Example
WINDEVJavaUser code (UMC)
ImageInfo, Format are strings
Height, Width are int
// Retrieve the characteristics of the image
ImageInfo = BitmapInfo("C:\Windows\TILES.BMP")
Format = ExtractString(ImageInfo, 1)
Width = Val(ExtractString(ImageInfo, 2))
Height = Val(ExtractString(ImageInfo, 3))
// Display the characteristics
Info("Format of the image: " + Format, "Width: " + Width, "Height: " + Height)
Syntax
<Result> = BitmapInfo(<Name of Image File>)
<Result>: Character string
  • Characteristics of the image in the following format:
    <Format> + TAB + <Width> + TAB + <Height> + TAB + <Bits/pixel>

    <Format>Character string
    • Three characters are used to identify the image format: "BMP", "GIF", "PDF", ...
    • "BAD" if the image nameis an non-existing file or if the format is unknown
    <Width>IntegerWidth of image in pixels.
    <Height>IntegerHeight of image in pixels.
    <Bits/pixel>Character stringNumber of bits per pixel:
    • 1 (monochrome image)
    • 4 (16-color palette)
    • 8 (256-color palette)
    • 24 (no palette, 16 millions of colors)
    • 32 (no palette, true color)
    Java The number of bits per pixel is always equal to 0.
  • If an error occurs, the following string is returned:
    "BAD" + TAB + TAB + TAB
<Name of Image File>: Character string (with quotes)
  • Name of image or name of PDF file, including its full or relative path (up to 260 characters). A UNC path can be used.
  • Name of control linked to an image memo item.
Java The PDF files are not supported.
Remarks

Various

  • BitmapInfo can be used with the files in PDF format.
    Caution: the GDI + framework must be installed on the computer.
    Java This feature is not available.
  • For the images in WMF or EMF format, <Bits/pixel> is equal to 0.
  • The following formats of image files are supported:
Component : wd240obj.dll
