Compression . Cov PNG file format featureslossless compression (cov ntaub ntawv me me tab sis qhov zoo sib xws). Nws qhov tsis zoo tsuas yog qhov ntawd compressing tus PNG xav tau kev suav ntau ntxiv, yog li kev xa tawm yuav siv sijhawm ntau dua (li no "qeeb").
nˈd?iː/ PEE-en-JEE los yog /p?ŋ/ PING) yog raster-graphics file-format uas txhawb nqa cov ntaub ntawv tsis zoo compression . PNG cov ntaub ntawv yuav luag ib txwm siv cov fileextension PNG los yog png thiab tau muab MIME media typeimage / png.
interlaced cov duab me dua interlaced duab. > Interlaced dluab yog ntau yooj yim saib-tau. Cov interlace cia koj pom daim duab ua ntej tag nrho cov ntaub ntawv tau raug xa mus (ua rau lawv tshwm sai dua thiab zoo dua -looking) thiab muab rau koj "xav" tias nws tau rub tawm sai dua.
Interlaced duab loads ib tug ntxov degraded version ntawm tag nrho cov duab kom sai li sai tau thiab ces progressivelyrenders cov duab kom meej meej. Interlaced yuav luag ib txwm yuav loj me ntsis hauv cov ntaub ntawv loj. Tsis- interlaced duab yuav thauj khoom hauv cov vuas uas qhia meej cov duab hauv txhua pobzeb thaum nws nce mus thauj khoom hauv daim duab.
Lub full- loj PNG muaj ib cov ntaub ntawv loj ntawm 402 KB, tab sis tag nrho-loj, compressed JPEG tsuas yog 35.7KB.jpgG ua haujlwm zoo dua rau daim duab no, vim tias JPEG compression tau tsim rau cov duab thaij duab. Cov compression tseem ua haujlwm rau cov duab yooj yim-xim, tab sis qhov tsis zoo yog qhov tseem ceeb dua.
