Software :: Method To Batch Resize Photos With Options
Feb 6, 2010
I've been using GNU/Linux for many years, and am finally taking steps to reduce Windows to a gaming platform only. One important category is photography. I've used the GIMP a lot and have been quietly browsing several photo apps for various tasks; they've really progressed in recent years. There is almost too much choice! On Windows I used XnView as my image viewer and for simple manipulations, but for batch JPG resizing I found Irfanview hard to beat. It has an intuitive interface for options, of which the following have become musts:
-Resize longest side, maintaining aspect ratio
-Specify the exact number of pixels
-Select a useful algorithm (usually cubic)
-Set JPG compression
-Process subdirectories recursively
-Write processed files to a new location, preserving subdirectory structure
-Confirm error-free operation or list errors
- A nice-to-have is visual feedback of progress during processing.
Up till now, the main purpose of this has been to downsize the ~3MB JPG images my digital camera makes for fast viewing-viewing images 640 pixels max side length instead of 3504 pixels, I can browse more efficiently, and watch my life in fast-forward, so to speak. So now I am moving everything to be done on Debian, and want to downsize my 80-GB collection to an intermediate resolution for my wife to work with. I'd like her to use a photo management app instead of doing everything by hand.
I could of course use Irfanview for the job and then copy everything to a *nix partition, but that's sort of not the point. I know the heavily promoted Imagemagick can do batch conversion efficiently and is used as a backend for a lot of apps, but I'm not sure whether it can preserve subdirectory structure; this is a must because of over 200 subdirectories. The mogrify command changes the original image, and it seems inefficient to copy 80 GB only to downsize it.
I'm sure that read-resize-write can be done preserving directory structure by using a script, and I'd be willing to do that in the future, but for now I lack experience and am not willing to use a script I don't understand. Otherwise, there seem to be few free apps that do batch resizing with the features above. I looked into Phatch, but it doesn't seem to let me set the exact resolution I want. I don't want to use Picasa until Google makes it free. Gwenview does batch resize, but doesn't seem to give all the options, unless I missed something.
I have an external drive with lots of photos on. I want to resize them and someone suggested using Code: for f in *.jpg; do convert "$f" -resize 640x480 -strip -quality 86 "$f"; done Then I realised I don't know how to cd to an external drive. The drive shows up as "Iomega HDD" in Nautilus. I tried every variation I could think of including creating a mount point on my home partition.
Ladies and gentlemen, I announce my 1st Qt4 application - Baires. Baires is a program that helps you easily resize bunch of pictures from one directory and place it to the same or another, with just one click (after initial setup, of course). With help of @microchip8, who built spec, RPMs and placed them to his repositories, I have now made an "official" download page at my site.
So I have a partition I wanna make smaller. I can use GParted but this is not secure. Even with backup - there are tons of personal files, I can't check 'em all if they are correct after resizing. So I thought maybe I can create a dir on another machine and do something like Code: cp -a / /mnt/0 # which is a mounted directory on another machine and after repartitioning HDD get everithing back this way. Will it work?
Installed a test system and I messed up. I let the installer use the entire 200gb for F12 install when I only wanted to use 100gb. Since it is test and new install I could just blow it away and start over but decided to use this as a learning opportunity. I chose all the defaults on the install so my partition is ext4. Since the partition I want to resize is in use while the system is up, I need to do this offline.
I have read a bit and it looks like there are couple of methods I could use. I have an install DVD and a Live CD so I could use either. If I could use a GUI that would be nice but I do not know how to access that if there is one. I have already booted to the Live CD and figured out how to access the command line tools (resize2fs and lvm) although I have not figured out how to use them yet.
I recently installed 11.04 and Unity 2D (because my old laptop can't run the full 3D version). So far I'm pretty impressed and its growing on me, despite the negative press I'd heard and my own skepticism of change going into the new UI.
One thing that I haven't been able find out is if there is an option to vertically resize the launcher based on the number of active icons. I only have about half a dozen icons pinned to the launcher permanently, so there's a lot of blank "dead space" on the bottom half of the launcher unless I have a zillion other things open simultaneously.
Is there a way to make the Unity 2D launcher automatically shrink upwards to fit the number of pinned icons + active applications? (I've attached a mock up of the sort of feature I'm talking about.) It would be fantastic if there was a way to do this because it would be a much cleaner and more efficient use of my screen space. I've already downloaded the Unity 2D Settings application, but there are only 5 or so things you can edit with that little app. I was hoping for a method with a bit more flexibility.
I've heard that Unity 2D is specifically designed NOT to use Compiz, so things like cube desktop and wobbly windows will never be available in this 2D desktop environment. (Sadface for losing out on the eye candy I used to have in 10.10 )
I am trying to perform a hard drive installation of RHEL 5.5. I specify the installation method and the partition and directory holding the ISO image in /etc/grub.conf
Code:
However, I am still presented with the "Installation Method" and "Select Partition" screens when anaconda runs. Is the syntax of the repo boot option correct?
So I have the burned ubuntu CD, and I'm attempting to install it on a system that has one HDD with XP/Vista on it, and another that is completely formatted and unpartitioned. However, when I boot to the ubuntu CD, I can use the menus from the bottom, and select the language when initially prompted, but I can't select any of the menu options except for boot from first hard drive.
I have no problem with Firefox or thunderbird and open office. All my photos have been downloaded onto the new system no bother. I am now trying to download photos from C-D and most have done so very well but!!!I have had a problem with UDF.
