JPEG, TIFF, PSD, BMP, PICT, PNG, uye GIF yakatsanangurwa
Wakavhiringidzika pamusoro peiipi mafirimu maitiro ekushandisa apo, kana unoshamisika kuti misiyano yakadini iripo pakati peJPEG , TIFF, PSD, BMP, PICT, uye PNG?
Heano mamwe mazano akawandisa:
- Kana mifananidzo yacho yakagadzirwa kuWebhu kana kushambadzira, shandisa JPEG , PNG, kana GIF.
- Kana zvifananidzo zvingaonekwa mune zvinyorwa zvakashandurwa, shandisa TIFF.
- Kana iwe uchida kuchengeta shanduko inoramba ichishandurwa, sarudza software yako yekuzvarwa fomu yefaira . dzakadaro .PSD ye Photoshop,
Heino tsanangudzo pfupi yemafaira akafanana eefaira mafaira, ane zvikwata zvekutevera mamwe mashoko:
Nguva Yokushandisa JPEG
Joint Photographic Experts Group (JPEG kana JPG) yakanakisisa kumifananidzo kana uchida kuchengetedza firiji duku uye usakanganise kusiya imwe humwe hukuru hwekuderedza kukuru kwehukuru. Ko faira yacho inodukuka sei? JPEG inowanzoonekwa se "kurasika". Nemashoko akajeka, apo faira re JPEG rakasikwa iyo compressor inotarisa chifananidzo, inoratidza nzvimbo dzemavara akafanana uye dzinoshandisa iyo panzvimbo. Iyo yakasvibiswa ndiyo mivara isingaonekwi seinojairika "yakarashika," saka huwandu hwemashoko emuvara mumufananidzo unoderedza izvo zvinoderedzawo faira yefaira.
Apo JPG file yakasikwa iwe unowanzobvunzwa kugadzirisa kukosha kwehutano hwakadai sePhotohop Image zvingasarudzwa izvo zvinokosha kubva kune 0 kusvika ku12. Chinhu chiri pasi pe5 chinogona kunge chichikonzera chifananidzo chinoputika nokuti huwandu hwehuwandu hwemashoko huri kukandwa kunze kuderedza faira refaira. Chinhu chipi zvacho pakati pe8 ne12 chinotaridzirwa semuitiro wakanakisisa.
JPEG haikodzeri zvifananidzo zvine mavara, mazamu makuru emaronda, kana maumbirwo akareruka nokuti mitsetse yakashata ichasvibisa uye mavara anogona kuchinja. JPEG chete inopa zvasarudzo zveBaseline, Baseline Optimized, kana Progressive.
- Baseline (Standard) - Iyi fomu yeJPEG inozivikanwa nevose vewebhu.
- Baseline Yakagadziriswa - Iyi sarudzo yeJPEG yakasarudza inopa mararamiro akaenzana uye kunyanya kuderedzwa kwakanyanya. Inotsigirwa navashambadzi vese vemazuva ano asi yakanga isingatsigwi neyo yekutanga yeWeb browser. Ndiyo sarudzo yako yakanakisisa yeJPEG mafaira nhasi.
- Kufambira mberi - Kunogadzira JPEG file iyo inoratidza zvishoma nezvishoma sezvo ichikotora, kutanga kuvhara, uye zvishoma nezvishoma kujekesa sezvo ichikanganwa. Hazviiti kuti chifananidzo chiwedzere chero chipi zvacho, asi chinogona kupa chinyararire chekukurumidza sezvo chifananidzo che blocky chiri kutakurwa pakarepo pakushamwaridzana kunonoka. Nehuwandu hwevashandisi veIndaneti pa-high-speed connections nhasi, Progressive JPEG haigoni kushandiswa.
