If we are a web developer, we often need some attractive stuffs to be included in our web project. Common stuff of it is flash or gif animation. But, because flash animation need flash plugin to be able to be played in browser, and also because of the filesize, flash animation would make our website heavier –and we all know, heavy-to-load web page is ultimately annoying.
The better solution is to use gif animation. It is extremely light and ultimately flexible to be included in web page. In Windows, we could make gif animation easily using Image Ready. And how about Linux? Once again, do not worry! We've already had the way. The app we need to create gif animation in Linux is gifsicle. It is a command-line app, but don't be afraid, it ain't horrible but very simple and easy.
Here it is the steps :
1. Edit our image to be multiple frames, and save them as gif. We could do this using GIMP (which has capability to save into gif). Or we could do this using other simple image editor like Kolourpaint and save them as jpeg, and then we just need to convert them as gif.
2. If we're not yet have gif images, we have to convert them into gif using phatch. I've posted the way to convert multiple image in Linux HERE.
3. We have to arrange our images as frames by renaming them to be sequence (e.g. : 0001.gif, 0002.gif, 0003.gif and so on).
4. Now, we just need to execute gifsicle command like this :
gifsicle --delay=100 --loop *.gif > anim.gif
(delay in a centisecond = 1/100 second. 100 = 1 second)
5. And yes, we've done creating a gif animation using Linux and FOSS app !
Installation
Gifsicle is popular, we can install it through the repo of our distro we use. In Debian and Ubuntu, it is installable by apt : sudo apt-get install gifscile
Conversion process
Step 4. Last step, click continue
Step 3. Select image collection folder
Step 2. Select Filetype as gif / or another
Step 1. Add Action SaveFor some reasons, we need to convert our image collections from one to another format (e.g : from jpeg into png, gif etc). In Linux, we have had convert, a command-line tool, part of the popular tool imagemagick. But, in order to convert multiple images at once, undertaking it using convert is absolutely difficult (I've tried, and followed the manual, but always been failed).
But, don't worry! We have a great solution. In Linux, there is already a GUI tool to do very complex actions of image manipulation called PHATCH. Now, here it is the steps :
1. Open phatch, and select “Add an action” button.
2. Scroll down, find and select action “Save”.
3. In Save action dialog, there are columns about image profile we want to convert. Select “As” and select the format we wanted (ex : gif). Let other columns (Filename etc) without change. Last, press button “Execute the action”.
4. Next, we will meet file browser window. Just select Browse Folder and select the folder that contains our image collection/photos that we want to convert.
5. Last, an explorer windows will appears. Just click continue and wait. The process of course depend on how many images/photos we have, and how large the filesize of each.
6. The conversion is done, and now we have our images in new format, and saved in Desktop/phatch.
Installation
Phatch is a popular app. In Debian and Ubuntu, we can install it simply by apt (or other way depends what distro you're using) :
apt-get install phatch
Happy Linuxing ! Long live Linux desktop !
Lagi-lagi saya di tolong oleh aplikasi KDE! Memang pada awal saya menggunakan Linux, saya langsung jatuh cinta pada KDE. Hanya akhir-akhir ini saja saya lebih suka bekerja dengan Gnome karena lebih ringan dan simpel. Pada dasarnya saya tetap jatuh cinta pada KDE, karena keindahan desktop serta kelengkapan aplikasi-aplikasinya.
Kisahnya begini, dari dulu saya selalu mengalami kesulitan saat mencoba melakukan selecting image menggunakan `magic select` di GIMP. Alhasil, saya sering menggunakan `eraser` brush untuk melakukan `magic select` di GIMP.
Dan saya jadi teringat pada desktop Kubuntu, yang mana terdapat aplikasi image editing bernama Krita. Langsung saja saya instalasi :
$ sudo apt-get install krita
Jendela kerja yang jadi satu, serta tool-tool yang `photoshop` look, sangat mudah untuk di operasikan. Dan yang paling enak, sekarang saya bisa menggunakan tool untuk melakukan selecting dan croping dengan lebih mudah.
Satu hal yang agak kurang adalah, Krita terasa lebih berat daripada GIMP. Tapi tak masalah bagi saya.
Selamat berkarya dengan desktop Linux!
