Ua Koj Cov Yees Duab Luv Nrog Tsawg Zog Tsis Zoo Li Cas
Ib qho ntawm feem ntau cov lus nug hauv relation rau graphics software yog li cas yuav ua rau kom qhov luaj li cas ntawm ib daim duab tsis tau txais blurring thiab jagged npoo. Cov neeg siv tshiab feem ntau xav tsis thoob thaum lawv hloov cov duab thiab pom tias qhov zoo yog qhov tsis zoo. Cov neeg siv kev paub txog txhua yam dhau los paub txog qhov teeb meem. Yog vim li cas rau qhov degradation yog vim bitmapped , los yog raster, duab hom txwv ntawm lawv pixel daws teeb meem. Thaum koj sim los txhim kho cov duab no, koj software yog los ua kom qhov luaj li cas ntawm txhua tus neeg pixel - uas ua rau cov duab daj - lossis nws yuav tsum "twv" ntawm txoj kev zoo tshaj ntxiv ntxiv pixels rau daim duab kom loj dua .
Tsis ntev dhau los, tsis muaj ntau txoj kev rau kev daws teeb meem uas tsis yog siv koj qhov kev hloov kho software hauv txoj kab kev ua haujlwm. Niaj hnub no, peb raug kev nyuaj siab nrog ntau lub sijhawm. Ntawm chav kawm, nws yog qhov zoo tshaj plaws los ntes cov teeb meem koj xav tau los ntawm qhov pib. Yog tias koj muaj kev xaiv kom tau ib daim duab ntawm kev daws teeb meem dua, los ntawm txhua yam txhais tau tias, koj yuav tsum ua li ntawd ua ntej kev daws teeb meem software. Thiab yog tias koj muaj cov nyiaj yuav muab tso rau hauv ib lub koob yees duab muaj peev xwm ntawm ntau dua cov kev daws teeb meem, koj yuav pom tau tias cov nyiaj siv tau zoo dua li yog tias koj tau muab tso rau hauv ib qho kev software. Muaj lus hais tias, muaj ntau lub sij hawm thaum koj tsis muaj lwm txoj kev xaiv dua rau qhov chaw kho mob software. Thaum lub sij hawm ntawd los, ntawm no yog cov ntaub ntawv koj yuav tsum paub.
Resizing thiab Resampling
Feem ntau cov software tsuas muaj ib lo lus txib rau kev tsim kho thiab txav chaw. Resizing ib cov duab yuav hloov cov luam qhov ntev tsis hloov pixel qhov ntev tag nrho. Thaum qhov teeb meem nce ntxiv, qhov loj loj me me ua me dua, thiab lwm yam ntxiv. Thaum koj nce cov teeb meem tsis hloov pixel qhov loj, tsis muaj qhov tsis zoo, tab sis koj yuav tsum xyeem luam loj. Kev hloov cov duab siv resampling, txawm li cas los, yuav hloov pixel qhov ntev thiab yuav nco ntsoov qhia ib qho kev poob zoo. Tias 's vim resampling siv tus txheej txheem hu ua interpolation kom ua qhov loj ntawm tus duab. Tus txheej txheem interpolation kwv yees qhov tseem ceeb ntawm cov pixels software yuav tsum tsim los ntawm cov pixels uas twb muaj nyob hauv daim duab. Kev ua haujlwm ntawm kev sib nkag siab ua rau pom kev loj ntawm qhov duab loj, tshwj xeeb tshaj yog nyob rau cov cheeb tsam uas muaj cov kab ntse thiab cov kev hloov hauv cov xim.
