What Resolution Should Your Images Be?
What Resolution Should Your Images Be? The best way to determine the optimum resolution is to think about the final use of your images. For publication you’ll need the highest resolution, for desktop printing lower, and for web or classroom use, lower still. The following table is a general guide; detailed explanations follow. Use Pixel Size Resolution Preferred Approx. File File Format Size Projected in class About 1024 pixels wide 102 DPI JPEG 300–600 K for a horizontal image; or 768 pixels high for a vertical one Web site About 400–600 pixels 72 DPI JPEG 20–200 K wide for a large image; 100–200 for a thumbnail image Printed in a book Multiply intended print 300 DPI EPS or TIFF 6–10 MB or art magazine size by resolution; e.g. an image to be printed as 6” W x 4” H would be 1800 x 1200 pixels. Printed on a Multiply intended print 200 DPI EPS or TIFF 2-3 MB laserwriter size by resolution; e.g. an image to be printed as 6” W x 4” H would be 1200 x 800 pixels. Digital Camera Photos Digital cameras have a range of preset resolutions which vary from camera to camera. Designation Resolution Max. Image size at Printable size on 300 DPI a color printer 4 Megapixels 2272 x 1704 pixels 7.5” x 5.7” 12” x 9” 3 Megapixels 2048 x 1536 pixels 6.8” x 5” 11” x 8.5” 2 Megapixels 1600 x 1200 pixels 5.3” x 4” 6” x 4” 1 Megapixel 1024 x 768 pixels 3.5” x 2.5” 5” x 3 If you can, you generally want to shoot larger than you need, then sharpen the image and reduce its size in Photoshop. -
Printing Terms
Printing Terms Bitmap - Also called a BMP or a raster image. A digital image that is pixel based and resolution dependent. Bit-mapped images loose sharpness and clarity when reduced or enlarged. These files are specified as a number of pixels wide by the number of pixels high. The number of bits per pixel determines the number of shades of grey or colors it can represent. Bitmaps come in many file formats, a few are GIF, JPEG, TIFF, BMP, PICT, and PSD. These types of images are created in paint programs, by scanning and by digital cameras. Bit- mapped files can also be placed or imported into a vector based file, but they remain raster images. For the promotional products industry, bit-mapped or raster images are not usually the preferred type of art for vendors to work with as they are more difficult to make adjustments such as re-sizing. CMYK - A color model where all the colors are made up of a combination of four process colors. CMYK is an abbreviation for cyan (a blue color), magenta (a red color), yellow and key (black). Color Separations - The process of separating the areas of a piece of art to be printed into its component spot or process ink colors. Each color to be printed must have its own printing plate. For example, if a piece of art was to be printed in 3 spot colors, such as PMS 185C Red, PMS 288C Blue and Black, there would be 3 plates. Each of the 3 plates would contain only the elements to be printed in a specific color. -
Guide to Digital Art Specifications
Guide to Digital Art Specifications Version 12.05.11 Image File Types Digital image formats for both Mac and PC platforms are accepted. Preferred file types: These file types work best and typically encounter few problems. tif (TIFF) jpg (JPEG) psd (Adobe Photoshop document) eps (Encapsulated PostScript) ai (Adobe Illustrator) pdf (Portable Document Format) Accepted file types: These file types are acceptable, although application versions and operating systems can introduce problems. A hardcopy, for cross-referencing, will ensure a more accurate outcome. doc, docx (Word) xls, xlsx (Excel) ppt, pptx (PowerPoint) fh (Freehand) cdr (Corel Draw) cvs (Canvas) Image sizing specifications should be discussed with the Editorial Office prior to digital file submission. Digital images should be submitted in the final size desired. White space around the image should be removed. Image Resolution The minimum acceptable resolution is 200 dpi at the desired final size in the paged article. To ensure the highest-quality published image, follow these optimum resolutions: • Line = 1200 dpi. Contains only black and white; no shades of gray. These images are typically ink drawings or charts. Other common terms used are monochrome or 1-bit. • Grayscale or Color = 300 dpi. Contains no text. A photograph or a painting is an example of this type of image. • Combination = 600 dpi. Grayscale or color image combined with a line image. An example is a photograph with letter labels, arrows, or text added outside the image area. Anytime a picture is combined with type outside the image area, the resolution must be high enough to maintain smooth, readable text. -
