In an earlier post (pointing the finger at point) I showed that the Point() Command wasn't working properly either, as my then example showed:



This just copies what is drawn in the top left corner of the screen to somewhere below. It only displays the blue componant.

Looks like we have both found another patch 2 bug!

Yep, further examination shows, no red in 16bit displays and no red and green in 32 bit displays.

Has anyone tested this in 24bit?

some reason nVidia based cards don't like 24-bit colour

I use Patch 1 and have no problems with rgbr/g/b functions. I tested it with POINT and it works well, and I tested it with Memblocks, which is much faster, and it works (How faster could be LOCK PIXELS in comparsion to MEMBLOCK reading? I have no idea, because I only read from Memblocks).

Hi Viktor, could you post an example of your test using memblocks? I never worked with them.
Thanks

Okay, here is it:

Description: Bitmap size is 256x192 pixel (ZX Spectrum resolution), If I try to copy Bitmap 0 to other Bitmap, DB Pro crashed, so I load pictures offscreen in Bitmap 1.


make memblock from bitmap 1,1:bmd=bitmap depth(0):for y=0 to 191:for x=0 to 255:color=pointmem(x,y,1,bmd):r1(x,y)=rgbr(color):g1(x,y)=rgbg(color):b1(x,y)=rgbb(color):next x:next y:delete memblock 1:return

This is the procedure for converting memblock values to 16/24/32 bit screen depth color values:

function pointmem(xpos,ypos,mem,bmd)
if bmd=16 then value=memblock word(mem,12+(xpos*2)+(ypos*512)):cr=((value && 31)*8):cg=((value && 2016)/32)*3.98:cb=((value && 63488)/2048)*8:value=cr+cg*256+cb*65536
if bmd=24 then value=memblock word(mem,12+(xpos*3)+(ypos*768))+(memblock byte (mem,12+(xpos*3)+(ypos*768)+1)*65536)
if bmd=32 then value=memblock dword(mem,12+(xpos*4)+(ypos*1024))
endfunction value

This code was written by my boss, and it is pretty fast.

Yep! ZX Spectrum resolution, because we are working on the new generation of bmp2scr converter, that converts visual media to colorfull (or B/W) ZX Spectrum images/streams. If you got the XGamer (X-Box mag from Future Publishing) issue from June 2002, you can see on page 130 a example of the conversion. BTW: they used a earlier version which had not all graphic modes finished.

Nice to hear

Come to think of it where did you hear?

Serves me right. Feeling embarressed now, hehe.
