C# Cropped Picture SpreadsheetGear API Sample

// Create a new workbook and get a reference to the active worksheet
SpreadsheetGear.IWorkbook workbook = SpreadsheetGear.Factory.GetWorkbook();
SpreadsheetGear.IWorksheet worksheet = workbook.ActiveWorksheet;

// This picture consists of the SpreadsheetGear logo and the text "SpreadsheetGear" to 
// the right of the logo.
byte[] imageBytes = System.IO.File.ReadAllBytes(@"Files\SG-Logo-Text.png");

// Add the picture to the worksheet, specifying the size (in this case 7" x 1" which is
// the original dimensions of the picture).  Note all units are measured in Points, where
// 1 inch == 72 Points.
var shape = worksheet.Shapes.AddPicture(imageBytes, 10, 10, 7 * 72, 1* 72);

// Get the IPictureFormat object from the IShape, which has various picture-related APIs, 
// including cropping APIs.
SpreadsheetGear.Shapes.IPictureFormat picture = shape.PictureFormat;

// We pre-measured the width of just the logo which has a width of 1.35 inches starting 
// from the left edge.  The full picture is 7 inches long, so we should crop from the 
// right edge of the picture a distance of 7" - 1.35".  Again, this API is measured in 
// Points, so we also multiply by 72.
picture.CropRight = (7.0 - 1.35) * 72;

// Additional Notes on Cropping:
//   - IPictureFormat also has the properties CropLeft, CropTop and CropBottom.
//   - Specify crop measurements based on the dimensions of the *original picture size*
//     and not the dimensions that you specified for the shape (IShape.Width / Height).
//   - Negative crop values can be used to extend the shape's boundary beyond the picture.

// Add a second uncropped copy of this picture below the cropped
// picture for comparison purposes.
worksheet.Shapes.AddPicture(imageBytes, 10, 100, 7 * 72, 1* 72);
