Please use following code:

Code: Select all

StiBmpExportSettings settings = new StiBmpExportSettings();
settings.ImageZoom = 2;

report.ExportDocument(StiExportFormat.ImageBmp, "1.bmp", settings);

If you want change image zoom in GUI you can use combo box "Zoom:".

For also you can change default value of combo box "Zoom:":

Code: Select all

StiSettings.Load();
StiSettings.Set("StiImageExportSetupForm", "Zoom", "200%");
StiSettings.Save();

Thank you.

Hi, Vital,

Thank you for your suggestion. But your example code does not solve my problem.

By default, the exported Jpeg image on my machine is 96dpi, but I would like to set the exported image resolution to 200dpi or 600dpi. The ImageZoom factor only resize the generated image, but not the resolution.

A related question: I can use StiPage.GetThumbnail() to get the same result as using ImageZoom, right?
