I'm using borland c++ builder 2006. I would like to create a list of jpeg images and I only found the class ImageList that process only bitmap and icons.. Any suggetion? Thanks Back to top Clayton Arends Guest Posted: Tue Sep 26, 2006 8:40 pm    Post subject: Re: List of Jpeg images If you don't need the list to be a component like TImageList then you can create a list of JPEGs using either the standard template library (STL) class std::list or the VCL TObjectList class. If you need the list to be a component like TImageList, to be able to add/remove images at design-time, then you will need to write a component or find a third-party solution. I have created a similar component that works with TPicture and TGraphic objects. TGraphic is the parent class of all image classes like TJPEGImage. TPicture is a class that works with TGraphic classes without the developer needing to know the exact type of the class. Which approach do you think you would prefer? - Clayton Back to top Daniel Schoeni Guest Posted: Sun Jan 07, 2007 5:29 am    Post subject: Re: List of Jpeg images Hi Quote: 2006. I would like to create a list of jpeg images and I only found the class ImageList that process only bitmap and icons.. jpegs are bitmaps. so you open your jpegs with Image1->Picture->LoadFromFile(FilePathInfo); every Image in your ImageList must have the same size ! so if you have different sizes you first need to process it. I used to copy it to a second image after calculating some parameters: Image2->Canvas->StretchDraw(Rect(XOfs,YOfs,XOfs+XSize,YOfs+YSize), Image1->Picture->Graphic ); then I added it to the ImageList: ImageList1->Add(Image2->Picture->Bitmap, NULL); don't forget: #include <jpeg.hpp> sincerly Daniel Back to top Remy Lebeau (TeamB) Guest Posted: Wed Jan 10, 2007 12:57 am    Post subject: Re: List of Jpeg images "Daniel Schoeni" <daniel.schoeni (AT) bluewin (DOT) ch> wrote in message news:45a030a0 (AT) newsgroups (DOT) borland.com... Quote: jpegs are bitmaps. No, they are not. Quote: so you open your jpegs with Image1->Picture->LoadFromFile(FilePathInfo); Being a bitmap or not has no effect on that. TPicture supports any image format that a TGraphic-derived class is available for. The VCL has such classes available for BMP, ICO, WMF, EMF, and JPG images by default. Quote: every Image in your ImageList must have the same size ! so if you have different sizes you first need to process it. You can't load JPG images into a TImageList. It can only load BMP and ICO images.

No, they are not. Hmm, that's arguable. Basically, there are two types of graphics: bitmap graphics and vector graphics. A jpeg is definitely not a vector image, it's a compressed bitmap. But I agree that for BCB, jpeg aren't Bitmaps as far as type is concerned. Michel -- ---------------------------------------- Michel Leunen mailto: see my homepage.

To be completely accurate that should read "raster graphics and vector graphics". If you want to make the case that raster = bitmap you can. Personally, I'm in the camp that believes bitmap = the BMP file/memory format. - Clayton 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.
