Title: Paint Shop Pro and the Web


1
Paint Shop Proand the Web
  • Rick Matthews
  • Dept. of Physics, Wake Forest University
  • And
  • The International Center for Computer Enhanced
    Learning
  • matthews_at_wfu.edu
  • http//www.wfu.edu/matthews

2
My favorite PSP tricks
  • JPG vs. GIF
  • Layers
  • Raster vs. vector
  • Text and shapes
  • Adjustment layers
  • Fixing exposure problems
  • Color correction
  • File export JPG and GIF
  • Screen capture

3
JPG vs. GIF
  • Nearly all web images are one of these two.
  • Each is a compressed format. Goal small file
    sizegtquick download.
  • Each has compromises, but very different
    compromises.

4
GIF
  • Limit of 256 colors on screen.
  • Shrinks files by looking for areas of uniform
    color.
  • Great for text, line graphs, simple computer art.
    Poor for photographic images.

5
GIF and photos
  • Problems
  • No uniform color, so big files
  • Lots of colors, so poor fidelity.

6
JPG and photos
  • Photo rendition is the design goal of JPG.
  • It is a lossy compression method, discards info
    least likely to be noticed.
  • Huge reductions in file size with minimal quality
    loss.

7
JPG and text, line art
  • JPG is at its worst where GIF is best Large
    areas of uniform color. Below are magnified
    200x100 images.

JPG, 2,400 bytes
GIF, 646 bytes, perfect
8
TIFF, PSP, PNG
  • CAUTION Never use JPG for your working file
    format.
  • Each Save, Load cycle degrades image more.
  • Lossless formats TIFF, PSP, PNG.
  • PSP optimal internal format, but proprietary.
  • TIFF widely supported across multiple platforms.
  • PNG Newest, will eventually replace GIF. Not yet
    well supported.

9
Layers
  • 3 kinds
  • Raster (images)
  • Vector (adjustable objects)
  • Adjustment (affect lower layers, not directly
    visible.

10
Layers
  • 3 kinds
  • Raster (images)
  • Vector (adjustable objects)
  • Adjustment (affect lower layers, not directly
    visible.

11
Layers
  • 3 kinds
  • Raster (images)
  • Vector (adjustable objects)
  • Adjustment (affect lower layers, not directly
    visible.

12
Example Levels and color
  • Levels let you intuitively (and reversibly)
    correct brightness and contrast.
  • Uses adjusment layer.
  • Color balance is another adjustment layer.

13
Example Gamma
  • Handy when dark areas need to be lightened more
    than brighter areas.
  • Consider working on duplicate layer, to save
    original.

14
Transparency
  • Handy trick to create header images for web
    pages, backgrounds for PowerPoint slides
  • Must create a duplicate layer, then make
    background white.

15
Screen capture
  • Handy for tutorials on software.
  • Easy way to grap images that were not intended to
    be grabbed.

16
PowerPoint
17
Steps in creating a PowerPoint presentation
  • Choosing a presentation template
  • Choosing a format for each slide
  • Images
  • Animation
  • Sound, Narration
  • Export to Web

18
Presentation template
  • Appropriate theme?
  • More important contrast

19
Layout
  • Think about leaving room for illustrations,
    pop-ups.
  • Can always delete text boxes.
  • Inserted text boxes have defective bullets.

20
Inserting images
  • Can use Insert, Picture, File, or
  • Copy and paste from PSP.
  • Best to size images in PSP first, rather than
    resizing in PowerPoint.

21
Animations
  • Introduces elements of slide sequentially.
  • Choose SlideShow gt Custom Animation
  • Effects controls how it appears.
  • Timing controls when.

22
Narrations
  • Easy!
  • Slide Show gt Record Narration
  • External microphone is recommended.

23
Web authoring PowerPoint vs. direct authoring
  • Uses a tool you may already know.
  • Efficiency much improved in PP2000.
  • Layout is easy, well-defined.
  • Nearly trivial way to post class notes on web.
  • Less flexible layout.
  • Slower viewing, because files are larger.
  • Linear document not a web-like.

24
Publishing your PPT on the web
  • Preview web view under File Menu.
  • To create web page select Filegt Save As Web Page
  • To create web page select Filegt Save As Web Page
  • Default works with IE5 only. To fix, click
    Publish.

25
Miniproject on PSP and Powerpoint
26
Two Miniprojects -- PSP
  • Prepare another image consisting only of vector
    text and shapes.
  • You should have at least 3 layers raster
    background with a uniform color, vector layer for
    text, vector layer for shapes.
  • Save as PSP image, export as GIF.
  • Start with a photographic image.
  • Correct brightness and contrast using levels,
    correct gamma, correct color.
  • Add text overlay
  • Save as PSP, export as JPG.

27
Miniproject -- Powerpoint phase
  • Create a brief presentation, with your choice of
    designs.
  • Create three slides in more than one layout, and
    include at least one picture.
  • Experiment with different animations. Overdo it.
    Be tacky.
  • Add one virtual slide, consisting of sequence
    of slides with fake pop-up boxes.
  • Export to web.
