64a4e58543 quirc.h : Fix C++ function name mangling with extern C. 2017-02-16 14:32:18 -05:00

59182ef1cd Deinterleave blocks correct. 
Use explicit small-block count. Derived value using greedy calculation
wasn't correct in many cases.

93adbb0b11 Avoid division by zero. 
Before this patch, small images (i.e. 7x7 pixels or less) could trigger
SIGFPE because of a (integer) division by zero.

87e79e769b Fix Reed-Solomon decoder. 
Calculate the correct number of syndromes, and fix calculation of the
error locator polynomial. Many QR codes with logos in the middle should
now work.

ab341691c9 Add support for ECI decoding. 
ECI values are decoded and stored in the eci field of struct quirc_data.
Constants of the form QUIRC_ECI_* are defined in quirc.h.

8decf20d4f Strip alpha channel from PNG images with tRNS chunk 
When PNG transformations are set up, tRNS chunk is converted to alpha channel
early in the process.  Later the decision whether to strip alpha channel or not
is made upon checking (color_type & PNG_COLOR_MASK_ALPHA).  Thus alpha channel
created by tRNS chunk conversion does not get stripped.

1de1a466b8 Store time in milliseconds 2016-08-15 00:28:24 +02:00

c13db788bb Use clock_gettime() instead of clock() 
clock() provides approximation of processor time used, measured in "clocks".
Amount of clock per second varies between 100 (Minix, NetBSD, OpenBSD), 128
(DragonFly BSD, FreeBSD, older versions of MacOS X), 1000 (Windows) and 1000000
(Linux, newer versions of MacOS X, Solaris).  The range of these numbers make
conversion to milliseconds (the unit of display in `qrtest`) problematic.
clock_gettime() with its nanosecond time base appears to be a better and more
portable alternative to clock().

35b50246f4 Avoid '$(shell ...)' macro 
$(shell ...) macro is a GNU make extension.  GNU make also supports `!=`
operator, which is more portable.

22cd4d061c Don't compile objects twice 
PIC objects can be used for static library as well, so there is no reason to
build two sets of objects.

3a6efb3d84 Large images decoding support 
Fix #2, this patch makes large images support a compile time option by
allowing QUIRC_MAX_REGIONS to be tuned via CFLAGS up to 65534 (current
default is 254).

09cc95b989 check_if_png: clarify comments. 
Before this patch check_if_png() comment was kind of misleading because
it talked about the behaviour of png_sig_cmp() which isn't the same as
check_if_png().

42c79481e7 decode: support multiple data segments. 
Previously, the payload was assumed to consist of one large data
segment. Now, multiple segments of different types may be concatenated
together. The data type reported is the highest data type encountered
while decoding.
