As the title states.
They are broken.
Lines 141 to 143 in 853b1eb
00 15 00 21 00 32
instead of 15 15 21 21 32 32
for example.
From the official png2ff.c file:
switch(png_get_bit_depth(pngs, pngi)) {
case 8:
for (r = 0; r < height; ++r) {
for (i = 0; i < rowlen; i++) {
row[i] = htons(257 * pngrows[r][i]);
}
efwrite(row, sizeof(uint16_t), rowlen, stdout);
}
My (stupid) fix would be to replace lines 141 to 143 with this:
if (bpc == 8) {
img[p + 0] = htobe16(r * 257);
img[p + 1] = htobe16(g * 257);
img[p + 2] = htobe16(b * 257);
} else {
img[p + 0] = htobe16(r << scale);
img[p + 1] = htobe16(g << scale);
img[p + 2] = htobe16(b << scale);
}
Currently, this software just bails out if the display is not 8bpc.
On my new laptop, I have 10bpc. This needs to be fixed, but I have no idea how.
Hi @shinyblink , @vifino , @g-rden .
$ make
cc -pedantic -Wall -Wextra -Os -lxcb -lxcb-image -o ffshot ffshot.c
/usr/bin/ld: /tmp/ccIPsFIF.o: in function «main»:
ffshot.c:(.text.startup+0x4b): undefined reference to «xcb_connect»
...
Maybe replace:
Lines 14 to 15 in 854c537
$(BINS): ffshot.c
$(CC) $(CPPFLAGS) $(CFLAGS) $^ $(LDFLAGS) -o $@
?
