Sample Application

SFJPGView is a custom SFX control that provides JPG image display capabilities for your SatForms applications. Because it is a custom control, it integrates directly into your forms like other native controls. Numerous script methods are also provided to give you complete runtime control over the control, including size, position, visibility, the image being displayed, visibility, and more. The SFJPGView control also provides optional OnClick scripting support.

JPG images may be stored in the Palm's internal memory or on VFS expansion cards (SD, MMC, or MemoryStick cards).

SFJPGView supports SatForms 3.0 and higher, and PalmOS 3.5 and higher. On OS 3.5 and 4.x devices, 68K assembler code is used to optimize the JPG decoding speed. On OS5 ARM-based devices, a PNO (Pace Native Object, formerly called ARMlets) is used for nearly instantaneous JPG decoding and display. For devices that support high density displays (most OS5 devices and the Tungsten|W), the image is drawn in high density mode.
