• How to remove the text areas of a scanned document

  How can I remove a plethora (sp?) of the text areas of a scanned document?

  Hello JBreeden,

  More scanned documents cannot be changed, unless you have a software that can read digital information. The scanned document is just a picture of the item that you have scanned. You must have a software like OCR (optical character recognition) to be able to make changes to the digitized item.

  Thank you

• How to clear the text on the image

  Hello

  I have a screen with the background image (bitmap). I draw the text and other images on this background to aid graphics object and all looks ok when I show the screen - but only the first time because the next time background image is one containing all these designs on it.

  I would like to know if it is possible to erase these drawings, so next time I can use background image to draw top again?

  I use something like this:

  String fText = "Text";
  

  fBackground = Bitmap.getBitmapResource("background.png")
  
  fGraphics = new Graphics (fBackground );
  
  fvm1 = new VerticalFieldManager()
  {     
  
  public void paint(Graphics graphics)
  {
     fGraphics.drawText(fText, 0, 0);
  
     graphics.drawBitmap(0, 0, fBackground.getWidth(),  fBackground.getHeight(), fBackground, 0, 0);
  
     super.paint(graphics);
  }
  }
  

  Next time I want to draw text 'Text2' so I change variable fText to "Text2". How can I remove the 'Text' text before doing this?

  Thanks in advance.

  You really want to paint on the bitmap background to show change data.

  One of the most obvious solutions is to have fields for that--both the LabelField and RichTextField are good for displaying text, BitmapField is good to display bitmaps (use setBitmap to change the image), GaugeField is ideal for the indication of the percentage, etc..  Add the fields to your VerticalFieldManager, use the margins and the bits of style such as FIELD_HCENTER to space and position them the way you want and enjoy. When comes a new value to display, change the field matching and nullity. This is the right way to do these things.

  Of course-, since you seem to be attached to the use of the graphics directly - the quick and dirty approach is just to paint directly on the screen using the Graphics object passed in object.  Something like this:

  fBackground = Bitmap.getBitmapResource("background.png")
  
  // fGraphics = new Graphics (fBackground );
  
  fvm1 = new VerticalFieldManager()
  {     
  
  public void paint(Graphics graphics)
  {
     // fGraphics.drawText(fText, 0, 0);
  
     graphics.drawBitmap(0, 0, fBackground.getWidth(),  fBackground.getHeight(), fBackground, 0, 0);
     graphics.drawText(fText, 0, 0); // plus any other draws...
     super.paint(graphics);
  }
  }
  

  Of course, you must also override sublayout() to this VerticalFieldManager to properly define its dimensions.

  However, doing it this way is really strange. You must be something much simpler than a VerticalFieldManager to paint in it (expand, replace its layout() setExtent() correctly and his object to do any painting you need - do not call the super.paint (), it is abstract) or you add fields to it as usual and let the super.paint () do its job.

• How to clear the text drafted the Bitmap by graphics.drawtext (...) (try to do a count down on top of the Bitmap)

  Hello, I'm doing a count down on top a Bitmap image. I use graphics.draw (),
  However, this ended up writing the text on text, no matter what I do.
  Example: when the second = 3, the image will be 3 shot
  When the second = 2, the image will be 2 on top 3 drawn on it (in this case 3 does not appear)
  When the second = 1, the image will be 1 of 2 on top 3 drawn on it (in which case 2.3 does not appear)

  Can anyone help please, thanks in advance... Here is the code:

  Timer each who calls every second {...
  {Synchronized (UiApplication.getEventLock ())}
  Bitmap temp = BitmapOriginal;
  Graphics g = Graphics.create (temp);

  Font myFont = Font.getDefault ().derive(Font.BOLD,13);

  StartcountDown.setFont (StartcountDown.getFont () .derive (Font.BOLD, 15, Ui.UNITS_pt));

  int xOffset = (int) ((BitmapOriginal.getWidth () / 2)-(Font.getDefault().getAdvance(Integer.toString(startCountDown))/2)); (temp.getWidth () - Font.getDefault () .getAdvance (Integer.toString (startCountDown)));
  int decalage_y = (int) ((BitmapOriginal.getHeight () / 2)-(Font.getDefault().getHeight()/2)); (temp.getHeight () - Font.getDefault () .getHeight ());

  g.setColor (Color.WHITE);
  g.setFont (myFont);

  g.Clear ();

  g.drawBitmap (0, 0, BitmapOriginal.getWidth (), BitmapOriginal.getHeight (), BitmapOriginal, 0, 0);
  g.drawText (Integer.toString (startCountDown), x_offset, decalage_y);

  PicAndText.setBitmap (temp);
  }
  ... }

  You can't disable text written on Bitmap. However, you don't have to write the text on the original. This:

  Bitmap temp = BitmapOriginal;

  won't. You copy not the original - you get a reference to it.

