== Description & Goals==
Read SD Comics is my second attempt at creating a comic book reading Activity for the XO laptop. View Slides was the first. Read SD Comics actually has fewer features than View Slides. You can't share documents, there are no annotations and no support for multiple bookmarks, and you cannot create and edit slide collections. It just reads image collections in Zip and .CBZ archives.
Why create an Activity that does the same thing as View Slides but with fewer features? The answer is simple: Read SD Comics does not read image archives in the Journal. Instead, the comic files are kept on an SD card or other external storage, and the Journal only stores a link to the comic file plus metadata like the page you left off on, title, description, etc.
If you own an XO laptop you should be able to see the advantage of this approach.
The interface to Read SD Comics is similar to the core Read activity, which should not be surprising as the toolbar code was adapted from Read's toolbar. You can use the up and down arrows or the game controller to move from page to page.
=== Slide Collections on the Internet ===
Some books at Project Gutenberg are already in a suitable format. Try downloading this file from [http://www.gutenberg.org/ebooks/21078 Project Gutenberg]. Look for the file format "Raw page images".
If you want to read some free comic books the Internet Archive has a bunch of them. Use [http://www.archive.org/search.php?query=comics%20cbr this query] to see a list of them. They are in the .cbr format, and will need to be converted to the .cbz (Zip) format to be used with View Slides. The program Comix under Linux can do this conversion for you if you have the unrar utility installed, or you can simply unrar the .cbr file to get the images, then package the images in a zip file:
unrar e LoneRangerDell100.cbr
zip LoneRangerDell100 *.jpg
If you use Windows you can use the free [http://www.7zip.org 7zip File Manager] to extract the files from the .cbr and pack them up again in a zip file.
== Current Features ==
* Currently you can load a zip file containing images and page through them in sequence like a book. The images will be resized to best fit in the current screen resolution without scrolling. If you change the screen orientation the image will be resized to fit the new orientation.
* You can hide the mouse pointer (or make it visible again) by pressing the "square" button to the lower right of the XO screen (or numeric keypad "Home" on any other computer). This removes a source of distraction when viewing images.
* You can zoom the image to fit the width of the screen and scroll it vertically. This is handy for reading scanned in books with smaller print. Also new with version 7 you can hide and show the toolbar by pressing Alt-Enter on the keyboard, giving you the ability to view your slides using the full screen.
