Crop lots of images to the same Graphic area

[daisyw11459631]

Don't know if I am missing something

Does anyone know how to crop the same size area of an image area? I have 13 scans of tide chart  showing tide flow every hour  all the same size map with tide info overall  The scans have been done by me all settings the same all at 400DPI  settings I am trying to crop the same size area out of each page  showing just a small area of the charts (Just as if I had cut each image out of the book with scissors! )

I am line up one point up on a graphic point on each of the images ie line mark arrowhead or something in each of the graphics areas don't know if there is a better way to do this? 

With the crop tool, I am setting the size but this is just controlling the aspect of the area I required it as a  fix the size of the crop area you can drag it out to any size area you like.

I can't guarantee the overall scan area of each of the overall page so the overall image size of the border area is different on each scan and as it was book half the scans are upside down and rotated in the scanner program and were not always tight up against the scanner edges.

In this case, I am looking at the size of each of the cropped areas, not resolution.

is there a way to do this? 

I am using CS5 

Thanks

I am not sure what you are describing exactly.

Please post sample images to clarify.

Hi Andrew,

My take on your question is that you need the exact same size crop box on multiple images?

Try using the Rectangular Marquee tool, followed by Edit > Crop. With the Marquee tool selected, you can specify the width and height of the selection in the Options Bar, and you can save the settings with a Tool Preset that will be available in any file.

I have found that tool but the size of the crop is not fixed only the propositions I need to crop to a fixed size as an example an area says 40mm High X 60mm Wide from every one of the original image file! But as you need to drag the crop frame out to a fixed size I am looking to always get a frame size of 60X40 The frame does not appear to be fixed

I wish to end up with 13 images all of the same area of the chart I have been doing this by eye in the past but not that good. Would like a little more control

After that, I am dropping the images into a simple word doc table showing the tide info for that area at a fixed time High Water, HW 1h, HW2h and so on it would be nice if every image was the same area at the same scale

Hope this makes a little more sense

BarbBinder spoke about the

Rectangular Marquee tool

which can be set to a fixed size in pixels.

Use Fixed size as Barb said.

To get mm instead of pixels, just type mm.

(f anyone reads this later, type "in" for inches, etc., for other measurements.)

Hi Andrew:

Using the Marquee tool, you can define a fixed width and height. Select the Marquee tool and choose Style: Fixed Size from the Options Bar at the top. Then save as a Tool Preset. Now you can define the crop area with a single click.

So am I forgetting about the crop tool to do this job! I have found the fixed size within the Marquee tool What is the best way to end up with one cropped image file (at the required size) I assume I just use a copy the area inside the Marquee then paste inside the Marquee it into a new document and save it. I have been trying to use the crop tool to do this job

If this is the case its solved

I think we are now sorted  it was not easy to find the answer I had been trying to use the Crop tool and could not find a way to fix the size

this way looks to work I assume I am just using the marquee tool at a fixed size  the copying paste the selected area into a new blank document and giving the new document a new file name saving all 13 cropped vies in the new file this was not easy to find the information for a very simple problem  it had been driving me nuts!  Help files and Youtube /Videos

Thanks for everyone's help

I can now do this job with a lot more control next time until now I had been doing this job by eye with not very good results!

Thanks for the help re the Marquee tool and crop option my tool for the crop is under Image, not Edit tab is this the same as your copy of the program. I assume this will cut down the original scan I had unless I can save it as a copy beforehand or option 2 is to Copy and paste into a new file as I wish to have the original scans for use at a later time any thoughts on the best plan of action

I will try to decode what you have written and ask that you confirm the following:

1 You have scanned 13 pages from a book.

2. Within each scan is a small specific area, common to all, although the image content is different.

3. The area common to all is of a common magnification.

3. The specific area is not in the same position in all scans.

4. You cannot be assured that each scan area is perfectly horizontal.

5. If asked, you can place two easily seen dots in each scan:

Point A: shows the upper left corner of a desired crop.

Point B: is an A-to-B horizontal alignment reference for the crop so each image may be rotated, if necessary.

If all of the above are correct, it is possible that by using one scan as a Master, you can use the Difference Blending Mode to align all the points of reference --the dots -- and create a common crop of a 13-layered file, and then save each layer as a separate file.

Having had a few replies so far! I think I need to use the Marquee tool set at a fixed size then copy an area inside the marquee and paste into a new image file and save all my cropped images in a new single folder leaving my original scans untouched for use at a later date

I had been trying to use the crop tool to do this job. I do need to keep track of all the images with good naming control but apart from that I think it is solved. I could not find out how to do this thanks for your help

Have you actually read BarbBinder ’s first reply?

After setting the selection you should invoke the menu command Image > Crop.

Another approach might be to use

• File > Scripts > Load Files into Stack

• align the images manually (Edit > Auto-Align Layers might not produce a meaningful result if the differences between the images are too big)

• crop the image (with »Delete Cropped Pixels« unchecked)

• File > Export > Layers to Files
