Transparent Background for Text

[Boop]

Being, bored + seeing how the NTSD skin(yes I follow the progress, because it is the only mod which is making progress) is getting ruined by non transparent text, I decided to make this .

Code:

.data
hDC dd ?

.code
draw_text proc
    
var_4           = dword ptr -4
lpString        = dword ptr  4
arg_4           = dword ptr  8
arg_8           = dword ptr  0Ch
arg_C           = dword ptr  10h

                push    esi
                mov     esi, [esp+4+lpString]
                mov     eax, [esi]
                mov     edx, [eax+44h]
                push    edi
                lea     ecx, [esp+8+lpString]
                push    ecx
                push    esi
                call    edx   ;Magic Call #1
                mov     edi, eax
                test    edi, edi
                jl      short loc_4012FC
                mov     eax, [esp+0Ch+arg_4]
                mov     ecx, [esp+0Ch]
                push    ebx
                push    TRANSPARENT             ; mode
                push    ecx             ; HDC
                mov        hDC, ecx
                call    ds:SetBkMode
                mov     edx, [esp+10h+arg_8]
                mov     eax, [esp+10h]
                push    edx             ; COLORREF
                push    eax             ; HDC
                call    ds:SetTextColor
                mov     ebx, [esp+10h+lpString]
                push    ebx             ; lpString
                call    ds:lstrlenA
                mov     ecx, [esp+24h]
                mov     edx, [esp+10h+arg_C]
                push    eax             ; int
                mov     eax, [esp+14h]
                push    ebx             ; LPCSTR
                push    ecx             ; int
                push    edx             ; int
                push    eax             ; HDC
                call    ds:TextOutA
                mov     edx, [esp+10h]
                mov     ecx, [esi]
                mov     eax, [ecx+68h]
      
                push    edx
                push    esi
                call    eax    ; Magic Call 2
                mov     eax, edi
                pop     ebx
                

loc_4012FC:                             ; CODE XREF: sub_401290+17j
                pop     edi
                pop     esi

    
    ret

draw_text endp

in rarara.asm, add(at the top bit, you should be able to figure it out) :

Code:

include \masm32\include\gdi32.inc
includelib \masm32\lib\gdi32.lib

Now there are two ways of using this. Patching every line of text that you want to be transparent (useful if you want the majority of your text to still have a background) or completely replacing the real function with your one.

#1:
;makes the background of the first line in the credits transparent
invoke CallPatch,004272C2h, addr draw_text

#2:
;i haven't tested this, should make all text transparent
invoke JmpPatch,00401290h, addr draw_text

Enjoy.

waitttttttttttttt.................
thats awesome
you found how to make text bmps (in the exe) in to pngs (trasparency)

if you can do this getting 2.0 to load pngs shouldn't be tough

[Boop]

No...


That is what I'm talking about(the blue background around the letters). Those little things really annoy me . Nothing to do with bmps, pngs, transparency or anything really.

[naruto hyuuga]

i noe
that blue background

its like when lf2 types the letters it's pasting the letters with a blue background together

so you can say they are bmps - a.bmp b.bmp c.bmp d.bmp e.bmp etc

so you like changed it to pngs - a.png b.png c.png d.png e.png etc

so its the same pic but with transparency
(atleast my logic)

i wonder if you can get 2.0 to load pngs (it will help ntsd2 (they needed alpha transparency before))

[TheNave]

naruto, you have absolutely no clue how that works and are talking random wrong sh*t... that stuff is all we need, thanks alot silva^^

[naruto hyuuga]

not working for me 0.o

i put the .code part in generic.inc's .code part
and .data part in generic.inc's .data part
and the

ASM-Code: .data hDC dd ?   .code draw_text proc   var_4 = dword ptr -4 lpString = dword ptr 4 arg_4 = dword ptr 8 arg_8 = dword ptr 0Ch arg_C = dword ptr 10h   push esi mov esi, [esp+4+lpString] mov eax, [esi] mov edx, [eax+44h] push edi lea ecx, [esp+8+lpString] push ecx push esi call edx ;Magic Call #1 mov edi, eax test edi, edi jl short loc_4012FC mov eax, [esp+0Ch+arg_4] mov ecx, [esp+0Ch] push ebx push TRANSPARENT ; mode push ecx ; HDC mov hDC, ecx call ds:SetBkMode mov edx, [esp+10h+arg_8] mov eax, [esp+10h] push edx ; COLORREF push eax ; HDC call ds:SetTextColor mov ebx, [esp+10h+lpString] push ebx ; lpString call ds:lstrlenA mov ecx, [esp+24h] mov edx, [esp+10h+arg_C] push eax ; int mov eax, [esp+14h] push ebx ; LPCSTR push ecx ; int push edx ; int push eax ; HDC call ds:TextOutA mov edx, [esp+10h] mov ecx, [esi] mov eax, [ecx+68h]   push edx push esi call eax ; Magic Call 2 mov eax, edi pop ebx     loc_4012FC: ; CODE XREF: sub_401290+17j pop edi pop esi     ret   draw_text endp

and this
include \masm32\include\gdi32.inc
includelib \masm32\lib\gdi32.lib
in rarara. asm top part (they were toghether)

and these

#1:
;makes the background of the first line in the credits transparent
invoke CallPatch,004272C2h, addr draw_text

#2:
;i haven't tested this, should make all text transparent
invoke JmpPatch,00401290h, addr draw_text

tried both not working

[Boop]

Works fine for: me, Nave, 1477. What doesn't work? You can't assemble the dll? If so what error do you get.

Doesn't work in game? Are you sure you are using the correct exe?

Kind of hard to help you, when all you say is "its not working"

[naruto hyuuga]

i used the newest exe to load the dll when i build it doesn't work

am i suppose to modify the "?"
in hDC dd ? because i didn't and its not working

i.e not making background transparent

I've also attached the compiled dll, which I tested with the new exe, and it works perfectly. If you still can't get it to work, just give up.

naruto you're supposed to describe your problem (ie what exactly happens/doesn't work).
