Creates new BmpImage instance from content, represented as byte stream, and with specified name
name - Name of the BMP image. Cannot be null, empty or whitespaces.binaryContent - Content as byte stream. Reading begins from original
position. Cannot be null. Should be readable and seekable. If this
instance will be disposed, this stream will be disposed too.IllegalArgumentExceptionInvalidImageFormatExceptionpublic BmpImage(String name, String contentInBase64)
Creates new BmpImage instance from content, represented as base64-encoded string, and with specified name
name - Name of the BMP image. Cannot be null, empty or whitespaces.contentInBase64 - Content as base64-encoded string. Cannot be null,
empty or whitespaces. If it is not a BMP content, exception will be
thrown.IllegalArgumentExceptionInvalidImageFormatExceptionpublic ImageType getType()
Returns ImageType.Bmp

Checks whether specified stream is a valid BMP image
binaryContent - Byte stream, that presumably contains a BMP imagepublic static boolean isValid(String contentInBase64)
Checks whether specified base64-encoded string is a valid BMP image
contentInBase64 - Content of the presumably BMP image in a form of

Creates and returns a new reduced BMP image, but with specified new reduced height and proportionally reduced width.
reduceToNewHeight in class RasterImageResourceBasetargetHeightInPixels - Height of the desired BMP image in pixels.
Should be strictly lesser than original height.
