JPGDecodePNO HB++ Package
Sample App & Image
Sample App & Image

Version 1.0 Released March 18, 2004!

JPGDecodePNO is an HB++ Package that enables you to very quickly decode and view JPG images in your HB++ application, on ARM powered PalmOS devices. JPGDecodePNO currently decodes images on Palm devices with ARM processors (all devices running PalmOS5 and higher) only, and does not decode an image on devices with Motorola 68K processors (all PalmOS 4.x and older devices). It employs a PACE Native Object (PNO, formerly called Armlet) function for extremely fast decoding.

JPG images files stored as binary resources, or as JPG streamed files in the Palm's main memory (RAM), and standard JPG files on VFS expansion cards are supported. They are passed to the decoding function as a standard stream object.

JPG images are decoded to the dimensions and density (standard or high density) that you specify. Images are decoded and copied into a bitmap object that you define in your application. Once the image has been decoded into the bitmap, you can display and maniuplate that bitmap using the standard HB++ methods.

A modified version of the JPEGViewer sample application is provided, demonstrating how to use the JPGDecodePNO package in an image browser. It also demonstrates how you can decode the image to an output bitmap larger than the display, and scroll around the image using pen control.