Resolution and LPI
Resolution and LPI Pixels: Raster graphics are made up of a grid of pixels. When viewing 100% or less on a monitor (72 dpi resolution) the individual pixels are not visible to the eye. If the dpi is lower such as in Example 1 you can see the individual pixels and can't really tell what the image is. Similar to when you zoom in on an image. Images that are only going to be viewed on the screen can be created or scanned at 72 dpi DPI or PPI: Dots per Inch or Pixels per Inch. Monitor and Scanning DPI/PPI: You will hear these terms used interchangably and in this case they refer to monitor view perimeters or the scanning resolution you select. When scanning or creating an image to be viewed on a monitor or projection device the dpi/ppi should be the same as the monitor - thus 72 dpi or a 1:1 ratio. Printer DPI/PPI: Your output device has a dpi resolution also. This is the number of dots it can create within a square inch. Example 2 shows that on a laser Example 1: Pixels Enlarged printer a number of dots can make up a halftone dot depending on the line screen selected (more about that later). When scanning or creating images that will be printed you need to capture more information about the image due to the printing process. The ratio you utilize must then be higher. But how high is enough. If your dpi is very high the file is huge. -

Revisiting XSS Sanitization
Revisiting XSS Sanitization Ashar Javed Chair for Network and Data Security Horst G¨ortzInstitute for IT-Security, Ruhr-University Bochum [email protected] Abstract. Cross-Site Scripting (XSS) | around fourteen years old vul- nerability is still on the rise and a continuous threat to the web applica- tions. Only last year, 150505 defacements (this is a least, an XSS can do) have been reported and archived in Zone-H (a cybercrime archive)1. The online WYSIWYG (What You See Is What You Get) or rich-text editors are now a days an essential component of the web applications. They allow users of web applications to edit and enter HTML rich text (i.e., formatted text, images, links and videos etc) inside the web browser window. The web applications use WYSIWYG editors as a part of comment functionality, private messaging among users of applications, blogs, notes, forums post, spellcheck as-you-type, ticketing feature, and other online services. The XSS in WYSIWYG editors is considered more dangerous and exploitable because the user-supplied rich-text con- tents (may be dangerous) are viewable by other users of web applications. In this paper, we present a security analysis of twenty five (25) pop- ular WYSIWYG editors powering thousands of web sites. The anal- ysis includes WYSIWYG editors like Enterprise TinyMCE, EditLive, Lithium, Jive, TinyMCE, PHP HTML Editor, markItUp! universal markup jQuery editor, FreeTextBox (popular ASP.NET editor), Froala Editor, elRTE, and CKEditor. At the same time, we also analyze rich-text ed- itors available on very popular sites like Twitter, Yahoo Mail, Amazon, GitHub and Magento and many more. -
Workshop 1: Introduction to LATEX
Workshop 1: Introduction to LATEX Dan Parker and David Schwein Sunday, September 21, 2014 Welcome to the first of the Science Center’s LATEX workshops! By the end of today’s workshop, you will be able to write a basic LATEX document containing mathematics. We assume that you have a working installation of LATEX and a LATEX editor. If you do not, please consult the installation guide. 1 Introduction 1.1 Questions and Answers What is LATEX? LATEX is a document preparation system, the de facto standard for mathematics, physics, and computer science. More technically, LATEX is a set of macros – extra commands – for the pro- gramming language TEX. Donald Knuth created TEX in the seventies because he was unhappy with the typography in one of his Art of Computer Program- ming books. He designed the program specifically for typesetting mathematics, and it was widely adopted in the years following its release. Later, in the eight- ies, Leslie Lamport wrote LATEX to extend TEX’s mostly low-level functionality. Today, LATEX has largely superseded TEX. Why should I use LATEX? 1.L ATEX documents are beautiful. Their typography is outstanding, espe- cially as compared to something like Microsoft Word. 2.L ATEX can make almost any document you can imagine and many others besides. 3.L ATEX is free, fast, and has virtually no bugs. LATEX is not for everyone, even among academics. While designing these workshops we found, for instance, that the chemistry department at Brown 1 does not care for LATEX. But mathematicians should certainly use LATEX, mainly because people will not take you seriously if you don’t.1 For the same reason, papers in other math-heavy scientific disciplines, such as physics and computer science, should also be prepared using LATEX. -