• Txog Cov Duab Loj & Txoj Cai Lij Choj
Lwm cov nam ntawm qhov teeb meem no yog qhov sawv ntawm lub smartphone thiab cov ntsiav tshuaj thiab coj tus cwj pwm ntawm cov cuab yeej pixel. . Cov cuab yeej no muaj ob rau peb qho pixels nyob rau tib qhov chaw nyob los ntawm ib qho pixel ntawm koj lub computer screen. Tsiv ib daim duab ntawm koj lub computer mus rau ib lub ntaus ntawv yuav tsum tau koj los tsim ntau lub versions ntawm tib lub duab (piv txwv li 1X, 2X thiab 3X) kom lawv pom kom pom tseeb ntawm qhov ntaus. Puas yog ib qho nce qhov loj ntawm daim duab lossis nce cov pixels.
Hom Interpolation
Diam duab editing software feem ntau muaj ob peb yam sib txawv ntawm txoj kev rau xam cov pixels tshiab thaum muaj duab peb tau ua kom tiav. Ntawm no yog cov lus piav qhia ntawm peb txoj kev muaj nyob hauv Photoshop. Yog tias koj tsis siv Photoshop, koj lub software tej zaum yuav muaj cov kev xaiv zoo li txawm hais tias lawv yuav siv cov lus sib txawv me ntsis.
- Bicubic yog tus qeeb, tiam sis ua tau zoo tshaj qhov kwv yees tshiab pixel qhov tseem ceeb.
- Bilinear yog ceev tshaj bicubic, tab sis yog ib tug poorer txoj hauj lwm. Ob leeg bicubic thiab paub tsim interpolation tshwm sim nyob rau hauv ib qhov muag plooj, tshwj xeeb tshaj yog thaum upsampling.
- Zej Zog Zej Zog tsis siv qhov sib nkag siab. Nws tsuas yog siv tus nqi ntawm cov neeg nyob sib ze pixels thiab ntxiv cov tshiab pixels tsis tau thaj tsam lawv. Qhov no yog thaum koj tau txais cov jaggies lossis stair-step effect.
Nco ntsoov tias muaj ntau tshaj li peb txoj kev ntawm interpolation thiab txawm siv tib txoj hauv kev software txawv yuav tsim cov kev sib txawv. Hauv kuv txoj kev kawm, kuv tau pom tias Photoshop muab qhov zoo tshaj plaws ntawm kev sib txuas ntawm lwm qhov software uas kuv tau muab piv rau.

Lwm Hom Kev Hloov
Ob peb lwm daim duab li cov kev pab cuam muaj lwm cov resampling algorithms uas thov kom ua tau txoj haujlwm zoo txawm tias Photoshop txoj kev sib tw. Qee qhov no yog Lanzcos , B-spline , thiab Mitchell . Ob peb cov kev pab cuam uas muaj cov txheej txheem ua lwm txoj haujlwm no yog Qimage Pro, IrfanView (tus duab pub dawb), thiab Photo Cleaner. Yog tias koj qhov software muaj ib qho ntawm cov duab resabpling los yog lwm tus tsis hais ntawm no, koj yuav tsum tau xyaum ua tej yam nrog lawv kom pom tias ib qho twg yuav qhia tau koj zoo tshaj plaws. Tej zaum koj yuav pom tias lwm txoj kev sib txawv ntawm cov khoom tsim tau zoo dua nyob ntawm seb cov duab siv.
