Software requirement specification document

Introduction 1.1Purpose Adobe Photoshop is arguably the most comprehensive and popular photo editor around. In fact, I don’t know a single computer artist who doesn’t use Photoshop on an almost daily basis, regardless of what other programs he or she may use. To edit any type of photo.for exapmle File Formats Supported by Photoshop: Photoshop supports more than 20 file formats for import and export. Support for other formats can be added through plug-ins. The Save As dialog box displays most of the options. Of the different file formats, the ones we most often deal with are PSD, BMP, EPS, JPEG, GIF, PDF, PICT and TIFF · Photoshop: This is Photoshop’s native format, which saves every bit of information and attribute you can create or manipulate in Photoshop. It also is Photoshop’s fastest format for saving. The key with this format is that it saves all Photoshop layers. Use this format for every save except for final output. · BMP: BMP is the native format for Microsoft Paint. It supports 16 million colors as well as a form of compression (RLE) that loses no file information. You will not use it often, but you might like to save a file for use as Windows wallpaper from time to time. BMP is the choice for that application. · JPEG: JPEG (Joint Photographic Experts Group) format has many applications, but the most commonly encountered use is for display of photographic images on the World Wide Web. JPEG allows you to drastically shrink the file size of full-color graphics by using a lossy compression scheme. This means that some data is lost when the file is saved. In Photoshop you have control over the amount of the loss by striking your own balance of file size against image degradation. Because of this lossy compression, ideally you should save only your final edit to JPEG. Reopening the file and resaving as JPEG will cause the file to lose additional information. · CompuServe GIF: GIF (Graphical Interchange Format) was originally created for use with the CompuServe commercial online service, but this format has become one of the two most common graphic formats on the WWW. The most recent version of the format, GIF 89a supports transparency. It is accessed via Photoshop’s File>Export menu rather than from the Save As dialog box. GIF supports only 256 colors. When choosing between JPEG and GIF, consider that JPEG is generally better suited to continuous-tone images such as photographs, while GIF is better suited to high-contrast images and line art. Note also that only GIF supports transparency; all JPEG images are opaque. · PDF: PDF (Portable Document Format) from Adobe is derived from PostScript. It permits a document to be viewed onscreen (and navigated and even printed) exactly as it appeared when created, even if the system on which it is viewed lacks fonts used in the 18

Software requirement specification document document. To view such document, you do need a helper program (Acrobat Reader-available free online) and a browser plug-in. The format is being used more frequently on the World Wide Web. · PICT File: the PICT format is the Macintosh system’s native graphic format. It supports both bitmapped and object-oriented elements. As with BMP, it is a useful choice for an image destined for use on a Macintosh system (any word processor will recognize it), but better choices exist for cross-platform use, for use on the Web and for output to print. · TIFF: TIFF (Tagged Image File Format) is an important standard in the graphics world. While it supports only bitmapped elements, it is probably the single most widely supported format across the Mac and PC platforms. At the time you save, you do have to specify whether to do so in Macintosh or PC format, as there are some minor differences in the TIFF implementation on each. Still, Photoshop on either platform can open either type of file. · EPS: EPS (Encapsulated PostScript) is a format designed for outputting objectoriented graphics (vectors) to PostScript printers. Photoshop can open files saved in EPS format and make use of the mathematical description to smoothly scale the object at the time of import. However, when the import is done, the object is rasterized (converted to a bitmap). The object then behaves within Photoshop like any other element of an image (ie: it becomes simply a collection of pixels). During the import process, you can choose to anti-alias the edges of the object in order to avoid a jagged appearance. Anti-aliasing becomes less necessary as the image resolution increases.

The Two Functions of Photoshop: Generally speaking, the two halves of Photoshop serve different purposes.The straightforward Jekyll tools mostly concentrate on painting, and the more complex Hyde capabilities are devoted to image editing. Therefore, to tackle this great program, you may find it helpful to understand the difference between the two terms.

Drawing and painting without the mess: The Eraser tool erases, the Pencil tool draws hard-edged lines, the magnifying glass magnifies your images, and so on. These incredibly straightforward tools attract new users just as surely as a light attracts miller moths.

Editing existing image detail: When you edit an image, you distort and enhance its existing details. So rather than paint with color, you paint with the image itself.

1.2Product Conventions: As of the latest version of this SRS, CS4 there are no document conventions.

1.3Potentinal Audience and Reading Suggestions: The potential audience is the software engineering class, who will be implementing and testing this image manpulator Adobphotshop. Also, the document is to be utilized by the software engineering professor to evaluate the software design and features.

