Hi, I am actually using iTextSharp, but I don't know if this problem is specific to iTextSharp or is a general problem (or misunderstanding by me) of iText. I am working with some embedded fonts that don't have italic options. So, to get around this, I am doing a skew transformation, and the italicization looks ok. But it is offsetting the x value as well, even though I am passing 0 for x and y (e and f) values in my matrix. In other words, I am doing something like this:
float x = 28F; float y = 100F; float italicization = xFontSize / 100F; Matrix m = new Matrix(1F, 0F, italicization, 1F, 0F, 0F); cb.Transform(m); cb.ShowTextAligned(0, Content[i].Trim(), x, y, 0F); m = new Matrix(1F, 0F, 0F-italicization, 1F, 0F, 0F); cb.Transform(m); cb.ShowTextAligned(0, Content[i].Trim(), x, y, 0F); so, first I write the string (Content[i]) in pseudo-italics, then transform back to original and write it un0-italicized for comparison. The offset varies, but depending (I think) on font size and maybe also on string length, the offset is by 2 to 6 characters. I have been trying many combinations of italicization values, offsetting x by variable amounts, and so on, but I can’t get this to come out right. I also tried this but it does exactly the same thing.: Matrix m = new Matrix(1F, 0F, italicization, 1F, x, 0F); cb.Transform(m); cb.ShowTextAligned(iAlign, Content[i].Trim(), 0F, y, 0F); m = new Matrix(1F, 0F, 0F-italicization, 1F, 0F-x, 0F); cb.Transform(m); cb.ShowTextAligned(iAlign, Content[i].Trim(), x, y, 0F); Interstingly,m I had this working, sort of – I was just doing this: cb.ConcatCTM(1F, 0F, italicization, 1F, 0F, 0F); cb.SaveState(); cb.ShowTextAligned(0, Content[i].Trim(), x, y, 0F); cb.RestoreState(); and this was giving me good results, but was then causing a PDf error: Illegal operation 'Q' inside a text object. (this all happens inside a beginText()-endText() block, which I guess is not ok). Does anyone have any ideas about this? I am going crazy. I can give you more info as needed – I tried to give enough, but maybe not… Thanks, Ian -- View this message in context: http://www.nabble.com/pseudo-italic-%28transform%29-causing-horizontal-offset-tp19533150p19533150.html Sent from the iText - General mailing list archive at Nabble.com. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ iText-questions mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/itext-questions Buy the iText book: http://www.1t3xt.com/docs/book.php
