Chifukwa BMP siyimakhala ndi njira ya alpha yoti ikhalemo. M'malo mwake, ma pixel onse ayenera kukhala ndi mtundu wolimba, choncho kuwala kwamkati kumapangidwa ndi kuwala kwamkati - kuwala koyambirira - nthawi yomwe fayilo idzalemba. Sichingakhalepo chilichonse chobwezeretsedwanso pambuyo pake. Ngati chithunzichi chiyenera kukhala patsamba lowala kapena pazithunzi, sinthani ku mtundu womwe umasunga kuwala kwamkati.

Kwa chilichonse chokhudzana ndi zinthu zatsopano, formati yatsopano siyimawononga ndalama zowonjezera ndipo imaletsa kuti nkhaniyi ikhalepo zaka zingapo zapitazo.

Age yekha si vuto - angapo mtundu kuchokera kuti nthawi ndibe bwino, makamaka chifukwa chilichonse chili ndi zaka kuti akwaniritse iwo. Zimene zikukhudza ndi zimene nthawi anaganiza: mavidiyo ang'onoang'ono, mofulumira processors, palibe netiweki, ndi zizindikiro aliyense anafunikabe. Pamene zimene anaganizabebe, mtundu ndi bwino. Pamene iwo sachita, kuti ndi chifukwa chosintha.

Kodi BMP ndi mtundu wa Microsoft womwe ndimafunikira mapulogalamu a Microsoft?

Zinachokera ku Microsoft, ndipo ndi komwe kulumikizana kumatha. Palibe pulogalamu yoyamba yosapezeka komanso palibe chilolezo chokhalapo: mawonekedwe adasindikizidwa, ndizosavuta ngati mtundu wa fayilo umalandira, ndipo zonse zoyendetsa ntchito ndi zida zamakono zawerenga ndi kulemba zaka zambiri. Zomwe mumasintha ndi kukula kwake ndi zinthu, sizopezeka.

Popeza masamba asakatuli amagwiritsa ntchito mndandanda wafupi wa mtundu wa chithunzi ndipo BMP ndi kunja kwa izo - zimakhudza kujambula, kusindikiza kapena kusintha ntchito yogwira ntchito kuposa pa web. Fayilo siyowonongeka; siyikhala ndi decoder patsamba. Kusintha kwa mtundu wa chithunzi cha web-native ndi njira imodzi yosinthira ndipo nthawi zambiri imapangitsa fayilo kukhala yocheperako.
