Markaa waxaad ka soo dejisay sawirro qaar ka mid ah kamaradaada quruxda badan ee Canon ama Nikon ? Hagaag^(Well) , u diyaari sawirro waaweyn oo leh xallin badan! Waxaad ka hadlaysaa 20+ megapixels iyo qaraaro aad u sarreeya! Qiimaha mar walba hoos ayuu u dhacayaa tayada mar walbana kor ayay u kacaysaa. Dadka intooda badan, waa xad-dhaaf.

Intaa waxaa dheer, mararka qaarkood way adag tahay in la maareeyo dhammaan tayadaas dheeraadka ah xagga cabbirka, kaydinta iyo la wadaagga sawirradaada kuwa kale. Dabcan, haddii aad isticmaasho adeeg sida Google Photos , waxaad ku dhejin kartaa dhammaan sawiradaada qaraarkooda hooyo oo aad la wadaagi kartaa albamka kuwa kale habkaas, adigoo ka gudbaya baahida loo qabo in la yareeyo sawiradaada.

Si kastaba ha ahaatee, waxaa jira waqtiyo aad u baahan doonto inaad hoos u dhigto sawirka, sida ku dhejinta mareegaha ama gelista dukumeenti Word ah ama bandhigga PowerPoint . Ku darista xal buuxa ma bixinayso faa'iido dheeraad ah waxayna kaliya hoos u dhigi doontaa boggaaga internetka ama waxay ka dhigi doontaa dukumeenti Word ama PowerPoint mid weyn.^(PowerPoint)

Ku cabir Sawirka Daaqadaha

Daaqadaha^(Windows) , waxaan jeclahay in aan isticmaalo Rinjiga^(Paint) . Haddii aadan u baahnayn inaad cabbirto boqollaal sawir, markaa Rinjigu^(Paint) si fiican buu u shaqeeyaa. Ku fur Rinjiga^(Paint) sawirka oo waxaad arki doontaa badhanka cabbirka^(Resize) ee ribbon.

Guji^(Click) taas oo waxaad ku beddeli kartaa boqolkiiba ama pixels. Waxaad sidoo kale si toos ah u ilaalin kartaa saamiga dhinaca iyo in kale.

Haddii aad rabto barnaamij yar oo fancier ah oo loogu talagalay cabbirka sawirada, waxaad isticmaali kartaa barnaamij la yiraahdo Gimp . Waa lacag la'aan waxayna haysataa qalab fiican oo lagu cabbiro sawirada. Waxaad ka soo dejisan kartaa halkan:

https://www.gimp.org/

Marka aad rakibto, fur sawirkaaga ka dibna dhagsii Sawirka^(Image) iyo Miisaanka^{( Scale Image)} .

Ogsoonow in Gimp 2.8 , waxaad isku dari kartaa dhammaan daaqadaha hal daaqad halkii aad wax walba ku dul sabeyn lahayd meel kasta. Waxaad taas samayn kartaa adiga oo aadaya Windows oo gujinaya Hal Daaqadda Mode^{(Single Window Mode)} .

Haddii habkan aad u fududaato in lagula shaqeeyo. Si kastaba^(Anyway) ha ahaatee , mar alla markii uu soo muuqdo wada hadalka sawirka cabbirka, waxaad arki doontaa dhawr doorasho:

Waxaad si toos ah u beddeli kartaa cabbirka sawirka adiga oo hagaajinaya ballaca iyo dhererka. Tani waa habka ugu badan ee lagu cabbiro sawirka. Waxa kale oo aad hagaajin kartaa xallinta, kaas oo kuu ogolaanaya inaad ku aragto sawirka cabbirkiisa asalka ah ee internetka, laakiin hoos u dhig tayada daabacaadda. Xallinta meel bannaan ee inta badan shaashaduhu waxay muujin karaan 72 ama 100 ( PPI ama pixels/in). Tani waxay ka dhigan tahay inaad hoos u dhigi karto xallinta 72 ama 100 ppi iyada oo aan wax farqi ah laga dareemin sawirka shaashadda kombiyuutarka waxayna hoos u dhigi doontaa cabbirka sawirkaaga si weyn.

Ogsoonow in xalka ugu badan ee shaashadaha kumbuyuutarka dhowr sano ka hor uu ahaa 1024×768. Xitaa haddii aad qaadato qaraar sare sida 1600 × 1200, waxaad weli hoos u dhigi kartaa ballaca sawiradan dhabta ah ee ka hooseeya 1000 pixels oo weli waxay qaadan doontaa shaashadda oo dhan.

