• Convert an image to grayscale 10-bit color

  Hi all

  I am a programmer of experience of labview 8 years, but new to the procession of the image or NOR-Vision. And now, I came to a problem with the conversion of the image.

  I have an image acquisition card that acquires 1 k * 1 k 10-bit grayscale image, I saved the image acquired in *.raw (binary) format, and now I have to convert these images to bmp (jpeg, png, or diff) format. When I try to use the VI "Imaq save 2", I got an error saying something like "unsupported image type. After searching this forum, it seems that if I have to use an image of color type save as bmp format, but to receive my 10-bit RAW files, I first need to create an image in grayscale U16. So, how can I solve this problem?

  Thanks for your suggestions!

  My guess: you're referring to the 'writing IMAQ 2.VI of the file' as I do not know everything "IMAQ save...". Screw.

  The 'writing IMAQ 2.VI of the file' does not support writing 16-bit BMP.  You can take this information among image types supported this VI, see here.  Look at the pictures above, the designation of VI: 'IMAQ writing file BMP 2' says that he accepts "U8" and "RGB32 image types.

  Proposal: Write a PNG image.

• Convert images to grayscale

  Hi guys, I have a problem for you, experts...
  I inserted a few RGB images in my reports (MS Word, PDF output template); in some cases, I need to convert the image to grayscale.
  Y at - it an option of the BI Publisher that helps me to achieve this goal? Maybe in the same time, or in the model (where I address these images with url syntax: {concat('${OA_MEDIA}','/',//LOGO_AZIENDA)})...?
  Thanks for the help

  The only way I can see this working is now convert 'before' files as Tim States above and then wrap them in a conditional statement that determines which should be displayed.

• How to convert images to Grayscale black and white

  I don't have a scanner.  When I need to analyze something, I place under a piece of glass and shoot with my digital camera, then transfer the file jpg on my PC.  My "scans" interpreted that way many pages of text n & B, so the jpg that results is enough grayscle; because I do not use an official copystand there are a good amount of shadow in the image.  It is quite easy to desaturate these images so there is no color in them, but there are still a lot of tweaking if I want to remove the shadows and the end upward with an image strictly B & W.  It seems to me that there should be a filter that allows me to set a threshold such that everything above the level is rendered in form of black (or white), and everything else is rendered as white (or black).  If so, what is it?  Thank you.

  Image > adjust > threshold for this. But I am pretty sure that is not what you want, the result will be crap.

  I would use levels to set the white and black points and then curves to increase the contrast. You can do both with curves, but endpoints are not as easy to spot there.

• Convert image to grayscale in alpha?

  I would like to convert a bitmap to an alpha image grayscale, where a white pixel is a pixel with 100% alpha, a black pixel becomes 0%, gray is 50%, etc.. I tried to do this several ways in Photoshop, but nothing seems to work. Any suggestions?

  Thank you very much.

  By clicking on the thumbnail of the mask works for paint, filters, etc.. But for the collage, the mask must be both the target and visible or Photoshop creates a new layer.

  Using your plan screen example, if you decide to click on the thumbnail of the mask the screen will change in white with a black border. It is the view of the current mask. Now when you paste the mask (and view) will change the image. Choose click on the thumbnail of the mask to return to the normal display that will be the image being masked by luminosity.

  Does not include the LabVIEW code you posted anything to send the image to a file.  I'm curious to know if we run out of questions at this point.  If we comment out code to convert grayscale, writing original image to the file properly or you didn't post in events where you say it works?

  I guess that LabVIEW code, you have published work to complete the task.  It's a little different from what I posted.  But I am not too concerned about that as long as things are working.

  The code works now. The problem is there:

  If (Log_Imaqdx_Error(imaqExtractColorPlanes (captureImage, 1, NULL, NULL, processedImage)))
  
  

  Instead of Log_Imaqdx_Error, it must be Log_Vision_Error.

  Try to update your video card driver to exclude

  Then reset your preferences - with Photoshop CC you can do it in the preferences. Earlier versions require that you press the modifier keys that you launch Photoshop. Ctrl alt shift on Windows or cmd opt shift on Mac.

