I want to fill the background of excel cells with colours made up from the known red, green and blue components of the colours. To do this I found I needed to use:
$sheet->Range($rng)->Interior -> {PatternColor} = rgb colour value
$sheet->Range($rng)->Interior -> {Pattern} = pattern value
This site https://docs.microsoft.com/en-us/office/vba/api/Excel.XlPattern gives ‘values’ for 20 patterns including xlPatternSolid which I thought would give me the whole cell filled with that colour. This was not the case as the Perl below shows.
This code gives an Excel spreadsheet where:
Column C is the key to a hash which holds the pattern ‘names’ such as xlPatternSolid
Column D gives the cell filled with the colour and effect of the pattern
Column E gives the value of the pattern ‘names’ as shown on the web-site.
Cell D20 is where the xlPatternSolid has been used. This has no colour instead of the solid colour I was hoping for. Also cell D3 has no colour – the name of this colour pattern xlPatternAutomatic – I was not sure what to expect for this.
I did notice that the sides of cells D20 and D3 are no longer there.
How can I get cells filled with the solid colour?
