• EMF Tiff image conversion does not properly on Windows 7 PC

  I have a c# application that monitors the Clipboard.  When an EMF
  comes, I extract the EMF of the Clipboard data and try to
  Save offshore in a TIFF image. Everything works fine on a windows XP PC. However, when you do the conversion to grayscale, the converted image is not readable (blurry) on Window 7 PC (32-bit / 64-bit).

  I have using the standard GDI + for the conversion needs. What could be changed as the origin of the problem? Any help appreciated.

  Hello
   
  Your question of Windows 7 is more complex than what is generally answered in the Microsoft Answers forums. It is better suited for Visual c# in the MSDN forums. Please post your question in the Visual c# MSDN forum.

• Polygon color with RGB U64 images / Image conversion of RGB U64 in RGB U32

  Hi guys,.

  I want to use the color polygon feature, but I have an input RGB U64 image. The only supported is image RGB U32 type. Is it possible to convert the image to U64 U32 and use the color polygon feature?  I know I'll lose accuracy, but what for the moment.

  Otherwise, you know the functions of polygon that supports RGB U64 images as input?

  Please let me know.

  Thank you

  IMAQ Cast Image VI Converts the current image type for the image type specified by Type of Image.

  How Casting works: The VI shifts the value from the source to the range of 8-bit using the depth of specific bit of the source image. Then the VI defines each color component in the destination value for the corresponding component in the value of the source.

• IMAQ JPEG image conversion problem string

  Hi, I'm using the format JPEG decode VI to decode an image string I get a camera at Black fins. It works fine when I run VI himself, but when I use it as a subvi the program crashes. Anyone have advice?

  This is a picture of my program

  

  It's the way the file is returned to the camera

  'I '.

  «#IMJxs0s1s2s3...» »

  Enter the JPEG compressed video image x = size of the frame in pixels: 1 = 80 x 64, 3 = 160 x 120, 5 = 320 x 240, 7 = 640 x 480, 9 = 1280 x 1024 s0s1s2s3 = size of the image in bytes (s0 * 256 ^ 0 + s1 * 256 ^ 1 + s2 * 256 ^ 2 + s3 * 256 ^ 3). ... = full frame JPEG Note that sometimes the 'I' command returns nothing if the robot camera is busy, then the 'I' command should be called as many times as necessary until a framework is returned

  I changed the format JPEG decode VI by changing the plans of red and blue color. I don't know if this caused the problem though.

• A texture image conversion complex in a simplified vector graphic

  Hello

  I have a complex of water chart, I'm trying to simplify and vectorize. I manipulated the image in Photoshop to bring out the contrast and tried pathing image then export paths to illustrator, but the size of the file was obviously great same situation bringing the TIFF in Illustrator and use the vectorization. Is there anyway between programs or both, I can simply and smooth the vector illustration to shall declare the size of the file and make it easier to manipulate, size, color, ect. ? I use the image as texture and it doesn't have to be complex, I would just flow and structure lines.

  I've attached a screenshot of the TIFF Photoshop file I created off the coast of the original photo of the water and the vectorized version, that I have done, by using vectorization, in Illustrator. The vectorized version is a bit unstable and complex. I don't know you have a thing or the best way to do it.

  Thank you very much.

  Color will be easier to handle after vectorization.

  And if you do not want to lose details will not get fewer anchor points.

• Clearscan indexable image conversion

  Is there a relatively simple way to convert a PDF file saved as searchable image format Clearscan? I know that I can open pages in Photoschop, save them under objectives and then convert them to PDF using ClearScan but I'd like to find a less laborious way.

  Barry Cooper

  Yes, there is a direct way. You can run OCR on the file with the PDF output Style defined as Clear Scan. Follow the steps below:

  1: Open the file in Acrobat.

  2: call OCR on the file opened.

  3: you will see a dialog box to specify the settings of the OCR.

  4: change the settings to specify the output PDF as ClearScan Style.

  5: run OCR on the file.

  Your file will now be a ClearScan file.

  Please note that although you can convert a searchable Image file to ClearScan file directly, but the reverse is not possible. So, if you want to convert file Clear Scan to searchable Image, you will need to go through the steps you mentioned.

