Peb txhua tus yeej paub dab tsi lub scale. Qhov no piv linear nyob rau hauv lub loj ntawm cov pa graphical sawv cev ntawm qhov tseeb qhov tseem ceeb ntawm cov duab khoom. Hais tias yog, nws yog ib lub observance ntawm tej yam proportions thaum lub sij hawm ntawm daim ntawv thov tej duab los yog cov duab editing duab.

Yuav ua li cas yog lub scale, thiab yog vim li cas koj xav tau nws

Xws li ib tug qauv ntawm cov kis tau tus mob ntawm daim duab siv nyob rau hauv kiag li txhua yam los ntawm maps thiab drawings thiab xaus nrog lub li ib txwm cov duab. Tab sis hais tias yog cia li tsis tau rau cov me nyuam cov yam duab nyob rau hauv tag nrho cov loj. Nyob rau hauv cov ntaub ntawv no, los txog rau cov kev pab thiab cov scale. Ua tsaug rau nws ib tug duab yuav raug txo los yog nce, thaum saib qhov tsim nyog proportions uas yog qhia nyob rau hauv cov duab. Yuav ua li cas yog lub scale peb twb paub, thiaj li cia tus tham txog ob hom ntawm nws.

zoom scaling

Qhov no hom yog siv nyob rau hauv rooj plaub qhov twg cov duab lub neej-loj ho me dua nyob rau hauv cov duab. Nyob rau hauv cov ntaub ntawv no, nyob rau hauv ib lub thawv qhia proportions muab duab (2: 1, 8: 1, 16: 1, 150: 1, thiab thiaj li nyob). Proportions yuav tsum tau to taub raws li nram no: txoj cai daim duab qhia tau hais tias tag nrho cov duab yuav tsum tau muab faib mus rau hauv centimeters (e.g., 1 cm), thiab rau sab laug - yuav ua li cas muaj ntau zaus tus kwv yog txo los ntawm 1 centimeter nqus duab. Uas yog, yog hais tias peb muaj txoj kev xaiv 2: 1, nws txhais tau tias 1 centimeter kab nqus ntog 0.5 centimeter kwv.

zoom tawm

Qhov no hom yog siv nyob rau hauv rooj plaub yog tias tus kwv hais tias koj xav mus qhia, ntau tshaj ntawm daim duab qhov ntev. Nyob rau hauv ib tug tshwj xeeb kem proportions, peb qhia kom meej yuav ua li cas muaj ntau zaus cov kwv yog ntau dua qhov duab (piv txwv li, 1: 2, 1: 250, 1: 1000 thiab thiaj li nyob). Rau sab laug daim duab qhia tias pes tsawg centimeters duab yuav tsum tau muab faib (e.g., 1 cm), thiab muaj txoj cai - raws li ntsuas units nyiaj rau 1 centimeter. Piv txwv li, peb muaj ib daim ntawv qhia uas qhia tus scale of 1: 2,000,000, saib, qhov no txhais tau tias 1 centimeter card nyiaj 2,000,000 centimeter cheeb tsam (los yog 20,000 meters, los yog 20 kilometers ib 1 centimeter).

Yuav ua li cas rau resize duab

Heev yooj yim mus nrog qhov kev npaj ntawm maps los yog kos duab, tab sis hais tias yog dab tsi lub scale ntawm cov duab, yog heev yooj yim to taub. Tej dluab muaj ntau ntsuas tsis, namely tus daws teeb meem, uas yog nyob rau hauv lub xov tooj ntawm pixels nyob rau hauv cov duab. Scaling dluab, koj yuav tsum them sai sai mus rau tus xov tooj ntawm pixels, rau ho ua lub luaj li cas ntawm daim duab nrog ib tug me me muaj pes tsawg tus ntawm pixels, peb deteriorate nws zoo thiab vice versa. Muaj ntau ntau yam kev pab cuam uas yuav siv tau los siv cov kev ua hauj lwm, cov duab zoo yuav tuaj. Lawv txoj ntsiab cai ntawm cov lag luam yog ua raws li ua pes tsawg tus pixels nyob rau hauv ib tug muab daim duab, li no ua kev daws teeb meem, i.e. qhov luaj li cas ntawm cov tswv cuab cov duab. Tej kev pab cuam muaj peev xwm yuav nrhiav tau nyob rau hauv tshwj xeeb khw muag khoom noj los yog downloaded ntawm lub Internet, tab sis nws yog ib qhov zoo tshaj plaws yuav muaj ntawv pov thawj log, thiab tsis tau download tau pirated cov ntawv luam ntawm cov uas tej zaum yuav thuam qhov kev kawm ntawm koj lub computer thiab ua rau nws tsis yooj yim sua rau cov txheej txheem rau cov duab rau nws.
