If you’ve ever inserted an aerial photo or an old scanned site plan into LayOut, you might have wanted to give it a specific scale on the page. My favorite technique for doing this uses the Clipping Mask feature.
Choose File > Insert… to insert a raster image into your LayOut document. Find a known measurement somewhere on your image. This known measurement can be anything: a scale bar (if you’re lucky); the length of a fence or sidewalk; or even the roofline of a building. It’s important that you find something that’s relatively large and that whose length you already know. You’ll use this portion of the image as a “benchmark” to size the entire image to a specific scale.
Figure out what scale you’d like to give your inserted image. Keep in mind how the scale will impact the size of the image and how that image will fit on your page.
Create a rectangle around the “benchmark” portion of your image. Use the Rectangle tool to do this, and make sure it has no fill (so that you can see through it.)
Select both your rectangle and your image and choose Edit > Create Clipping Mask. Select the resulting crop and give it a visible stroke so you can see its boundary.
Somewhere on your page, use the Line tool to draw a line whose length corresponds to the scale of the image you’re working on.
To draw a line, click to start drawing, move your cursor in the direction you want the line to go, type the length you want and hit Enter.
Move your benchmark, snapping its lower-left corner to the left endpoint of your line. Be sure that Object Snap (Arrange > Object Snap) is turned on, or snapping won’t work properly.
Scale your benchmark so that it’s the same length as the line. With your benchmark selected, hold down the Shift key and scale it until it snaps to the right endpoint of your line. As long as you hold down Shift, your selection should scale proportionately.
Select the benchmark and choose Edit > Release Clipping Mask. Delete the rectangle from Step 3, and the line you drew in Step 5, and you’re done. Voilà! You’ve set your image to a specific scale.
This may seem like a lot of steps but it’s actually pretty simple. Have a look at the following silent movie to see how it’s done.
Kama umewahi kuingizwa picha ya angani au mpango wa zamani scanned tovuti katika LayOut, unaweza kuwa alitaka kutoa kiwango maalum juu ya ukurasa. Mbinu yangu favorite kwa kufanya hivyo hutumia kipengele cha Clipping Mask. Chagua faili > Kuingiza... kuingiza raster picha katika hati yako LayOut. Tafuta kipimo kinachojulikana mahali fulani kwenye picha yako. Kipimo hiki kinachojulikana kinaweza kuwa chochote: bar ya kiwango (ikiwa una bahati); urefu wa uzio au kijia; au hata mstari wa paa la jengo. Ni muhimu kwamba upate kitu ambacho ni kikubwa kwa kulinganisha na ambacho urefu wake unajua tayari. Utatumia sehemu hii ya picha kama " benchmark " ukubwa picha nzima kwa kiwango maalum. Kujua nini kiwango ungependa kutoa picha yako iliyoingizwa. Kumbuka jinsi kiwango cha picha kinavyoathiri ukubwa wa picha na jinsi picha hiyo itafaa kwenye ukurasa wako. Kuunda mstatili kuzunguka <unk>benchmark<unk> sehemu ya picha yako. Kutumia chombo Rectangle kufanya hili, na kuhakikisha haina kujaza (kwa hivyo unaweza kuona kupitia yake.) Chagua wote mstatili wako na picha yako na kuchagua Hariri > Kuunda Clipping Mask. Chagua mazao yanayotokana na kuipa stroke inayoonekana ili uweze kuona mpaka wake. Mahali fulani kwenye ukurasa wako, tumia chombo cha Mstari kuchora mstari ambao urefu unafanana na kiwango cha picha unayofanya kazi juu yake. Ili kuchora mstari, bonyeza kuanza kuchora, kuhamisha cursor yako katika mwelekeo unataka mstari kwenda, type urefu unataka na hit Enter. Hatua ya mstari wako wa msingi, snap kona yake ya chini ya kushoto kwa mwisho wa kushoto wa mstari wako. Hakikisha kwamba Object Snap (Arrange > Object Snap) ni kugeuzwa juu, au snapping si kazi vizuri. Scale benchmark yako hivyo kwamba ni urefu sawa na mstari. Baada ya benchmark yako kuchaguliwa, kushikilia chini Shift ufunguo na kiwango chake mpaka snaps kwa mwisho wa haki ya mstari wako. Maadamu kushikilia chini Shift, uteuzi wako lazima kiwango kwa usawa. Chagua benchmark na kuchagua Hariri > Release Clipping Mask. Kuondoa mstatili kutoka Hatua ya 3, na mstari wewe kuchora katika Hatua ya 5, na wewe ni kufanyika. Hebu tuone! Umeweka picha yako kwa kiwango maalum. Hii inaweza kuonekana kama hatua nyingi lakini ni kweli pretty rahisi. Angalia filamu ifuatayo ya kimya ili uone jinsi inavyofanywa.