• Unique spot color grayscale image conversion

  Hello.
  
  I'm trying to convert a grayscale image in a single spot color image. The spot color is PMS425C, color gray, but as I'm only printing 2 colours I need to convert these images in one spot color.
  
  Can someone please help?
  
  Thank you

  Have you seen the monotonous separated to CMYK?  If so, you can not make the PDF correctly and the place is being converted. It can still have CMYK channels, but they are empty and will not end plates.  Check your output to PDF settings and check the ink Manager that the tasks are retained.  In addition, there are more than one way to display preview of the output that can be confusing at first.

  You export as PDF X / 1a and if your settings are correct, when you view in output preview (separations) in Acrobat, you should see the spot as a task.

  Try to save your monotonous as .psd too many other formats will support the monotonous.  If you view separations in ID, you will be able to see if your file supported by spot color.

  Thanks in advance.

  Kind regards

  Jawahar

  Your file PS does not contain the parameters of size or page orientation, so the PostScript interpreter you use

  simply defines the configured default page size.

  As the file defines something as a page covering (the name pagebbox is used), take the fiven values it

  to build a State of page size. For example insert

  < agesize="" [792="" 612]="">> setpagedevice

  right after the comment lines (lines starting with two percent signs). Forcing your PS interpreter

  (condition he speaks at least the language level 2, that I take in silence) to make the formula for a

  Letter size page orientation is landscape.

  If you really want a portrait orientyation, you need to swap two numbers in the

  Statement above and enter the code to scale down the formula.

• Problem making a 1-bit image

  I'm trying to make a 1-bit image and I tried several ways to do but got nowhere with it. I hope someone will see the mistakes I make and show me how to solve this problem, I joined the program I was working, the image I used is also attached it may be I don't know.

  Hey alang.

  by converting into PNG I don't mean not simply to rename the file...

  Your BMP is a 24-bit image, so you should check the output 24-bit image conversion routine. Then you simply check a single color component (as it is a grayscale image) for your level of comparison:

  

• Convert QByteArray QImage

  Hi all

  Is it possible to convert QByteArray QImage?

  Answer please!

  See you soon!

  use the registration method.

  example of http://qt-project.org/doc/qt-4.8/qimage.html#save-2

  QImage image;
  QByteArray ba;
  QBuffer buffer(&ba);
  buffer.open(QIODevice::WriteOnly);
  image.save(&buffer, "PNG"); // writes image into ba in PNG format
  

• Saving image with data in QVariant

  JPEG image is converted to QVariant (with bb::cascades:Image) by using the following code

  m_image is bb::cascades:Image

  m_image = bb::cascades:Image (imageData);

  Converted to QVariant using QVariant::fromValue (m_image)

  The image is displayed in qml. (I can't save the file immediately after uploading there will be a lot of pictures and I have to select and save.) When the image is displayed his QVariant...

  I would like to save this image, who subsequently to use as Photo of Contact...

  I saw the code example

  imageData1 is QByteArray

  Image image = QImage::fromData (imageData1, "BMP");
  QFile outFile("shared/photos/temp1.bmp"); change the path to your file
  outFile.open (QIODevice::WriteOnly);
  image. Save (& outFile, "JPEG");

  I tried to convert the QVariant to QByteArray using QVariant.toByteArray (). but it did not work.

  Any help will be really appreciated...

  The problem is solved by standing around ImageData object of data instead of the Image object. By using the following code...

  Demonstration of QByteArray = ImageConverter::encode ("image/jpeg", myImageData);
  QImage image = QImage::fromData (demonstration, "JPEG");
  QString imgPath = "shared/photos/"+myImageName+".jpg";

  If (!) QFile::exists(imgPath))))
  {
  QFile outFile (imgPath);

  outFile.open (QIODevice::WriteOnly);
  image. Save (& outFile, "JPEG");

  Copy the following code to display the image correctly on Z10, but not on Q5 however both running the same version.

  No idea what could be the problem?

  It turns out that the problem is exactly as described by dbigham, ImageView can handle images up to a certain size depedning on the device.

  I added a C++ code to resize the image before feeding it to QML

  QML code:

  ImageView {
              id: imgView
              attachedObjects: [
