I have to change the size and ppi of an image of my husband in photoshop because he is presenting at a conference. I am supposed to have it to them within the next few hours, and I am stuck! It is currently 5.042w x 7.68h at 72ppi. It is supposed to be 2.5w x 3.5h, 300ppi at 100%. I opened up the photo in PS, and then clicked on "new" so I could make the changes, but when I do that his picture disappears and a white page loads. I am pulling my hair out...any help would be SO GREATLY APPRECIATED!
when I scaled it without changing the cropping my width came out slightly less than 2.5” (without distorting the proportions)
I converted it to a scalable file format then sized to avoid loosing resolution and converted it back to .jpg and .png
You are all so amazing. I was immensely frustrated today in trying to get this completed for my husband. You all stepped up and helped me, and I am incredibly grateful. I love this community, I have been a FReeper for many years.. (10+?) and I am honored to call you my FRiends.
If you ever need help with diet, healthy lifestyle, or alternative health questions, I am your FReeper. I am a registered dietitian, we eat paleo/low carb, I have 50 continuing education credits in herbs/vitamins, and I have been studying vaccine safety and the Pharma Industry for over 30 years. Oh, and I am currently training to be a midwife. PM me if I can help you in any way.
Yeah, the proportion was not initially correct for the final size she wanted. In situations like this I just use the crop tool. Set it for the final settings you want then use the tool.
Agree, but my thought is it’s a head shot for a conference booklet, so that kind of short run job would be run on a color copier rather than offset press.
I just sized it for the largest dimension and let the width be slightly undersized. I did convert it to GIMP’s .xcf file format (scalable) and then exported it into .jpg and .png formats. She e-mailed me the original file and then sent one that was scaled. So I did it twice. Doubt there was any appreciable difference in output quality.
Did you ever use ImageMagic? It is a very powerful command line image processing program. I used it daily for 5-1/2 years.
On one occassion, I resized 40,000 images and thumbnails in one evening with it. Started it some time after 5:30 PM and when I came back to the office about 4:30-5:00 AM it was finished. It took original image sizes and shapes which varied and converted the size and dpi to a standard format for the web.
I maintained color and black and white images for print and different formatted version for the web.
It was absolutely amazing how efficient that was. And it was open source. My niece’s husband works for the Navy, was surprised to find that they use it too.

They have an awesome API. Allowed me to add image processing to my apps with no muss no fuss. I am intimately familiar with their stuff, and it is extremely well written. Tight compact efficient code. No OO BS I would assume. Almost like a master coder did it all in ASM.
Portable Win32 static at 16 bits-per-pixel component. Just copy to your host and run (no installer, no Windows registry entries).
It has versions that mirror my philosophy.
Everything I have ever written is like that. Run it from a flash drive if you want.
I’m not a programmer or a developer. I used it daily for a specific job of maintaining a very large catalog image library for a wholesale distributor. Like you said, incredibly fast, smooth, efficient. If you give it a command, it is executed. Period. If you type wrong, hee hee hee
No, I had little problems with it. If I did it was my logic that was faulty. Learned never to operate with the master data, even with backup.
I also used GREP to extract page number, item number sequences and other data from final .pdf documents. Learned to open them up, remove the offending syntax for 2 numeral 1’s following each other so I could remove the page numbers for each item in the section. Used Pdftk to open it. Again very fast very efficient command line tool, but it simply worked if you wrote the right command.
Also found Gnumeric spreadsheet, the only one I know of that will allow RegX find/replace commands inside the spreadsheet. I loved using it for text editing. Documentation sucked.
The process of creating the catalog was a total dirty hack, but I was very good at making all the moves to get it done.
Did that for 5 years, plugging it into Quark for print and same bullets and data for the web.
Every day I was moving flat files from the AS400 to a Windows PC and often to the Redhat Linux box on the other side of my desk. Eventually I found ports of the necessary software that ran on Windows and used the Linux box less often.
It was a monster.
I’m not a programmer. Took one course back in 1982 when I built my first PC. A few years ago I thought I might play with python. Did not spend the necessary time to do anything useful with that. I understand it is very good for quick one of a kind projects.
Ruby seems to be a bit more sophisticated than Python. Not sure the number of libraries is as large.
But at 69, I doubt I do any programming, hee hee hee.
LOL.... I code for Windoze in a Linux environment. You are like my mirror image dopelganger. Linux is so stable.
I’ve been running some form of Linux since 1994. Started with a UMSDOS version of slackware. No GUI, but it was quick.
Then I used Mandrake, Redhat, Xubuntu and lately Debian. Have been using XFCE GUI since Redhat 8.0 came out. It was not part of the package but I found it and installed it. Amazingly efficient. No bloat. Still using it, have no interest in changing that.
If you do quite a bit of enlarging and reducing, I find Ben Vista Photo Zoom Pro and Alien Skin plug-ins to be far, far better than any of PS's "Image Size" options.
I am SOOOOO sorry. I got called away for work and completely forgot to come back here and check. I hope someone was able to help you.
