Xav Txog Kev Xav Tau Yav Tom Ntej

Xav txog seb koj qhov kev xaiv hom xav tau kom haum rau yav tom ntej kho, hloov dua siab tshiab, lossis archiving. Rau qhov chaw cov ntaub ntawv uas yuav dhau mus kho ntxiv, xaiv hom ntawv uas khaws cia zoo thiab yoog raws. Rau lub hom phiaj archival, xaiv cov hom ntawv nrog lub neej ntev thiab kev txhawb nqa dav. Qee lub sij hawm tswj hwm ntau lub versions-cov ntaub ntawv tus tswv hauv hom ntawv zoo thiab cov khoom siv hauv cov qauv siv tau ntau dua-yog qhov zoo tshaj plaws rau kev ntsuas qhov xav tau tam sim no thiab yav tom ntej.

Cov lus nug nquag nug txog cov ntaub ntawv tawm tswv yim

Dab tsi yog qhov txawv ntawm lossy thiab lossless compression?

Lossless compression txo cov ntaub ntawv loj thaum khaws tag nrho cov ntaub ntawv qub. Thaum decompressed, cov ntaub ntawv yog zoo tib yam rau tus thawj ua ntej compression. Piv txwv suav nrog PNG rau cov duab, FLAC rau suab, thiab ZIP rau cov ntaub ntawv dav dav. Lossy compression tas li tshem tawm qee cov ntaub ntawv kom ua tiav cov ntaub ntawv me me. Lub degree ntawm kev poob zoo nyob ntawm cov qib compression. Piv txwv xws li JPEG rau cov duab, MP3 rau suab, thiab MP4 nrog H.264 rau video. Lossy hom ntawv feem ntau me dua tab sis txi qee qhov zoo, thaum cov ntawv tsis muaj kev khaws cia zoo tab sis ua rau cov ntaub ntawv loj dua.

Vim li cas kuv cov ntaub ntawv tsis qhib hauv ib daim ntawv thov?

Cov ntaub ntawv yuav tsis qhib rau hauv qee daim ntawv thov rau ntau yam: daim ntawv thov yuav tsis txhawb cov hom ntawv ntawd; cov ntaub ntawv yuav raug corrupted los yog tsis tiav; cov ntaub ntawv tej zaum yuav siv ib tug tshiab version ntawm hom ntawv tshaj li daim ntawv thov txhawb; los yog cov ntaub ntawv txuas ntxiv yuav tsis phim cov hom ntawv tiag tiag ntawm cov ntaub ntawv. Txhawm rau daws qhov teeb meem no, sim siv cov cuab yeej hloov pauv cov ntaub ntawv los hloov mus rau hom ntawv sib xws, hloov kho koj daim ntawv thov mus rau qhov tseeb version, lossis siv lwm daim ntawv thov uas txhawb nqa hom ntawv. Rau cov tswv cuab, koj yuav xav tau cov software tshwj xeeb los ntawm tus tsim tawm hom ntawv.

Kuv yuav siv hom ntawv dab tsi rau kev khaws cia ntev?

Rau kev khaws cia ntev ntev, xaiv cov hom ntawv uas tau txais kev txhawb nqa dav, tsim qauv, thiab tsis tshua muaj tshwm sim. Rau cov ntaub ntawv, xav txog PDF / A, tshwj xeeb version ntawm PDF tsim tshwj xeeb rau kev khaws cia. Rau cov duab, TIFF lossis DNG (rau cov duab tsis zoo) yog qhov kev xaiv zoo. Rau suab, uncompressed WAV los yog FLAC muab lossless zoo. Rau video, xav txog MKV ntim nrog dav txhawb codecs los yog archival-specific hom xws li FFV1. Ib txwm ua qhov tseem ceeb qhib, cov ntaub ntawv tawm tswv yim tshaj cov tswv cuab, thiab txiav txim siab ua ntau daim ntawv theej hauv ntau hom ntawv rau cov ntaub ntawv tseem ceeb. Tsis tu ncua hloov koj cov ntaub ntawv mus rau cov qauv tshiab raws li cov qauv hloov zuj zus.

Kuv yuav hloov ntawm cov ntaub ntawv sib txawv li cas?

Koj tuaj yeem hloov pauv ntawm cov ntaub ntawv tawm tswv yim siv software tshwj xeeb hloov dua siab tshiab, cov kev pabcuam hloov dua siab tshiab hauv online, lossis cov yam ntxwv built-in hauv ntau daim ntawv thov. Rau cov ntaub ntawv tawm tswv yim, Microsoft Office, LibreOffice, thiab Google Docs txhua tus muab kev xaiv export rau ntau hom. Rau cov duab, cov cuab yeej xws li Adobe Photoshop, GIMP, thiab IrfanView muaj peev xwm hloov dua siab tshiab. Rau cov suab thiab video, cov ntawv thov xws li HandBrake, FFmpeg, thiab Audacity yog cov kev xaiv muaj zog. Ntau qhov kev pabcuam dawb hauv online kuj tseem muaj rau kev hloov pauv yooj yim, txawm hais tias yuav tsum ceev faj txog kev xa cov ntaub ntawv rhiab. Thaum hloov dua siab tshiab, nco ntsoov tias qee qhov kev hloov pauv tuaj yeem ua rau qhov tsis zoo lossis tsis muaj cov yam ntxwv, tshwj xeeb tshaj yog thaum hloov los ntawm hom muaj peev xwm ntau dua rau ib qho yooj yim dua.

Dab tsi ua rau cov ntaub ntawv kev noj nyiaj txiag thiab kuv tuaj yeem tiv thaiv nws li cas?

Cov ntaub ntawv kev noj nyiaj txiag tuaj yeem tshwm sim rau ntau qhov laj thawj suav nrog kev kaw tsis raug, kho vajtse tsis ua haujlwm, software kab laum, kab mob kis, cuam tshuam kev hloov pauv, lossis kev cia cov xov xwm degradation. Txhawm rau tiv thaiv cov ntaub ntawv kev noj nyiaj txiag, ua raws li cov kev coj ua no: ib txwm siv qhov “kev nyab xeeb tshem tawm” kev xaiv rau cov tsav sab nraud; khaws koj lub operating system thiab cov ntawv thov hloov tshiab; siv antivirus software; zam kev cuam tshuam cov ntaub ntawv ua haujlwm xws li txuag lossis theej; siv lub tswv yim thaub qab tsis tu ncua nrog ntau daim ntawv theej; siv cov cuab yeej pov thawj cov ntaub ntawv uas tshawb xyuas cov ntaub ntawv ncaj ncees; thiab xav txog kev siv cov ntaub ntawv kaw lus nrog kev kho qhov yuam kev. Yog tias koj muaj cov ntaub ntawv tseem ceeb, tsis tu ncua xyuas lawv cov kev ncaj ncees thiab tsiv mus rau cov ntaub ntawv khaws cia tshiab txhua ob peb xyoos.

Cov thawv ntim khoom yog dab tsi thiab lawv txawv li cas ntawm cov codecs?
