Simple automatic cutting graphic black and white

I have a lot of images that vary according to the size. All rooms have a simple black and white chart like the one shown below.

Is there a way I can automatically crop these images as there is no superfluous white borders. Is that the harvest should touch the edges of the black areas. If all images have the same size, it would be easy, but this is not the case.

Thank you.

Try the Image > Trim and see if it works for you.

Note that there are all the foreign black/gray pixels in the white area is cut at this point. If this is the case you can first make an adjustment of threshold set pretty low.

  • I need to change my black and white a PMS color chart

    How can I do this? I made the graphic black and white so that the client could print any PMS color they wanted. The client is now asking me to provide a file that will sample in a few PMS colors and I don't know how to do this b & w print in a specific PMS color. I know of Hue/Saturation, but how do I get it to be exactly like the PMS color? Help!

    You could have white selected as the ink for the two-color, or you might have a defined curve to kill all of the ink. Hold down the ALT key while in the Duotone box dialog and 'Cancel' should become 'reset '. Restore dialogue and set the ink by clicking on the black square.

  • Photoshop CS5 print color in black and white graphics

    I have Photoshop CS5 12.1 x 64 on a MacBook Pro with OS 10.10.5 with a Canon Pixma MP560 printer. Until a few minutes ago, has been printing very good Photoshop, but now it prints all graphics in black and white color. Before posting this request, I tried the printer on several other applications, including Word, Firefox and Adobe Acrobat, and all are printed correctly. Apparently, I clicked inadvertently something in Photoshop which has not extinguished color printing. I've attached a screenshot of a dialog box print in Photoshop with a simple image two-tone. I hope someone here can help you.

    In the first screen, uncheck grayscale printing. It is another name for black & white.

    In my opinion, you need to connect the laptop to the external display just to check if its display problem internal or maybe the graphics card issue. I think its GPU problem, but an external monitor is worth a try.

    However, in both cases the defective part must be replaced. :(

  • Black and white raw Images are automatically colorized - why?

    I use a Lumix GF1 and shooting in black and white and gross.  I have the latest Adobe Camera Raw program (5.6, I think), Photoshop CS4 and bridge.  I have download the images from the camera to my pc using Bridge.  They appear in Brdige one by one in black and white.  After the last image, Bridge Converts the color automatically - and I can't understand how to stop it.  Can someone help me?  This only happens for raw, not JPEGs images.

    There is no such thing as an image "black and white vintage" or an image file.  The B & W is just a label in the metadata that tells the camera software to show you a picture of b & w, but the raw wll file still have the color information.

    Camera Raw by design ignores the tag b & w owner defined by your camera.

    You can always convert to grayscale in Camera Raw.

  • Photosmart 8450 prints only black and white with the new Mac with OS 10.6

    I just bought a new Mac with OS 10.6.  (former was OS 10.5)  Now my Photosmart 8450 will print only in black and white.  I installed the single upgrade on the site of HP, no change.

    Is there an other update I need?

    You want to disable automatic session opening, which may be why it behaves in this way.

    Go to System Preferences

    Go to security

    Under "for all accounts on this computer", place a check mark next to 'turn off automatic connection.

    In addition, I do not know if you set a password for the test account, but put something simple as 123 - just something / anything.

    Once that is done, choose log in the Apple menu, or reboot. This should bring you to the login screen where you can specify the account to enter.

    The system restore solved my problem and after that I had to do it AGAIN today, I went to Windows Update and changed the settings so that the updates would not automatically download and install on my computer.  It is certainly a problem with one of the Microsoft updates.  I just hope that they recognize that one and let us know as soon as POSSIBLE!  I'll be very selective on what updates, I am hosting in the future!

  • Tecra A6-EZ6411 - video photo is shrivelled and black and white

    After a recent update to Windows 7 I have a problem with the display of images in the Windows image viewer and watch netflix videos. I can look and onto my computer without problem. I can also display an image in paint.net or any other picture watching a program. I can watch Hulu or any other site of company of cable without problem. What is happening is that the image is overwritten and made black and white.

    So the first thing I tried was uninstall silverlight and then put it back. The next thing I tried was start in basic mode, uninstall all nvidia drivers, then reinstall the latest driver available. None of those corrected these problems. Strange thing is when I first start in basic mode and the resolution is 640 X 480 photos appeared normal in the Windows image viewer and when I try to watch a video on netflix seems normal. Only when I change the resolution to anything else he revert to the old diplay of a black and white display shrunk.

    Hey,.

    You have the same problem with the version preinstalled Windows from Toshiba or did he only because you have upgraded to Windows 7?

    I mean if it works with the screen resolution of 640 x 480, it could be the graphics card to malfunction but a problem of driver too so much easier is to install original Windows of the Toshiba recovery disc and it tests again.

  • Tecra A3: TV - black and white display

    I have a Tecra A3, which I tried to connect to a TV via the S-video connection. Works, but the TV picture is black and white.

    I tried to change the Graphics Options without result. These are currently on:
    Colors: True color.
    Screen area: 1024 x 768
    Video Standard PAL-B

    Everyone you have any other suggestions?
    Thank you.

    Hello

    This unit has a S-video out. If your TV has only video then you will get only a black and white screen.
    To get a color screen, you have a TV with S-video
    Also, check if the TV works correctly with the standard NTSC video.
