Haddii aad u baahan tahay inaad sawir ka beddesho qaab aad u beddesho mid kale waxaad isticmaali kartaa GIMP si aad sidaas u sameyso, laakiin waxaa jira hab sahlan. Waxaad isticmaali kartaa ImageMagick , kaas oo bixiya hab loogu beddelo sawirada adoo isticmaalaya khadka taliska.

Ku rakibida ImageMagick

ImageMagick mar hore ayaa la rakibay. Waxaad ka hubin kartaa Maareeyaha Xidhmada Synaptic^{(Synaptic Package Manager)} . Dooro Administration | Synaptic Package Manager ka socda liiska nidaamka^(System) .

Sanduuqa wax ka beddelka degdega ah ee raadinta ee daaqada ^{(Quick search)}Maamulaha Xidhmada Synaptic^{(Synaptic Package Manager)} , geli imagemagick . Natiijooyinka raadinta waxay bilaabaan inay soo baxaan markaad qorto ereyga raadinta. Haddii ImageMagick mar hore la rakibay, sanduuqa calaamadda ee ku xiga magaca barnaamijka ayaa lagu buuxin doonaa cagaar, waxaadna u gudbi kartaa Beddelka Sawirka Isticmaalka ImageMagick^{(Converting an Image Using ImageMagick)} qaybta hoose.

Haddii ImageMagick aan horay loo rakibin, dhagsii sanduuqa calaamadaynta si aad u furto liiska soo baxay. Ka dooro calaamadda Rakibaadda^{(Mark for Installation)} ikhtiyaarka ah ee liiska.

Falaadh jaale ah ayaa ka muuqata sanduuqa calaamadaynta ee ku xiga imagemagick , taasoo muujinaysa in loo calaamadeeyay in la rakibo. Guji badhanka Codso^(Apply) si aad u sii waddo rakibidda.

Shaashadda Kooban^(Summary) ayaa soo bandhigaysa liiska dhammaan isbeddellada la samayn doono. Guji badhanka Codso .^(Apply)

Horumarka rakibaadda ayaa muujinaya.

Isbeddellada lagu dabaqay^{(Changes applied)} sanduuqa wada-hadalka ayaa soo bandhigaya marka rakibiddu dhammaato. Guji badhanka^(Close) xidh

Ka dooro Jooji^(Quit) liiska Faylka^(File) si aad u xidho Maareeyaha Xidhmada Synaptic^{(Synaptic Package Manager)} .

Beddelidda Sawirka Iyadoo la adeegsanayo ImageMagick^{(Using ImageMagick)}

Marka ImageMagick la rakibo, si fudud u isticmaal amarka beddelka daaqadda terminalka. Tusaale ahaan, amarka soo socdaa wuxuu u rogi doonaa faylka PNG faylka JPEG .

$ convert sample.png sample.jpg

Si kastaba ha noqotee, u beddelashada sawirka JPEG waxay u huraysaa tayada sawirka cabbirka faylka. Waxaa jira beddelka amarka, -quality , kaasoo kuu oggolaanaya inaad qeexdo tayada faylka .jpg ee ka dhashay. ^(.jpg)Waxaad dejin kartaa qiimaha u dhexeeya 0 (tayada ugu liidata) ilaa 100 (tayada ugu sareysa). Xusuusnow in tayada wanaagsan (lambarka sareeyo), uu weyn yahay cabbirka faylka. Guud ahaan^(Generally) , qiimaha u dhexeeya 60 iyo 80 ayaa ku filan inta badan isticmaalka.

Amarka soo socda wuxuu u rogaa sample.png sawir JPEG ah oo leh tayada 80 .

$ convert –quality 80 sample.png sample.jpg

Faylka JPEG ee loo yaqaan sample.jpg waxa lagu dhex abuuray tusaha la midka ah faylka asalka ah ee png . Waxaa jirta hab degdeg ah oo lagu eego sawirka la beddelay. Muuqaalka muuqaalka caadiga ah ee Ubuntu waxaa loo yaqaan Eye of Gnome . Isticmaalka Eye of Gnome , waxaad si dhakhso ah u arki kartaa sawirada soo socda: ani, bmp, gif, ico, jpeg, pcx, png, pnm, ras, svg, tga, tiff, wbmp, xbm , iyo xpm .

Si aad u socodsiiso Eye of Gnome khadka taliska, si fudud u qor eog . Haddaba, si aad u aragto faylka sawirka la beddelay ku qor amarka soo socda:

$ eog sample.jpg

Daawade ayaa furaya isagoo muujinaya sawirka la cayimay.

Si loo xiro Eye of Gnome , dooro Xir^(Close) ka menu -ka faylka .^(File)

Haddii aad doorbidayso isticmaalka khadka taliska si aad u qabato hawlaha, dhagsii halkan^(here) si aad u gasho bog shabakad ah oo bixisa tusaaleyaal isticmaalaya ImageMagick oo ka socda khadka taliska. Ku raaxayso!

Convert Images Between Formats via the Command Line in Ubuntu

If yoυ need to convert an image frоm one format to another you can uѕe GIMP to do so, but there is an easier way. You can use ImageMagick, which provides a way to convert images using the command line.

Installing ImageMagick

ImageMagick may already be installed. You can check in the Synaptic Package Manager. Select Administration | Synaptic Package Manager from the System menu.

In the Quick search edit box on the Synaptic Package Manager window, enter imagemagick. The results of the search start to display as you type your search term. If ImageMagick is already installed, the check box next to the program name will be filled in green, and you can skip to the Converting an Image Using ImageMagick section below.

If ImageMagick is not already installed, click on the check box to open a pop-up menu. Select the Mark for Installation option from the menu.

A yellow arrow displays over the check box next to imagemagick, indicating it is marked for installation. Click the Apply button to continue with the installation.

A Summary screen displays listing all the changes that will be made. Click the Apply button.

The installation progress displays.

The Changes applied dialog box displays when the installation is finished. Click the Close button.

Select Quit from the File menu to close the Synaptic Package Manager.

Converting an Image Using ImageMagick

Once ImageMagick is installed, simply use the convert command in a terminal window. For example, the following command will convert a PNG file to a JPEG file.

$ convert sample.png sample.jpg

However, converting an image into a JPEG sacrifices image quality for file size. There is a command switch, –quality, that allows you to specify the quality of the resulting .jpg file. You can set a value between 0 (poorest quality) to 100 (highest quality). Remember that the better the quality (the higher the number), the bigger the file size. Generally, a value between 60 and 80 is good enough for most uses.

The following command converts sample.png into a JPEG image with a quality of 80.

$ convert –quality 80 sample.png sample.jpg

A JPEG file called sample.jpg is created in the same directory as the original .png file. There is a quick way to view the converted image. The default image viewer in Ubuntu is called Eye of Gnome. Using Eye of Gnome, you can quickly view the following images: ani, bmp, gif, ico, jpeg, pcx, png, pnm, ras, svg, tga, tiff, wbmp, xbm, and xpm.

To run Eye of Gnome from the command line, simply type eog. So, to view the converted image file type the following command:

$ eog sample.jpg

The viewer opens displaying the specified image.

To close Eye of Gnome, select Close from the File menu.

If you prefer using the command line to perform tasks, click here to access a web page that provides a set of examples using ImageMagick from the command line. Enjoy!
