Reduce the size of the image

A relatively simple matter. Using of 1456 CVS and a Basler VBAI camera A622F 3.0, how to reduce the size of the full image while grabbing a picture from the camera via an external trigger? For example, if the size of the real matrix of the camera is 1280 x 960 pixels, how can I reduce it up to 640 x 480 pixels when the acquisition of image while still watching the same area/image, but of course with a smaller image size (or less pixels per square mm)?

I ask this question because while applying the script in VBAI, the time of the loop does not my request to go beyond 20 parts per minute. I need the same script applied on a small image so that it takes less time to run, which increases the throughput of the part. I'm sure I'll lose a few details while doing so, but I think it will be an acceptable compromise for my application. I tested (using benchmarking) between large sample images and 40% reduced the size of the same images. It takes a lot more time using the same script on the big pictures against children.

The camera tool (Format 1 Mode 2 etc) help in this case? I would also appreciate if you have any other ideas / comments on this problem.

Thanks for your reply bruce. But my version of the 3.0 VBAI watch tool geometry which has an option "resampling". The problem has been resolved by choosing a lower resolution on it.

Have a great day.

  • Reduce the image size after scanning

    I have a problem, identify ways to reduce an image in size so it's pretty small to put in my remote (it's the words that I am allergic to penicillin in many different languages, preceded by the corresponding indicator).  I can crop the image so it shows just the words and the flag, but then I want to re-size (but this is grayed out in the list). I am at a loss. I've never had an all-in-one before so am probably being a bit thick I know, but you would appreciate the help.

  • Why print multiple pages per sheet reduce the image?

    Two pages of 5.5x8.5 must print 2-up on 8.5 x 11 WITHOUT reducing the size of the image. Taxation of basic page! (I'm talking about Acrobat DC, specifically.)

    The answer is very simple.

    Acrobat does not currently a tool of imposition of real page. How Acrobat reduced the size of the pages has to do with areas conscious as defined by the printer driver and therefore, even if you try to make a booklet of 5.5x8 pages on paper 8.5 x 11, Acrobat reduced the size of the pages to accommodate the unprintable margins.

    There are third party for Acrobat plugins that perform this and much more sophisticated tax functions.

  • Can there be a script to reduce the images by a percentage?

    Hello

    I'm trying to decrease the file size of a .swf file.  To do this, I'll have to export all images in flash in photoshop, then reduce the size to a certain % to maintain the proportions of the origianl images in the. Fla.  After they have been downsized, I have to then reinsert them into flash and then place them were they should be to ensure that everything is in place correctly.  yeesh.

    So to make my life a little easier, is there a way to set photoshop so that these images (all in a certain folder) can be treated so that they are say, 60% of the original size for each of them?

    Any help would be greatly appreciated.

    If you can create folders on each image that Photoshop should be able to do for you that action of one simple step should you need not a script. Use file menu > Automate > batch Point dialog box to your files and your little batch resize action.  Checking size of Resample image and constrain select the interpolation like Bicubic Sharper method and set the width on the pecent of the initial width like 90%

    Hi all

    I have a document with a ton of images, all of high resolution press ready. I need now this doc to the web, even at low resolution, the pdf file is still 6 MB.

    Is there a way to reduce the images in the file for the web without batch processing in photoshop? Just curious.

    You should be able to reduce the size of the PDF file by changing export settings. In the export settings you can flatten transparency (PDF 1.3 can produce a smaller file), convert CMYK to RGB (output > color Conversion), lower quality of resolution and compression (Compression tab).

  • size of the image file

    Hi all

    I have an application that includes the photo module. I use under encoding settings:

    String encoding = "encoding = jpeg & width = 1024 & height = 768 & quality = normal;

    The problem is the image size. For the same scene when I use 9780 it is approximately 350KB for 9800, it is only 80KB. Can someone please explain the reason for this difference?

    Y at - it no additional or other adjustment means that I can use to reduce the size of the file for 9780? (physical size 1024 * 768 should not be changed).

    Thank you.

    Could not find any additional setting. I used the method to reduce the image quality and therefore the size of the image file without changing the resolution of the image below.

  • How do I keep the size of an Image when it is placed on a new canvas?

    I've worked with a lot of different Photoshops, but recently, I was in another computer so I just Photoshop Elements. I was excited about its use and opens a blank canvas to start working with. When I pasted into another image, he immediately reduced the image to fit at the height of the canvas, which is not what I wanted. I want the image to maintain full-size when pasted in the new canvas.

    I've scoured Google for an answer to this, but the answers do not work, I can not find them or my mind is not enough common sense to understand what they are saying about tech.

