Hi!
I need to get the image from a specific sheet range (B2:D24, for example)
I have the code:
Code: Select all
Dim ofd As New OpenFileDialog
Dim workbook As New Workbook()
Dim sheet As Worksheet
Dim sImg As String = GetAppPath() & "\imgActual.jpg"
ofd.ShowDialog()
workbook.LoadFromFile(ofd.FileName)
sheet = workbook.Worksheets(0)
sheet.SaveToImage(sImg)
PB.Load(sImg)

But I don't get the image I need.

Is that possible?
Many Thanks!

Hello,

Thanks for your inquiry.
Our Spire.XLS does support the feature you need. If you were using the free version or old version, we suggest you first upgrade your dlls to the latest hotfix Spire.XLS Pack(Hotfix) Version:7.12.125 and use the "ToImage" method instead.

If you want to save the whole sheet to image, please use:
Code: Select all
Dim image As Image = sheet.ToImage(sheet.FirstRow, sheet.FirstColumn, sheet.LastRow, sheet.LastColumn)
image.Save(sImg )

You could also save a certain range to an image, eg, B2 to D24:
Code: Select all
Dim image As Image = sheet.ToImage(2,2,24,4)
image.Save(sImg )

If the the approaches I suggested do not make sense at your end, please send your sample document to us(support@e-iceblue.com) and then we will look into it.

Sincerely,
Jane
