3
00:00:12,286 --> 00:00:13,280
>> Rob BOWDEN: Hi.

4
00:00:13,280 --> 00:00:16,340
Mimi nina Rob, na hebu kupata
nje ambao wamefanya hivyo.

5
00:00:16,340 --> 00:00:20,070
Hivyo, kwa kuanzia na template kwamba
copy.c tayari inatupa, tunaona kwamba

6
00:00:20,070 --> 00:00:22,380
zaidi ya maadili ya ni kwenda
kuwa sawa.

7
00:00:22,380 --> 00:00:25,110
Sisi ni kwenda kuangalia kuhakikisha
kuna infile na outfile

8
00:00:25,110 --> 00:00:29,610
fulani katika mstari amri, sisi ni
kwenda kufungua infile kwa ajili ya kusoma,

9
00:00:29,610 --> 00:00:33,490
sisi ni kwenda kufungua outfile kwa
kuandika, na hatimaye, tunakwenda

10
00:00:33,490 --> 00:00:38,780
kusoma katika headers infile ya, kuangalia
kuhakikisha ni bitmap halali, kuandika

11
00:00:38,780 --> 00:00:43,210
headers kwa outfile, kama vile
copy.c amefanya, na tunakwenda

12
00:00:43,210 --> 00:00:46,080
iterate juu ya infile
Scan mistari katika saizi.

13
00:00:46,080 --> 00:00:49,170
>> Na sasa tunaona tu
mabadiliko katika faili hii.

14
00:00:49,170 --> 00:00:53,680
Kwa hiyo, sisi kusoma katika tatu kutoka infile
kama copy.c gani, lakini badala ya

15
00:00:53,680 --> 00:00:57,240
mara moja kuandika mara tatu kwa
outfile, sisi ni kwenda na mabadiliko

16
00:00:57,240 --> 00:00:58,190
pixel data.

17
00:00:58,190 --> 00:01:02,010
Hivyo sisi ni kwenda kuweka data rangi ya bluu na
0 tu, tunakwenda kuweka kijani

18
00:01:02,010 --> 00:01:06,150
0, na kuacha yetu na tu nyekundu, na
kisha tunakwenda kuandika kwamba kwa

19
00:01:06,150 --> 00:01:07,200
outfile.

20
00:01:07,200 --> 00:01:11,830
Na kisha padding ni kwenda kuwa
sawa kama ilivyokuwa katika copy.c.

21
00:01:11,830 --> 00:01:14,150
Hatimaye, karibu files, kurudi 0.

22
00:01:14,150 --> 00:01:16,070
>> Kwa hiyo, hebu angalia nini kinatokea.

23
00:01:16,070 --> 00:01:24,280
Hebu kufanya whodunit. / Whodunit,
clue.bmp, na lets yanaonyesha kwamba bitmap.

24
00:01:24,280 --> 00:01:25,530
Hebu tuangalie file.

25
00:01:25,530 --> 00:01:27,900

26
00:01:27,900 --> 00:01:30,360
Na tunaona Milo Banana Kampuni yake.

27
00:01:30,360 --> 00:01:31,920
Jina langu ni Rob, na hii ilikuwa whodunit.
