Description

here is my code:
f.AddPictureFromBytes(sheetName, fmt.Sprintf("A%d", index), fmt.Sprintf(``{"print_obj": true, "lock_aspect_ratio": false, "locked": false, "positioning" : "oneCell", "x_scale": %2f, "y_scale": %2f, "x_offset":1, "y_offset":1}``, xScale, yScale), "image", ".jpg", bytes)
