Can amiblitz (blitz basic2) blit an image per bitplane?

Michael Parent · 27 October 2009, 22:25

Hi everyone,

I was able to devise a nice trick using AMOSPRO that enabled even OCS Amigas to produce nice semitranslucent bob efects with no additional hit to the processor because Amos allows for you to blit an image and specifiy which of its bitpanes should be blitted and which should be ommitted.

Anyone know if such blitting is possible with Blitz2 ?

thanks,

Mike Parent

I'm sure there was something... bitplanesbitmap? It's been about 10 years since I used it though.

This may be a bit off-topic but in C or E or any other language that uses OS functions, you just set the PlanesPick field in the RastPort structure.

-edit-
Correction: There is no PlanesPick register in the RastPort structure but the BltBitMap has a mask parameter to let you select which bitplanes are affected by the blit.

-edit2-
BitPlanesBitMap documentation for Blitz2.

How to run TRP?..It only runs inside AMOS?
I´ve tried in cli but nothing happens

It only runs Amos and if you look at the Skate's last post in the thread you have to make a slight change to make the files load from somewhere that's not dependent on the Amos: assign on his hard drive.
