Java-based SpriteViewer/SpriteConverter prerelease

Hi,

I have just put the latest version (0.2.0) of SpriteViewer/SpriteConverter online, a Java-based tool (so running on all platforms where Java SE version 7 or later is available – Windows, MacOS, Linux including Raspian) to view the content of Sprites files and convert sprite(s) within to common bitmap formats like PNG, BMP, JPEG and GIF.

Both a simple GUI (SpriteViewer) and a command line tool (SpriteConverter) is included.

The new version fixes all known bugs and adds a palette view, support for classic 16/64 entry palette 256 colour sprites, D&D of Sprites file, export of a sprite from the GUI as PNG/JPEG/BMP/GIF, avoiding alpha channel when converting to formats without alpha support (JPEG, BMP) and a slightly more verbose ReadMe.

Hopefully, all known Sprite formats are now supported. There is something slightly wrong with the calculation of the colours in 16/64 entry palettes when extending to 256 colours, but this should be hardly noticeable.

Thanks to Anton Reiser, Jan de Boer, Jeffrey Lee and Martin Würthner for their input. Much appreciated.

Cool, is working fine.
Have try with WIN10 and with Titanium Linux…

I have released 0.3.0 of SpriteViewer/SpriteConverter which fixes the serious converter bug I discovered…

I tested this quickly, and it coped with every sprite file I have thrown at it. Great stuff, Steffen! It is really nice that I can look at sprite files in the RISC OS partition on my Windows machine without having to boot into VirtualRPC first.

The obvious next step is to implement a Draw viewer. And then of course an ArtWorks viewer. That will keep you busy for a while… ;-)

I am trying to tackle the easy stuff first…nearly-ready is the BBC BASIC viewer (just detokenizing, no syntax colouring yet!), the Text viewer with proper Acorn Latin 1 encoding support and – most important for me when working in my Emulator/Network share mixed OS world – the Archive viewer, which will handle ZIP as well as – thanks to the work done by James Woodcock – Spark/ArcFS, PackDir, Squash and CFS.

Once everything fits together, it will be a true “RISC OS file browser” with a plugin service concept, so anyone competent can contribute viewers for specific filetypes. So that will be the moment when I expect you to contribute that ArtWorks viewer :-)
