pdf creation of the SAME SIZE of two pdf files

Hotwheels 222,

It might help to think that PDF is a container that can have many things such as texts, photos, graphics, vector elements, etc. all wrapped up in it.

Normally, the content is created in another application such as InDesign, Illustrator, MS Word or many other applications. In the application you create a blank document and add or place images, type text in any font you want to place or create some elements of vector (if the application has actually vector tools)and even other multimedia such as audio and video as long as the application supports,

Photos can all have a different resolution, vector elements have no resolution (I'll explain), the text can be in many different fonts, and they all keep their distinct characteristics within the PDF file.

A PDF file created from an application like Photoshop will be just a resolution, because the PS is a pixel in the image editor and a PS document can have only one resolution.

.. .the idea that two adobe products cannot communicate Acrobat to photoshop in terms of a resolution of pdf in photoshop seems very awkward... Once again, as a PDF file may have a lot of pictures with different resolutions, even if the PS could get this info (which may not) what PS resolution would decide to use? PS sheets it is up to the user to decide based on what they want their final production can be.

You mention a document you have this "seems no inserted images" and "it appears as if there is an image"?

The pdf of the cover are you referring?  The PDF producer is "Adobe Acrobat Image Conversion plug-in 10.0" is a tip out of 'Test Name screen' and thought it came from Photoshop.

While possible, this document was created entirely in Photoshop, it is also likely that it was created in another application such as InDesign, exported from here in PDF and then PDF etc. was opened in Photoshop that rasterizes the content and flattened into an image file with the resolution you have chosen when opening in PS and then saved as just an image in PDF format. The graphic designer who created this probably did this because they did not want to give you a print quality PDF that you can try to extract the elements of.

You mentioned that you thought that the doc was in Adobe Illustrator (AI) HAVE is primarily a tool for creating vector allowing also to the pixel for inclusion based raster images (with a resolution of specific pixels) to be included in a document of AI if wanted.  Strictly speaking, vector objects do not have a resolution. They are based on mathematics,

He said essentially, put a point to such & such X, coordinated, now, put an another punch to another X, Y coordinates, it takes account of the arc or angle between the two points and said to draw a straight line, or draw a curved line, etc. Since it is only the mathematical instructions. This can be as large as you want and the relationship between the 2 points and the arc of the curve or line will dictate how the extended line or curve will be redrawn enlarged.

Vectors are 'independent of the resolution' you can draw a vector logo to 1 x 1 inches and enlarge it to 50 x 50 inches or even as important as a home and it will always print crisp and clean. Notice, that this applies only to vector content in your document; pixel content is blocked in the resolution, it was created in the.

To inspect the elements in a PDF document using the object Inspector in Acrobat Pro. Since a PDF file can contain several different objects, you have to click exactly on each object to get information about the selected object. So if you had 10 photos in your PDF you must select each in turn and he would give you the size in pixels, resolution, color space and profile, etc if you have clicked on the text, it will identify the police. It is well named, an Inspector of the object rather than a Document Inspector. Try it yourself with the different PDF files that you may encounter. If for example, it gives you the exact same info (resolution, pixel dimensions etc.) bit matter when you click, then you're probably dealing with a simple image. If you get the dimension in different pixels, resolutions when you click in different areas, you're dealing with a PDF file that had separated the distinct elements.

I don't see why I shouldn't be able to get a document that is located at 17.7 x 22.9 to 72 dpi up to one that is 8 x 11 at 300 ppi.

In Photoshop, go to the Image, the Image Size menu. This will show the dimensions in pixels (width & height) at the top. If you don't interpolate (resample) Photoshop can only put the same number of pixels in different size documents. When you press it same number of pixels in a smaller resolution doc increases. When you place the same number of pixels in a larger doc and the resolution fails.

Don't forget, that the resolution is PPI (Pixels Per Inch). If you do the math it starts to make sense.

Below notes that each dialog box features the same EXACT pixel dimensions.

In the first box, it shows the 1275 x 1650 pixels in a document of 17.708 22.917 x inches. This gives a resolution of 72 DPI.

In the second box, I changed the size of the document to 8.5 x 11 inches and pixels of 1275 x 1650 even now increase the resolution to 150 DPI.

In the third box, I changed the resolution to 300 DPI and the pixels of 1275 x 1650 even now decrease the size of the document to 4.25 x 5.5 inches.

If you check the resampling, Photoshop will interpolate (resample) image to throw the pixels, or adding pixels, but there is no magic involved and the results are never as good as we could hope.

Like Goldilocks and the 3 bears, some things are better when they are 'fair '.
