digital Photos

• Opening files• Scaling files• Saving files• Cropping files• Brightening and

Darkening files• Rotating files• Sharpening files• Fixing Red-eye files


Scaling Images

• Open luke_at_home>Image >Scale Image

• Chains links• Aspect Ratio• Resolution


Four ways of Saving

• Save• Save As• Save as Copy• Save Template


Save

• The Save command saves your image to disk. If you have already saved the image, the previous image file is overwritten with the current version.


Save As

• The Save as command displays the “Save Image” dialog. Gives you a text box to assign a name to the file, and a drop-down list a directory to save it in. Select File Type option expander to pick a different file type.


Save As Copy

• Save a Copy command does the same thing as the Save command, but with one important difference. It always asks for a file name and saves the image into the specified file, but it does not change the name of the active image or mark it as “clean”.


Saving as Template• The Save as Template

command creates a template with the same dimensions and color space as the current image. A dialog pops up, which asks you to name the new template, then the template is saved and becomes available in the New Image dialog. If you give a name that already exists, GIMP generates a unique name by appending a number to it.


Cropping

• Open the biplane image from our GIMP Folder

• Cropping is used to remove any unwanted selection from a digital photo we do not need for a current graphic project.

• So let us take a look at the cropping tool and then remove the unwanted part.


After Cropping

• Here is the same photo after we have cropped it.

• Save as– Biplane_cropped


Brightening and Darkening

• A common problem with camera images is that they are either too light or too dark.

• GIMP has many powerful tools that can be used to correct these problems. Here a few tools we can use.– Color Balance – Brightness and Contrast– Levels– Curves


Rotating

• GIMP offers a rotation tool that can correct minor errors made while shooting with your camera.


Sharpening

• GIMP can sharpen photos, but can’t work miracles.

• The two most important ones are:– Sharpen– UnSharp Mask


Fixing Red-Eye

• Open Ethan image• Red-eye occurs when

there is too much light from the flash on your camera. Turning the pupils into diabolical crimson.

• GIMP has a red-eye filter built in to correct these problem.– Filters, Enhance, Red-Eye

Removal


Questions?

• Do we have any questions at this point?• Next skill introduction to layers


Introduction to Layers• Every image in GIMP is made by

combining one or more separate images, called layers, laid on top of each other.

• Using Layers to add text• Using the Move Tool• Changing colors: GIMP’s color

chooser• Simple effects using layers• Linking layers together• Performing operations on layer• Using layers for copy and paste• Aligning layers

• Tour of Layers dialog box

• Making simple GIF animations using layers


Introduction to Layers

• What is a Layer?• Layers to Add Text– The Text Tool

• Using the Move Tool• Changing Colors– Color Chooser

• Simple Effects– Drop Shadows


What is a Layer?

• Every layer has a name. This is assigned automatically when the layer is created, but you can change it.

• You can change the name of a layer either by double-clicking on it in the Layers dialog, or by right-clicking and then selecting the top entry in the menu that appears, Edit Layer Attributes


Creating a New Layer

• Layer


A Tour of Layers Dialog

• Title Area• Tabs• Layer Mode• Opacity• Keep Transparent• Layer List• Layer Buttons


Layers Continue

• Linking Layers together• Performing operations on Layers• Using Layers for Copy and Paste– Select Only the Part You Want to Paste– Paste into the Image– Scale the Pasted Layer– Aligning Layers


The Text Tool• Double click the A in Toolbox

Window

• This will open the Text Tool– Font– Size– Colors– Justify– Indent– Line Spacing– Letter Spacing


Move Tool

• From the Toolbox select the four head arrow.

• Select the object you would like to move in the image window .

• Then move the object to the new location.


Change the Foreground

• Click on the Foreground Tool in the Toolbox Window and then chose color


Change the Background Color

• Click on the background tool in the Toolbox Window and then chose color


Simple Effects Using Layers

• From the Main Image Window you select Filters

• Select Submenus and apply


Questions?

• Do we have any questions at this point?• Next skill how to create Drawings in GIMP.


Drawing

• Make a new image• Using layers for drawing• Drawing lines and curves• Changing colors and

brushes• Outlining and filling

regions• Filling with patterns and

gradients• When GIMP won’t draw


Using new Layers Drawing

• A New Image• Layers for Drawings• Drawing Lines and

Curves• Hard-Edged Lines• Drawing Tools Options• Airbrush Top• Ink Pen Tool• Easer Tool


Drawing Rectangles, Circles, and other Shapes

• Defining Regions• Outlining Selections:

Stroking• Free Select with the Lasso• Filling Regions• The Bucket Fill Tool• Gradients: The Blend Tool• Patterns are under Layers

drag and drop


Change Colors and Brushes

• Main Image Window• Layers• Brushes


Erasing

• The Eraser, like other drawing tools, uses the current brush and color to erase with, so make sure you select the correct brush and color before you begin erasing.


Stroking Regions

• GIMP doesn’t have any tools specifically for drawing shapes, which confuses some people coming from other drawing programs.

• The trick is to make a selection and then stroke.

