How can I resize an image in Preview?

There has been lots of discussion about Preview but non really answers my question. If I resize an image and duplicate it the duplicate over rides the settings of the original - so now I have 2 images the same size which is not what I want. I want the new image smaller but to keep the original the same size as before resizing. Versions seem to do the same thing, and as far as I can make out so does export. I know you can revert one of the duplicate images to get it back to the original size but it is a rather convoluted process.
I know there are very clever people here so perhaps one of you can give me a work flow to do what I require. Thanks in advance.

Of course, you can save some steps by duplicating the original file first, and then resize the copy.

How can I resize an image without losing resolution or using the crop tool? I am using Photoshop Elements 13 on a PC.

How can I resize an image without losing resolution or using the crop tool? I am using Photoshop Elements 13 on a PC.

Hi Peru Bob,
I've tried two images, the results were:
Image 1
Jpg, original file size 923KB, dimensions 848px x 279px.
After resizing to 848px x 180px with 72dpi, the file size decreased to 164KB.
Image 2
Jpg, original file size 809KB, dimensions 1200px x 1800px.
After resizing to 668px x 722px with 72dpi, the file size decreased to 307KB.
So, there seems to be a fair file size loss - is this to be expected?

You asked about changing the file size
To change the size in Pixels, you use the options at Size in the export dialogue

Hi
   I got a reference for the same question from Stack Overflow http://stackoverflow.com/questions/14726485/resize-an-image-resource-in-cq5/16728970#16728 970
I tried the same method
Resource resourceNew = resource.getResourceResolver().getResource(img.getFileReference());
    Asset asset = resourceNew.adaptTo(Asset.class);
    log.error("asset ****" + asset);
    Layer layer = new Layer(asset.getOriginal().getStream());
    layer.resize(200, 200);
    log.error("layer ****" + layer);
                        Image image = new Image(resource);
    String mimeType = image.getMimeType();
    ByteArrayOutputStream bout = null;
    ByteArrayInputStream bin = null;
    try {
        bout = new ByteArrayOutputStream(2048);
        layer.write(mimeType, 1, bout);
        bin = new ByteArrayInputStream(bout.toByteArray());
        asset.addRendition("resizedImage", bin, mimeType);
log.error("asset Bin" + asset);
    } finally {
        // close streams ...
Where img is my Image object and I was able to create a rendition in the dam.
But the rendition I am getting is in File format. Is there a way by which i can change it to png format??? any Help will be appreciable..
Thanks

How can I resize an image in the header?

I have uploaded my organization's logo into our document, but it is out of proportion to the rest of the document. I've delted it and uploaded smaller versions of the logo and it is still too big. How can I format the image in the header so that it is more reasonably sized?

Thanks. The triangle was buried in the image. If you hadn’t told me where to look, I would never have found it!

How can i resize my image after image trace?

Hello all!
I'm just now getting into using illustrator (currently on trial for illustrator cc) and I've taken a couple of my illustrations and attempted to use the image trace. The only way I can seem to get the image trace to actually produce an accurate trace is if I use a very large file size. So I take my scanned image (600 dpi 2000x 1891) and load it into illustrator, and here's where the problem comes in. Illustrator will not show my entire image on the screen. I zoom out as far as I can go and it's still cutting off the bottom and top of the image. When I try to scale the image it won't let me scale it down to even 90%.
So my question, is there anyway I can load my full size image into illustrator, image trace it, and then scale it down so I can see the whole image on my screen? It's very hard to paint and work around the image when it's getting cut off.
The first picture is what the whole picture looks like, but it's such a small file size it's blurry and won't image trace correctly.
The 2nd image is what happens when I load my full image size in, I'm scrolled as high as the page will go and the top is still cut off.

Hope this helps Trevor.
There are other ways of doing this, but try this one.
Menu - ‘Select all’
Object - ‘transform’ - ‘scale’
Dialogue box - click ‘uniform’ add number 1% to 100%, your choice
Options - tick ‘scale stroke & effects’
tick ‘preview’ to see results

How can I edit lightroom 5 smart previews on mac book pro (mbp) when the lightroom 5 master image files are on my external hard drive is disconnected from the mbp

How can I edit lightroom 5 smart previews on mac book pro (mbp) when the lightroom 5 master image files are on my external hard drive is disconnected from the mbp? So far when I try to disconnect the external HD from the mbp, I get the following pop up window: The disk "external hard drive A" couldn't be ejected because "Lightroom" is using it. Quit that application and try to eject this disk again. When I do that and restart Lightroom 5, the Adobe Photoshop Lightroom - Select Catalog screen pops up but doesn't list my external hard drive A as a choice.
I've reviewed Adobe's Lightroom Help | Smart Previews Lightroom 5 web page and still haven't been able to figure what I'm doing wrong. Any help would be appreciated.

