COLLAGE VERSION 2.01 SHAREWARE
1. OVERVIEW
Collage is a LOW cost QUICK and EASY to use image viewer. It includes a
number of useful image ENHANCEMENT and EDITING features and a powerful
COLLAGE creation capability. The fact that it is a MDI (Multiple Doc-
ument Interface) application allows you to view and manipulate a number
of images in one main window. Furthermore it is capable of playing back
MOVIES and has the ability to EXPORT frames as images. For a quick look
at some of the features of Collage see section 3.
For registration details (US$10) see Section 10. For developers the Delphi
source code(US$15) is also available. (See section 10)
2. INSTALLATION
Make sure you UNinstall any previous versions of Collage first. To install
simply unzip the Collg201.ZIP file and double click on the setup.exe file.
The install wizard does most of the hard work and will guide you through the
installation. Some example images and collages are also installed.
To uninstall simply go to the windows Settings | Control Panel and activate
the Add/Remove Programs application. Proceed with the removal of Collage.
3. FEATURES
Some of the features of Collage ver 2.01 are briefly summarized here:
* MDI application - can load single or multiple images
* Collage creation - assemble a number of individual
images and save the collage as a single image. This
is quick and easy and allows for different backgrounds
or colors, frames and borders. See the examples.
* Clipboard aware
* Can view a variety of image formats
* Can playback video clips (avi, mpg - depending on windows
configuration) and freeze and export frames as images.
* Image processing routines such as AutoBalance,
Histogram equalization, Linear Contrast Stretch, Smooth
and Sharpen can be used to enhance images.
* Standard set of controls with hot keys - Next, Previous',
Delete, Close, Close All, Save, Save As, Open and plent'y
more!
* Auto fit to screen (Automatically sizes image to fit
screen maintaining aspect ratio)
* Magnify / Reduce capability (Zoom in and out using a variety
of algorithms - choice of 9)
* Resize image capability (Enter width and height values)
* Crop and Paste functionality
* Slide show - adjustable timer allows auto display of a
directory of images
* Windows association of supported image extensions
(Associate the Collage application with the image
extension(s) of your choice in the Explorer and then
just double click on the file name to activate)
* Right click menu of popular commands
* Region of Interest (ROI) aware - using the left mouse
button demarcate a Region of Interest on the image, any
further manipulation of the image with Zoom, Copy or
other image processing function will now effect only
the demarcated area.
* All user settings from the last working session are
recalled i.e. Directory, Zoom Factor, JPG quality
factor etc. Most of these can be set from the 'Options'
menu item.
* Text insertion.
* Border and Frame insertion.
* Move files capability.

5. SYSTEM REQUIREMENTS
Collage has been tested on both Windows 95,98 and Windows NT 4. Although not
necessary Collage works best in a 800x600 graphics resolution. The Color
Palette however must be set at 24 bit True Color or higher.
6. TIPS
Collage is very easy to use. When in doubt consult this Readme file and
remember all the speed buttons on the toolbar have hints which are activated
by holding the mouse cursor over the button and waiting a few seconds (do
not click).
When using Collage one can either load a batch of images at once and then
toggle through the selection using the Cntrl + Tab keys or select the first
image in the directory and hit the space bar to display the next image. Note
pressing the space bar first closes the active image and then displays the
next image. If you wish to retain the active image press the INS key - this
displays the next image with out closing the current image.
Using the Windows95 explorer one can associate most image extensions (jpg,
pcx,bmp etc.) with the Collage application. [In the explorer go to the View|
Option| menu item and open the File Types dialog box. Click on a file type
i.e. 'jpg image' and edit the OPEN command to execute Collage.exe.] This
allows one to double click on an image file name in the Explorer and very
quickly view the image using the Collage application.
ROI - Region Of Interest:
Demarcating a region of interest on an image is undertaken simply by holding
down the left mouse button and dragging the mouse accordingly.Once you have
demarcated an area you can apply one of the available image processing
operations to it for example Zoom In, Invert , Rotate etc. This will take
effect on the demarcated region. Try the Copy and Paste functions - only the
ROI will be pasted to the New Image.
Collage Creation:
I often come across the situation that I have a number of smaller images
that I would like to arrrange on one canvas and save as a single image. For
this I have implemented a utility that enables one to create a collage from
a number of individual images. To do this follow the following basic steps:
- Open the images that you wish to use in your collage compilation.
- Edit these images as you wish i.e. add borders,text etc.
- Now press the Collage Canvas speed button (CC on the ToolBar) in
order to create a background canvas on which to paste your individual
images.(Note if you right click the CC button you can set the back-
ground options of the Collage canvas to your preference.)
- Use the Cntrl+Tab key or the mouse to switch to the image of your
choice and then press the Collage Paste button (CP on the ToolBar or
use the PopUp menu).
- This action transfers the selected image to the Collage Canvas and you
can position your image anywhere on this canvas by moving the mouse.
- At the desired location left click the mouse button and the image will
be anchored at that location.
- Continue this process until all the single images have been placed upon
the Collage Canvas. Text, borders and frames can now also be inserted
on the Collage Image if desired.
- Once your Collage is completed save it as a BMP or JPG.
Viewing Movies:
Collage can also playback AVI movies (or even mpeg/mpg if your windows
configuration allows for this). Note movies and images can exist in the same
workspace. In fact you can even playback multiple movies at the same time.An
exceptional feature of the movie utility is that you can easily freeze a
and extract it as an image (use the export frame button - right most button
on the movie controller).You can then save the image as a JPG or BMP. Note
when extracting frames make sure that the movie display area is not covered
by any other images or partially hidden offscreen.
7. FUTURE ENHANCEMENTS
A number of enhancements are to be made to this version of Collage namely :
* The collage creation utility will be further refined
* Thumbnail creation
* Enhancement of Border and Text insertion utilities
* The playback of video clips will be enhanced - better controller
* Help menu
* Mosaic utility
* Bug fixes will continue.
Any suggestions will be welcome.

The source code will in particular help developers in the following areas of
application development:
- How to handle a Multiple Document Interface (MDI)
- Windows file extension association interface.
- Clipboard aware interface.
- Menu and pop-up menu utilisation.
- How to manipulate BMP's/DIB's.
- How to handle text on an image surface.
- How to write image processing algorithms. (The code for
all the algorithms in the Collage application. i.e. Rotate,
Invert, Sharpen, Smooth, Histogram Equalization etc.)
- And a whole lot more!