I'm running GNOME on Fedora 11. My daughter is shortly due to take possession of a digital SLR camera - a Canon EOS 400D. Apparently it comes with a USB cable. I know very little of photography, or of image stuff on Linux, so I have a few questions: Will I be able to connect it to my Linux box and import the images? Is gthumb-importer the appropriate application for this? Is there better? Are the images jpegs, or something else? I only need to copy the images to the laptop and to be able to view them - I don't need to edit them or any such.
I'm running F14, and i'm having an annoying issue - I can't upload photos to facebook. I have flash player installed, but when i hit the button to create an album in facebook, it tells me i need to install flash. I use opera, but the problem also exists when i try firefox. However, i'm running ubuntu on my netbook, also with opera, and here it works just fine.
My aspire 4745 laptop has a in-built webcam, so i installed Cheese to use it. Cheese starts and the webcam works at first instance. But it doesnot shows any thumbnails for taken pictures nor it saves any picture (I have checked everywhere for the images, inside and beyond my home folder). I am lost - if the wen cam can take a picture, why cannot save it?
Hey I've got firefox and google chrome installed. I was using firefox for school and had to watch a photographed tour for history. The photos would not show up at all but in chrome they came up fine. There was a video b4 the photos came up so idk if firefox coudnt view the photos or the video but I've got all the plugins
I have ubuntu on one laptop and arch linux on another. Ubuntu allows me to easily take photos from my camera and put them on my laptop. Arch does not, even after I've installed the "necessary" software.
What is it that ubuntu has that allows me to do this? I'd like to know, so that I can install it on arch.
upload photos to Photobox (other than one by one)? It keeps telling me I haven't got the plugins, offers me 2 but both are installed. FTP can't be used as they say (log in and drop stuff in). I have Mint Helena (Karmic Koala) and Mozilla 3.6.8
I'm trying to batch rename 3,300 photos, and can't figure it out.
I've tried digiKam and KRename, however I can't figure out how to simply rename the files as such:
~/Pictures/[year]/[month]/[datetime].JPG
where the year, month, and datetime are when the picture was taken, via EXIF data. In digiKam, I can't figure out how to rename the files to move to a different dirrectory than their current one, and with KRename, I can't figure out how to only use the year for the directory instead of the entire datetime.
Does anybody have an idea why I can't upload photos to Facebook?Always when I try to do it, both in Firefox and in Opera the message "The connection has been reset" appears... What could be the reason? Could it also be a problem with my router or provider? Because I presume the problem exists, since I have moved flat.
I use: Ubuntu 11.04 (with Unity) Chrome (and also tried using Firefox and Opera) My Problem? Today I tried to upload some pictures on Facebook (like I use to) and after choosing them it gets stuck, the browser works, but the pictures don't get uploaded. I tried different browsers and the results were the same. My java package seems to be up-to-date as well as my browser (Chrome). I don't really know what is going wrong.
I'm learning how to use F-Spot photo manager. When I click on an image thumbnail in the main browse box, (to highlight it), and then I click the "Edit Image" button at the top, - it doesn't display the image in the edit box. It displays a default grey picture frame (place holder)
I've got a lot of photos I've take over the years, and I suspect I've got lots and lots of duplicates, since I may have multiple backups for the same photos.
Have anyone experience with deduplication of photos in Ubuntu, and could recommend an approach for a quick and efficient way to do this?
I am using Ubuntu 9.10 and I am unable to upload photos into my Myspace Page. I an app on my Myspace Page and I am unable to view my dressing room in my super pets app. I get the same results from my super pets app as I do when I try to upload photos. Although the stuff is there, I get an empty box. What do I need to do to be able to open my photos from my space and actually see my pictures there and not an empty box?? or open my super pets app and see my stuff there and not an empty box ?
Is there un-delete software for Fedora? On my windows computer I have a program for un-deleting camera photos, it comes in handy for un-deleting the photos that my girlfriend makes me delete.
I own Fedora Core 12 and an HP scanner. I want to make digital copies of all the pictures I took a few years ago. I have a lot so I tried scanning five at a time thinking I could cut and paste into smaller images like with MS Paint on Windows. HPLIP 3.9.12 wouldn't let me modify the scans so I tried GIMP 2.6.10. GIMP 2.6.10 is a nightmare! When I opened my scan of five pictures I had trouble opening a new image. Then I had to specify the size of the new image. The when I cut and pasted I couldn't rotate. Then when I figured out how to rotate my image was too small.
Then I tried scanning just one picture but HPLIP left a lot of blank space. I tried cropping out the blank space with GIMP but the image size was the same with the blank space. I don't want to post photos to Flickr that are mostly empty space.I wish I could show you examples but the forum won't let me post them.Any ideas or suggestions for a program for Fedora Core 12 that's got the functions and features of MS Paint?
I started using gtkpod with my iPod not long ago, and I like it a lot.But I have one problem, the images in my photo libraries stretch to fit the screen, making them a lot more ugly than they should be.Is there any way to fix this?
I've installed Silkypix (tried 2.0 and 3.0SE) through Winedoors in Linux Mint Helena and keep getting coloured stripes across the photos. It actually works if I ignore these stripes but I wonder if it could be fixed...? I also tried Linux raw converters Rawtherapee and UFRAW but they don't seem as good, especially the noise reduction function. Can I fix Silkypix or is there another Linux software that is comparable?
