This course covers ways to manipulate images for using on the web. It is part of the five courses related to Web Application Development.
Learning Outcomes

By the end of this course, you should be able to:

  1. Apply concept of digital imaging.
  2. Digitize images using different devices.
  3. Manipulate images using graphic tools.
  4. Create digital images for web page development.

This course is divided into 10 topics. The synopsis for each topic is briefed below:

Topic 1 is an introduction to the concept of digital imaging that briefly discusses the basic knowledge of the tools and devices involved in digital imaging. It differentiates between raster and vector images that are suitable for use, and focuses on the computer as a tool for creating and manipulating the digital images.

Topic 2 introduces the GNU Image Manipulation Program or GIMP, as a computer program used for editing, creating and manipulating digital images. It will also introduce the interface and work space used in digital imaging.

Topic 3 focuses on the tools and features provided in the GIMP software. It explains that each tool in the software plays a role as an agent acting on editing and manipulating images. This topic also describes in depth the types of tools to make the process of transforming images more efficient.

Topic 4 discusses the GIMP software, and how it manages files and the data contained therein with the suitable file format. It explains size and resolution which affect the quality of the images, and also describes how to save files in a number of different formats.

Topic 5 focuses on the GIMP used in repairing imperfections in an image, including retouching and colour corrections. Besides that, there is a brief explanation about the process involved in the making of image manipulation and the suitable tools to edit and modify images.

Topic 6 explains how to combine text with images. Before combining text with the images, there is an explanation on how to identify the function of the text before the process of combining with image begins. There is also in-depth discussion on the process of adding the text to an image, creating text effects and changing text attributes.

Topic 7 describes the use of drawing and painting tools as powerful tools in developing image creation. The elements of drawing consist of shapes and paths which can be used in different drawing styles to make creative images. This topic also shows the ways to make beautiful lines and draw an object using the best tools available in GIMP.

Topic 8 focuses heavily on the effects and filters that are readily available in GIMP. A variety of effects and filters in the software can create beautiful images. In a nutshell, effects and filters allow users to modify an image through programs that has flexible adjustments.

Topic 9 is continuation of Topic 8, on using effects and filters. It introduces advanced techniques to create stunning images. In this topic learners learn about how to use the functions in more advanced techniques in order to create amazing visual effects.

Topic 10 discuses GIMP (GNU Image Manipulation Program), a software that allows various images related tasks such as preparing images to be used for website purposes, alongside an open-source community that contributes to each other across all platforms.