  Something like that

  Bitmap temp = new Bitmap(BitmapOriginal.getWidth(), BitmapOriginal.getHeight());
  Graphics g = Graphics.create(temp);
  g.drawBitmap(0, 0, temp.getWidth(), temp.getHeight(), BitmapOriginal, 0, 0);
  

  copies BitmapOriginal in temp, leaving intact and ready for the next use. The trick is to create a new bitmap every time to handle.

• How to integrate the text when exporting to PDF?

  Hi, I have installed a font called "AddCityBoy" and used throughout my entire project. When I went to export it to PDF, it gave me an error message, but I tried again in any case. When I opened the PDF on a Mac, (I used windows beforehand), the text was in a different font. Already, I went to the "Advanced settings" and ensure that "subset fonts when the percentage of characters used is less to ' was set at 100%. I don't know what else to do! Help, please!

  Some fonts are protected and do not allow you to nest them. You can work around this by converting them into vector art by selecting the text image (s) and in the menu, choose Type > vectorize. So you will be no longer able to edit the text, save an original copy of the document before you convert, in case you want to change things after you export.

• How to bind the form field in two pdf documents

  Is there a way to link two form fields. 1 document allows the reader to enter the text in the field. However, I would like any document 2 to display the text as well. Is this possible?  Please notify.

  Hi lysaj85192398,

  There is no direct function that can perform this task. But I'm sure you can do this with JavaScript.

  Take a look at this: transfer to another PDF form fields?

• How can I change the page size of a pdf document so that I can check on my iphone more clearly?

  How can I change the page size of a pdf document so that I can check on my iphone more clearly?

  This is way beyond what can be done with PDF, except by copying the text and make a new document in Word or something.

  That said, Adobe Reader on Windows may display the text AS IF the PDF file has been divided. It's the text reformatting. It may be possible in Reader for iPhone, you can try the player for ios forum.

• How to make the text in the header change with scrolling effects?

  Im trying to do a header which changes when you scroll the page. I know how to make the text scrolls and back according to the key position, but his does not work if my key is less than my position of text on the page.

  Ideally, I would like to get so that I scroll to the area of 'Wine', the previous header will slide out and 'Wine' will slide in from the left.

  Any ideas?

  Thank you

  Try this then and you can replace the blur with an event of jquery as you like

  $("#P16_ENG_CTRY").blur(function() {
  //clear the value
    if ($(this).val()==null || $(this).val()=="") {
       $("#P16_ENG_STATE").val('');
    }
   }
  });
  

• How to make the text field change every 5 seconds?

  Hello

  I intend to create a "credit movie" intro with a list of names of 50-100, one name at a time centered on the screen. Is there a script that will take the words of a text file (or the text pasted into a Word document in a model) and break up so that only one name appears every 5 seconds or so? I try to avoid typing each time and have 50 + layers of text.

  Thank you!

  Craig

  • Put your credits in a document from the text editor.
  • Calculate your longest line of text.
  • Make a text layer.
  • Coller, paste in the longest line in the desired font, and then type the size.
  • Twirl in the triangle of text on the text layer properties.
  • Make a keyframe on the Source text property.
  • Go five seconds to the bottom of the timeline.
  • Double-click the text layer and paste it into the new text; you see the new text and another Source text keyframe.
  • Repeat as many times as necessary.

  Don't forget to delete the first key Source text frame, you did.  It just was, for purposes of composition.

• How to get the text have the same effect as the video?

  Hello

  For the first time post here, but I wonder how to get the text of the titles have the same effect as the video behind her.

  For my video, I use 'bad tv' and other effects such as Gaussian that obviously changes the appearance of video, creating the look of VHS. However, I then inserted text via the title, but it normally appears. How can I make this text have the same effects as the video behind it?

  A friend told me I might need to add text to the video first, then do the effects, I have not tried, but wonder if there is an easier way, as this would require me to restart.

  EDIT: That's what I'm looking for. https://youtu.be/7_2PHQI89dI?t=24s The text has the same effect as the video.

  Thank you

  One way is to create a clip made up based on the title and the original clip. Then apply the effect.

  Another way is to use an adjustment layer.

  Good luck.
