Digitally Sign BMP Documents in Java (Code Example)

Add Digital Signatures to BMP in Java

Add custom digital signatures to BMP documents in Java based on PFX certificate files. The all-in-one electronic signature API easily integrates with your Java application to give you a personalized document signing experience using a few lines of code.

Instantiate Signature with (BMP) as input document
Instantiate DigitalSignOptions object with certificate & password details
Call sign method of Signature class and pass DigitalSignOptions to it

Work with BMP Signature API

You require GroupDocs.Signature namespace to digitally sign documents in Java & J2SE applications. Use signature manipulation features to customize sign, search and signature verification processes, manage eSignature colors, styling and overall appearance.

Get the respective assembly files from downloads or fetch the whole package from Maven to add ‘Conholdate.Total` directly in your workspace.

Add Text Signatures to BMP in Java

Add customized text signature to a BMP document in Java using advanced text settings such as font color, size, name, text alignment and border adjustment.

Create a new instance of Signature class and pass input document
Instantiate the TextSignOptions object and specify text signature options
Call sign method of Signature class instance and pass TextSignOptions to it

eSign Remotely Located Documents

The document eSign API enables you to load & display remotely located documents from various cloud document storage sources such as stream, local disk, URL, FTP, Amazon S3, and Azure Blob storage. Using document information extraction feature - fetch the basic information about the source document file (BMP) along with extracting other valuable document information such as file type, file size, pages count, page height and width etc.

Add Image Signatures to BMP in Java

Using Conholdate.Total for Java - insert custom image as an electronic signature to a BMP document in Java. Add company logo, stamp icon or name using different colors and text effects.

Create a new instance of Signature class and pass input document to it
Instantiate the ImageSignOptions object and specify image signature options
Call sign method of Signature class instance and pass ImageSignOptions to it

Image Representation of Document Pages

Apply digital signatures to a wide range of document formats and generate the image representation of the already signed document pages in PNG, JPG or BMP formats. You can easily preview the complete document as a whole or choose to display some specific pages based on page numbers or page ranges.

Using advanced document previewing features - easily hide digital signatures from the signed documents while generating the document preview.

What is BMP file format?

BMP (or Bitmap) is a file format used to store digital images, especially on Microsoft Windows and OS/2 operating systems. It is used to store bitmap digital images, both monochrome (1 bit) and color (4, 8, 16, 24, and 32 bit). The BMP file format is widely used in the Windows world, where it is supported by virtually all the existing graphics applications. The BMP format is a device-independent bitmap graphics format that allows a flexible set of information to accompany the image data. A BMP file includes both encoded image data as well as information about the image, such as its size, resolution and color depth.

The BMP format supports various color depths. The BMP file compression method supports both lossless (uncompressed) and lossy (compressed) formats. Lossless compression saves space without sacrificing quality, while lossy compression sacrifices quality in order to save space.

BMP files are widely used in both professional and consumer applications. Web designers often use them for web page graphics to make their pages look better. They are also used for printing digital photos and for creating computer icons.
