  • problem with image and pdf files to print

    Hello

    When I want to print images and PDF files in windows 7, it takes too much RAM space so small capacity it has (for example, the file has 52 KB capacity, but it takes 21 MB of RAM)

    and I have to wait until this file (image or PDF) completely buffered in RAM, and that is problematic for me.

    Help me please.

    Thank you

    Hello Amirafshari,

    Thanks for posting your query on the Microsoft Community.

    We need to know the following information to isolate the problem:

    1. When you print files no PDF, you have the same problem?
    2. What are the specs of your PC?
    3. Where are the files located? Is this an internal or external storage device?
      • If the file is located in your external storage space, you can transfer into your internal storage space first before printing.
    4. Have you tried the activation and deactivation of your print spooler? If this isn't the case, please follow the steps below:
      • Go to CMD.
      • Type "net stop spooler" and press ENTER to stop the spooler.
      • Type "net start spooler" and press ENTER to re start the spooler.

    Let us know how things are going.

    Kind regards

  • Backup of images to pdf file of Java App

    Hello

    is there a feasibility to save images that have been responsible for res folder on the screen for the file PDF.

    Scenario goes as it will be set to images in the Horizontalmanager and by clicking on the image particular necessary to save it as a PDF file, then on SD card.

    Thanks in advance.

    After my post, I wanted to see if I could create a basic app that does this. It took me a little while, but I finally had the time to work on it.

    Visit the following site (it is one of my libraries):

    http://BBX.codeplex.com/

    Choose "source code", then "Browse".

    There is a directory called BBX_PDF. There is a small library to make PDF files. It's very raw. Both in use and in the code. There is no real speed or memory optimizations. To use it, you would spend in Hashtable, tables and specific objects. Then call the function write and he would write the PDF.

    The specific thing that you wanted, I did a "Builder" class that is available in the folder 'Other' BBX_PDF.

    It binds to one of my other libraries (BBX), but you can simply remove preprocessor components to get the generic version of the code.

    Edit: There is a bug in the Image2PDFBuilder class. When an image is added, it's really small. I always try to understand this, but if you understand it, thanks for posting this you fixed so I can update the code.

    Hope that helps.

  • Question about PDF files with linked images (not embedded) between the player and Illustrator

    What I will meet situations when I get a PDF file to client that must be changed. When they load in Acrobat Reader, it works fine. However if I load in Illustrator it asks me to point to the linked file. The question is how Acrobat Reader to open a PDF file and display a linked file when it is not incorporated? Why Illustrator cannot do the same?

    It is more of a technical issue, but any information would be helpful.  Thank you.

    For the associated images, your PDF file contains a thumbnail image as well as the reference or the address of the actual image. Player will show this vignette. Now, you want to change the PDF in Illustrator, he wants to allow you to work on the actual image. That's why it asks you to point to the linked file.

  • Cannot resize the PDF file

    Hello. I bought a new 6830 yesterday and I have a problem of scaling a PDF file to print. When I got back the PDF file, the image is reduced in the file, but prints in original format. Today, I visited the Adobe site and found a page called Acrobat PDF Help/Basic printing tasks. According to Adobe, when I open the print dialog window, I can change the page to shrink or expand by setting the size I choose in the scale box:

    Custom scale  Resizes the page by the percentage you specify.

    However, my window of dialogue has no custom scale option. I'm starting to wonder if this printer allows resizing. Any suggestions?  Thank you.

    I installed the driver, Officejet Pro 6830 and it allows resizing in Adobe Reader 11.0.10.  I suggest to update to the latest version of Adobe Reader.

  • 'place' blurry images Photoshop Illustrator - at check in .pdf file?

    I edited some images in Photoshop for use in a .pdf file I created in Illustrator.

    In PS, images was beautiful and have been registered with the following parameters: .jpg/CMYK/Image Options: 10/Maximum. I have "placed" in the Illustrator file, everything was always wonderful, but I exported all of the .pdf file, the pictures came out blurry.

    The resolution is 300 dpi for images of three, all pixels of 170 x 100, which is also the size, they are used to in Illustrator.

    I note also that during the "placement" images in Illustrator, regardless of the type of file, the images are invariably much smaller that originally saved as. It's never happened before.

    Any ideas on how to have clean images, in the PDF?

    Things, I tried with no sign of improvement:

    Standard, high quality print and print quality save settings

    Save images as .jpg, .tiff, .psd in Photoshop to place in Illustrator

    'Link' and no 'link' when you place it in Illustrator

    Save images 2 x and 3 x the size in Photoshop to reduce in Illustrator

    And a cap perforated how I'm viewing the PDF with the images at 100% in Acrobat:

    Screen shot 2012-09-29 at 5.17.09 PM.png

    The quality is affected by their scaling upwards - at least if that's what you were doing with the placed files.

    170px wide at 300 dpi works be 0,5667 inches wide. Did you leave them this size or you increase their width/height?

    If you resize them, what size do you want in the publication? Let's say that you want them to be 2 "wide. 2 inches x 300 DPI is 600px wide at 300 dpi.

    Take care, Mike

    Edit to add * using my desired example 2 "width, if we place a 170px 300 dpi image, enlarged width 2", the effective DPI is approximately 83 dpi.