• image to grayscale to color

  I have an image in grayscale I placed in Illustrator CS6. I would change the black to a Pantone color - turning it into a kind of Duotone.

  Is this possible or do I do in Photoshop first?

  I found a way "descendant" to do so using the change > > change the colors. But I must first choose to invert the colors, then adjust the balance of color..., then set the color opposite mode CMYK, then invert the colors even once. It is a major concern and will not work with a Pantone color.

  Thanks for your help, everyone.

  -Scott

  If a raster image, simply apply the Pantone color as a fill color.

• Print images in grayscale with color covers

  I have an Illustrator CS5 document that uses placed images in grayscale on a white background. Everything seems on screen, but when I print the file a warm gray selection border appears around each image. I tried to use a Photoshop native files transparent, the EPS and TIFF files, but the problem persists. I am Mac OS 10.6.6. Everyone knows a similar problem and, if so, how do solve you?

  Thank you.

  Bob,

  If you save as PDF, buttons appear when you open the document in Acrobat/Reader to screen)? If this isn't the case, I think the question is outside of Illy and with the printer (pilot).

  Y at - he interpreted by the printer color management (pilot; you should be able to see under the ownership of the printer or something)? If so, try disabling it.

• Convert "I16 in grayscale" to "RGB U64.

  Hello

  I need to convert an image to Grayscale I16 U64 RGB, but it does not work (I joined a zip file).

  I think that there is a bug in the Vision of OR, or it is not implemented, because I have no problem to do Grayscale U8 to RBG32.

  Can you help me find a solution for this?

  I need to use the function ReplaceColorPlane or equivalent because I have to perform various treatments on each channel (RGB).

  Thank you

  Hi Badgones73,

  U64 image consists of four U16 values (R, G, B and alpha). LabVIEW represents 16-bit images as an I16. When the plans of color extract IMAQ is called, U16 value must be converted to values in I16. This is done by converting all values with the most significant byte of the 1 to 0. This means that all values of 32 768 to 65 535 are now 0. To avoid using the loss of these values, you must read the image in LabVIEW without using the functions of the vision.

  Once you have extracted the U16 values, they can be converted from U16 images images I16. Once this is done, you will be able to use all functions of the Vision.

  Also, I invite you to read the information on our site:

• Change of brightness of the image in grayscale once introduced in Muse

  Why my image in grayscale loses brightness after I place it in a slideshow widget in Muse? Help, please!

  If you mean a grayscale JPEG, then you will need to convert it to RGB in Photoshop. Working with modes of alternative color if not always requires the color management, which most of the time is not recognized on the web.

• Mode > convert > levels of grayscale, RGB %s

  I understand that the Mode > convert > grayscale uses the channel mixer, anyone know what percentages of red, green and blue channels are used to create the image to grayscale?

  Yes I see. It is the default value for the conversion to grayscale in Photoshop.

• convert images

  Hello

  I want to convert image format jpeg bmp .is there a way to convert jpeg to bmp.

  Unfortunately no, the BMP format should be relatively simple, so make a writer shouldn't be hard. Just know that an EncodedImage returns an encoded image. a Bitmap returns the color of raw RGB/A information.

  A good explanation of the BMP format is actually on Wikipedia: http://en.wikipedia.org/wiki/BMP_file_format

• Converting Images to CMYK for Print Publication

  When in my workflow should I be converting images to CMYK for print publication?

  Currently, I shoot FIRST pictures with my SLR in Adobe RGB, import images into Photoshop for manipulating and then convert the final image, the size to CMYK before placing it in my Indesign document. Before you go to print, I convert my PDF files using the [PDF / X - 1a: 2001] preset. I use a system that is balanced with a profile for my monitor.

  As many of my photos have shades of green, I am often disappointed by the conversion to CMYK because lose I the saturation and brightness. I'm doing something wrong? Is there a better way to preserve the quality of the color in my images when you go to a printer?

  Never. Leave it as RGB.

  All modern printers should happily accept RGB images. PDF/X-4 is the modern

  standard. X-1a can be described as archaic.
