What we’ll cover in this session
 Recommendations on when and how to






use screenshots in user assistance
Potential pitfalls
The basic procedure for capturing screens
Image file formats
Tips for capturing screens successfully
How screen capture tools save work and
add value
Survey of popular screen capture tools
When/why should I use screenshots?
 Identify the appearance and/or location of




a control
Show and explain the layout of a screen
Provide a visual instruction
Show the result of an action
Confirm that user has displayed the
correct dialog box or screen (in tutorials)
Identify the appearance/location of a control
Just enough for easy
recognition and
location of control
Show and explain the layout of a screen
Numbers clearly identify
main regions of the screen
Provide a visual instruction
Image provides same
instruction as text
Refer to a tool or button within text
Show the result of an action
Confirm that user has displayed correct dialog box
Screenshot confirms
success or shows what
dialog box looks like
(unnecessary for
onscreen Help)
When screenshots can cause problems…
 Developers make late changes to the
screens
 The screens need to be localized for many
different countries
Possible solutions:
 Blur or obscure the text
 Draw simplified version of screen
Example: Blurred text
Original screen
capture
Localized text is
selectively blurred –
other dialog elements
remain sharp
Example: simplified screen
Another potential pitfall
Users may not
notice scroll bar
and assume they
are seeing entire
topic
Instructions are out of view
beneath screenshot
Possible solution: thumbnail
Another solution: DHTML dropdown
Capture a window
1. Press <ALT>+<Print Screen>
2. Paste the Clipboard contents into
an image editor
3. Optionally: resize the image (only
necessary for onscreen
presentation)
4. Optionally: reduce the color depth
to 256 colours
5. Save as a file

Resizing screenshots for on-screen presentation
 Reasons to decrease the
dimensions of a screenshot
• Reduce screen space
• Avoid confusion with real screen
 For best quality of resulting
image:




• Use millions of colours (24- or
32-bit) before resizing
• Use an anti-aliasing resize
method

Raster vs. Vector
Raster vs. Vector
Websafe vs. Non-Websafe
Annotated screenshots
1. Capture to a lossless raster format
2. Add annotations and captions using a
3.
vector-based image editor
Store and edit combined image
in vector format
4. Use “Save As” to create raster format as
required
.bmp
 Windows BitMaP
 Typically uncompressed and therefore

very large
Non-Web-Safe
.jpg




Joint Photographic (Experts) Group
Lossy compression
Great for photos, but not for screenshots
Web-Safe
.gif




(Compuserve) Graphic Interchange Format
Lossless compression
Maximum of 256 colours
Web-Safe
.tiff
 Tagged Image Format
 A container format that supports many


types of compression, layers, and different
colour modes including CMYK
Popular for printed publications
Non-Web-Safe
.png





Portable Network Graphics
Lossless compression
Alpha layer for transparency
Does not support CMYK colour
Web-Safe
Size of windows and dialogs at capture time
 If possible, reduce the size of a window or
dialog as much as you can without:
• losing vital information
• making it unrecognizable to the user
Example: Resized window
Original
dialog
Resized dialog
shows all UI
elements
Capture only as much of the screen as the user
needs to see
 Always aim to minimize the dimensions of

the screen capture
Exclude screen clutter that will distract the
user from the main focus
What I look for in a screen capture tool:
Minimum requirements
 Include the cursor




(or easily add it post-capture)
Capture windows, objects,
cascading menus, and rectangular
regions (with precision)
Automatically add border or edge
effects
Automatically use a specified file
format when saving file
Add editable callouts and other
objects on a separate layer
What I look for in a screen capture tool:
Nice to have
 Re-capture a rectangular region
 Save capture to a file without user





intervention
Capture individual buttons
Convert to a specified image resolution
automatically
Capture non-rectangular regions such as
ellipses and polygons
Capture scrolling window
Catalogue/store captured files
Screen capture tools
Let’s look at:
 FullShot – Inbit
 Jing - TechSmith
 MadCap Capture – Madcap Software
 RoboScreenCapture – Adobe
(Bundled with Adobe RoboHelp)
 SnagIt – TechSmith
FullShot (Enterprise Edition)
FullShot’s capture method
 Capture buttons automatically added


to active window
Each button activates a different
capture type (Window, Region, etc.)
Hotkeys can be used as an alternative

FullShot summary
 A popular tool with a good track record
 FullShot Standard Edition automates the



screen capture process very successfully
Uses a different capture mechanism and
workflow from most of its competitors
Interface is fairly complex
Difficult to capture screen regions
precisely
FullShot summary
 For:
• ease of capture
(using title bar buttons)
• wide range of capture shapes and effects
• minimizes file sizes by optimizing the colour
palette
 Against:
• no magnified view of the pointer area for
precise selection of capture regions
• does not enable you to set the colour depth of
a captured image to a specific value
• no support for capturing buttons in the
Standard Edition
Jing
Sharing
button
Jing summary
 A simple and fun to use utility
 It enables you quickly to capture and

share windows, objects, and regions of
your computer screen
It is available for both the Windows and
Mac OS
Jing summary
 For:
• free
• support for sharing screen captures quickly
and easy through a hosted website
• ease of access and use
• support for simple video capture
 Against:

MadCap Capture
Profiles Editor
MadCap Capture summary
 A very interesting and innovative screen


capture tool
Focuses on streamlining the screen
capture workflow rather than necessarily
competing on feature-count
A compelling choice for users of MadCap
Flare
MadCap Capture summary

For:

Against:
• integration with MadCap Flare, and support for
"single-sourcing" screen- and print-oriented image
formats
• ability to reproduce the position and dimensions
of previous region captures
• powerful and multi-layered vector-based image
editor
• reliance on Flare to exploit certain features fully
• steeper learning curve than some of the other
tools
• edge effects (such as torn edge) perhaps not quite
as well implemented as some of the other tools
RoboScreenCapture
Rasterbased
image
editing
tools
Complex
but wellorganized
UI
RoboScreenCapture
Capture Settings dialog
Can be useful for
capturing dropdown menus and
pop-ups
RoboScreenCapture summary
 A well-designed package that enables easy



and very precise capture of regions,
buttons, and other screen elements
Bundled with Adobe RoboHelp versions 7,
8, 9, 10 and has been well integrated with
these products
Not available for purchase as a standalone
product
A little out-dated
RoboScreenCapture summary
 For:
• wide range of capture options including
capture of individual buttons and repeat last
capture
• high level of control over color depth,
resolution, and compression
• precise selection of capture region using
arrow keys