Your internal HDD. by default, is named 'Macintosh HD'. From what information you supplied, it looks like there is already a Lightroom catalog installed on you local (internal) HDD using the standard naming convention Adobe uses as well as a Lightroom catalog on your external drive which you created. To be sure of which catalog Lightroom is loading when it starts up, To do this, start Lightroom as you normally would. After it starts, select the Lightroom menu item, then select the Catalog Preferences item and finally, navigate to the General tab. The Location information will tell you exactly what catalog Lightroom is opening by default. This will likely be the Photography Mac Book Pro Versions catalog on your external HDD. Once that is confirmed, you are ready to proceed. As an additional test/verification, you can shut down Lightroom and, this time, start Lightroom while holding down the ALT/OPTION key. This will cause Lightroom to pause and display a screen which will allow you to chose a different catalog to open. Navigate to the /Users/[user name]/Pictures/Lightroom folder and select the Lightroom 5 Catalog.lrcat file. When Lightroom comes up, there should be no previews or folders as this catalog should be empty. Now you can be certain which catalog is being used and which catalog has all your data and you are ready to migrate your current catalog. Shut down Lightroom.
To migrate your current catalog, use Finder to locate your Photography Mac Book Pro Versions folder on your external drive. Select the folder and select COPY from the context menu. Next, use Finder to navigate to the /Users/[user name]/Pictures/Lightroom folder on you internal HDD. You can start at the Macintosh HD level and work your way down by opening each level (Macintosh HD/Users/[user name]/Pictures). Select the /Pictures folder and then select PASTE... from the context menu. When the COPY/PASTE is complete, you should see the following files on the Macintosh HD:
Macintosh HD/Users/[user name]/Pictures/Lightroom/ and
Macintosh HD/Users/[user name]/Pictures/Photography Mac Book Pro Versions
The Macintosh HD/Users/[user name]/Pictures/Lightroom folder will contain the empty default catalog the Adobe created when Lightroom was installed and Macintosh HD/Users/[user name]/Pictures/Photography Mac Book Pro Versions will contain a copy of the catalog you created on your external HDD.
You are almost done now. Make sure your external drive is still attached for this step. Restart Lightroom using the ALT/OPTION key again. When the Select Catalog screen appears, select the Choose a Different Catalog button (lower left side). When you do, a Finder window will open to allow you to navigate to a catalog of your choosing. Navigate to Macintosh HD/Users/[user name]/Pictures/Photography Mac Book Pro Versions and select the file Photography Mac Book Pro Version.lrcat. This is the copy you just created. Select the Open button and Lightroom should start. You should see all of your previews and settings just as before. Also, in the left hand panel, all of your folder should show up and none of them should be dimmed and none of your previews should display a small exclamation point badge. Either a dimmed folder name or an exclamation point badge indicates that Lightroom can't find the associated image file. If everything looks good, go to the Lightroom menu, select Preferences and then select the General tab. Under Default Catalog, select an option to either load the LAST catalog opened or select the Users/[user name]/Pictures/Photography Mac Book Pro Versions catalog from the drop down. Shut down Lightroom and then restart it normally. This time, when Lightroom starts, you should be viewing the new copy of your catalog. You can confirm this by looking at the General tab on the Catalog Preferences screen (Lightroom/Catalog Preferences menu items). Shut down Lightroom once again and this time, eject your external drive before restarting. This time, your folders in the left hand panel will be dimmed but you should be able to work with your smart previews. If Lightroom should display a Select Catalog screen with the external drive detached, double check your settings as it indicates Lightroom is still looking at the copy of the catalog on the external drive rather than the new copy you made.
Finally, if you are seeing dimmed folders and/or exclamation point badges with the external drive attached, this indicates a problem. You can select any folder and select Update Folder Location from the context menu. This will allow you to navigate to the copy on the external drive and select it. Lightroom will then update the catalog (select to synchronize the content). This will not only clear the dimmed folder problem but also remove the exclamation point badges for all photos in that missing folder. However, it may indicate that not all went well with the copy of the catalog so make sure to verify all went well. You can use the Get Info option on the two folders. You should see the same number of files/folders for both the copy on the internal drive as well as on the external drive but you can't rely on the byte count because of the possibility of differences between the geometry of the two drives. Hope this all helps!

How can i control what images load on my project to save preload time and avoid loading all images, elements, divs not yet visible?

