How to Resize a picture

hi
I am using web cam acquiring image using lab view. i want to reduce the size of the picture before saving it .currently the size of the iamge is 300*200. i want to save it in smaller size becaz iwill be displaying this image on mobile and that require small pictures.any idea how to do it in labview.

Attached is a VI which resizes a 2D array (7.0) . It was designed to resize pictures and for pictures of your size it should be fast enough. I don't think webcams use 24 bit color, so you may have to make some modifications. Also, it doesn't do any "clever" stuff like averaging color values. It just takes some of the elements from the original, which seems to be good enough.
From what I saw, this VI gets slow when handling large arrays (I saw about a second for a 2800x1500). Does anyone have any optimizations ideas? I know that when windows creates thumbnails it also takes time, so I'm not too optimistic.

Use the Crop tool.
Thanks Appleman, but the crop tool, cut off parts of the picture.
To illustrate my problem, I have a picture & this picture consist of one face. So, this face covers the whole screen. But what I want to do is still to have the whole face but NOT covering the whole screen as I need some other spaces to put in text (I do not want to overlay the text across the face).
Ay ideas ?
Thanks

DVD studio pro how to resize background picture? I want my photo be a background but cant find how to resize it to fit the screen.

Hi Miron,
You are best off taking the image into Preview or Photoshop and resizing it to match your framesize. You could use a button and resize that but it is not economical or pretty.

How to resize a picture to letterhead sized

How do i resize a picture to letter head size in cs4?

Image>Image size.
Then in the image size dialog box type in the document size.
The quality of the print will be dependant of the original pixel dimentions. The lower the pixel dimentions are the lower the quality will be when resizing. It is prefered to have the original image be larger than the final print size when you first open the image. But upscaling can work and has but only if there is enough detail that will be satisfactory to you after you scale the image.

Perhaps it would be helpful to explain what it is you are trying to accomplish.
Is it that you are trying to save drive space and want to reduce the file size of the photos? Or is it that you need to send the photos somewhere (upload, email, etc.) and again the file size is an issue? Or is it that you want to make a print and need to know how to print it out in the size you want:? Or do they simply look to big on your screen and you want to display them smaller?
Patrick
Thanks Patrick,
My purpose is to edit the picture so that I bring them into iMovie09.
When I placed them into iMovie09, they simply look to big on the screen and I need it to display smaller
Thanks

How to resize a layer or picture

I am brand new to anything PhotoShop. I have created a talk balloon that I plan on putting it on a photo. I have the text on it already. However, the area outside of the balloon must be tranparent. I made it transparent pixel by pixel. There must be an easier way. So my two questions are:
1. How to make an area of a picture or layer transparent?
2. How to resize a layer or .jpg picture or any picture that can be edited by PS Elements 12
Tried to include the talk balloon file but it failed because of the content. What is wrong with " Hmmmmmm"
"I think this one fits". It is a psd file.

1. How to make an area of a picture or layer transparent?
Select the area where you want it to be transparent and use the Eraser of various types from the tool bar. there are essentially three types: Eraser Tool, Magic Eraser and Background Eraser. The selection tool has also many types.
How to resize a layer or .jpg picture or any picture that can be edited by PS Elements 12
To resize any picture you simply go to:
Image >> Resize
Select what ever you want to resize the canvas or the Image. If you are in PSD file then canvas resize might be appropriate but my answer is pretty general to give you the necessary options. there is also the "Scale" of the image so you are spoilt for choices here.
You just need to be careful not to0 degrade the image so much by resizing because pixels per inch changes and lower the amount per inch degrades the image; This is what happens when you increase the size while reverse is the case if you resize it downwards.

How resize a picture?

How can I resize a picture? All my pictures have more than 1.8MB and I want to resize some of them to a smaller size (200KB or less).

Jose Frank:
You can resize the pictures via the Export process. In the File->Export->File Export menu option there is a section to set the pixel dimensions to a given size and quality level (jpeg compression). The exported file will be reduced in size considerably.

TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 08 libraries and Leopard. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

How do I resize a picture on my ipod 4g before emailing it?

The manual says it asks you if you want to resize the picture when you go to email it, but mine's not giving me that option? Help!

I noticed that too. Everyone I've talked to that has the Itouch all say that when they go to email a picture, it asks them if they want to resize it, but mine doesn't. I've looked in all the control settings on mine and can't find anything related to resizing before sending. So I didn't know why mine wasn't working and asking me.

How do I save pictures from iPhoto iPad app in full resolution?

How to resize project without losing the image resolution?

I am trying to resize a project that recorded in 1271 x 768
px to 800 x 483 px. I did it by clicked 'Project' > 'Resize
Project...'. But after resize, the resolution of the movie is not
clear, became blur. How to resize the project so that I'll have
clearer movie? Thanks.

Hi obtis and welcome to our community
Unfortunately, there is little you may do to avoid this. The
best way to avoid it is to simply record initially at the size you
need so you don't have to use the Resize function.
Here's the deal. Captivate stores images in the project as
bitmapped images. Otherwise known as "raster" images. Basically
they are a mosaic that comprises the picture. Initially, all is
well and is crystal clear. But when you scale down a raster or
bitmapped image, you are simply moving all the picture elements
(PixEls) closer together. They overlap and the computer will
calculate new values for what color they should be. Depending on
how much you are resizing, the clarity drop can be acceptable or
horribly bad. The more you resize smaller the worse it gets.
Hopefully this helps... Rick