Using the WYSIWYG HTML Editor
Using the WYSIWYG HTML editor Purpose: This third-party editor, called ‘CKEditor’ is used to create web pages in a number of tools within WebLearn, such as Resources, Lessons, Forums, Announcements etc. Default permissions: There are no permissions associated directly with this editor. Access to it depends upon permission settings for each tool that uses it. This guide will show you some of the most commonly-used features of the WYSIWYG editor. WYSIWYG is an acronym for ‘What You See is What You Get’, referring to the fact that you can create web pages without having to write the source code (HTML). A comprehensive User’s Guide is available by clicking on the icon within the editor. Other useful step-by-step guides to read in conjunction with this one: Building the Home Page Resources Attaching files in WebLearn All step-by-step guides are available from weblearn.ox.ac.uk/info Introduction This editor will work with the following browsers: Firefox: latest stable version Internet Explorer: 8.0, 9.0 – close to full support; versions 10 and 11: full support Safari: latest stable version Opera: latest stable version Google Chrome: latest stable version There is much more help available online for this editor than is either necessary or practicable to include in this document.

Using Fonts in Applications
Using fonts in applications I. Font management skills for users on the go A. Why? You want to use different fonts in the documents that you create B. You activate and use the best fonts possible for the job C. Issues: you send the document to someone/ someplace/some other computer who does not have the fonts you used to format the text 1. Send a document to a professional print- shop 2. Email a document to a client/friend/col- league (professional or personal) D. What might happen? 1. Bad: error messages or font substitution happens when the document is opened and all your careful formatting is lost 2. Good: font is installed first and then the document opened 3. Good: font is somehow embedded in the document so that the font isn’t needed in the receiving computer (done in application) 4. Good: font automatically activates (3rd party font mgmt program) Ex: Fusion has a pref- erence to automatically activate fonts used in Office documents and plug-ins for Quark, Illustrator and InDesign II. Popular text apps that deal with missing fonts A. Introduction 1. Each application deals with missing fonts differently on the receiving end. This class will cover Microsoft Word and InDesign (both focus on text formatting) 2. This is why it’s good to have a list of the fonts that are installed with a particular application like Office or Creative Suites — hopefully to avoid the problem B. Microsoft Word (simple approach) 1. Word documents are now opened on computers that don’t have some or all of the docu- ment’s fonts, and then Word - very quietly, without telling you - uses font substitution to enable the computer to display the document text and print it. -

Why use LATEX? LATEX vs WYSIWYG Obtaining LATEX Making a first LATEX document Hello world example What is LATEX? LATEX is. I A program that takes a plain text file with codes as input and produces a output document I This process is usually called compiling I The input is a plain text file with .tex extension I The output is a multipage vector based image file. In the past this was .DVI but nowadays mostly pdf and postscript are used I We will use .pdf, which can be created with the pdfLATEX program I The programming language in which the input file is written What is LATEX? LATEX refers to the programming language used to write the input file and the program used to interpret this file and compile the output file. It does not refer to an editor in which you write the input file. What is LATEX? Simple representation: .tex / pdfLATEX / .pdf other files WYSIWYG programs I LATEX is completely different from What You See Is What You Get programs (WYSIWYG) you are used to I For example: I Microsoft Word I Openoffice.org I LibreOffice I The main difference between the the two is that in WYSIWYG programs you directly edit the output file while with LATEX you edit the input file Disadvantages of LaTeX vs.
