Convert PS to TGA via Java
Export PS file to TGA within any within any Java J2SE, J2EE, J2ME applications without using Adobe® Acrobat Reader
Converting a PostScript (PS) file to a Tagged Image File Format (TGA) image in Java can be done in two easy steps. The first step is to use the Aspose.PDF for Java API to export the PS file to a JPEG image. This API is part of the Aspose.Total for Java package, which provides a comprehensive set of APIs for manipulating documents, images, and other file formats.
Once the PS file has been converted to a JPEG image, the second step is to use the Aspose.Imaging for Java API to render the JPEG image to a TGA image. This API is also part of the Aspose.Total for Java package and provides a powerful set of tools for manipulating images. It can be used to perform a wide range of image processing tasks, such as resizing, cropping, rotating, and converting images from one format to another.
By using the Aspose.PDF for Java and Aspose.Imaging for Java APIs, you can easily convert a PS file to a TGA image in Java. Both APIs are part of the Aspose.Total for Java package, which provides a comprehensive set of APIs for manipulating documents, images, and other file formats. With just two simple steps, you can quickly and easily convert a PS file to a TGA image in Java.
Convert PS to TGA in a Single File via Java
The API also allows you to export PS file to TGA to a single file. In order to convert all pages, you can first render your PS document to one TIFF file and after that, you can export the TIFF file to TGA. You can open the input file using Document class and create Resolution, TiffSettings, & TIFF device objects. You can get a single TIFF image using process method of TiffDevice class. Finally, you can load TIFF file using Image class and save it to TGA format using save method.
Convert PS to TGA With Watermark via Java
Using the API, you can also export PS file to TGA with watermark in your TGA document. In order to add a watermark to you can first convert PS to JPEG and add a watermark in it. In order to add watermark, load an image file using the Image class, create an object of the Graphics class and initialize it with Image object, create a new Matrix object and set translation and transformation to the desired angle and add watermark using Graphics.drawString method. After adding the watermark in your image, you can save the JPEG as TGA format.
Convert & Rotate PS to TGA File via Java
Using the API, you can also rotate the output TGA image as per your needs. The Image.rotateFlip method can be used to rotate the image by 90/180/270-degrees and flip the image horizontally or vertically. The library provides simple methods to perform complex operations while encapsulating all ugly details. You can specify the type of rotation and flip to apply to the image. In order to rotate and flip the image, you can load the converted JPEG image using the Image class and call the Image.rotateFlip method while specifying the appropriate RotateFlipType .

What is PS File Format?
The PS (PostScript) file format is a page description language developed by Adobe Systems. It is commonly used for printing and is supported by a wide range of printers and imaging devices. PS files contain instructions that describe how elements such as text, images, and graphics should be rendered on a printed page.
PS files are created by applications that generate PostScript output, such as Adobe Illustrator, Adobe InDesign, or other graphics software. They are primarily used in professional printing workflows, where high-quality and consistent output is required.
The PS file format is based on a stack-based programming language, where commands and operands are placed on a stack and executed in a sequential manner. This allows for precise control over page layout, typography, color, and other printing parameters.
PS files are typically text-based and can be opened and edited with a text editor. They consist of a series of ASCII characters that represent the PostScript code. The code describes the arrangement and appearance of objects on a page, including text positioning, image placement, and graphical transformations.
While PS files are primarily used for printing, they can also be converted to other formats for digital distribution or further processing. For example, PS files can be converted to PDF (Portable Document Format) files, which are widely supported and can be easily viewed and printed on various devices.
What is TGA File Format?
The Truevision Graphics Adapter (TGA) is a raster graphics file format developed by Truevision Inc. It was initially designed as the native format for TARGA and VISTA boards, which were among the first graphics cards for IBM PC compatibles to offer true color display with 24 bits. TGA supports up to 32 bits per pixel and includes features such as compression, alpha channels, and gamma correction.
The TGA file format is relatively straightforward and consists of several mandatory fields followed by a variable-length image data section. The header of a TGA file must include specific fields such as the number of image ID bytes, the number of color map entries (if applicable), the number of image pixels per byte, the X and Y coordinates of the image origin, the width and height of the image in pixels, the number of bits per pixel, and the image descriptor byte.
The image data section of the TGA file contains the actual image pixels stored as a sequence of bytes. Each pixel is represented by a specified number of bits, which must be a multiple of 8 as per the header. The image descriptor byte provides information about the image orientation and alpha channel. The highest two bits indicate the alpha channel depth, while the remaining six bits determine the image orientation: left-to-right, top-to-bottom; right-to-left, top-to-bottom; left-to-right, bottom-to-top; or right-to-left, bottom-to-top.
If the image includes an alpha channel for transparency, it will be stored in a separate section after the image data. The alpha channel data consists of a sequence of bytes, with each byte representing the opacity of a corresponding pixel.
