Hello,
Templates are not required for constructing a header. To create a header in a report programmatically, you can add a header object to the report's page layout. The following is an example for PDF reports. If you are creating a Word report instead, change the report type to 'docx' and create a DOCXPageHeader instead of a PDFPageHeader:
import mlreportgen.dom.*
import mlreportgen.report.*
rpt = Report('exampleReport', 'pdf') % Create an mlreportgen.report.Report object
% Create a sample image
im = Image(which('peppers.png'));
im.Width = '0.75in';
im.Height = '0.75in';
% Construct the header
header = PDFPageHeader();
append(header, im);
% Get the report's page layout and set header
layout = getReportLayout(rpt);
layout.PageHeaders = header;
% (optional) Adjust the space for the header and top page margin
layout.PageMargins.Header = '1in';
layout.PageMargins.Top = '0.5in';
% Add sample content
p = Paragraph('sample text');
add(rpt, p);
% Close and view report
close(rpt);
rptview(rpt)
If you would like to use a template, or if you are using a DOM API Document object instead of the newer Report API Report object, please see the following link:
