Stored procedures
Saves a chart that was drawn beforehand in WMF format.
Example
// Saves the chart named "MyChart" in the "C:\Charts\Chart.WMF" file
grSaveWMF("MyChart", "C:\Charts\Chart.WMF")
Syntax
<Result> = grSaveWMF(<Chart Name> , <Name of WMF File>)
<Result>: Boolean
  • True if the chart was saved,
  • False otherwise.
<Chart Name>: Character string (with or without quotes)
Name of chart to use. This name corresponds to:
  • the chart name defined by programming with grCreate.
  • the name of Chart control found in the window editor, page editor or report editor.
<Name of WMF File>: Character string (with quotes)
Name and full path of the WMF file to create. The extension of the file is mandatory. This WMF file is created when grSaveWMF is called. The file is overwritten and re-created if it already existed.
Remarks

Saving a chart

  • To save a chart, the chart must have been drawn beforehand (grDraw). The modifications performed since the last call to grDraw will be ignored.
  • The default size of the image is set to 639 x 479. These dimensions are taken into account if the chart was never drawn or if it is not visible. If the chart was created by grCreate, the dimensions can be specified with grWndSize.

Backup in WMF format

  • This file can be read by a tool that recognizes WMF format.
  • The size of the file is identical to the size of the destination (size of window size, control or file).
  • We recommend that you preview the chart before it is saved in a file.

Differences between grDestinationWMF and grSaveWMF

  • grDestinationWMF is used to define the destination for the next drawing of the chart. When using grDraw, the chart will be drawn in the specified file and all the modifications performed since the last drawing of the chart will be taken into account.
  • grSaveWMF is used to save the chart in a file in WMF format. The image saved corresponds to the chart during the last call to grDraw. The modifications performed on the chart since the last call to grDraw will be ignored.
