How to skip new line character, if it is already present?
In my case, if my text in database is in this format:
Relative to the ground, an airplane
gains speed when it encounters wind
from behind.
So i have to write in my pdftable column in one line as much space avalible in the column.
You have to set the setNoWrap() true in order to achieve this.
Try something like this
Phrase p1=new Phrase("Relative to the ground, an airplane gains speed when it encounters wind from behind.", FontFactory.getFont(FontFactory.TIMES_ROMAN,8));
PdfPCell cell1=new PdfPCell(p1);
cell1.setNoWrap(true);
Also note that if your column size is less then the text will exceed your cell.

Alright, I do not know how to fix this and only ran into this problem after trying to put in some longer text on a UI Text component. I have tried both pasting a value into its Text attribute through the Unity editor, and setting its value programmatically like this:
t.GetComponent<Text> ().text = "This is where meat, fish, and [...] (long text)"
Because Horizontal wrap is on, the text wraps when it reaches the edge of the available space.
However, the text displays backwards. Meaning, the start of the paragraph is at the bottom, and bottom at the top. Taking off wrap fixes this, but then the font size has to be really small (or it won't all be visible), and it can't form a normal paragraph because it has to... you know... wrap.
Is this a bug in Unity?
This is what happens - as you can see, it is displayed backwards:
The negative Line Spacing value is what is causing the issue here:
When the value of this field is less than 0, the lines will actually be arranged backwards, leading to the behaviour you're currently encountering. Just change the value to a positive number to have the text display correctly.
I would like to have a text box rescale with the level of magnification, such that one unit of text is always assigned one unit of horizontal axis-length. The text width should not change but rather the spacing between characters.
For instance, if the x-axis displayed [0:50], fifty characters should be displayed, one at each integer position. If the magnification was increased such that the display comprised only [0:10], only ten characters would be displayed, again placing one character at each integer position along the horizontal axis.
Finally, the text would ideally not display when the magnification level was below some threshold determined by the number of characters that can be legibly printed along a horizontal line spanning the extent of the axes.
I have tried using the text object, but it doesn't seem to have the relevant properties to allow such dynamic behavior. I have instead considered breaking the N-length string into N unit-length strings and placing each at a defined x-position, but I'm having trouble figuring out how to display only those relevant at the prevailing zoom level (there is some spill-over of characters beyond the bounds of the axis). In contrast, with this approach, all the characters appear as a jumble at zoom levels so low that the number of characters printed cannot be reasonably accommodated.
Thus, I inquire whether another solution besides printing a series of unit-length strings might be advised and, if not, how the twin problems of text spill-over and text overlap can be resolved at high and low zoom, respectively (the first might be done by somehow preventing printing of information outside the axes; the second seems to require some dynamic magnification-aware means of suppressing text output at or above a certain x-axis extent).
I am drawing text in a PDF page using iTextSharp, and I have two requirements:
1) the text needs to be searchable by Adobe Reader and such
2) I need character-level control over where the text is drawn.
I can draw the text word-by-word using PdfContentByte.ShowText(), but I don't have control over where each character is drawn.
I can draw the text character-by-character using PdfContentByte.ShowText() but then it isn't searchable.
I'm now trying to create a PdfTextArray, which would seem to satisfy both of my requirements, but I'm having trouble calculating the correct offsets.
So my first question is: do you agree that PdfTextArray is what I need to do, in order to satisfy both of my original requirements?
If so, I have the PdfTextArray working correctly (in that it's outputting text) but I can't figure out how to accurately calculate the positioning offset that needs to get put between each pair of characters (right now I'm just using the fixed value -200 just to prove that the function works).
I believe the positioning offset is the distance from the right edge of the previous character to the left edge of the new character, expressed in "thousandths of a unit of text space". That leaves me two problems:
1) How wide is the previous character (in points), as drawn in the specified font & height? (I know where its left edge is, since I drew it there)
2) How do I convert from points to "units of text space"?
I'm not doing any fancy scaling or rotating, so my transformation matrices should all be identity matrices, which should simplify the calculations ...
Thanks,
Chris
i would like to create a conditional keeptogether property depending on the space left on the current page, is it possible to get this value from within a formula field?
my goal is a visual clean report without wasting to much space, i already read about a method where you keep track of your position with a linenumber counter. unfortunately i cant use this approach because my lines vary heavy in height because of a note field which holds from 0 to 25 lines.
This is going to sound like a ridiculous and tedious suggestion, but it's the only way I know of making this work. You'll need to use that process of line counting (basically, keeping a running total of how many lines have been printed) that you heard of with one modification: calculate the number of lines Notes needs by the getting the length of that Notes string and dividing by a pre-determined count, which you'll need to do visually, of how many characters are in a line and make the result the line's line count in the overall formula. It's not going to be exactly right because there is no way to make it exactly right, but it will be close. Does that makes sense or do you need me to go into exact detail of how to do this?
I'm looking for a font which contains a graphic character which is (essentially), the space character, inverted. I'm looking for a graphic character equivalent to the largest-possible solid-black box. The closest I have been able to find is Wingings 2 character 162, but that doesn't fill the entire available character space. When I insert two consecutive Wingdings 2 162 characters, there is still appreciable whitespace between them when displayed or printed. Does anyone know of a black-box font/character which would fill all available character space?
All characters are going to have whitespace between them, or they would be unreadable. This is called "kerning". You can adjust the kerning and line-height in whatever program you are using to send the malicious fax, if you want to be sure to use the maximum amount of toner per page.
Have you considered creating your own font using a software package like this or like this? You could edit the space character to be a solid black square. But as Chris McCall mentioned, you may still have space between characters of any size due to kerning applied by the layout engine that draws the fonts.
You other option is to owner draw your own text and programmatically replacing spaces with black boxes. You would have complete control over kerning and everything else.
I don't know if this is exactly what you were looking for, but...
I was looking for the same thing, since I wanted to create a "textbox" when I wanted to write text using the spritefont, but I never knew how long the total string was going to be, so I wanted something that I could "write" in the same location right before the string with a contrasting color which could be expected to be as long as the string it needed to encompass. That being the case, try:
Webdings - character 103.
I tried lining them up and there wasn't even any space in between. Perfect.
