下載TeeChart Pro ActiveX最新版本

本教程概述了以各種格式導(dǎo)出TeeCharts并導(dǎo)入TeeChart自己的.ten格式圖表模板。

導(dǎo)出圖表

可用格式

可用導(dǎo)出格式。可以將所有格式復(fù)制到文件或剪貼板或Stream。

圖像格式

• BMP：BitmapFormat類
• JPEG：JPEGFormat類
• WMF和EMF：MetafileFormat類
• GIF：GIFFormat類
• PNG：PNGFormat類
• TIFF：TIFFFormat類

數(shù)據(jù)格式

• Text：TextFormat類
• XML：XMLFormat類
• HTML：HTMLFormat類
• Excel：ExcelFormat類

其他格式

ten格式是一種靈活的格式，可存儲(chǔ)圖表屬性信息和（可選）圖表數(shù)據(jù)。文件很小（取決于數(shù)據(jù)），非常適合網(wǎng)絡(luò)用于更新基于實(shí)時(shí)客戶端的圖表。

• TEN（TeeChart）：TemplateExport類

示例導(dǎo)出

導(dǎo)出到文件是合理的，在大多數(shù)情況下，您只需要定義目標(biāo)文件名。

[C＃]

private void button1_Click(object sender, System.EventArgs e)  
            saveFileDialog1.Filter = "Images (*.bmp)|*.bmp|Images(*.jpg)|*.jpg|Images(*.wmf)|*.wmf|Images(*.emf)|*.emf|Images (*.gif)|*.gif|Images (*.png)|*.png|Images (*.tiff)|*.tiff"; 
            saveFileDialog1.ShowDialog(); 
            if(saveFileDialog1.FileName != "")  
                switch(saveFileDialog1.FilterIndex)  
                    case 1: 
                        tChart1.Export.Image.Bitmap.Save(saveFileDialog1.FileName); 
                        break; 
                    case 2: 
                        tChart1.Export.Image.JPEG.Save(saveFileDialog1.FileName); 
                        break; 
                    case 3: 
                        tChart1.Export.Image.Metafile.Enhanced = false; 
                        tChart1.Export.Image.Metafile.Save(saveFileDialog1.FileName); 
                        break; 
                    case 4: 
                        tChart1.Export.Image.Metafile.Enhanced = true; 
                        tChart1.Export.Image.Metafile.Save(saveFileDialog1.FileName); 
                        break; 
                    case 5: 
                        tChart1.Export.Image.GIF.Save(saveFileDialog1.FileName); 
                        break; 
                    case 6: 
                        tChart1.Export.Image.PNG.Save(saveFileDialog1.FileName); 
                        break; 
                    case 7: 
                        tChart1.Export.Image.TIFF.Save(saveFileDialog1.FileName); 
                        break; 

[VB.Net]

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click 
        SaveFileDialog1.Filter = "Images (*.bmp)|*.bmp|Images(*.jpg)|*.jpg|Images(*.wmf)|*.wmf|Images(*.emf)|*.emf|Images (*.gif)|*.gif|Images (*.png)|*.png|Images (*.tiff)|*.tiff" 
        SaveFileDialog1.ShowDialog() 
        If SaveFileDialog1.FileName <> "" Then 
            Select Case SaveFileDialog1.FilterIndex 
                Case 1 
                    TChart1.Export.Image.Bitmap.Save(SaveFileDialog1.FileName) 
                Case 2 
                    TChart1.Export.Image.JPEG.Save(SaveFileDialog1.FileName) 
                Case 3 
                    TChart1.Export.Image.Metafile.Enhanced = False 
                    TChart1.Export.Image.Metafile.Save(SaveFileDialog1.FileName) 
                Case 4 
                    TChart1.Export.Image.Metafile.Enhanced = True

導(dǎo)出圖片

BMP

BMP文件導(dǎo)出具有顏色和大小的附加參數(shù)，例

[C＃]

case 1: 
     Steema.TeeChart.Export.BitmapFormat bitMap = tChart1.Export.Image.Bitmap; 
     bitMap.Height = 500; 
     bitMap.Width = 700; 
     bitMap.Monochrome = true; 
     bitMap.Save(saveFileDialog1.FileName); 
     break; 

[VB.Net]

Case 1 
     Dim BitMap As Steema.TeeChart.Export.BitmapFormat = TChart1.Export.Image.Bitmap 
     BitMap.Height = 500 
     BitMap.Width = 700 
     BitMap.Monochrome = True 
     BitMap.Save(SaveFileDialog1.FileName) 

JPEG

JPEG文件導(dǎo)出現(xiàn)在具有SaveToFile和SaveToStream的速度和質(zhì)量參數(shù)，例

[C#]

case 2: 
Steema.TeeChart.Export.JPEGFormat jPEG = tChart1.Export.Image.JPEG; 
     jPEG.GrayScale = true; 
     jPEG.Height = 500; 
     jPEG.Width = 700; 
     jPEG.Quality = 100; 
     jPEG.Save(saveFileDialog1.FileName); 
     break; 

