Image size in ColumnText

native.human — 2008-12-01T21:11:01

I am using ColumnText.addElement to add an Image object that I have run scalePercent on. It seems to be ignoring my scaling and making the image the width of the entire column. Seems like it might have to do with text mode vs. compsite mode, but I think I'm in composite mode. My code looks like this, and previous to this code is a call to ct.go(), so there's nothing else in the column but the image at this point: imgGraph.scalePercent(50); imgGraph.setAlignment(Image.LEFT); /* * Add chart for simulated render */ ct.addElement(imgGraph); /* * Start new page if necessary. */ handleOrphans(ct, document, columnTop); /* * Add chart again, because handleOrphans only simulates * render. */ ct.addElement(imgGraph); /* * Actual render, handling paging as necessary */ handlePaging(ct, document, columnTop, "Highlight graph"); handleOrphans looks like this: protected void handleOrphans(ColumnText ct, Document document, float columnTop) throws DocumentException { /* * Position to render at. Default to position before the render. */ float position = ct.getYLine(); /* * Pretend to render column */ int status = ct.go(true); /* * If it doesn't all fit... */ if (ColumnText.hasMoreText(status)) { /* * Clear column contents in case there's content still in there. */ ct.setText(null); /* * Start new page */ document.newPage(); /* * Set position to top of page */ position = columnTop; } /* * Set position to top of page */ ct.setYLine(position); } and handlePaging looks like this: protected void handlePaging(ColumnText ct, Document document, float columnTop, String description) throws DocumentException { /* * Page count. */ int pageCount = 0; /* * Max out at 100 pages to prevent an infinite loop. */ final int maxPage = 100; /* * Render column */ int status = ct.go(); /* * If there's more text, start a new page and continue. */ while (ColumnText.hasMoreText(status) && pageCount < maxPage) { /* * Start new page */ document.newPage(); /* * Move column position to top of page */ ct.setYLine(columnTop); /* * Render again */ status = ct.go(); } }

iText is not a FOP engine. However, it is the library that is used in several FOP engines, such as the one in RenderX. ---mr. bean ntimesc wrote:

epsg entry in gcs dictionary?

Matthias Uhler — 2008-12-01T16:03:46

hi, when i choose a wkt string for WGS84 as entry in a geographic coordinat system dictionary (iso 32000 supplement, p. 51) like this: dictionaryGCS.put(new PdfName("WKT"),new PdfString("GEOGCS[...]")); The georeferencing works great! Instead of using an wkt string I tried to change the entry to an EPSG-code: dictionaryGCS.put(new PdfName("EPSG"),new PdfNumber("4326")); //EPSG of wgs84 This doesn't work! I tried also other epsg codes without any success. Do you have any idea or hints how to put the code for a working PDF? Thank you, Matthias

Re gistering files at point of usage instead of via RegisterDirectories

mister bean — 2008-12-01T01:40:54

On systems with many font files, the RegisterDirectories() method can take a while to run. I'd like to be able to provide a property file that contains the font family names and the file locations. Then, when the doc refers to a font, look it up in the property file, get the path to it and register the font file right then and there. To create this property file, I recursively go through a list of font directories. The problem is that iText does not let me access the family name/font name and location for the files it registers. I can get the font names via the iterator (p. 274 in the book) or the font family (different iterator, same page), but I cannot get the font name, family, and file location from iText, as the needed fields in the source code are private. Any suggestions on how to create this property file? Thanks ahead of time for any help. ---mr. bean

Help needed with setCharAdvance andsuperscript/subscript.

Ian Hobson — 2008-11-30T21:42:38

Hi all, What I am trying to do is to print Specific Optical Rotations These are written as an alpha character inside brackets ( [a]) which has BOTH a) A temperature as a super script (usually 20). Together with b) A letter (A to F) as a sub-script. (usually D). I am using Arial font and trying to be system neutral by using FontFactory. Normal text is 9 pt, and the sub and super-scripts are 6pt, lowered or raised by 4.0f. So far everything is exactly as expected. I am writing the sub-script first, so what appears has the superscript too far to the right. I want to put the superscript above the sub-script, so it belongs to the "]". The code is too big to copy here in its entirety (it is reading a RTF, building tables and all sorts). The key parts are I am building a paragraph p from a rich text field. I have found both sub and superscript. Font dummy = FontFactory.getFont("Arial"); BaseFont bf = dummy.getBaseFont(); String subrun = "D"; // subscript for example (always one letter). String superrun = "20"; // superscript for example int oldwidth = bf.getWidth(ch); bf.setCharAdvance(ch, -100); Font subfont = new Font(bf,6); Chunk bit = new Chunk(subrun ,subfont); bit.setTextRise(-4.0f); p.add(bit); bf.setCharAdvance(ch,oldwidth); // see note about this line subfont = new Font(bf,6); bit = new Chunk(superrun ,subfont); bit.setTextRise(4.0f); p.add(bit); p is then added to a cell which is added to a table. This code may be repeated for later cells, or skipped if there is no optical rotation to report. With the line indicated commented out the result is that every D that appears in other cells - even those created before this code is executed, are over-written by the next character! With it present as shown the super-script is positioned to the right of the sub-script. I suspect that the setCharAdvance alters the embedded font, so that either all "D"s or no "D"s have their Advance altered. How can I achieve what I want to achieve?

Re: Which image type is more resource/memoryhungry with iText?

Leonard Rosenthol — 2008-11-28T15:19:02

Forget "resource hungry" - consider what you are working with. a JPEG image is for PHOTOGRAPHS (that's what the P in JPEG stands for, after al) and should NOT be used for contone images that include text or vector data. PNG is a general purpose image format and as such is much better suited for contone images.

Filled edges not as clear as stroked edges

Carpo — 2008-11-27T23:29:24

Hi, I've created a function that draws a border around a rectangle. Each border of the rectangle can have border styles similar to css border styles (Dotted, dashed, grooved, ridged etc) as well as different colors and widths. Because of this, my function draws each border side of the rectangle separately (top, then right etc ...), either as a solid filled rectangle, or as a pattern filled rectangle (for dotted, ridged etc). The problem I have is that the edges of a solid shape don't look as crisp in the acrobat viewer as a standard stroked rectangle. I've tried a few viewers, and they all look a little blurred. Standard stroked rectangles have a crisp, clean edge in the viewers ... but I can't get that same look. However, when printed it looks fine. Also, if zoomed to about 300% it looks fine in the viewer. I guess i was wondering if there is a setting that may help make the edges of a filled shape look crisper, or if anyone has any ideas on why this is happening? Any help would be great.
