Stored procedures
Retrieves the characteristics of an image file or the characteristics of a PDF file:
  • format,
  • width and height,
  • number of bits per pixel.
Java The PDF files are not supported.
Example
Reports and QueriesJavaUser code (UMC)PHPAjax
ImageInfo, Format are strings
Height, Width are int
// Retrieve the characteristics of the image
ImageInfo = BitmapInfo("C:\Windows\TILES.BMP")
// In Windows Mobile:
// ImageInfo = BitmapInfo("\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 file 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:
    • Reports and Queries All the formats described in fGraphicFilter.
    • Java JPEG, PNG, GIF or BMP.
    • PHP JPG, PNG, GIF, BMP. Depending on the version of the GD library, these formats may not be supported.
PHP

Pattern and PHP

In PHP, the drawing functions are based on the graphic library GD. This library is commonly used by the PHP hosting companies and therefore it is always enabled. The version of the GD library must be version 2.0.28 (or later). This library can be downloaded from the PHP site.
To enable (if necessary) this library locally, the following elements are required:
  • PHP installed.
  • the PHP.INI file found in the Windows directory must contain the following line: "extension=php_gd2.dll" (instead of ";extension=php_gd2.dll").
  • the php_gd2.dll file must exist in the directory of PHP extensions. This directory is defined in the PHP.INI file by the "extension_dir" variable.
Business / UI classification: Neutral code
