Amachita. BMP ndi mwamsanga raw uncompressed RGB mizere ndi header ochepa, kotero kuti ndi bwino lossless ndi zochuluka - nthawi zambiri 10-20x kukula kwa chithunzi chimodzimodzi monga PNG. Ichi ndicho chomwe chimatsimikizira ngati chigawo chachiwiri chimayenda mwaulere kapena chimawononga kubwezeretsa koyamba.
Pali china chilichonse chokhudzana ndi BMP chomwe ndingadziwe?
+
Ndikofunika - chifukwa palibe chomwe chimakonzedwa, BMP ndi kosavuta kuwerenga ndi kusintha koma kuwononga kutsitsa, ndipo sichibweretsa metadata kuti izikhala. Ndi chinthu chomwe chimafotokoza chifukwa chake fayilo ikuwoneka bwino m'modzi mwa mapulogalamu ndi kuipa m'modzi.
Chifukwa chakuti kuwala kwa chithunzichi kumasungidwa ngati EXIF flag, osati mu pixels, ndipo sikuti aliyense woyang'anira amaona bwinobwino. Kusinthasintha kwa chithunzichi kumasintha zinthu ziwirizi kuti zikhale zofanana — pixels ndi flag zimamaliza kugwirizana, ndipo fayilo imawoneka yofanana kulikonse.
Kodi ndingasinthire magulu onse m'modzimmodzi?

Ndikofunika. Ndikugwirizana ndi kuzungulira kwa thumbnail. Ndikugwirizana ndi kuzungulira kwa thumbnail. Ndikugwirizana ndi kuzungulira kwa thumbnail. Ndikugwirizana ndi kuzungulira kwa thumbnail. Ndikugwirizana ndi kuzungulira kwa thumbnail.
Yes — kutsitsa set ndi iwo kusonkhana mofanana pansi pa imodzi set of settings. Lossless owona ndi zikuluzikulu, kotero lalikulu gulu ndi kugwirizana ndi kutsitsa wanu galimoto kuposa ndi kusonkhana yekha.
Kodi alpha channel kupulumuka?
+
Ndiko. PNG ndi TIFF zimagwiritsa ntchito ma channels a 8-bit alpha ndipo zimasungana mpaka pamapeto. Zimakonzedwa ngati mwasankha mtundu womwe sumakhala ndi ma channels alpha, ndipo m'njira imeneyi ma pixels owoneka bwino amaphatikizidwa pa mthunzi wobiriwira.
Kodi pali malire a kukula kwa fayilo pa Kusinthanitsa BMP?
+
Yesani: maakaunti aulere amapanga zithunzi mpaka 25 MB; mabungwe osatha kuwononga amawononga malirewo mofulumira kuposa zithunzi, chifukwa palibe chomwe chimatulutsidwabe. Ngati muli pamwamba pa izi, kusinthidwa kwa PNG kumayamba nthawi zambiri kumatha kukwanira - BMP ndi nthawi yambiri ya zaka makumi asanu ndi awiri ndi kukula kwa chithunzi chofanana ndi PNG.
Nchifukwa chiyani malo a PNG amalandira Kusinthanitsa BMP?
+
PNG.to imapangidwa m'njira yomwe mumagwiritsa ntchito pamene simungathe kuwononga pixel: osatha, alpha-oyenera, ndi yankho loyenera kwa zithunzi zazithunzi, ma logo, line art ndi chilichonse chomwe chili ndi maziko olimba. Ntchito ya chithunzi siyimangokhala ndi gawo limodzi: anthu amafika kuti asinthire mtundu ndi kuchoka kufunikira chithunzi cha mtundu wina, kulemera kosiyana kapena mtundu wina. Kuyendetsa Kusinthanitsa BMP pamodzi ndi kutsitsa, ma caps amtundu umodzi ndi akaunti imodzi ndichifukwa chake ndi apa ndipo si pa tabu yachiwiri.
Kodi ndingachite chiyani ndi zotsatirazi pamene Kusinthanitsa BMP yatha?
+
Wosintha patsamba lino amasintha zithunzi ku PNG, JPG, WebP, GIF ndi SVG - zomwe ndi njira yomwe lamulo la kuwala kwa chilengedwe limapangidwa. Izi ndi njira yomwe anthu ambiri adapita, ndipo amachita izi pambuyo pa Kusinthanitsa BMP kuposa kale, kumatanthauza kuti kusintha kwa ntchito kumachokera ku fayilo yomwe mwamaliza kukhazikitsa.
Kodi Kusinthanitsa BMP pano ndi chinthu chomwecho chomwe masamba a sibling amayendetsa?
+
Magalimoto amagawana - mabuku omwewo, ogwira ntchito omwewo, ma limits omwewo. Zosiyana ndi malangizo, ndipo malangizowa amayamba kuchokera ku chinthu chimodzi chokhudza mtundu womwe umagwiritsidwa ntchito patsamba lino: palibe slider yabwino yosayenera - PNG imayenda m'mphepete mwa maulendo a bit-exactly, choncho chinthu chokhacho chomwe chimasintha mtengo wanu ndi kukula kwa fayilo. A PNG sitepe amaganiza za komwe PNG ndi malo abwino komanso komwe si, ndipo lamuloli limatanthauza zambiri kuposa batani.
Kodi ndiyenera kukhala ndi akaunti, ndipo kodi zinthu zina zimasunga?
+
Sichingakhale akaunti, ndipo palibe chomwe chimasunga: zotsitsa zimachotsa ntchito za ogwira ntchito pambuyo pomaliza ntchito, ndipo palibe chomwe mumapanga chimasinthidwa, kupezeka kapena kugwiritsidwa ntchito kwa chilichonse. Maakaunti aulere alipo kwa mbiri ndi kukula kwa batani, osati kulowa.
