Automated process to crop away some pixels

How can I automate the process of cropping away some pixels around the edges of a lot of photos of different size?

Example:

Photo 1: 400 x 600px

Photo 2: 360 x 480px

Photo 3: 600 x 800px

I want to crop 5px away from each side of each image which would then eventually be 390x590px, 350x470px and 590x790px respectively.

No action will work if you tick the 'Relative' box and enter the amount you want to change the size of the canvas.  The seal shows an example of the size of the canvas being reduced by 5 pixels.  This works on any image size.  She will be always the image out of the surface of the canvas, but if you are saved as png or jpg, then that will be deleted, so it's like the crop tool.

    How would you like non-destructive change the color of some pixels depends only on their current color?

    Constraints: the goal is to avoid having to select with the lasso tool or any other tool. I'm talking about adjustment layers here, who would not need to select parts of the first image.

    The input image has only a haldful of discrete colors: it is made of, say, about 10 areas with 10 different colors, alias 10 different RGB values.

    The goal is to find a way to organize the adjustment layers and only pixels with given RGB value (for example) blue, while some other pixels with another RGB value data become red, etc. ?

    I will then apply these to each image adjustment layers in an animation, to selectively change the colors.

    If I understand you correctly, "Mix" so should work.

    Here, you can target specific values/ranges in each channel, for the underlying layer and current standards.

  • Crop Photo Alters Pixel color value data - is there a work around?

    Hi all

    So basically, I'm batch cropping of the thousands of images at once. Here are the multispectral images - so that they have 5 channels. I crop in chimneys-5 layers by highlighting the layers and cropping the same dimensions for thousands of these (automated as a batch) multi-layer images.

    The problem I have is that when I crop a picture, it alters the colors very slightly compared to the battery under cover; Each layer in the stack is modified slightly in color. I need to keep the same values of color for pixels after cropping.

    Does anyone know a way I can crop an image while maintaining the same values of color/DN for the pixels, as the original game? I use Photoshop CS6.

    Thank you!

    How are these images saved - file format? PS open them in the same color space as the original files and saving them in the same color space?

  • Processing multiple files makes more pixelated?

    I have pictures for my online store which can be really big zoom without distortion.  So I leave the dpi to 300, and run several tests on my mac all with the exact same start/size of the picture everything.

    1. I'm resizing in PSE 14 without using several files processing.

    2. I'm resizing in PSE 14 using several files processing.

    3. I resize preview and don't use all PSE.

    In these contexts - each time, the size of the file is greater with PSE with preview (547KO vs 114ko) - which is a big problem when I have lots of images per page.  The quality of these tests are all to minimal difference range - it is negligible.  However, the quirks start when I add a watermark to the image by using the function 'treat multiple files' - this is where it goes south on me!  Using the preview resized OR resized ESP - anyone, as soon as they get a watermark (and we are talking about only a line of tiny text at the bottom right), the quality gets worse.

    After tattooing, the size of the file on the PES to PES "multiple files" resize watermark (test 1) version will 547KO to 79 KB - and the photo quality is a noticeable difference as well.  Using the preview resized, then PSE "multiple files" (test 2) for watermark, it passes from 114 kb to 83 KB.  Not much difference in size - but I would not have expected a big difference in both cases honestly since I'm not actually resizing - but only watermarking.  But the quality of 'Trial 2' is still significantly different from the version "nothing other than the Preview" without watermark (hands down better on the version without watermark).

    I'm completely stumped on how to make good quality, very "zoomable", a watermark images that remain small in size, while maintaining quality.  Any help is greatly appreciated!

    Thank you

  • Value of the element after replacing the automated process of line does not?

    Greetings!

    I have a standard process of line automated filling in the fields on my current form after the header. Certain values that I need to replace by calculations from the data in other tables. If right after the line, I inserted another process for this. The results are actually stored in the database, but does not reach the customer. Why? Somehow it seems, once the line is completed, the html elements are not affected more during the processing of the page.

    So I resolved to set certain values with a call ajax after the page is loaded, but which actually is not the best way to do this.

    In coordination with the question: what is the difference between the headings of before and after? I looked in the documentation, but wrong in details. Myself I havn't found no difference between the two.

    I hope you can help me get clarity on who and how to implement the calculation as well as the shape of line.

