System; Linux Mint Cinnamon 18.3 ImageMagick 6.8.9-9 Q16 x86_64 2018-09-28 I believe this maintains EXIF for a .tif -> .tif -define tiff:exif-properties=true Question 1; Is it possible to Keep all Exif from a 'convert' for; 1) .jpg -> .tif 2) .tif -> .jpg Question 2; Is it possible to maintain all ...

Understood, thanks snibgo.

Similarly, detecting software transformations like skewing or perspective distortions is not possible from such a small low-quality JPEG.

What size/dpi would one need to analyze software transformations like skewing or perspective distortions ?

Regards.

Correct snibgo,

I am wondering if IM has the ability to determine #1-3 without metadata, I should have mentioned that.

Hello. Is Image Magick able to extract the; 1. Lens focal length in mm used to take the photo 2. Determine if a cropped or full frame sensor was used in the photo ? e.g. 1.6x, 1.5x 3. Determine if the photo was cropped or skewed with a Tilt-Shift lens, or in software ? For Example: https://imagizer ...

Whoa snibgo !

Dizzy, I am.

Genius plan. Way beyond my basic wrapping textures around an image using displacement maps.

Hats off to you just the same.

Take good care, thanks again.

Fred, nothing is bothering, I am beyond words for your professional assistance in providing choices to save lots of time by automating.

It's a beautiful result.

You have helped far beyond my expectations, I'm grateful.

Best regards.

All the best to you.

[Solved]

2nd thought, never mind the last post on stitching two images, seems far fetched. Your first correction before the barrel distortion to correct perspective looks so good. Is IM able to apply the barrel correction to the bottom part of the image (sidewalk and below) or does it have to be applied to ...

OK, will do Fred. Many thanks again.

I noticed some tearing on the upper left and right sides of your last example, is that expected or avoidable ?

Cheers

Wow, that's really great Fred ! Thank you so much. To confirm... 1. Both examples are keeping the original size of the typed words ? 2. In #2, what is your recomended method to auto crop to the original size: 2659x3353 -> 2519x3245, keeping the resulting deskew content centered ? 3. If I wished to ...

Thank you very much for your expertise. I had another question that popped up. In a similar fashion to how panorama stitching software works... Could the straightened sidewalk of your 2nd barrel correction image be merged with your 1st perspective correction, e.g. sidewalk and below from image 2 ...

Thank you for your attention snigbo and fmw42.

In the #2 example I uploaded: https://imageshack.com/a/img921/4414/RDdmSi.png
can IM automatically fill the resulting white areas after the deskew, with the same color as the original edge ?

OK, 1. Here is an original: Document-Skewed_Before_IM.png 2519x3245 pixels @ 300 dpi https://imageshack.com/a/img924/9350/gwXqy6.png 2. After deskew IM: Document-Skewed_After_IM.png https://imageshack.com/a/img921/4414/RDdmSi.png 2659x3353 @ 300 dpi convert Document-Skewed_Before_IM.png -deskew 80 ...

Brilliant ! I tried to emulate your code; convert 002-10-Exterior-Front.jpg -distort barrel 0,0,0.04 -distort Perspective 0,0,0,0,639,0,639,0,55,307,55,307,572,314,572,314,0,380,0,425,637,425,637,425 hillouse.png Looks good, except there is tearing on the right side... https://imageshack.com/a ...

snibgo, I'm seriously impressed at what you did, would you please allow me a curious request..., this is a beautiful result but is it possible to correct the distortion of the downward bend in the sidewalks to be a little more straight ? I'll consider rebuilding the House on flat land if you will ...

I am trying to achieve whatever output size the original is. This is an example of skewed document text; https://www.codeproject.com/KB/graphics/1045825/ex3.png The simplest use; convert <image> -filter catrom -deskew 80% +repage <result> It works, deskews... but the resulting size is changed to ...
