Title: raw files
Post by: Peter on April 10, 2018, 08:33:54 AM

Hello,

I was working on a project with raw files.
The idea was to hide graphics in easier manner.
The source code below is my result.

What do you think, it's usefull?

Code: [Select]

include "asm.inc"
window 640,512,1
SetFrames (60)

sys rawM[32],rawZ[32]

Sub StoreRaw(sys m,z)
for i=1 to 32
if rawM[i]=0
   rawM[i]=m
   rawZ[i]=z
   Return i
end if
next
End Sub       

Sub LoadRaw(string rawFile,sys size)
sys adr
hnd = OpenFile rawFile
adr = GetMemory(size*size*3)
ReadByte(hnd,*adr,size*size*3)
CloseFile(hnd)
Return StoreRaw(adr,size)
End Sub

Sub DrawRaw(sys id,x0,y0) as sys
for y=0 to <rawZ[id]
for x=0 to <rawZ[id]
    z=(y*rawZ[id]+x)*3
    p1=Peek rawM[id],z+0
    p2=Peek rawM[id],z+1
    p3=Peek rawM[id],z+2
    if p1>0 and p2>0 and p3>0
       Color p1,p2,p3     
       SetPixel x+x0,y+y0
    end if
next
next
End Sub

Sub ScaleRaw(sys id,single x0,y0, xz,yz) as sys
for y=0 to <rawZ[id]
for x=0 to <rawZ[id]
    z=(y*rawZ[id]+x)*3
    p1=Peek rawM[id],z+0
    p2=Peek rawM[id],z+1
    p3=Peek rawM[id],z+2
    if p1>0 and p2>0 and p3>0
       Color p1,p2,p3
       DrawPoint((x+x0)*xz,(y+y0)*yz,xz)
    end if
next
next
End Sub

Sub BlendRaw(sys id,x0,y0, float alpha) as sys
for y=0 to <rawZ[id]
for x=0 to <rawZ[id]
    z=(y*rawZ[id]+x)*3
    p1=Peek rawM[id],z+0
    p2=Peek rawM[id],z+1
    p3=Peek rawM[id],z+2
    if p1>0 and p2>0 and p3>0
       Color p1,p2,p3
       aPixel x+x0,y+y0,alpha
    end if
next
next
End Sub

Sub FreeRaw()
for i=1 to 32
if rawM[i]>0   
   FreeMemory rawM[i]
   rawM[i]=0
   rawZ[i]=0
end if
next
End Sub
 
float a 

tex1=LoadRaw ("raw/ball_64.raw",64)
tex2=LoadRaw ("raw/boll_64.raw",64)
tex5=LoadRaw ("raw/texture01_128.raw",128)

while Keydown(27)=0
cls 0,0,0
ScaleRaw tex5, 0, 0, 5,5
for i=0 to <640 step 64
    DrawRaw  tex1,i,100+sin(i+a)*60
    DrawRaw  tex2,i,200+sin(i+a)*60
next
Flip()
Wait(20)
a +=1
wend
FreeRaw()
WinEnd

hello Peter

i always see the command  WinEnd in your program
but when i search for it in the oxygen_help.chm file , i couldn't locate this o2 command?

is this your own command?

@ Peter
i checked your asm.inc  and found that  WinEnd

Code: [Select]

! WinEnd         Lib "asm.dll" () as sys 

so it means that this is your command?