• Edit, Stroke Selection, on the next dialog box chose the stroke you want to work with.


Filling with Patterns• Filling a selection with solid

color or pattern is easy.• First chose you drawing tool

and make a new drawing or select a object in the main image window.

• Make sure to select from the Toolbox, Layers Tool

• Edit– Fill with FG Color– Fill with BF Color– Fill with Pattern


Filling with Gradients• The Gradient Chooser is located

on the Toolbox, below the current brush and pattern.

• Choose your gradient and select the Blend Tool from Toolbox

• Next apply your gradient by using the Blend on your image

• Most of the gradient available in the dialog box have fixed colors regardless of the current foreground and background.

• Some gradients also include transparency, or partial transparency.


When GIMP Won’t Draw• GIMP will only draw to the

current layer.• It’s also possible you have

pasted recently and still have a floating selection.

• While looking at the Layers Dialog, take a look at the Keep Transparency button. If that is checked GIMP won’t let you draw

• Check the opacity tool in the tool options: make sure it’s at 100%.

• Layers each have mode, and some modes do strange things in combination with the layer beneath. Make sure that the current layer’s mode is Normal unless you are creating a effect.

• Check the Mode in the tool options for the drawing tool you're using. If it’s not Normal, unexpected things can happen.


A Drawing Project-2• Most drawing projects begin with a

blank canvas in the new image window.

• To practice drawing techniques, we will use new layer 200x400 pixels that will easily fit on our computer screen– New Image– New Layer=trunk– New Layer=trunk shadow– New Layer=branches– New Layer=leaves– New Layer=darker leaves

• View and New View is a great tool for viewing the image when editing


Questions?

• Do we have any questions at this point?• Next skill working with selections in GIMP.


Selection

• Working with selections• Select by Color and

Fuzzy Select• Bezier paths• The Intelligent Scissors

Tool• Modifying selections

• The Quick Mask• Layer Masks


Working with Selections

• When you have an object selected with Marching Ants you can apply the many different features in GIMP to change the selection to fit what ever graphic effect you need.


Marching Ants• The marching ants effect is an

animation technique often found in selection tools of computer graphics programs. It helps the user to distinguish the selection border from the image background by animating the border. The border is a dotted or dashed line where the dashes seem to slowly walk sideways and up and down. This creates an illusion of ants marching in line as the black and white parts of the line start to move

• Source: http://en.wikipedia.org/wiki/Marching_ants

http://en.wikipedia.org/wiki/Marching_ants


Selection Tool Menu

• Main Image Window– Tools– Selection

• Rectangle• Ellipse• Free• Foreground• Fuzzy• By Color• Intelligent Scissors


Select by Color and Fuzzy Select

• Select by Color is a very valuable tool in your selection arsenal.– Select, By Color– Free Select Tool– Edit Copy– Paste as New Image– Repeat the process on

the next color region.


Bezier Paths• Bezier Paths Tool-lets you define

control points (also called anchor points, or nodes)outlining your object.– Defining a Path– The Paths Dialog– Curved Paths– Adding Nodes or Segments and

Moving Paths– Moving or Modify an Existing Path

• CTRL Click or Enter on your starting point.

• Edit Copy, Edit Paste as New Image .

• You now have a new image of what you created a path around.


Intelligent Scissors Tool• Works somewhat like the Bezier

paths, but with a twist: it tries to follow the boundaries of an object.

• Caution: You must close your selection by clicking on the first point; that is not an option like it is in the Bezier path tool.

• CTRL Click or Enter on your starting point.

• Edit Copy, Edit Paste as a New Image. You now have a new image of what you created a path around.


The Quick Mask

• Lets you see your selection visually superimposed on the image instead of the usual “marching ants” view.

• Everything not selected will have a red translucent red mask over it.

• Quick Mask mode is turned on by pressing the small square at the bottom-left corner of image window.


Layer Mast• Layer masts are particularly useful

when combining images• Lets take an ostrich and a giraffe

and make an ostraffe?• Copy the ostrich image• Click on the giraffe image

– Edit Paste as New layer– Move the body into position– Use the Layers Tool and slide the

opacity level to blend the two layers to your satisfaction.

– Layer, Mask, Add Mast Layer– You can use the Master Layer edit

over the unwanted areas– Great you know have a ostraffe


Erasing and Touch Up

• Darkroom Work with Dodge and Burn– Dodging– Burning

• Smudging Blemishes Away

• The Clone Tool, for More Difficult Jobs– Setting the Clone Source– Fine-tuning a Clone Job– Clone Tool Options


Erasing and Touch Up Continued

• Copying Small Regions• The Heal Tool• Perspective Cloning• Enhancing Specific Regions:

The Blur/Sharpen Tool– Sharpening with the

Convolve Tool– Blurring with the Convolve

Tool

• Blurring Backgrounds with Gaussian Blur


Colors

• Color Balance• Hue- Saturation• Colorize• Brightness-Contrast• Threshold• Curves• De saturate


Filters

• The Filters Menu– Blur– Enhance– Distorts– Light and Shadow– Noise– Edge-Object– Generic– Artistic


Effects

• The Effects are submenus under Filters Menu

• Blur– Enhance

• Blur• Motion Blue


Questions?

