From 685defa68419654e875a7167a7b09d5398c497a9 Mon Sep 17 00:00:00 2001 From: Přemysl Eric Janouch Date: Wed, 5 Jan 2022 04:42:01 +0100 Subject: Rename the whole project shorter There is no point in claiming speed, it turns out to be a strange focus to have, considering the amount of available innovations to make. The new name does not appear to be taken by anything important. --- README.adoc | 12 +- fastiv-browse.desktop | 11 - fastiv.c | 1384 ------------------------------------------------- fastiv.desktop | 10 - fastiv.svg | 43 -- fiv-browse.desktop | 11 + fiv-browser.c | 2 +- fiv-browser.h | 2 +- fiv-view.c | 2 +- fiv-view.h | 2 +- fiv.c | 1384 +++++++++++++++++++++++++++++++++++++++++++++++++ fiv.desktop | 10 + fiv.svg | 43 ++ meson.build | 12 +- 14 files changed, 1464 insertions(+), 1464 deletions(-) delete mode 100644 fastiv-browse.desktop delete mode 100644 fastiv.c delete mode 100644 fastiv.desktop delete mode 100644 fastiv.svg create mode 100644 fiv-browse.desktop create mode 100644 fiv.c create mode 100644 fiv.desktop create mode 100644 fiv.svg diff --git a/README.adoc b/README.adoc index e1689f5..34ae714 100644 --- a/README.adoc +++ b/README.adoc @@ -1,8 +1,8 @@ -fastiv -====== +fiv +=== -'fastiv' is a fast image viewer, directly supporting BMP, PNG, GIF, JPEG, WebP, -and optionally raw photos, HEIC, AVIF, SVG, X11 cursors and TIFF, +'fiv' is an image browser and viewer, supporting BMP, PNG, GIF, JPEG, WebP +directly, plus optionally raw photos, HEIC, AVIF, SVG, X11 cursors and TIFF, or whatever gdk-pixbuf loads.
