Syntax
<Result> = <Chart control>.SaveBMP(<Name of BMP file>)
<Result>: Boolean
  • True if the chart was saved,
  • False otherwise.
<Chart control>: Control name
Name of the Chart control to use (found in the window editor, page editor or report editor).
<Name of BMP file>: Character string (with quotes)
Name and full path of BMP file to create. The file extension is mandatory. This BMP file is created during the call to <Chart>.SaveBMP. 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 (<Chart>.Draw). The modifications performed since the last call to <Chart>.Draw 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.

Backup in BMP format

  • This file can be read by a tool that recognizes the BMP 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 grDestinationBMP and <Chart>.SaveBMP

  • grDestinationBMP is used to define the destination for the next drawing of the chart. When using <Chart>.Draw, the chart will be drawn in the specified file and all the modifications performed since the last chart drawing will be taken into account.
  • <Chart>.SaveBMP is used to directly save the chart in a file in BMP format. The image saved corresponds to the chart during the last call to <Chart>.Draw. The modifications performed on the chart since the last call to <Chart>.Draw will be ignored.