Sup buddies,
How can I control what images load on my project to save preload time and avoid loading all images, elements, divs not yet visible?
As the project grows in size the load time increases. How does one control not loading all images ,divs,elements etc. until they're
needed on the timeline? For example some sections are off and only become visible when recalled. My projects slowly grow in size so loading
all images , is counter productive . My other option would be to create separate htmls but that breaks the seamless user experience .
TY...Over N Out...

hello, kiwi
quote: "Is there an easy way to burn a completed project to DVD, but keep only the (lo res, lo size) previews on my hard drive?"
yes.
maybe,...
1. you might think of making DVD backups first prior to importing the photos into Aperture. "Store Files: In their current location" once in Aperture make low rez Previews, and export finished Project.
or,
2. bring in the photographs to hard drive first prior to importing the photos into Aperture. "Store Files: In their current location" once in Aperture make low rez Previews, and export finished Project.
the low rez Previews will stay in Aperture but the high quality Versions will be exported onto DVDs and gone from the hard drive (if you delete the originals).
another way would be to export small about 50-70 pixel wide high quality jpegs to a folder on your Desktop and import & keep these in Aperture Library as a reference. make metadata to show where the original Project DVDs are stored and DVD filing system used.

How can I resize partition? - New larger hard drive installed

Hello,
The hard drive on my MacBook Pro recently died on me (just past my Apple Care warranty - lucky me). I sent it to an authorised reseller/repair place and they installed a new hard drive for me - replacing my old 250GB with a nice new 500GB. The problem is when they copied over the disk image from my previous hard drive they did not scale up the image (yeah, not so happy bout that). Now I find myself with a 500GB hard drive with a 250GB partition called Macintosh HD and 250GB of unused/unusable space. On top of that I'm just starting to get messages saying boot disk nearly full. How can I resize the "Macintosh HD" partition to use the entire disk? I've tried using disk utility, clicking on the main drive, going to the partition tab and dragging the Macintosh HD partition to use the entire disk but after a few seconds of a message saying "waiting for disk to reappear" it returns to the same 250GB size. Running OSX 10.9.3. Any suggestions?
Thanks all!

See the tips in pounding's section on using Disk Utility:http://pondini.org/OSX/Home.html and you could also take the route of buying an external hard drive (a great idea of maintaining a backup), format that drive for Mac OS X Extended (Journaled), clone the startup disk to that drive, then boot from the external, erase and format the internal, then clone the external back to the internal partitioned as you want.

How do I resize an image within a drop zone (not the drop zone itself) in motion 5?

How do I resize an image within a drop zone (not the drop zone itself) in motion 5?

I think others would be able to help if you describe a little more why you'd like to do this. Given that drop zones are a way of passing images into Motion that you want to manipulate, resizing a drop zone is the equivalent of resizing the image.
If you're having a problem with an image from Final Cut being too big or too small, select the Drop Zone in the inspector and make sure the Fit parameter is set to 'Fit' - 'Center' will result in images dropped not being scaled to fit the Drop Zone. 'Stretch' will force the dropped image to fill the space defined by the drop zone,
If the image is already cropped and scaled up in Final Cut Pro, that is the information that Motion gets - you can't scale down the image to see more of the edges that have been cropped off.
If you want more than one copy of the image passed via the drop zone, use Make Clone Layer from the Object menu.

How can I save an image I have created in Pages as a jpeg?

How can I save an image I have created in Pages as a jpeg? The image has both a photo and various text boxes. I would like to use it in one of the Photocard websites but they only accept jpeg. Any easy solutions please.

Hold command shift 4 and draw a box around what you want and then click again, on your desktop a .png file will appear.
To convert it to jpeg, open it in Preview and Save as.
if you want all your screenshots to be jpg, download the free Tinkertool and make the change.

I updated to Photoshop cc 2014 and now can't resize the images like I used to.
I used to click on the image and then go to the corner hold down shift and resize it. Now it won't do it.
How do I do it now?
I have a project deadline and need to do this asap. Panicking that I won't meet my deadline.

Did you turn off the "show transform controls" option in the move tool?
It sounds like you were using that previously.
And you can always transform by using the Free Transform command (command/control T).

How can I put an image onto a postcard format?

How can I put an image onto a postcard format?

By postcard format do you mean crop the picture into a postcard shape?
If so, here is one way: Activate the Rectangular Marque tool. Set Style to Fixed Aspect Ratio, and enter the dimensions for Width & Height. In this example I used a standard postcard size of 6" x 4.25". Open your picture, draw out the rectangle, and Image > Crop. The picture will now be in the 6 x 4.25 proportion.
To get it to the actual 6" x 4.25" size, do Image > Resize > Image Size. Check the Constrain Proportions Box, and enter either the true Width or Height; the other dimension will change accordingly.
If this is not what you are trying to do, please be more specific.