Sidoo kale ogow in marka la beddelayo ballaca ama dhererka, saamiga dhinaca waxa lagu hayn doonaa si toos ah. Haddii aad gujiso silsiladda yar ee midigta, waxay "kala saari doontaa" ka dibna waxaad bedeli kartaa ballaca ama dhererka si madaxbannaan, taas oo fidin doonta sawirkaaga. Haddii aadan rabin in ay fidiso, markaa waa inaad gooysaa sawirka, taas oo ah nooca la isku qurxiyo, laakiin maaha mid la mid ah tan iyo markaad ka saarayso qaybo ka mid ah sawirka. Marka la isku miiro, sawirka oo dhan mar walba waa la ilaaliyaa.

Ugu dambeyntii, waxaad dooran kartaa habka Interpolation , kaas oo go'aaminaya tayada miisaanka. Sida caadiga ah, waxa loo dejiyay Cubic . Halkan waxaa ah farqiga u dhexeeya xulashooyinka kala duwan:

Midna^(None) - Midabka pixel waxaa go'aamiya deriska ugu dhow ee sawirka. Waa habka ugu dhaqsiyaha badan, laakiin waxay keeni kartaa sawir aan dhab ahayn.

Linear - Midabka pixel waxaa lagu go'aamiyaa celceliska midabka afarta pixels ee ugu dhow sawirka. Tani waxay sawirku ka dhigeysaa mid ka fudud doorashadii hore.

Cubic - Midabka pixel waxaa lagu go'aamiyaa celceliska midabka siddeedda pixels ee ugu dhow sawirka. Si aad ah isku mid, laakiin mar labaad, sawirka hoos loo dhigay ayaa fudud oo doorashadani waxay siin doontaa natiijada ugu fiican.

Sinc (Lanczos3) - Habkani wuxuu isticmaalaa qaacido xisaabeed oo loo yaqaan Sinc wuxuuna sameeyaa isdhexgalka tayada sare leh.

Taasi waxay ku saabsan tahay in sawirada lagu miisaamo Windows^(Windows) .

Hoos u qiyaas sawirka OS X

Haddii aad rabto inaad cabbirto sawirka OS X , uma baahnid inaad ku rakibto wax software dheeraad ah. Waxaad isticmaali kartaa gudaha barnaamijka Horudhac^(Preview) . Markaad furto sawirkaaga, dhagsii Tools ka dibna Hagaajin Xajmiga^{(Adjust Size)} .

Tani waxay kor u qaadi doontaa cabbirka hagaajinta wada-hadalka halkaasoo aad si qurux badan u leedahay xulashooyin la mid ah sidii aan kugu tusay GIMP :

Waxaad hagaajin kartaa ballaca iyo dhererka oo aad bedeli kartaa xallinta sidoo kale haddii aad rabto. Waxay sidoo kale kuu sheegaysaa waxa cabbirka natiijada noqon doono ka hor inta aanad dhab ahaantii samayn isbeddelka, taas oo fiican.

Hoos u qiyaas sawirka iOS

Haddii aad ka shaqaynayso iPhone-kaaga ama iPad-kaaga oo aad rabto hab degdeg ah oo aad hoos ugu dhigi karto sawirka cabbir gaar ah, waxaad isku dayi kartaa barnaamij bilaash ah oo la yiraahdo cabbirka sawirka^{(Image Size)} . Waxay u muuqataa in shaqada loo qabtay dadka intooda badan.

Waxaa xusid mudan in app-ka sawirada caadiga ah ee iOS^(Photos) uu hadda samayn karo xoogaa miisaan fudud ah, laakiin kaliya leh xulashooyinka hore loo sii diyaariyay. Taabo sawirka ka dibna taabo Edit dhanka sare ee midig. Dhowr astaamood oo yaryar ayaa ka soo muuqda dhanka hoose ee shaashadda. Horey u soco oo ku dhufo astaanta wareegta/ dalagga ee bidixda fog.

Marka xigta, waxaad arki doontaa calaamad cusub oo ka soo muuqanaysa wax yar oo ka sarreeya midigta fog. Astaantan waxaa loogu talagalay beddelka cabbirka sawirka.

Hadda waxaad heli doontaa inaad ka doorato jaangooyooyin la sii dajiyay. Tan waxa ku jira labajibbaaran, 2:3, 3:5, 3:4, iwm.

Dadka intooda badan, tani way ku filnaan doontaa haddii ay rabaan inay ku dhejiyaan Instagram , iwm., markaa run ahaantii uma baahnid app.

Hoosta Sawirka Android

Ugu dambeyntii, yeynan iloobin isticmaalayaasha Android . Sawirka & Sawirka Resizer^{(Photo & Picture Resizer)} waa app bilaash ah kaas oo kuu ogolaanaya inaad hagaajiso cabbirka iyo tayada sawirka.

