本教程概述了以各种格式导出TeeCharts并导入TeeChart自己的.ten格式图表模板。
可用导出格式。可以将所有格式复制到文件或剪贴板或Stream。
ten格式是一种灵活的格式,可存储图表属性信息和(可选)图表数据。文件很小(取决于数据),非常适合网络用于更新基于实时客户端的图表。
导出到文件是合理的,在大多数情况下,您只需要定义目标文件名。
[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 TChart1.Export.Image.Metafile.Save(SaveFileDialog1.FileName) Case 5 TChart1.Export.Image.GIF.Save(SaveFileDialog1.FileName) Case 6 TChart1.Export.Image.PNG.Save(SaveFileDialog1.FileName) Case 7 TChart1.Export.Image.TIFF.Save(SaveFileDialog1.FileName) End Select End If End Sub
BMP文件导出具有颜色和大小的附加参数,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文件导出现在具有SaveToFile和SaveToStream的速度和质量参数,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)
质量值(从1到100)将使文件更大,从而更慢地通过网络传输 - 但质量更好!您需要根据自己的应用决定最佳平衡。通过将“Enhanced”设置为True,可以简单地创建
增强型图元文件,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类库,特别是 System.Drawing.Imaging命名空间中包含的类, GIF TeeChart for .Net能够支持以GIF格式导出位图,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格式保留了GIF格式的许多优点,但也提供了超出GIF格式的功能。PNG改进了GIF逐步显示图像的能力; 也就是说,当图像通过网络连接到达时,显示更好和更好的图像近似值,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是一种灵活且可扩展的格式,受到各种平台和图像处理应用程序的支持。 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)
TeeChart现在可以导出到Adobe Flex脚本文件(* .mxml),然后可以通过Flex的免费编译器(mxmlc.exe)进行编译,以创建* .swf(Flash)文件。有关如何在运行时实现此功能的详细示例,包括如何向导出的图表添加动画的详细信息。
