would this be the corect way to draw to a IDirect3DTexture8

I need to load PCX files to an IDirect3DTexture8, so far I have only found fairly vaige references on how to do this, so I am wondering is this the corect method for geting pixel(X,Y) of a IDirect3DTexture8 set to the color of my chooseing? if (D3D_OK != D3DXCreateTexture(g_pDevice, x, y, 1, 0, D3DFMT_A8R8G8B8, D3DPOOL_MANAGED, &d3dtexture))MessageBox(NULL, "texture creation failed", "!", MB_OK); D3DLOCKED_RECT img_rec; D3DSURFACE_DESC surf_desc; d3dtexture->GetLevelDesc(0,&surf_desc); if(surf_desc.Format == D3DFMT_A8R8G8B8){ //d3dtexture->UnlockRect(0); if (D3D_OK != d3dtexture->LockRect(0, &img_rec, NULL, D3DLOCK_NOSYSLOCK ))MessageBox(NULL, "lock failed", "!", MB_OK); //DWORD color; struct temp_color{ BYTE b; BYTE g; BYTE r; BYTE a; } *pix; temp_color temp; temp.b = 128; temp.g = 128; temp.r = 128; temp.a = 128; // DWORD *pix; // DWORD temp = 0; pix = (temp_color *)img_rec.pBits; int pitch = img_rec.Pitch; // pix[0] = 0; int place = 0; for(i = 0; i<y; i++){ for(j = 0; j<x; j++){ place = (i*pitch)+j; pix[place] = temp; } } d3dtexture->UnlockRect(0); } ok lets just get the thing filled with a color first so someone give me code that would fill out a IDirect3DTexture8 (of x,y dimentions) with grey pixels, includeing the ability to set a specific pixel to any arbitrary color [edited by - Bobboau on January 28, 2003 2:16:12 PM]

never mind I figured it out

  					if(((j)%x == 0) && (j>0)){//if we''ve hit the end of the line						offset++;						if(!bts==((bts/2)*2)){						offset++;						offset+=bts-pcx_file->head.BytesPerLine;						}						bts=0;					}else{						bts++;					}

Bobboau, bringing you products that work... in theory