    Thanks a lot and best regards,

    Tobi

    Hi TobiP,

    If your item has as the Type of Source database column, and I think you do since your using an automatic process of line Fetch, in the properties of the element, you'll find a region called 'Source '. If the Source value or expression is not null and the Source is set to "Always replace the value that exists in the session state", then the value of the source will be taken from what you put as the source and ignore session state values defined by other processes. Assign to this "only when there is zero current value in session state" to use the session as a source value.

    Kind regards

  • I see some pixelation when zooming

    In animate CC, I used vector graphics, but when I published HTML5, I see no pixelation. How can I reduce pixelation while zooming in HTML5 published.

    Yes, they look blurry when zoomed because canvas mode uses a target fixed-resolution. If your course is, say, 300 x 200, you get 300 x 200 pixels, regardless of how much you're zoomed in or out. This may be attenuated (but not completely resolved) in creative at 2 X or more than the resolution of your screen, then reducing the canvas in the browser.

    If you do a keyword search on these forums for "blurry" or "pixelated" you will find several discussions discuss.

  • Schedule an automated process to reduce the size of PDF files

    I am trying to find a way to automate a process which would take place every night at a certain time. PDF files is saved by my colleagues in a certain folder for printing purposes. My job is to take these files and reduce their consumption of the web size. Currently, I have to do it manually, which is a bit of a problem because these files come very late in the night.

    The optimal goal would put in place a process that allow to monitor a folder and automatically save any PDF placed in said file in a file size reduced. Using the Action Wizard in Acrobat XI, I can't find a way to set up to run automatically.

  • Pixel & crop tool

    I was using the tool of cropping for some time now. I had no problem and she did my job.

    Now, I'm trying to configure a report for the crop tool. It confuses the hack out of me... Someone help me out please (I don't know if it's really considered a question of photoshop...).

    Let's say that I started with a photo of 300 px * 300 px resolution 300 dpi (or 1 in by in 1). Then I use the crop tool (w / setting width 300 px, height 300 px and the resolution of 300 dpi) to crop a little piece. How is that possible? Expanding pixel? I thought that the initial 300 * 300 would have 90000 px. By cropping, I would cut some to. How can I still end up with the same pixel size? Of course, it works; But why?

    In addition, there is a better way to deal with fix ratio cropping, but not size-wise (pixel or physical)?

    Thank you.

    Howdy.

    For the benefit of the walkers and others confused by all this, I thought I could elaborate just a little bit on the concise answers to Christmas.

    If you enter a dimensionless number in the width and height of the options bar boxes, Ps automatically apply pixel dimension. To avoid this, you must type in one dimension other than pixels, i.e. inches. Otherwise, Ps will be re - sample.

    You can also configure presets for various reports aspect as below and do with it.

  • Satellite Pro M30 - some mistakes of color and pixel

    The last days I had some problems with the display screen. I had a few mistakes of color-mistakes and pixels. Colors erupt anywhere on the screen, icons disappear and if I move quickly around the screen (with her pinter) ex a document in Word (Office), I have interference with some pixels/points in the text and also a strange thing as some want to erase the text with an eraser.

    But if I have to "Refresh" the sides where it happened that it is ok again, until I repeat once again. I try a few other HD is the same and I also format the HD, but it is still there (I think it might be a virus).

    Also, sometimes the display flashes until it is regular again. Sometimes, it's better or wrong.
    I guess it may be a failure of the map screen. I also get some stick photo (and rehearsals) when I use the cam on Skype & MSN.

    some hint/tip?

    Hello

    May I ask if you have installed another display driver for your laptop? You should only use the display directly from Toshiba drivers because they are pre-tested on the laptop.

    In addition, it would be interesting to know what happens if you connect an external monitor. You may notice the same problem there?
    Maybe reinstalling Windows can also solve this problem

    Anyway, if you need professional assistance, you must contact the service provider authorized in your country. Technicians can check your laptop. :)

  • crop to selection in action while maintaining the cropped pixels

    Hello

    Is it possible to use the image > crop without deleting pixels outside that culture?

    I have a lot of images with a shadow I want to crop by using their path (selection)

    I do a deed which

    -selects the path (all named ' 1') of an image

    -image > crop the image to this selection

    In this way, the ratio is not contained in the action, BUT the pixels outside of the selection are removed. How do you define culture pixels cropped remember?

    Note: double click on the crop tool will give me the opportunity to uncheck 'delete pixels' but will contain the report of the harvest, making my action null.

    Thanks for your help

    Vanessa

    Ideally, I guess we should create a Script (in JavaScript).

    What structure in a layer?

    If there is only one layer to change it to a smart object, then using Image > Crop (with selection) might be an alternative.
