This method loads image data from a file.
Parameters
None
Return Value
Returns True if successful. Returns False if unsuccessful.
Explanation
The LoadImageFromFile method loads image data from a file. The FileName property sets the file to be loaded. If successful, the image data is set in either the Image property or the Layer(LayerNumber).Imgae property as determined by the value set in the LayerNumber property. If the image is a multi-page image file, set the page to be loaded in the LoadPage property. Executing this method will set image information in the same properties as executing the GetImageFileType method.
The supported image formats are BMP, JPEG, TIFF (uncompressed, GROUP3-1D, GROUP4, PACKBITS, LZW, JPEG compression (partially not supported)), PNG, GIF, JPEG2000, FPX, WMF, EMF.
For 16 bit BMP and TIFF files:
16 bit BMP and TIFF files can be loaded but the loaded image data
will converted to 32 bit image data. Saving the data will result in
a 32 bit image.
For BMP compression, JPEG2000 and FPX formats:
Because standard .NET Framework does not support these image
formats, the ImageKit.NET3 Plugin (Win32 Dll files) are
required.
For WMF and EMF files:
WMF and EMF images are treated as raster images after loading.
Regarding FlashPix:
Flashpix image files are multi-resolution image files with a tiled
composition. Flashpix files store image data in a hierarchy from
the original image at the highest level. Each subsequent level
contains the same image with horizontal and vertical resolution
half that of the image in the level above. This allows editing and
printing at the optimum resolution. Each resolution image is
divided in to 64x64 tiles. Each tiled image can be uncompressed,
JPEG compression, or single color compression.
