Text is very fuzzy!!! Hello all, I create one Bitmap and put one image on it. On this Bitmap I have also some Information as text. This Text is very Fuzzy. Does anybody know, how can I print a bitmap with text with higher resolution? maybe know TeamB or Gambit a solution. thanks ------------------------------------------------------------------------------------------------- // Code sample Graphics::TBitmap *bmpReport; bmpReport = new Graphics::TBitmap; bmpReport->Canvas->Font->Name = "Tahoma";//true type bmpReport->Canvas->Font->Size = 8; // Size does not matter it is always fuzzy. .... int h = anotherBitmap->Height; int w = anotherBitmap->Width; BitBlt(bmpReport->Canvas->Handle,1,1,w,h+1,anotherBitmap->Canvas->Handle,0,0,SRCCOPY); //Put Information on Bitmap sprintf(Buffer,"Max: %s Min: %s",chMax,chMin); bmpReport->Canvas->TextOut(X,Y,Buffer); .... and some more information. ------------------------------------------------------------------------------------------------ If I print now my Bitmap, the written Text has very poor quality. The resolution of text in bitmap is not satisfactorily. The text border is very fuzzy and looks a bad copy. Tanks in advance I use Builder 6.0 Back to top Hans Galema Guest Posted: Tue Feb 13, 2007 9:32 pm    Post subject: Re: Printed Bitmap with Text on it. Text is very fuzzy!!!

Please provide the contents for anotherBitmap in a file and post that to borland.public.attachments. Post also the resulting bitmap. In this way people can experiment with/for you. Hans.

I print the Bitmaps using Quickreport. But if I print it also with another programm e.g. Color Draw, the result is the same. I think I have to search for a way to create the bitmap with a higher resolution. thanks in advance for youtr help Back to top JD Guest Posted: Thu Feb 15, 2007 5:11 am    Post subject: Re: Printed Bitmap with Text on it.

The problem may be with your font selection and I'd also expect that you're not taking into account the difference in DPI between the screen and the printer. I also see that you're using QR (yuck) so I have no clue if it stretches or does a straight blt but if it's stretched, that could also be the problem. ~ JD Back to top Shapour Guest Posted: Thu Feb 15, 2007 9:10 am    Post subject: Re: Printed Bitmap with Text on it.

I create the Bitmaps like following: ----------------------------------------- bmpReport = new Graphics::TBitmap; bmpTemp = new Graphics::TBitmap; bmpReport->PixelFormat = pf24bit; bmpTemp->PixelFormat = pf24bit; bmpReport->HandleType = bmDIB; bmpTemp->HandleType = bmDIB; ------------------------------------------ The Images on Quickreport has the same size as created Bitmap. strech is set to false. I test it also with another fonts. (Arial, san serif...) but the result was always the same. I will check the DPI on printer. thanks Shapour Back to top JD Guest Posted: Thu Feb 15, 2007 10:43 pm    Post subject: Re: Printed Bitmap with Text on it. Text is very fuzzy!!!

