9va-pi ︰ 緣起

話說在網際網路上曾經 GIF 獨領風騷︰

The Graphics Interchange Format (better known by its acronym GIF /ˈdʒɪf/ JIF or /ˈɡɪf/ GHIF) is a bitmap image format that was introduced by CompuServe in 1987[1] and has since come into widespread usage on the World Wide Web due to its wide support and portability.

The format supports up to 8 bits per pixel for each image, allowing a single image to reference its own palette of up to 256 different colors chosen from the 24-bit RGB color space. It also supports animations and allows a separate palette of up to 256 colors for each frame. These palette limitations make the GIF format less suitable for reproducing color photographs and other images with continuous color, but it is well-suited for simpler images such as graphics or logos with solid areas of color.

GIF images are compressed using the Lempel-Ziv-Welch (LZW) lossless data compression technique to reduce the file size without degrading the visual quality. This compression technique was patented in 1985. Controversy over the licensing agreement between the software patent holder, Unisys, and CompuServe in 1994 spurred the development of the Portable Network Graphics (PNG) standard. By 2004 all the relevant patents had expired.

由於總是好奇那『幽竟夢卿』裡的『形聲字譜』

尚未進到『幽竟夢 卿』之地界，祇見『林中道』宛如紅紋斑馬導引遠方。原來這裡是用紅外光來照明的啊！入林後，剛走幾步，便為一塊看似立牌之物吸引，向前仔細一看，竟然像是 個『顯示器』，而且『耳內』還傳來聽不明的聲音，當真叫人好奇得很。便朝向Mrphs 問道︰這個是什麼呢？ Mrphs 說︰你指的是『日月雙屏』的吧！那是一種並紅外線與可見光的兩用顯示器。據聞是 M♪o 特別為『幽境夢鄉』所設計的。可以在白天和夜晚講解此地景物。還新創了『形聲字譜』，利用『文字辨識』技術，輔以『骨聽傳音』方法 ，既不打擾四周幽靜，又能夠耳中喃喃有語。它以『隔空觸控』來操縱，先生正看的圖像是『古蕉園』，靠近東邊山壁『木火泉』之旁 ，所聽到的『耳語』當是 Tux 語對應之『山野蕉源流』解說史的了。……

9va-pi: Free Animation Editor for Raspberry Pi / Ubuntu- create Animated-GIF / Animated-SVG

 

 

  • 9va-pi is a Raspberry Pi and Ubuntu version of ‘9VAe’ which is the powerful FREEWARE for creating animation ( 9va-mac / 9va-win / 9va-pi(Linux)) . 9va-pi can export animated GIF / SVG SMIL Animation.
  • 9va-pi can create complex animations from fewer keyframes.
  • The following sample animation was created from 2 pages figures and 7 pages layouts as follows:
    The man is walking along the red line shown on the 6th page.
    9va-pi can make all frames for the following sample Animated-GIF from only 9 keyframes !
