Scaling Images

[SeanBender]

Have a question on scaling in perspective or in differnt "planes"

I've attahced an example. We know what the door is since we did the vynil on the door but the customer wants to put up some arithecial letters above the door. So I just used the sidewalk and brick as a reference. But is there any other way to determine scale in 3d? or even if the picture was slanted in a way?

I hope this is making sense.

It's not.

Best thing to do would be to Measure the space above the doors.

I would take the photo as you did, straight on. Measure distance between the columns and count the brick then count the same amount out on the column for the height? That should get you very, very close to actual size. I don't feel like there's going to be enough slant to make a difference. Maybe I don't understand exactly what you are asking?

 

[Gino]

Call them on the phone, talk to someone who can count and read a ruler and nicely ask them to measure it, since you're too lazy to do it.

I never trust my customer's measurements.
One recently said the sign was about "four or five feet wide". I went to check it out and it was 8 feet.

 

[Snydo]

It should be about 192" wide by 33.5" to the bottom of the gable vent if those are standard 8"x2.25" red bricks.

When you say "ABOVE THE DOOR" are you referring to the gable face?

You have to scale using a reference at the surface that is being used, so count the bricks
A standard US brick size is 8 inches long x 3 5/8 inches wide (depth) x 2 1/4 inches high.

Get a spike by ike. It's fantastic, but you have to use the device when taking the picture, and it costs $500. But, it'll take an angled photo, measure the distance with a laser, and distort the photo to be as if you were facing the structure directly, from vertical center.
Here's a before and after, one distorted and one for dimensions:

I can help you... what exactly are the measurements for the door? WxH

Cripes, I didn't even read that he had door dimensions. Don't do it for him!
Sean, draw a rectangle over the doors, resize it to your known dimensions, look at the percentage difference that it has changed, then select the image and enter that percentage. (This works in coreldraw swimmingly, but I can't attest to illy or mspaint)

 

[Boudica]

Too late... How about if I don't explain the method to my madness?
Although, you kinda just did, but you didn't mention everything.

 

[Stacey K]

Well, once again, I didn't read the post well enough. I though you meant you were putting architectural letters on the brick above the doors LOL I didn't know arithecial was a word - what the hell kind of letters are those?

I don't know that it is a word... but I chose a font that made me feel... Arithecial.

Why convert it down to 1/10?
Oh, I see I'm not in myront's corel thread, I'll see myself out.

But really, in corel, once you draw a perfect shape over an image that hasn't been resized, your rectangle and image both are technically 100%. By altering the size of the rectangle, it will alter the percentage, which is the exact ratio the image needs to be changed to. Now, thanks to you, we won't see Sean again until this same thing comes up!

1/10th - because I didn't want a file that would be too large to upload here. For something this size I would normally do it at 100%.

I will build templates at 1/10 when they are this size though:

Shoulda used a spike on that crooked monstrosity! I, like every corelfanboy, much prefer full scale always, even on something like this:

 

[Boudica]

IDK what a spike is. Is this better?

Didn't you see post #9?

I would love to see a sign in real life that was lettered with "Copy to be determined".