You can't just do a pixel per pixel copy because the printer DPI will *always* be higher than that of the screen. If you want it to look the same on the paper as it does on- screen, you need to use the win32 GetDeviceCaps to get the number of pixels per inch for the screen's X and Y. When you have that, do some math to get the width and height of the bitmap in inches. Then get the printer's pixels per inch for it's X and Y and calculate a TRect into the printer that represents the same size in inches as the bitmap. Finally, since the destination Rect will be larger than the source, you need to stretch it. If you still experiance problems, then I would suggest that you not set the bitmap's HandleType to bmDIB because I've never used it because I've always manually converted it and that has always worked. ~ JD Back to top MR Guest Posted: Sun Feb 18, 2007 3:15 pm    Post subject: Re: Printed Bitmap with Text on it. Text is very fuzzy!!! Hello JD, thank you for your detailed explanation! I think also, that this is the problem. because the printer has a higher resolution as screen. so I try to follow your suggestion. thanks Shapou Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         BorlandTalk.com Forum Index -> C++ Builder (Graphics) All times are GMT Page 1 of 1   Jump to: Select a forum C++ Builder Newsgroups----------------C++ BuilderC++ Builder (ActiveX)C++ Builder (Announcements)C++ Builder (Command Line Tools)C++ Builder DatabasesC++ Builder Databases (ADO)C++ Builder Databases (Desktop)C++ Builder Databases (InterBase Express)C++ Builder Databases (Multi-Tier)C++ Builder Databases (SQL Servers)C++ Builder (Graphics)C++ Builder (IDE)C++ Builder (Internet)C++ Builder (Internet Socket)C++ Builder (Internet Web)C++ Builder (Jobs)C++ Builder (Language)C++ Builder (Language C++)C++ Builder (Compatibility with MFC)C++ Builder (Native API)C++ Builder (Non-Technical)C++ Builder (Students)C++ Builder (Third Party Tools)C++ Builder (Upgrade)C++ Builder (VCL)C++ Builder (VCL Components Usage)C++ Builder (VCL Components Development)C++ Builder (VCL Usage)C++ Builder (WinAPI)C++ Builder Installation Delphi Newsgroups----------------Delphi (General)Delphi ActiveX Controls UsageDelphi ActiveX Controls DevelopmentDelphi As400Delphi DatabasesDelphi Databases (ADO)Delphi Databases (dbExpress)Delphi Databases (Desktop)Delphi Databases (InterBase Express)Delphi Databases (Multi-Tier)Delphi Databases (SQL Servers)Delphi DeploymentDelphi GraphicsDelphi IDEDelphi InternationalizationDelphi InternetDelphi Internet Isapi-WebBrokerDelphi Internet WebSnapDelphi Internet WinsockDelphi JobsDelphi Language BASMDelphi Language ObjectPascalDelphi Model Driven Architecture (General)Delphi Model Driven Architecture (Third Party)Delphi MultimediaDelphi Native APIDelphi Non-TechnicalDelphi ObjectPascalDelphi OLE AutomationDelphi OO designDelphi OpenToolsAPIDelphi Reporting-ChartingDelphi RTLDelphi StudentsDelphi TeamSourceDelphi Thirdparty ToolsDelphi Thirdparty Tools (General)Delphi Thirdparty Tools (IntraWeb)Delphi Thirdparty Tools (RaveReports)Delphi UpgradeDelphi VCLDelphi VCL ComponentsDelphi VCL Components UsingDelphi VCL Components WritingDelphi WebServices SOAPDelphi WinAPIDelphi XMLDelphi Installationcomp.lang.pascal.delphi.components.misccomp.lang.pascal.delphi.components.usagecomp.lang.pascal.delphi.components.writingcomp.lang.pascal.delphi.databasescomp.lang.pascal.delphi.misccomp.sources.delphi JBuilder Newsgroups----------------JBuilderJBuilder AnnouncementsJBuilder Applet IssuesJBuilder As400JBuilder CompilerJBuilder CORBA/RMIJBuilder DatabasesJBuilder DB SwingJBuilder DebuggerJBuilder DeploymentJBuilder DocumentationJBuilder EnterpriseJBuilder HandheldJBuilder IDEJBuilder JavaJBuilder JavaAPIJBuilder Java LanguageJBuilder Java SwingJBuilder Java BeansJBuilder Java Beans UsageJBuilder Java Beans DevelopmentJBuilder JBCLJBuilder JDataStoreJBuilder JobsJBuilder LinuxJBuilder MacintoshJBuilder & MobileSetJBuilder MultiLingual AppsJBuilder Non-TechnicalJBuilder OpenToolsJBuilder Servlets (JSP)JBuilder StudentsJBuilder Team DevelopmentJBuilder Thirdparty ToolsJBuilder UpgradeJBuilder Installation InterBase Newsgroups----------------InterBaseInterBase Bug DiscussionInterBase GeneralInterBase IBConsoleInterBase OpenSourceInterBase ReplicationInterBase SQLInterBase ThirdpartyInterBase Installation Miscellaneous Borland Newsgroups----------------AppCenterAppServerEnteraVisiBroker  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum Powered by phpBB © 2001, 2006 phpBB Group SEO toolkit © 2004-2006 webmedic.