    Any help would be greatly appreciated. Thank you!

  • How to reduce the size of the jpg file, not the size of pixel?

    I prepare images for the web and I really have 2 questions: one on gifs and the other on the jpg files.
    My standard procedure is to reduce the image to the desired at 600 dpi pixel dimensions
    It gives me a little crisp image. can I use this what if the file size is quite low (I try for less than 600 KB) or convert to gif with the save for Web and devices.

    Here are my 2 questions (I'll count this solved with each answer)

    (1) when I convert a gif that I have 4 boxes: one with the original size, the other 3 with options but, often, the options are too low resolution for me how can I change my 3 options starting with a higher res gif?

    (2) if I try to reduce the size of the jpg in the image size box I put the lower resolution (400, 300), which reduces the pixel dimensions and the size of the file, but I don't want to change the pixel dimensions. If I reset the dimensions in pixels to the size I want, even if it is a lower resolution that the file size does not change. How to reduce the size of the jpg file using only the resolution, the pixel dimensions not?  PS I tried to play with the checking and unchecking the 3 small boxes (scale of styles, constrain the proportions and re - sample) but nothing has worked.

    GIF is not a type of large file, especially if you want a sharp image. What are the dimensions of the pixel?

    For the web, it is immaterial that the dpi is, only the last pixel dimensions, so once you have that you want to use 'save for Web and devices' and you can reduce quality - 100% being the maximum and 0% being the lowest. I wouldn't save anything less than 55%. For an image of 600 KB, the size must be large enough.

  • Try to reduce the size of the file of my opening a flash site page

    I use the Flash CS4 IDE, and the first page of my site takes more time to load I want that there.  So I tried to go through the various images / symbols / movie clips / sounds and so on to see where all the memory is be chewed.

    When I go into my library, however, I can see the name, the binding, the usecound and the Type of my items, but no mention of the size of the file and I can't seem to find that a right-click menu that allows me to add the size of the file to the list of the details shown.

    Is there a way to see the size of the file?  Or a workaround?

    And are there best practices to reduce the size of the file except using symbols for everything that is used more than once and reduce the image and sound quality?

    Thank you

  • Lightroom 2.5 size of the Image when printing

    I have searched and tried several approaches but can't LR to adjust the size of the image when printing.

    For example, I have a Page of Laboratory Test tif image that has a size of 23 "wide x 29" H paper and resolution 180 dpi.

    I can use CSR 4 Image/Image size to change this in a 8 "W x 10.5" H and a resolution of 320 DPI using resampling. The reduced image prints correctly in CSR 4 on paper 8.5 "x 11" and translates. 25 "top and bottom margins. The same thing happens in LR 2.5 with the reduced size image.

    However, if I try to print the original image using LR 2.5 to automatically resize the image it is malfunctioning. I tried all kinds of combinations of settings so that it can reduce the image (as is done in 4 CSR) and print with. 25 "down the margins without success. The image can not resize correctly.

    Is it a bug, a feature?, or operator error? Can anyone tell how LR 2.5 will resize automatically so it prints correctly? I tested on other computers with the same results.

    Thank you

    Go to the print module.

    Select print to jpg.

    Set the resolution at 180 dpi.

    Other output parameters, sharpening, profile of such paper as required.

    Determine the size of margin according to the needs.

    Set the size of the cell to the size of the image

    Set the Dimensions of the custom paper size... 29 "x 23" in this case.

    You can drag the size of the cells and the edges around until get you exactly the layout on paper, you need. So how successful final print to the file, name the file, and the work is done.

    If you want to print a different size, with different resolution, on paper of different size, with different borders all this can be done in the print module and it is WYSIWYG if no guess work (or calculations) involved. LR rather PS this also has the advantage of use much better algorithms for images of migration than PS and application output sharpening for the specific media type, to which you intend to print, using the RAW data

  • How to create a rectangle of fixed ratio and move without cutting the image?

    I know it's a simple question with a simple answer, but I did not yet find that answer. Usually, I crop my photos in a size 2 to 1 fixed ratio for Twitter. I used to extend the fixed ratio to the size I wanted and then move the tool of selection of ants marching to the area I wanted to reframe. However, in the last few months I'm not able to move the selection without cutting the photo. I used to create my selection and move the cursor over the moving dotted line and then move the selection. This is never a problem. All the answers as to what I might hurt?

    Thanks in advance.

    Sandra

    If there is no selection and you move the selection with the "MOVE TOOL" it will reduce the image

    To move the selection without cutting image, use any 'Sélection' tool instead of the move tool.
