2021-12-01fix crash when zooming out on small images (#178)mamg22
When rendering images, destination image width and height may become zero due to float-to-int conversion after zoom calculation, later crashing when creating an image using those dimensions. This sets a minimum of 1 to both variables. Closes #82
2021-11-26fix: img_load_gif: out-of-bound accessNRK
according to imlib2's gif loader, bg should already be transparent black if bg > cmap->ColorCount
2021-11-26Revert "fix: out-of-bounds access when bg not in color map"NRK
with this patch certain gif images will fail to play. one other problem here is that it suddenly breaks the loop without free-ing data and rows, leading to a memory leak. regardless, this needs to be investigated further. here's an example image where this happens: https://i.postimg.cc/SQf1TJJg/awoo-study.gif This reverts commit cca7834e6718c6ff64da42ed5e9770880a3e8ff6.
2021-11-25allow configuring imlib2's cache size (#171)N-R-K
by default imlib2 uses a 4mb cache, which is quite small. this allows users who have more memory to spare to set a bigger cache size and avoid reloading an already viewed image if it fits into the cache. Co-authored-by: Berke Kocaoğlu <berke.kocaoglu@metu.edu.tr>
2021-11-20mark functions and vars as static (#146)N-R-K
the goal here to mark functions and variables not used outside the translation unit as static. main reason for this is cleanliness. however as a side-effect this can help compilers optimize better as it now has guarantee that a certain function won't be called outside of that translation unit. one other side-effect of this is that accessing these vars/function from config.h is now different. if one wants to access a static var/func from different translation unit in config.h, he would have to create a wrapper function under the right ifdef. for static functions one would also need to forward declare it. here's a dummy example of accessing the function `run_key_handler` from config.h under _MAPPINGS_CONFIG ``` static void run_key_handler(const char *, unsigned); bool send_with_ctrl(arg_t key) { run_key_handler(XKeysymToString(key), ControlMask); return false; } ```
2021-10-28code-style: general cleanups (#137)N-R-K

2021-10-28remove unnecessary animated webp related checkN-R-K
this code snippet was introduced in https://github.com/nsxiv/nsxiv/pull/20/commits/2703809a23bdf3fe426466c7a10f41d747913128 but does not seem to be needed. from what i can tell this is some sort of hack that might've been needed back when we didn't bypass imlib2 when loading webp.

2021-10-26fix: memory leak in img_load_webp (#135)N-R-K
if `multi.cap` is >0 that means `multi.frames` has already been malloc-ed. by unconditionally malloc-ing again, we're losing all the old memory. this makes it so we're only malloc-ing (or realloc-ing) when needed.
2021-10-16Revert "Fix in tabbed with alpha patch (#3)" (#121)N-R-K
This reverts commit c7ca547b55e98914264351502e581fe6ae17ae15. cd710f5 fixed the issue with embedding into a parent that has alpha and partially reverted c7ca547 this commit fully reverts c7ca547 , as these changes aren't needed for embedding into an alpha-parent.
2021-10-12Fix behaviour when TrueColor / 24 bit depth is not available (#114)miseran
* Fix regression introduced in c7ca547 which made nsxiv not start in non-TrueColor X server. * Introduce a new fix for embedding into tabbed-alpha. * Fixes a visual glitch from original sxiv when drawing transparent images in 8 bit depth. In 8 bit PseudoColor, `.pixel` is just an index into the 256 defined colors and thus trying to extract rgb bits from it would result in visual glitch. The values `.color.red` on the other hand and so on are always integers between 0 and 0xFFFF representing the color as expected. * Use XColor for win_bg/fg and mrk_fg Co-authored-by: NRK <nrk@disroot.org>
2021-10-11code-style: fix consistency issues all over the codebase (#94)Berke Kocaoğlu

2021-10-09Make statusbar optional (#95)Arthur Williams
libXft and libfontconfig are now optional dependencies which can be disabled via `HAVE_LIBFONTS=0`. Disabling them means disabling the statusbar. This also does not search for freetype2 header if disabled. Co-authored-by: NRK <nrk@disroot.org>

2021-09-16Rework the build system (#19)TAAPArthur
* Added simple configure script Added simple script to autodetect if optional dependencies are installed and enable/disable them as needed. Note this solution uses the compiler directly instead of an external program like pkgconfig so it doesn't require any extra dependencies. It is intended to work with any arbitrary compiler; it has been tested with tcc and gcc. There are some "breaking" changes hidden here - HAVE_GIFLIB was renamed to HAVE_LIBGIF to match HAVE_LIBEXIF - Simply typing `make` will no longer try to build with optional dependencies * use implicit RM variable * General clean-up in configure - Use printf instead of echo - Format style * honor env PREFIX, use LDLIBS * Revert "General clean-up in configure" This reverts commit 8683c179dbf273a330f9a224a4d481a7bea42c5f. * honor env LDFLAGS if set * Don't set OPTIONAL_LIBS in configure * make OBJ all caps * follow suckless style build system - remove configure script. - HAVE_LIBGIF and HAVE_LIBEXIF defaults back to 1 - unload several varibales onto config.mk - make version all-caps - add -O2 optimization - use CPPFLAGS for includes and defines * Revert "follow suckless style build system" This reverts commit 8bf75b1f68d72df349edba8d998d4659dd956dd8. * Generate config.mk from make * Inlined configure in Makefile * update docs * cleanups - changes to config.mk should trigger a rebuild - remove potentially confusing variables form Makefile * Use install instead of mkdir/cp/chmod when sensible * fixup! Inlined configure in Makefile * Don't generate config.mk on rm -f *.o sxiv * update docs and cleanups - make config.mk silent - mention editing config.mk in README * fallback to 0 if user edits config.mk in unexpected way * add comment on config.mk * remove invalid comment configure script is removed * slight restructure - make version all caps - restructure variables that users may want to edit to top - use CPPFLAGS for defines - add some comments - remove needless echos since we have verbose output now * add echos back Co-authored-by: NRK <nrk@disroot.org> Co-authored-by: Berke Kocaoğlu <berke.kocaoglu@metu.edu.tr>
