Rich text: first word does not get the color specification #22

Closed mschnell1 closed 3 weeks ago

mschnell1 commented 3 weeks ago

In my tests I found that when I get a cell with rich text content (containing a string ABCDEFG) with e.g. one character underlined and all characters in the same color (e.g. blue) and decode the "words", the first word gets the color "Default".

When the words have different colors, also the first is correctly denoted,.

I think that when rich text in a cell is styled in the same way, it's probably styled content, not rich text.

I will test it later.

I tested it using <span style="color: #ffff00;"><b>AB<u>C</u>DEFG</b></span> and it printed out the following results:

// cell.format.unwrap().font.color
RGB(
    255,
    255,
    0,
)
// cell.rich_text.unwrap()
RichText {
    words: [
        Word {
            text: "AB",
            font: FormatFont {
                ...
                color: Default,
                ...
            },
        },
        Word {
            text: "C",
            font: Some(
                FormatFont {
                    bold: true,
                    italic: false,
                    underline: true,
                    size: 14.0,
                    color: RGB(
                        255,
                        255,
                        0,
                    ),
                    name: "Helvetica",
                },
            ),
        },
        Word {
            text: "DEFG",
            font: Some(
                FormatFont {
                    bold: true,
                    italic: false,
                    underline: false,
                    size: 14.0,
                    color: RGB(
                        255,
                        255,
                        0,
                    ),
                    name: "Helvetica",
                },
            ),
        },
    ],
}

This seems to be an Excel feature, and I think the FormatFont in Word needs to be adjusted to Optional to remove the ambiguity

mschnell1 commented 3 weeks ago

// cell.format.unwrap().font.color: Yep. I get exactly the same with pretty printing the rich text.

Hmm. .... From my "outside" perspective, the outcome seems to be hard to digest:

In the excel sheet the colors of the parts of the text are the same. The words of the rich text feature different colors, the first being "Default". Up to now the "Default" color seemed to mean a default for the complete table. Here the "Default" might mean the "overall" color of the Cell. But with the "text" being rich text, I up to now fail to find the "Cell Text Color" (which I successfully use with non-Rich-Text cells).

If there is a "Default cell text color" for rich text cells, it seems weird, that same is not used for the other words.

Got it working:

    for word in rt.words.iter() {
        let text_color = match word.font.color {
            FormatColor::Default => cell.text_color,
            text_color => text_color,
        };
       ...

Thanks for listening !

Seems to work OK this way