1.4Project Scope: This program is used mostly to manipulate images. People that do web development, graphic design, and photography will probably prefer the use of this program to edit their images. Once you have grasped this basic knowledge of the software, you will be able to dive into Adobe Photoshop and quite possibly Adobe Fireworks, which works in a similar way. Adobe Fireworks is just a little simpler and has less features. Adobe Fireworks was originated as Macromedia Fireworks.

2.Copmlete Description 2.1Product Perspective Graphic Editor is a stand-alone editing software application. It will read in an image, attempt to automatically correct linear distortion, and allow the user to modify these corrections. The user will also be able to make additional alterations.

2.2Adobe Photoshop Features Selection - This is the most basic but powerful feature of Photoshop. You can select only part of an image wherein you want changes to take effect. This method is done with the use of the tools like the marquee tool, lasso, and pen tools. Layers - Layers is a set of different stacked elements that contains different parts of an image. This is one of the best features Photoshop created. Layering lets you work on different parts of a photo and put them together for a dramatic finish. Image size alteration - This feature enlarges or reduces an image as needed. Cropping - Cropping lets you select a portion of the image you want to retain. It deletes the rest. Sharpening and softening - Photoshop features the power to render a sharper or blurred effect on images. This feature is done by selecting the main subject and applying sharpening or softening effects. This feature is mostly used in portraits to create a better focus on the subject. Merging images - This features allows two or more separate images to merged as one. Removal of unwanted elements - This technique involves the use of clone tool to maintain the texture of the image. This is useful when you want to get rid of distracting objects in an image which gives more focus on the subject. This feature can enhance close up portraits, to erase acne marks in a face. Selective color change - Using this feature lets you alter the color of certain parts of an image, keeping the rest of the colors original. Slicing - This features the ability of slicing a whole image into parts and is labelled with different files and later on used as contents of a website. This feature is automated and widely-used in creating mock-ups of websites. There a lot more features of this great software which you just have to discover and will greatly help you do your image editing task faster and efficient with professional looking results. 18

3.System Features Functional Requirements: To carry out this feature a .Net framework must be installed or the image will only be saved to the local machine with no capability of being seen elsewhere.

3.1Image Saving in Photoshop To save a Photoshop file, select one of the three different save options found in the File menu: 1. Save — The Save option is typically used after an image has already been named and saved. Using the Save option integrates and saves any edits that occurred since the image was last saved. The Save option is available via keyboard shortcut (Ctrl-S for Windows and Cmd-S for Mac) or the File Menu:

File > Save 2. Save As — The Save As option is used to save: (1) a new image that has not been saved before; or (2) an image that has been saved previously but needs to be saved under a different name. When saving a file for the first time, there is no difference between using the Save option or the Save As option; they both bring up the Save As dialog box the first time an image is saved. To save a file using the Save As option, the menu steps are:

File > Save As The Save As dialog box will ask you to identify the folder the image should be saved in, the filename, and the type or format of the file to be saved. An image created or edited in Photoshop is typically saved in the native Photoshop format (.psd or .pdd), but can also be saved in a variety of other graphics formats (e.g., GIF, JPEG, TIFF, etc.). There are several Save Options available within the Save As dialog box. They will be illuminated if they are available with the image being saved. For example, the As a Copy checkbox will typically be illuminated. When checked, this option saves a copy of the original image, leaving the original image open in the Document Window. In this case, the word "copy" is placed after the filename but before the file extension (e.g., kara copy.jpg). In addition, the Color section of the Save As dialog box allows the user to save the specific color profile associated with that image. 3. Save A Version — The Save A Version option is used exclusively with Version Cue.

18

Software requirement specification document File > Save A Version 4. Save For Web — The Save for Web option provides various options relevant for optimizing graphic images for use on the web. We will review these options in detail in the next lesson. In addition, saving images for the web using ImageReady will be discussed as we progress through the web Tech curriculum.

File > Save for Web

3.2Image Loading Load images and textures for filters To produce their effects, some filters load and use other images, such as textures and displacement maps. These filters include the Conté Crayon, Displace, Glass, Lighting Effects, Rough Pastels, Texture Fill, Texturizer, Underpainting, and Custom filters. Not all of these filters load images or textures in the same way. 1.Choose the filter you want from the appropriate submenu. 2.In the filter’s dialog box, choose Load Texture from the Texture pop-up menu, and locate and open a texture image. All textures must be in the Photoshop format. Most filters use only the grayscale information of a color file. Functional Requirements: 1. The user will not be allowed to open an image that does not exist. 2. The file will not open if it is not of the format of gif,EPS,DCS 1.0,DCS 2.0, TIF, JPEG,FLM, PDF, PCX, photo cd,PNG,raw,scitex,tagra,wireless bitmap.