Nguva Yokushandisa TIFF
TIFF (Tagged Image File Format) yakanaka kune chero ipi zvayo ye bitmap (pixel-based) mifananidzo yakagadzirirwa kudhindwa nokuti iyi fomu inoshandisa CMYK ruvara. TIFF inobereka mafaira makuru nekuda kwesarudzo yakafanana ye 300 ppi isina kurasikirwa kwehutano. TIFF inodzivirirawo mavara, alpha kusvikika, uye zvimwe zvinhu zvakakosha paunoponeswa kubva ku Photoshop. Rudzi rwehumwe ruzivo rwakachengetedzwa nemafaira eTIFF akasiyana nemao e-Photoshop versions, saka bvunza rubatsiro rweWhohophop kuti uwane mamwe mashoko.
Nguva Yokushandisa PSD
PSD ndeyekuVhopphop yakarongwa. Shandisa PSD apo unoda kuchengetedza zvidimbu, kusvibhenekera, matanho ekugadzirisa, masikisi, kudonha nzira, michina yepamusoro, kuenzanisa maitiro, vector mavara, uye maumbirwo, nezvimwewo. Ramba uchiyeuka, zvinyorwa izvi zvinogona kuzarurirwa mu Photoshop kunyange zvazvo vamwe vashanduri vemafananidzo ichavhura.
Nguva Yokushandisa BMP
Shandisa BMP chero ipi zvayo ye bitmap (pixel-based) mifananidzo. BMPs dzakakura mafaira, asi hapana kurasikirwa muhutano. BMP haina maturo chaiwo pamusoro peTIFF, kunze kwekuti unogona kuishandisa kweWindows wallpaper. Kutaura zvazviri, BMP imwe yezvigadzirwa zvemufananidzo izvo zvakasara kubva pamazuva ekutanga emakombiyuta mapikicha uye hazviwanzoiti, kana zvichishandiswa, nhasi. Izvi zvinotsanangura kuti sei dzimwe nguva inonzi "fomu yefa".
Nguva yekushandisa PICT
PICT ndeyekare, Mac-only bitmap format yakashandiswa pakushandura Quickdraw, Sezvakaita BMP yeWindows, PICT haisiwanzoshandiswa mazuva ano.
Nguva Yokushandisa PNG
Shandisa PNG apo unoda zviduku zviduku zvakakura pasina kurasikirwa muhutano. PNG mafaira anowanzova maduku pane TIFF mifananidzo. PNG inotsigirawo ruzivo rweAlfi (mitsindo yakadzika) uye yakagadzirirwa kuva yejw.org kushandurwa kweGIF. Cherechedza kuti kana iwe uchida kuramba uine pachena , iwe uchada kuchengeta faira yako yePNG sePNG-24 uye kwete PNG-8. PNG-8 inobatsira pakuderedza faira yeiyo mafaira ePNG apo iwe haufaniri kujekesa, asi ine mararamiro akafanana pamapareti asviki seGIF mafaira .
Iyo PNG format inowanzoshandiswa chaizvo pakuumba mifananidzo yePhones nePads. Ingoziva zvifananidzo hazvipi zvese zvinonyatsoita pk format. Chikonzero icho png isisina kurasikirwa maitiro, zvinoreva kuti zvishoma kwazvo kana kushandiswa kunoshandiswa pamufananidzo wepng unoita kuti mafayela akakura zvakakura kupfuura ivo .jpg cousins.
Nguva Yokushandisa GIF
Shandisa GIF yeWebhu yega yega yega ine mavara-256- mavara. GIF mafaira nguva dzose anoderedzwa kusvika 256 mavara akasiyana-siyana kana kuti akaderera uye anoita zviduku zvikuru, kutsvaga-kutakura mifananidzo yeWebhu . GIF yakakura kune mabhii eWebhu, marati kana mifananidzo, katuni-kufanana nemifananidzo, mabhendi, uye misoro. GIF inoshandiswa zvakare pamifananidzo duku, compact Web. GIF haifaniri kushandiswa kushandiswa kumifananidzo kunyange pane kudzoka kweGIF mifananidzo uye GIF Mifananidzo yekusimudzira kwekusimudzirwa kwemafambisi uye ezvehupfumi.