Stair Interpolation
Qee cov neeg tau pom tias koj tuaj yeem tau txais txiaj ntsim zoo dua yog thaum ua qhov loj zuj zus nyob hauv ntau qhov me me ntxiv es tsis yog ib qho tseem ceeb heev. Cov txheej txheem no yog hu ua stair interpolation. Ib qho kom zoo dua siv stair interpolation yog tias nws yuav ua hauj lwm rau 16-ntsis hom dluab thiab nws yuav tsum tsis muaj software ntau tshaj li tus qauv duab editor, xws li Photoshop. Lub tswvyim ntawm stair interpolation yog yooj yim: tsis siv cov duab loj hais kom ua ncaj qha los ntawm 100% mus rau 400%, koj yuav siv daim duab loj hais kom ua thiab tsuas nce, hais, 110%. Tom qab ntawd koj yuav rov hais dua cov lus txib kom ntau li ntau zaus raws li nws yuav siv los mus rau qhov loj koj xav tau. Obviously, qhov no yuav tsho yog tias koj lub software tsis muaj qee qhov muaj peev xwm hauv automation. Yog tias koj siv Photoshop 5.0 los sis siab dua, koj tuaj yeem yuav Fred Miranda tus taw tes rau kev sib tw rau $ 15 US ntawm qhov txuas hauv qab no. Koj tseem yuav pom cov lus qhia ntxiv thiab cov duab sib piv. Vim tias qhov tsab xov xwm no tau sau tseg, cov qauv tshiab thiab cov cuab yeej cuab tam software tau tsim los tsim ua rau stair interpolation yeej tsis muaj dua.

Qhov tseeb Fractals
LizardTech Txoj Kev Lag Luam Software (yav dhau los ntawm Altamira Group) tau sim ua txhaum los ntawm daim duab daws teeb meem nrog nws qhov kev sib tw-hauv-kev thov technology. Qhov tseeb Fractals muaj rau Windows thiab Macintosh. Nws ua haujlwm li ib lub plug-in rau Photoshop thiab lwm Photoshop plug-in tshaj cov duab editors. Nrog nws, koj tuaj yeem encode qis rau cov ntaub ntawv daws teeb meem mus rau ib qho scalable, tsis pub daws teeb meem hom hu ua STiNG (* .stn). Cov ntaub ntawv STN no tuaj yeem qhib rau txhua lub sijhawm koj xaiv.
Kom tsis ntev los no, qhov kev siv tshuab no yog qhov zoo tshaj plaws rau koj qhov kev txiav txim siab. Niaj hnub no, cov koob yees duab thiab luam yeeb tau zoo dua thiab nqis rau hauv nqe, thiab cov peev hauv Cov Kev Lag Luam hauv Fruity yog tsis raws li txoj cai yooj yim li nws ib zaug. Yog hais tias koj muaj kev xaiv tso koj cov nyiaj rau hauv kev kho vaj tse zoo dua li cov software daws, nws yog qhov zoo tshaj los mus. Tseem, rau qhov kev ntxhov siab heev, Txoj Fractals tseem zoo nkauj heev. Nws kuj muaj lwm cov kev pab cuam xws li cov ntaub ntawv me me uas muaj ntaub ntawv sau cia thiab khaws cia. Ua raws li qhov txuas hauv qab no rau kuv qhov kev ntsuam xyuas tag nrho thiab kev sib piv ntawm Cov Fractals.

Alien Skin Tshuab
Txawm hais tias Genuine Fractals yog thawj tus thawj coj hauv kev kho dua tshiab, hnub no Alien Skin's Blow Up plugin rau Photoshop zoo tsim nyog saib yog tias kev ua kom tshaj plaws yog ib yam uas koj xav tau. Tshuab tuaj txhawb ntau hom duab hom, xam cov duab qis siab me ntsis. Nws muaj peev xwm los mus hloov cov duab fai fab uas tsis muaj kev sib tw, thiab kev xaiv kom hloov nyob rau hauv qhov chaw, los yog ua ib qho duab tshiab. Lub tshuab siv cov tshuab siv cov nplaim taws thiab simulated film grain los txhim kho cov tsos mob ntawm cov huab cua.
Ntau Software thiab Plug-ins
Cov xwm txheej tshiab tau ua nyob rau hauv cheeb tsam no txhua lub sijhawm thiab nrog ntau tus neeg sim tau tshaj tawm ntawm lawv cov khoom, nws tsis yog yuav qeeb txhua sij hawm sai sai. Rau daim ntawv teev cov khoom lag luam tas li uas tsim tau rau cov duab zoo nkauj, kom mus saib qhov txuas hauv qab no.