[VB.Net]

Case 2 
Dim JPEGf As Steema.TeeChart.Export.JPEGFormat = TChart1.Export.Image.JPEG 
     JPEGf.Height = 500 
     JPEGf.Width = 700 
     JPEGf.GrayScale = True 
     JPEGf.Quality = 100 
     JPEGf.Save(SaveFileDialog1.FileName) 

質(zhì)量值（從1到100）將使文件更大，從而更慢地通過網(wǎng)絡(luò)傳輸 - 但質(zhì)量更好！您需要根據(jù)自己的應(yīng)用決定最佳平衡。通過將“Enhanced”設(shè)置為True，可以簡單地創(chuàng)建

WMF和EMF

增強(qiáng)型圖元文件，例

[C＃]

case 3: 
     Steema.TeeChart.Export.MetafileFormat metaFile = tChart1.Export.Image.Metafile; 
     metaFile.Height = 500; 
     metaFile.Width = 700; 
     metaFile.Enhanced = false; 
     metaFile.Save(saveFileDialog1.FileName); 
     break; 

[VB.Net]

Case 3 
     Dim MetaFile As Steema.TeeChart.Export.MetafileFormat = TChart1.Export.Image.Metafile 
     MetaFile.Height = 500 
     MetaFile.Width = 700 
     MetaFile.Enhanced = False 
     MetaFile.Save(SaveFileDialog1.FileName)

由于Microsoft的.Net Framework類庫，特別是 System.Drawing.Imaging命名空間中包含的類， GIF TeeChart for .Net能夠支持以GIF格式導(dǎo)出位圖，例

[C＃]

case 5: 
     Steema.TeeChart.Export.GIFFormat gIF = tChart1.Export.Image.GIF; 
     gIF.Height = 500; 
     gIF.Width = 700; 
     gIF.ColorReduction = Steema.TeeChart.Export.GIFFormat.GIFColorReduction.GrayScale; 
     gIF.Save(saveFileDialog1.FileName); 
     break; 

[VB.Net]

Case 5 
     Dim GIF As Steema.TeeChart.Export.GIFFormat = TChart1.Export.Image.GIF 
     GIF.Height = 500 
     GIF.Width = 700 
     GIF.ColorReduction = Steema.TeeChart.Export.GIFFormat.GIFColorReduction.GrayScale 
     GIF.Save(SaveFileDialog1.FileName) 

PNG

PNG格式保留了GIF格式的許多優(yōu)點(diǎn)，但也提供了超出GIF格式的功能。PNG改進(jìn)了GIF逐步顯示圖像的能力; 也就是說，當(dāng)圖像通過網(wǎng)絡(luò)連接到達(dá)時(shí)，顯示更好和更好的圖像近似值，例：

[C＃]

case 6: 
     Steema.TeeChart.Export.PNGFormat pNG = tChart1.Export.Image.PNG; 
     pNG.Compression = 100; 
     pNG.GrayScale = true; 
     pNG.Height = 500; 
     pNG.Width = 700; 
     pNG.Save(saveFileDialog1.FileName); 
     break; 

[VB.Net]

Case 6 
     Dim PNGf As Steema.TeeChart.Export.PNGFormat = TChart1.Export.Image.PNG 
     PNGf.Compression = 100 
     PNGf.GrayScale = True 
     PNGf.Height = 500 
     PNGf.Width = 700 
     PNGf.Save(SaveFileDialog1.FileName) 

TIFF

TIFF是一種靈活且可擴(kuò)展的格式，受到各種平臺(tái)和圖像處理應(yīng)用程序的支持。 例

[C#]

case 7: 
     Steema.TeeChart.Export.TIFFFormat tIFF = tChart1.Export.Image.TIFF; 
     tIFF.Compression = Steema.TeeChart.Export.TIFFFormat.TIFFCompression.LZW; 
     tIFF.Height = 500; 
     tIFF.Width = 700; 
     tIFF.Save(saveFileDialog1.FileName); 
     break; 

[VB.Net]

Case 7 
     Dim TIFF As Steema.TeeChart.Export.TIFFFormat = TChart1.Export.Image.TIFF 
     TIFF.Compression = Steema.TeeChart.Export.TIFFFormat.TIFFCompression.LZW 
     TIFF.Height = 500 
     TIFF.Width = 700 
     TIFF.Save(SaveFileDialog1.FileName) 

Adobe Flex/Flash/SWF

TeeChart現(xiàn)在可以導(dǎo)出到Adobe Flex腳本文件（* .mxml），然后可以通過Flex的免費(fèi)編譯器（mxmlc.exe）進(jìn)行編譯，以創(chuàng)建* .swf（Flash）文件。有關(guān)如何在運(yùn)行時(shí)實(shí)現(xiàn)此功能的詳細(xì)示例，包括如何向?qū)С龅膱D表添加動(dòng)畫的詳細(xì)信息。
