Parameters

flags

A combination of the RasterMemoryFlags enumeration members indicating the type of memory to allocate for the image data.

width

Width of the image in pixels.

height

Height of the image in pixels.

bitsPerPixel

The number of bits per pixel.

Valid values are 0, 1, 2, 3, 4, 5, 6, 7, 8, 12, 16, 24, 32, 48, and 64.

Use 0 to create an 8-bit grayscale image. In that case, the method ignores the order and the palette parameters.

order

Color order for 16-, 24-, 32-, 48- and 64-bit images.

If the resultant image is less than 16 bits per pixel, this will have no effect since palletized images have no order.

viewPerspective

Specifies where the beginning of the image is stored.

Most file formats start in the lower left corner while some formats start in the upper left corner.

palette

The palette that the image will use. You can specify your own palette, or use null (Nothing in Visual Basic) for LEAD's fixed palette. The palette member is used only when bitsPerPixel is less than or equal to 8.

Support for 12 and 16-bit grayscale images is only available in the Document/Medical Imaging editions.

There is some speed penalty (loss) for accessing RasterMemoryFlags.Tiled images. Therefore, it is not recommended for use with all images.

The RasterMemoryFlags.Tiled images are not used by default. LEADTOOLS will create them only if it failed to create RasterMemoryFlags.Conventional images and RasterMemoryFlags.NoTiled was not specified.

The following lists the distinct types of bitmaps:

• Conventional (uncompressed and contiguous) This is the most common type.
• Compressed (1-bit only)
• Tiled (uncompressed, stored internally as up to 64MB tiles)
