Samit,

1. LEADTOOLS provides support for loading document formats (such as XLS and PPT) as raster images (rasterization). Loading time depends on different factors, such as the original file size, the loading resolution and the loading bits per pixel. So if the document contains many objects, the rasterization process will take long time.

2. You can improve the quality of the images by increasing the loading resolution when loading documents. You can do this by using the following code:
+-------------+
Dim codes As New Leadtools.Codecs.RasterCodecs
codes.Options.RasterizeDocument.Load.XResolution = 300
codes.Options.RasterizeDocument.Load.YResolution = 300
Dim XLSImage As RasterImage = codes.Load("C:\Worksheet.xls")
+-------------+

Please note that increasing the resolution will also increase the required memory for the image and might affect the loading speed even more.

Thanks,
