Adding images into Excel using EPPlus
I am trying to add the same image multiple times into an excel file using EPPlus. I am using the following code to do so:
Image logo = Image.FromFile(path);
ExcelPackage package = new ExcelPackage(info);
var ws = package.Workbook.Worksheets.Add("Test Page");
for(int a = 0; a < 5; a++)
{
ws.Row(a*5).Height = 39.00D;
var picture = ws.Drawings.AddPicture(a.ToString(), logo);
picture.SetPosition(a*5, 0, 2, 0);
}
Everything works perfectly and all the images are correctly added but they are stretched downwards. Here is what one of the pictures should look like:
But it looks like this in excel:
I have to resize each row of the start of each picture but I dont think that would be affecting it. Would there be a way to add the pictures/do what I am trying to do or would I have to copy-paste the images in manually? (I am using the picture as an example)
Thanks.
I'm not sure if this is the best solution but definetly a workaround for your problem.
Here's what I did:
ExcelPackage package = new ExcelPackage();
var ws = package.Workbook.Worksheets.Add("Test Page");
for (int a = 0; a < 5; a++)
{
ws.Row(a * 5).Height = 39.00D;
}
for (int a = 0; a < 5; a++)
{
var picture = ws.Drawings.AddPicture(a.ToString(), logo);
picture.SetPosition(a * 5, 0, 2, 0);
}
Here is how it looks.
For some reason when we have the row height set, its interfering with the picture height.
这是您可以在C#中应用的一种解决方案。
private void AddImage(ExcelWorksheet oSheet, int rowIndex, int colIndex, string imagePath)
{
Bitmap image = new Bitmap(imagePath);
ExcelPicture excelImage = null;
if (image != null)
{
excelImage = oSheet.Drawings.AddPicture("Debopam Pal", image);
excelImage.From.Column = colIndex;
excelImage.From.Row = rowIndex;
excelImage.SetSize(100, 100);
// 2x2 px space for better alignment
excelImage.From.ColumnOff = Pixel2MTU(2);
excelImage.From.RowOff = Pixel2MTU(2);
}
}
public int Pixel2MTU(int pixels)
{
int mtus = pixels * 9525;
return mtus;
}
try this
Image logo = Image.FromFile(path);
ExcelPackage package = new ExcelPackage(info);
var ws = package.Workbook.Worksheets.Add("Test Page");
for(int a = 0; a < 5; a++)
{
ws.Row(a*5).Height = 39.00D;
var picture = ws.Drawings.AddPicture(a.ToString(), logo);
// xlMove disables the auto resizing
picture.Placement = xlMove; //XLPlacement : xlMoveAndSize,xlMove,xlFreeFloating
picture.SetPosition(a*5, 0, 2, 0);
}
or
Image logo = Image.FromFile(path);
ExcelPackage package = new ExcelPackage(info);
var ws = package.Workbook.Worksheets.Add("Test Page");
for(int a = 0; a < 5; a++)
{
ws.Row(a*5).Height = 39.00D;
var picture = ws.Drawings.AddPicture(a.ToString(), logo);
picture.From.Column = 0;
picture.From.Row = a;
picture.SetSize(120, 150);
}
