Hi,

PFA the below Excels , While converting the below excels to Images "The header 1" does not appear in the image,While the source sheet has the Header 1.

Then the Charts borders in the images are not rendered well . The Top borders and left borders.

The Header and Border missing part has been highlighted in red in the Attached images.

Here is the code to convert to Images

Aspose.Cells.Workbook book = new Aspose.Cells.Workbook("C:\\A.xlsx");

Aspose.Cells.Worksheet sheet;

Aspose.Cells.Rendering.ImageOrPrintOptions imgOptions;

Aspose.Cells.Rendering.SheetRender sr;

Bitmap bitmap;

string number = "";

string[] name = new string[100];

imgOptions = new Aspose.Cells.Rendering.ImageOrPrintOptions();

for (int i = 0; i < book.Worksheets.Count; i++)

{

sheet = book.Worksheets[i];

imgOptions.HorizontalResolution = 118;

imgOptions.VerticalResolution = 112;

imgOptions.OnePagePerSheet = true;

imgOptions.IsImageFitToPage = true;

imgOptions.ImageFormat = System.Drawing.Imaging.ImageFormat.Tiff;

sr = new Aspose.Cells.Rendering.SheetRender(sheet, imgOptions);

if (i < 10)

{

number = "00" + i.ToString();

}

else if (i >= 10 && i < 100)

{

number = "0" + i;

}

else

{

number = i.ToString();

}

bitmap = sr.ToImage(0);

bitmap.Save("C:" + "\\sheetimage" + number + ".tiff");

}

And is there any Possibility to increase the quality of the rendered image ,though the Imageoptions.Quality attribute doesnt increase the quality of the image.

Appreciate your help in this regard.

Thanks,

Abdul R Sha

Hi,

Thanks for the sample files.

I can find the following issues:

1) Header 1 (text) from the A.xlsx file is not rendered in the image.

2) Charts with borders are not rendered fine (H.xlsx).

Regarding colors for headers, I could not find the issue, it works fine with latest version/fix v7.0.3.3.

I have logged a ticket with an id: CELLSNET-40150. We will look into soon.

Thank you.

Hi,

Thanks for the files.

I can find the issues using your new template file as mentioned in your attached docx file ("ExcelIssuesScreenshots.docx"-screen shots).

Sample code:

Aspose.Cells.Workbook book = new Aspose.Cells.Workbook("e:\\test2\\ExcelIssuesJan2.xlsx");

Aspose.Cells.Worksheet sheet;

Aspose.Cells.Rendering.ImageOrPrintOptions imgOptions;

Aspose.Cells.Rendering.SheetRender sr;

Bitmap bitmap;

string number = "";

string[] name = new string[100];

imgOptions = new Aspose.Cells.Rendering.ImageOrPrintOptions();

for (int i = 0; i < book.Worksheets.Count; i++)
{

sheet = book.Worksheets[i];

imgOptions.HorizontalResolution = 118;

imgOptions.VerticalResolution = 112;

imgOptions.OnePagePerSheet = true;

imgOptions.IsImageFitToPage = true;

imgOptions.ImageFormat = System.Drawing.Imaging.ImageFormat.Tiff;

sr = new Aspose.Cells.Rendering.SheetRender(sheet, imgOptions);

if (i < 10)
{

number = "00" + i.ToString();

}

else if (i >= 10 && i < 100)
{

number = "0" + i;

}

else
{

number = i.ToString();

}

bitmap = sr.ToImage(0);

bitmap.Save("e:" + "\\test2\\convv\\qsheetimage" + sheet.Index + number + ".tiff");

}

I have reopened your issue now, we will look into it soon.

Hi,

Our Project is going Live on 23rd jan.So i request you to Solve the issue before jan 16th. And We need a confirmation that this Chart to image rendering issues will not repeat again with the fix you provided with the templates that we shared. also we need some more clarifications on the topics listed below.
i) What is the root cause of the Chart issues which was not rendered properly in the images.
ii) Is the Chart to image issues feasible or not ?

So its always better to fix the issue before this date(Jan16th) so that we have some time to test and validate the results and appropriately come back to you if it has some more unexpected bugs after this Fix.Appreciate your help.

Thanks.
