libvita2d_sys is a fork from Xerpi's popular libvita2d, a 2D library (using the GPU) for PS Vita homebrew developers. Libvita2d is simple to use, and fast as it uses the GPU drawing primitives.

libvita2d_sys adds support for "system mode" applications, that is applications that can run in the background without closing ongoing games. One such example is ElevenMPV-A which allows you to play your own music while playing games.

Features

• "system mode" that actually works.
• Support for custom display resolutions, including 1280x720 and 1920x1080 (with Sharpscale or 1280x725 and 1920x1088 (without Sharpscale on PS TV).
• Hardware decoding for JPEG textures using Codec Engine.
• Supports loading textures using FIOS2 overlay (for example, directly from PSARC archives).
• Supports GXT textures.
• Extended PVF functionality.

Changelog

v1.46

• Remove SceLibc dependency.

v1.45

• Fixed a bug where input buffer size would not be checked in vita2d_load_PNG_buffer()
• Added support for CLUT, grayscale and ADAM7 PNG images.

v1.44

• Switch to VDSuite.
• Added ability to use vita2d_sys with externally initialized GXM context.
• Added ability to use shared driver memory for some of the GXM buffers.

v1.42

• Reimplemented screen cleaning to allow partial screen clean.
• Rendering resolution can now be changed at runtime.
• Added following functions:
  • vita2d_display_set_max_resolution()
  • vita2d_set_clear_vertices()
• Improved PVF font selection procedure for shared memory system fonts.

v1.41

• Use shared sync objects for shared fb.

v1.40

• Added out of memory protection for JPEG and PNG texture loaders.
• Fixed bug in hardware JPEG decoder that prevented CSC conversion for some images.
• Removed main memory support for hardware JPEG decoder, it's too slow.

v1.35

• Added documentation to vita2d_sys header.
• Removed some unnecessary checks in JPEG loaders.
• Added PNG loaders.
• Added vita2d_check_version()

v1.34

• Build with latest DolceSDK (stubs per library).
• Added GIM file loader:
  • vita2d_load_GIM_file()
  • vita2d_load_GIM_buffer()
• Reduced shader binaries size

v1.32

• Changed internal memory management. Simplified initialization procedure.
• Following functions are now deprecated:
  • vita2d_pass_mspace()
  • Call vita2d_set_heap_size() before initialization to change internal memory heap size from default (1MB).
• Improved PVF font rendering. Following functions are now deprecated:
  • vita2d_pvf_draw_text_ls()
  • vita2d_pvf_draw_textf_ls()
  • Use vita2d_pvf_linespace() instead.
• Added following functions:
  • vita2d_set_heap_size()
  • vita2d_load_custom_pvf_buffer()
  • vita2d_load_custom_pgf_buffer()
  • vita2d_pvf_linespace()
  • vita2d_pvf_charspace()
• Default PVF font is now opened on shared memory.

v1.22

• Do not set logging level internally.
• Added delay in shared fb opening loop.
