    gdi question

    hi all.

    does anybody knows more about UI / "GDIp" properties, commands and syntax ? manual help doesn't show any help.

    for example: "Gdip_GetImagePixelFormat" ?

    "Gdip_LoadImageFromFile(a(b) )" does probably exists

    [code=thinbasic]hGpBitmap = Gdip_GetImagePixelFormat(JPGFileName, nFormat)

    ...
    Case %PixelFormat1bppIndexed : strFormat = "1 bpp indexed"
    Case %PixelFormat4bppIndexed : strFormat = "4 bpp indexed"
    Case %PixelFormat8bppIndexed : strFormat = "8 bpp indexed"
    Case %PixelFormat16bppGrayScale : strFormat = "16 bpp gray scale"
    Case %PixelFormat16bppRGB555 : strFormat = "16 bpp RGB 555"
    Case %PixelFormat16bppRGB565 : strFormat = "16 bpp RGB 565"
    Case %PixelFormat16bppARGB1555 : strFormat = "16 bpp ARGB 1555"
    Case %PixelFormat24bppRGB : strFormat = "24 bpp RGB"
    Case %PixelFormat32bppRGB : strFormat = "32 bpp RGB"
    Case %PixelFormat32bppARGB : strFormat = "32 bpp ARGB"
    Case %PixelFormat32bppPARGB : strFormat = "32 bpp PARGB"
    Case %PixelFormat48bppRGB : strFormat = "48 bpp RGB"
    Case %PixelFormat64bppARGB : strFormat = "64 bpp ARGB"
    Case %PixelFormat64bppPARGB : strFormat = "64 bpp PARGB"

    End Select
    [/code]

    try to build a new GDIp example for thinbasic.

    any help about GDIp features would be nice. best regards, frank
    you can't always get what you want, but if you try sometimes you might find, you get what you need

    Re: gdi question

    yes, that's ok with link and I know such stuff, but I would like to know what's already possible with current thinbasic beta issue and existing GDIp examples ?

    "Gdip_GetImagePixelFormat" is still missing so far as I can check it.
    also: "%PixelFormat1bppIndexed".

    perhaps it's possible to realize this feature for next thinbasic release ? would be very nice to see that!

    many thanks, good night, frank

    Re: gdi question

    thanks michael!

    ok, here my first attempt! but something important is still missing in code. to be truly, I am not very familiar with including freeImage.dll or gdiplus.dll for thinbasic. Need help, but it's exiting to see when script will work and run

    a) gdiplus.dll I have included
    b) example script for "Gdiplus Get_Export_list" properties is running fine ! (included in zip too)
    c) the example works with:
    "hStatus = GdipGetImagePixelFormat(JPGFileName, Counter)" so example counts Images and I noticed thinbasic knows "GdipGetImagePixelFormat" after including

    perhaps you or anybody else can check what's missing ? thanks in advance.

    last edit: update the code example with little success this version seems to run and show results with

    [code=thinbasic]"hGpBitmap = GdipGetImagePixelFormat(JPGFileName, pThumbnail)"[/code]

    seven messages will appear for testing: for example

    the pixelformat of the image is: 24552584 (24525184)
    perhaps anybody can check this code too if it's running on his machine.

    best regards, frank

    Re: gdi question

    Thanks Michale for the suggestion.
    Forum is becoming quite big so a little of "methodology" is necessary.