Taasi waxay ku saabsan tahay! Waxaan rajeyneynaa^(Hopefully) , in ay daboosho nidaamyada hawlgalka ee ugu caansan iyo aaladaha ay dadku isticmaali doonaan si ay u cabbiraan sawirada. Wax su'aalo ah ama faallooyin ah? Halkan ku dheji. Ku raaxayso!

Scale Down an Image in Windows, Mac, iOS, and Android

So you just downloaded some pictures from уour new fancy Canon оr Nikon camera? Well, get ready for some huge piсtures with lots of resolution! You’re talking abоut 20+ megapixels and extremely high resolutions! The prices are always coming down and the quality is always going up. For most people, it’s overkill.

Additionally, it’s sometimes hard to manage all that extra quality in terms of size, storing and sharing your pictures with others. Of course, if you use a service like Google Photos, you can upload all your photos in their native resolution and share albums with others that way, bypassing the need to scale down your images.

However, there are times when you will need to scale an image down, such as putting it up on a website or inserting it into a Word document or PowerPoint presentation. Adding it at full resolution will provide no additional benefit and will only slow down your webpage or make your Word or PowerPoint document huge.

Scale Down Image in Windows

For Windows, I like to use Paint. If you don’t need to resize hundreds of photos, then Paint works just fine. Open Paint with the photo and you’ll see a Resize button in the ribbon.

Click on that and you can resize by percentage or by pixels. You can also automatically maintain the aspect ratio or not.

If you want a little fancier program for resizing images, you can use a program called the Gimp. It’s free and it has some nice tools for scaling images. You can download it here:

https://www.gimp.org/

Once you have it installed, open your image and then click on Image and Scale Image.

Note that in Gimp 2.8, you can combine all the windows into a single window instead of everything floating around all over the place. You can do that by going to Windows and clicking on Single Window Mode.

If find this way easier to work with. Anyway, once the scale image dialog appears, you’ll see a couple of options:

You can change the image size directly by adjusting the width and the height. This is the most common way to scale an image. You can also adjust the resolution, which will allow you to view the image in its original size online, but reduce the print quality. The spatial resolution most screens can show is 72 or 100 (PPI or pixels/in). This means you can reduce the resolution to 72 or 100 ppi without any noticeable difference in the image on a computer screen and it will reduce your image size significantly.

Note that the most common resolution for computer screens a couple of years ago was 1024×768. Even if you take a higher resolution like 1600×1200, you can still reduce the width of these really huge images under 1000 pixels and still it will take up the entire screen.

Also note that when changing the width or height, the aspect ratio will be maintained by default. If you click on the little chain to the right, it will “unlink” and you can then change the width or the height independently, which will stretch your image. If you don’t want it to stretch, then you have to crop the image, which is kind of like scaling, but not the same since you’re removing parts of the image. When scaling, the whole image is always maintained.

Lastly, you can choose the Interpolation method, which determines the quality of the scaling. By default, it’s set to Cubic. Here is the difference between the different options:

None – The color of a pixel is determined by its closest neighbor in the picture. It’s the fastest method, but can result in a coarse image.

Linear – The color of a pixel is determined by the average color of the four closest pixels in the picture. This makes the picture look smoother than the previous option.

Cubic – The color of a pixel is determined by the average color of the eight closest pixels in the picture. Pretty much the same, but again, the scaled down image is smoother and this option will give the best result.

Sinc (Lanczos3) – This method uses a mathematical formula called Sinc and does a high quality interpolation.

That’s about it for scaling images in Windows.

Scale Down Image in OS X

If you want to scale an image in OS X, you don’t have to install any additional software. You can use the built-in Preview program. When you open your image, click on Tools and then Adjust Size.

This will bring up the size adjust dialog where you pretty much have the same options as I showed you in GIMP:

You can adjust the width and height and change the resolution also if you like. It also tells you what the resulting size will be before you actually make the change, which is nice.

Scale Down Image in iOS

If you are working from your iPhone or iPad and want a quick way to scale down an image to a specific size, you can try out a free program called Image Size. It seems to get the job done for most people.

It’s worth noting that the default Photos app in iOS can now do some simple scaling, but only with preset options. Tap on the photo and then tap on Edit at the top right. A few small icons appear at the bottom of the screen. Go ahead and tap on the rotate/crop icon at the far left.

Next, you will see a new icon appear a little higher up at the far right. This icon is for changing the dimensions of the photo.

Now you’ll get to choose from a set of preset ratios. This includes square, 2:3, 3:5, 3:4, etc.

For most people, this will be enough if they just want to post to Instagram, etc., so you really don’t need an app.

Scale Down Image in Android

Lastly, let’s not forget about those Android users. Photo & Picture Resizer is a free app that lets you adjust the size and quality of an image.

That’s about it! Hopefully, that covers the most common operating systems and platforms that people will use to scale images. Any questions or comments? Post them here. Enjoy!
