Param |
Description |
pstrFilename |
The full filename of the image to extract dimensions from. Starting from version 1.4 of II2LN you can also specify any |
iX |
The output parameter containing the Width (X) in pixels |
iY |
The output parameter containing the Height (Y) pixels |
iBitDepth |
The output parameter containing the bitdepth |
iDpiX |
The DPI of the image in X direction |
iDPI |
The DPI of the image in Y direction |
Returns:
-1 if the image format was not recognized. Otherwise 1.
Please note that the DPI variables may contain 0 if no DPI information was found in the image.
Usage:
Dim lRc As Long
Dim iX As Integer
Dim iY As Integer
Dim iBitDepth As Integer
Dim iDpiX As Integer
Dim iDpiY As Integer
lRc = GetImageDimension(strFileName, iX, iY, iBitDepth, iDpiX, iDpiY)
If lRc = 1 Then
Messagebox "The image dimensions are X=" & Cstr(iX) & " Y=" & Cstr(iY) & _
" BitDepth=" & Cstr(iBitDepth) & " DpiX=" & Cstr(iDpiX) & _
" DpiY=" & Cstr(iDpiY), 0, "Image Dimensions"
Else
Messagebox "Not a valid image file", 0, "Image Dimensions"
End If
