Working on review comments for Chapters 2, 3 and 4 tonight

Michael Carden asks in a comment to my previous post to the book if I had considered making draft chapters available for public comment before printing. To be completely honest it hadn't occurred to me until Michael suggested it, and it does fit well with all the open source stuff I have done over the years. It's a hard call though, because there is already a review team of four or five, and there isn't much spare time in the process because we really want the book published in time for Christmas. This is why I'm going to say no this time to the offer of a more public review, and I'll do my best to take that on board next time when I know more about how long this sort of thing can take (I'm actually only about two days over schedule at the moment, but I really don't want to slip any further). Sorry Michael. Anyways, I'm working on review comments for three chapters tonight, which is one of the things that made me think about this more. I'm really rather surprised about how positive the review comments have been so far given how I feel about the…

Why Debian?

Why do I use Debian? Well, one of the reasons is the bug reporting. I think I just found two bugs in ImageMagick, one a simple documentation bug, and the other a functionality bug. With Debian, I can just run the reportbug command from the command line with the name of the package, and walk through the simple bug reporting process, instead of having to fight my way through mailing lists for the dozens of different packages I have installed. It's nice.

ImageMagick book – Chapter 2: Basic Image Manipulation

I'm meant to be writing the rest of chapter seven tonight, but I thought I would warm up by continuing with my promised series of posts about the content of the book. The next chapter in the list is chapter two, which covers simple image manipulations. The idea was to get the stuff which everyone wants to do and cover it as soon as possible so that people can get some runs on the board (so to speak). In chapter two you will find an introduction to the bits of imaging theory that we need for the book (rasters, vectors, bitmaps, pixels, you get the idea). Then I move on to talk about ways to change the size of images. This includes resizing, sampling cropping, scaling, thumb-nailing and so forth. We also discuss some interesting transformations like trim. Then we move onto making an image larger, before finishing up with how to process many images at once with ImageMagick. It's an interesting chapter in that it's immediately useful, and goes through some interesting theory matters. It also sets the stage for the later coverage of all the other cool stuff you can do with ImageMagick. As a point of interest,…

Trying out the Apress e-book system

  • Post author:
  • Post category:Books

Full disclosure: I am currently writing a book for Apress. As an Apress author Apress asked me to check out the Apress e-book online catalog thingie. They threw in a free e-book as an incentive, so I thought I should give it a try. I've done a fair few book reviews for AUUG / Woodslane over the last couple of years, so it seemed like a good idea to look further into this e-book thing anyway. Especially as I have a garage full of books that I occasionally need as references, but don't have the space to store in the house, especially with two small kids who like to draw in books around. So, I picked a book in their online catalog, and said I'd like to buy it. I entered the discount code, and was good to go until they noticed that I didn't have an online account in their system. So, I had to stop my "purchase" and make one. Which meant that my place was lost in the purchase, as I had to wait for a confirmation email to arrive, and then click on a link in that email which didn't have the stage I was up…

Some details about the publication process

Pascal asked in the comments to a previous post about the book about how I was going about writing the book and how the publication process works. It's a good question, and something I meant to cover here anyway, so now seems like a good time. I'll start from the beginning with a brief summary of how I got started with this writing thing. I started off by writing a number of articles for IBM DeveloperWorks. DeveloperWorks are actually really good to work with, all I did to start writing from them was fill in the proposal web form within a couple of hours we'd sorted out what was happening, and off we went. The ImageMagick articles I wrote turned out to be quite popular with the ImageMagick people. I suspect that's why the editor for Apress, a lovely guy named Matt contacted me. He pitched the book to me, and I was originally hesitant. He spent a fair bit of time (a month?) discussing the project with me, and I ended up deciding that because it's fairly closely aligned with the imaging work I'm doing for my PhD, I ended up saying yes. Along the way I wrote a…