• Do we have any questions at this point?• Next skill creating a simple animation using in

GIMP.


Making a Simple GIF Animations

• Plan and storyboard your animations• Animations are a fun use of layers.• Each layer becomes a frame of video.• First frame is the lowest layer• Create an image big enough for every part of

the animation.• Our Project is to create a bi-plane landing and taking off.


Making a Simple GIF Animations

• Create a base Image• Add the Animation Frames• Give Each Frame Its Own Background• Test Your Animation• Animation for Web: Save as GIF


Create a base Image

• New Image– Image Size

• Width= 1024 pixels• Height=170 pixels• Landscape

– Advance Options• Resolutions(y=72; x=72)

• Add background sky color using color picker– Color code=c1d9eb

• Save as bi-plane_landing


Biplane Image

• Open the biplane image in GIMP

• Select image• Edit Copy or Ctrl-C


Create Layers for Animation• Edit >Paste• Look in the Layers Tool and you

will see a Floating Layer • To convert the Floating Layer>Layer and add New Layer, the

Floating Layer is now a normal layer

• Use the Move Tool to reposition the biplane

• Repeat commands until you have the number of frames needed for your animation

• Do not worry about layer names we rename those later.


Test Your Animation

• Main Image Window• Filters• Animation• Playback• New window opens • Click on the Play Button– Enjoy your creation


Fine Tuning Your GIF Animationwith Layer Names

• Next we to copy the background layer and then merge the biplane layer by merging layer, using merge move down

• You can specify the time interval between frames by editing the frame names

• By double-clicking on the layer name in the Layers Dialog Box.

• Give the layer name that ends in millisecond interval (in parentheses).

• Example name: biplane (200ms)• 1000 milliseconds equals 1 second


Animation for Web: Save as GIF

• Main Image Window• File Menu• Save AS• Select File Type– GIF Image


Animation for Web: Save as GIFnext step

• Save as GIF– Interface– GIF Comment (enter

what you what)

• Animated GIF Options– Loop forever– Delay (100 milliseconds

per frame is default)– Use delay entered above

will set times for all frames

Image File Types

• JPEG• GIF• PNG •XCF

•TIFF

• Other Formats

wilber.jpg

wilber.png


Joint Photographic Experts Group• Category (jpg)

– Raster Image Files • File Description

– Compressed graphic format standardized by the Joint Photographic Experts Group (JPEG); supports up to 24-bit color, which makes JPEG a good format for storing digital photos; compressed using lossy compression, which may noticeably reduce the image quality if high amounts of compression are used.

JPEG images are commonly used for Web graphics and for storing photos taken with digital cameras. They are usually saved with a .JPG extension.

• Source: http://www.fileinfo.com/

http://www.fileinfo.com/


Graphical Interchange Format File• Category (gif)


– Image file that may contain up to 256 indexed colors; color palette may be a predefined set of colors or may be adapted to the colors in the image; lossless format, meaning the clarity of the image is not compromised with GIF compression.

GIFs are common format for Web graphics, especially small images and images that contain text, such as navigation buttons.

GIF images can also be animated and saved as "animated GIFs," which are often used to display basic animations on websites; they may also include transparent pixels, which allow them to blend with different color backgrounds; however, pixels in a GIF image must be either fully transparent or fully opaque, so the transparency cannot be faded like a .PNG image.

• Source: http://www.fileinfo.com/



Portable Network Graphic• Category (png)


– Image file stored in the Portable Network Graphic (PNG) format; like a .GIF file, contains a bitmap of indexed colors under a lossless compression, but without copyright limitations; commonly used to store graphics for Web images.

The PNG format was created in response to limitations with the GIF format, primarily to increase color support and to provide an image format without a patent license; additionally, while GIF images only support fully opaque or fully transparent pixels, PNG images may include an 8-bit transparency channel, which allows the image colors to fade from opaque to transparent.

PNG images cannot be animated like GIF images; however, the related .MNG format can be animated; PNG images do not provide CMYK color support because they are not intended for use with professional graphics; PNG images are now supported by most Web browsers.

eXperimental Computing Facility

•Category (XCF)• Raster Image Files

•File Description• Image file created by the GNU Image Manipulation

Program (GIMP), a freely distributed image editing program; saves layers, channels, paths, guides, and the current selection when saved.

•Source: http://www.fileinfo.com/



Tagged Image File Format

• Category(tiff)– Raster Image Files

• File Description – Graphics container that can store both raster and vector images; may

contain high-quality graphics that support color depths from 1 to 24-bit; supports both lossy and lossless compression; also supports multiple layers and pages.

TIFF files were designed to be a standard image format for saving high-quality color images on multiple computer platforms; they are most often seen with the .TIF extension.

The TIFF format was originally developed by Aldus, who merged with Adobe Systems in 1994


Image File Formats

• There are more image formats. Here are some of the most common:– RAW– BMP– PCD– PSD– ICO– PDF and PostScript– SVG– Source: http://www.fileinfo.com/
