- Saving a chart
- Backup in BMP format
- Differences between grDestinationBMP and <Chart>.SaveBMP
<Chart>.SaveBMP (Function) In french: <Graphe>.SauveBMP Saves a chart that was previously drawn in a file in BMP format.
// Saves the chart named CHART_MyChart in the "C:\Charts\Chart.BMP" file CHART_MyChart.SaveBMP("C:\Charts\Chart.BMP")
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 (in the window, page or report editor). <Name of BMP file>: Character string 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 <Chart>.Draw is used, the chart will be drawn in the specified file and all the changes made since the chart was last drawn 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 changes made to the chart since <Chart>.Draw was last called will be ignored.
