jpegtran performs various useful transformations of JPEG files. It can translate the coded representation from one variant of JPEG to another, for example from baseline JPEG to progressive JPEG or vice versa. It can also perform some rearrangements of the image data, for example turning an image from landscape to portrait format by rotation.\njpegtran works by rearranging the compressed data (DCT coefficients), without ever fully decoding the image. Therefore, its transformations are lossless: there is no image degradation at all, which would not be true if you used djpeg followed by cjpeg to accomplish the same conversion. But by the same token, jpegtran cannot perform lossy operations such as changing the image quality.\njpegtran reads the named JPEG/JFIF file, or the standard input if no file is named, and produces a JPEG/JFIF file on the standard output.
Maelezo ya mchapishaji (Kiingereza)
jpegtran ni nini?
jpegtran ni programu ya chanzo huria ya Windows kutoka Independent JPEG Group.
Usakinishaji na mahitaji
Kuna visakinishi rasmi kwa CPU yoyote katika muundo wa Portable. Inafanya kazi bila kusakinishwa (portable).
Umaarufu na aina za faili
Kifurushi chake cha Chocolatey kimepakuliwa mara 4,805.
Faida / Hasara
Faida
- Chanzo huria: mtu yeyote anaweza kukagua na kujenga msimbo
- Portable: inafanya kazi bila kusakinishwa
Hasara
- Kiungo rasmi cha kupakua hakikujibu wakati wa ukaguzi wa mwisho
Kwa ufupi: jpegtran ni zana ya chanzo huria ya Windows kwa kompyuta za CPU yoyote.
Je, ni salama kupakua jpegtran?
- Faili inatolewa na jpegclub.org, kikoa cha mchapishaji mwenyewe
- Kiungo cha kupakua kinatumia HTTPS
- Hashi ya SHA256 imechapishwa, hivyo unaweza kuthibitisha faili:

- Msimbo chanzo uko wazi kwa umma
- ExeAtlas haihifadhi, haifungi wala haibadilishi visakinishi

Maswali yanayoulizwa mara kwa mara
Je, jpegtran ni bure?
Ndiyo. jpegtran ni programu ya chanzo huria chini ya leseni ya Open Source.
Je, ni salama kupakua jpegtran?
Faili inapakuliwa kutoka jpegclub.org, ambayo ni ya mchapishaji mwenyewe; ExeAtlas haihifadhi wala haibadilishi faili. Linganisha hashi yake ya SHA256 na ile iliyoonyeshwa hapa, au fungua ripoti ya VirusTotal ya hashi hiyo.
Jinsi ya kusakinisha jpegtran kwa winget?
Fungua PowerShell au Windows Terminal na uendeshe amri ya winget iliyoonyeshwa kwenye ukurasa huu. winget hupakua kisakinishi rasmi na kukagua hashi yake ya SHA256 kabla ya kukiendesha.
Je, jpegtran inafanya kazi kwenye ARM (Windows on Arm)?
Kisakinishi hakitegemei usanifu wa kichakataji.
Je, jpegtran inaweza kutumika bila haki za msimamizi?
Ndiyo, ni portable: fungua kumbukumbu (archive) na uiendeshe.
