Trouble matching the color of the background of my displays the color of the background of a chart saved in the PDF format

Hello!

I have produced a graph in matlab with a background color of R = 20 G = 33, B = 43. I saved then this background to PDF using export_fig (for some reason that this process has changed a bit the background color). Now I'm trying to match the background color of my poster of the graph, but given that the color has changed in the export process, I don't remember the RGB values. I tried to use the eyedropper on the PDF image, but the software said that it based the color measurement on a low-resolution RGB version since it's a PDF file, which ends up making the color applied to the background of the different poster than the chart.

So, I essentially need to precisely define the RGB values of the bottom of my chart.

Thanks for any help! If there is no confusion, I could send you my chart.

I don't remember the RGB values.

You can check values chromatic AcrobatPro matlab via print > overview of output > object Inspector. Here I chose the object Inspector of the popup preview and clicked on the object I want to taste.

I can see that the profile is sRGB and values of color in the form of percentages. To convert the percentages in ID RGB values multiplied by 256 (for example the channel red est.07800 x 256 = 20). Make sure the RGB profile assigned in your InDesign document is the same profile and plugin your background color of RGB RGB numbers.

    5. Choose install AMYUNI Technologies - Amyuni Document Converter 300 (click the button update windows if it is not on your list).

    6. If windows detects you already have a driver and then choose to replace the current driver. The printer name Quickbooks PDF Converter - do not share the printer - NOT set as the default printer. Finishing

  • 100 HP LaserJet color MFP M175: scan to the PDF Format

    Hello

    While using the scanner of HP LaserJet 100 color MFP M175a I don't get an option to save the file in PDF format. I use a scanner through Windows Fax and Scan. Kindly help

    Hey @HBootwala,

    Welcome to the Forums of HP Support!

    I see you are trying to scan PDF documents of your 100 Laserjet color MFP M175a printer to your computer for Windows 8.1. I can help you with that.

    To start, make sure that the printer is plugged directly into a wall outlet, not a surge protector. Once that is done, scan, you want to scan using HP Scan, rather than Windows Fax and Scan. You can download the latest version of HP Scan by clicking this link. Once installed when you need to scan, you can open the program and select this option to save your document in PDF format.

    Please let me know if this solves your problem by clicking on accept solution. If you still have questions, please let know what happened during the installation of your software and I'll be better able to help you. If not, have a great day!

  • underlined text retains do not fill color to the PDF format saved in 6 IND.

    After typing a Word, create outlines, then add a dash of contour (say 1 pt), the original color barrier does not appear in the PDF that I previsualisez in Acrobat Pro. The word appears as outline only.

    I have to go back and put the same word (before describing) on the version described it "appears so" as filled in the following PDF.

    I have attached a screenshot. This image shows the word red, KINGDOM, has been exposed, but I put the (unexposed) red text above (InD) to make it appear as being filled in the PDF file. Words in blue, ETERNAL and POWER, are also described and briefed on InD, but I do not you cover them (as KINGDOM), to show the appearance in the PDF file.

    I've also attached a screenshot of the original with the same text as InD doc indicated (accident 1pt stroke) which seems OK here before registration in PDF format.

    The word MINISTRIES is not described. It is the original text.

    It does not appear in 5.5, I recall. Any ideas? What is a parameter InD I missed or pref in Acrob Pro?  Thank you

    no fills InDes.pngfills InDes.png

    Now that I see this particular problem with the text of Bauer, I know how to deal with them in the future. I just wanted to be clear that this was no InD or PDF. Trajan is a close substitute. As Bauer is already established in the context of this logo, it must stay.

    Perhaps in the future the leaflets (with logo), I could save in jpg format only, which eliminates the problem of contour.

  • Question of feasibility: extract information from the fields to the PDF format

    I explore options to collect answers to a PDF form.  Fields of entries by the user are created, the user saves the form in PDF format and sends the return form.  The data entered by the user entered in the fields can be retrieved electronically?  I hate the very idea of renewing the data entered by the user to get it in electronic format.  For now, the question is ' is it possible - extract the entries by the user of the data in an electronic format?  If possible, then I can begin to explore the format, etc.

    It is worth noting since you stevat from the outset that it may be problematic to rely on email. Much better to send the form just like an HTML form. This needs a professional web programmer to provide web scripts, however. Also PDF forms do not work on some browsers and phones.

    It is easy to assume that the big trick is to design the form. But it's just the 10% above the water. Personally I wouldn't consider PDF forms more due to browser issues. Same Adobe move to a dynamic conversion to HTML forms then why don't no start with a? There is full form service providers that provide tools to collect and analyze. For example forms of Google - create and analyze surveys, free.

  • Captivate 9 saved in the pdf format does not not in web browsers

    Hello

    I tried to download PDF files e-Learning interactive on my site to use as a portfolio. The e-Learning programs have been created in Powerpoint, and then loaded into Captivate 9 to add interactivity and saved as a PDF for the web. However, these PDF files opens in a web browser. The only problem I can find is when I open "Inspect" in each pdf, a warning indicates "/deep/ based communicator". Unfortunately, I do not know what it means or where to go from here. Any ideas gratefully received.

    I don't know exactly, but it means that you have both Adobe Reader and Flash player (working together) were installed. What happens with this collaboration when the pdf file is displayed in (that) web browser, have no idea. It may also be due to something totally different, but I suspect it might be linked to this change for Adobe Reader (since XI (I think).

  • images of overtaking when you add to the pdf format.

    Hello

    I create an image to use as a stamp in adobe.

    Because I didn't know the size that the user needed, I decided to make several different size copy and then import them into a pdf file I will send to him.

    size are 407x193px, 252x214px, 500x237px, 525x245px, 591x282px, 736x352px ' all the jpeg.

    Something strange happens when I import them. the size of the pdf page becomes gigantic from 525x245px.

    Does anyone know why it would do that, I had checked that the size of the images with paint "it shows at the bottom."

    Is it possible for me to resize the image.

    "As a result"? According to what? Actually, Yes, in accordance with the resolution (DPI/dpi). What IS the size of your image in mm/inch? Or resolution?  Without this information cannot guess what is going to make Acrobat.

    Hi Doug,.

    You can use reports and Jasper. Jasper is a library, so you can add it directly to JDeveloper.

    To include the library in JDeveloper:
    1. right click on your project and go to the project properties.
    2. go in libraries
    3. Select create new library and include the path to the jar of Jasper.

    After that, you must follow the instructions on the site of Jasper reports (it's an Open Source project) to see how it works.

    For more information about the reports of Jasper, please take a look at http://jasperforge.org/website/jasperreportswebsite/trunk/getting.started.html?group_id=252

    It will be useful.
