TeeChart's TeeSaveToPDFFile function does not work reliable, since a random gap is drawn between characters of text. Only if this gap is 0, output is OK. Inspecting the source code, I found the following lines in TeePDFCanvas.pas, in the procedure TPDFCanvas.RotateLabel(x,y:Integer; Const St:String; RotDegree:Double): if Assigned(IFont) then WriteStringToStream(FCStream,FontProperties(IFont,FontIndex)+' ') else WriteStringToStream(FCStream,FontProperties(TTeeFont(Font),FontIndex)+' '); The last line is critical, since it misses a dynamic type check whether Font is actually a TTeeFont. If Font is not a TTeeFont, the Font's InterCharSize property returns a random value in function FontProperties which causes the random gap to be drawn. I would suggest to add the dynamic type check and overload function FontProperties accordingly. http://www.teechart.net/support/viewtopic.php?f=3&t=12930&p=56084#p56084 [created:2012-01-09T15:29:20.000+01:00 reported by:yeray@steema.com reported in version:2011.04.41118 (TeeChart VCL)]
