    As said above, if the area is not one colour the flood fill will not fill surrounding colours. It has no tolerance setting. Click on the ? below the flood fill to get exhaustive help on mouse-over of each tool. The flood-fill tooltip says:

    The flood-fill tool is used to fill areas with one color.
    Click with the left mouse to fill an area with the foreground color.
    Click with the right mouse to fill an area with the background color.

    Most JPG images will have slightly different colours within what looks like an area of uniform colour. Clicking a few times with the flood-fill tool will give a result like the attached image at best. At worst, you will get just small dots and blotches of colours. Zoom in with high magnification on an area of bright blue sky from a photograph, and you can see the different coloured pixels adjacent to each other.

    Pasha - If you click on the question mark icon on the Paint toolbar, you will get tooltips (written by Bhikkhu Pesala ) with information about the different tools.

    Flood fill must have perfectly uniform pixel color to work. Therefore it is not much good in a JPG. It is great for changing your mind about the color of a line or shape drawn with IP.

    You should play with good old MSPaint, Windows' hidden free treasure, to learn about simple paint tools. If you need more advanced selection ability, try some other freebies available on the Web:
    PaintStar - priceless, fast and light, with layers and everything
    The GIMP - the big guns, Photoshop without the big price tag

    It's: Shortened form of "It is"

    No tolerance indeed in the flood fill, so it searches for adjacent pixels with the same color from the click-position.
    I don't think a graphic format makes the difference, it's more the property of the image.
    If it's a photo, flood fill becomes difficult, but if it's a scan of a document, it may be another situation.
    So a workaround could be to first decrease the number of colors used as much as possible without distortion, and then try the flood fill.

    No, the format itself doesn't make the difference, but while a BMP, PNG or GIF may have areas of pure color, a JPG never will. Which is what I meant, but stated unclearly. Since most photos are JPG's - no flood.

    Default Change language in IrfanPaint?

    Hallo,

    Until now I don't find any possibility to change the language (from english to german) in IrfanPaint!

    Is it possible anyway?
    Otherwise I would recommend this wish as a suggestion for a next version!




    Gruß

    Actually it is not possible, but it's planned for the next version.

    The latest stable IrfanPaint version is the 0.4.13.70.
    IrfanPaint is now open-source (released under BSD license).

    Default IrfanPaint for Win98 ?

    MItaly,

    Why your plugin doesn't work in Win98SE, while its parent program IrfanView does? Can it earn finished Plugin Status under such scenario?

    Is it more advanced and feature & programming rich than GIMP 2.0 ? If compared to Win Paintbrush (more realistic), what exactly prevents it from working in Win98? Any compatibility fix timetable?

    Hmm, I consider it bad news if IrfanPaint wouldn't be compatible with W98.

    Maybe it has grown so in common use of the different formats, but technically, I don't agree.
    One can save a JPG with only 256 colors, and having a fullcolor photo as BMP.

    Floodfill could be sometimes not the only solution. A tool like the Color Replacer in PSP is another one.
