How to fit diagram in a page with viewbale/readable content

Aspose.Diagram Product Family
1

In the attached file which we are printing in tiff, we want to fit the diagram in a page with viewbale/readable content.
We have tried many drawing and printing properties but, none of them seem to be working as per expected.

Sample code for propetirs that we used is as per following,

//Formating
foreach (AsposeVisio.Page page in visioDocument.Pages)
{
page.PageSheet.PageProps.PageHeight.Value = 11.0;
page.PageSheet.PageProps.PageWidth.Value = 8.5;

page.PageSheet.PrintProps.CenterX.Value = AsposeVisio.BOOL.True;
page.PageSheet.PrintProps.CenterY.Value = AsposeVisio.BOOL.True;
page.PageSheet.PrintProps.OnPage.Value = AsposeVisio.BOOL.True;

page.PageSheet.PageProps.DrawingSizeType.Value = AsposeVisio.DrawingSizeTypeValue.FitPageDrawContents;

}

//Printing
AsposeVisio.Saving.ImageSaveOptions options = new AsposeVisio.Saving.ImageSaveOptions(AsposeVisio.SaveFileFormat.Tiff);
options.Resolution = 300;

options.ExportHiddenPage = true;

AsposeVisio.Saving.PageSize pageSize = new AsposeVisio.Saving.PageSize(GetPaperSize(printConfiguration.VisioPrintingSetting.PageSize));

pageSize.Height = (float)(11 * 300);
pageSize.Width = (float)(8.5 * 300);

options.PageSize = pageSize;
options.EnlargePage = false;

options.TiffCompression = AsposeVisio.Saving.TiffCompression.Ccitt4;
options.ImageColorMode = AsposeVisio.Saving.ImageColorMode.Grayscale;

                options.PageCount = 1;
                for (int i = 0; i < _document.Pages.Count; i++)
                {
                    options.PageIndex = i;
                    _document.Save(@"D:\DVisio{i}.tif", options);
                }

Kindly look into it, and suggest us if any changes require from our side.

Note: We are using print paper as Letter (8.5 * 11)

Please set the unit of pageszie to pt,as this sample code:

        float width = (float)diagram.Pages[0].PageSheet.PageProps.PageWidth.Value * 72f;
        float heitht = (float)diagram.Pages[0].PageSheet.PageProps.PageHeight.Value * 72f;
        options.PageSize = new PageSize(width, heitht);
        diagram.Save("out.tiff", options);

Thanks.

Hello @philip.zhou,

Thank you for quick response!

We’ve tried above solution and we have still found issue in content reading(not readable) and dimensions are not matched with our standards for letter paper.

Is there any recommendations/solutions for above stated issue?

Thank You.

We found that the tiff file generated by the following code is different from yours, please share your executable code to generate tiff .

        Diagram diagram = new Diagram("Visio.vsd");
        Aspose.Diagram.Saving.ImageSaveOptions options = new Aspose.Diagram.Saving.ImageSaveOptions(SaveFileFormat.TIFF);
        float width = (float)diagram.Pages[0].PageSheet.PageProps.PageWidth.Value * 72f;
        float heitht = (float)diagram.Pages[0].PageSheet.PageProps.PageHeight.Value * 72f;
        options.PageSize = new PageSize(width, heitht);
        diagram.Save("out.tiff", options);

Hello @philip.zhou,

We need to print different scenarios PaperSizeFormat like letter, A4, etc. For the same file that’s why we set custom dimensions. In this situation, we are not able to use the below code.

float width = (float)diagram.Pages[0].PageSheet.PageProps.PageWidth.Value * 72f;
float height = (float)diagram.Pages[0].PageSheet.PageProps.PageHeight.Value * 72f;

Are there any recommendations/solutions for the above-stated issue?

Thank You.

@hemalp
Please set the pagesize to the size you want to print, in pt

//the above code
pageSize.Height = (float)(11 * 300); //unit to pt ,11inch*72
pageSize.Width = (float)(8.5 * 300);

Thanks

Hello @philip.zhou,

We set the below pagesize, but the output is incorrect
pageSize.Height = (float)(11 * 300);
pageSize.Width = (float)(8.5 * 300);
