Value:

    do {\
    float isx = ((i - max_supp) + b->roi->x)/b->roi->scale;\
    float isy = ((j - max_supp) + b->roi->y)/b->roi->scale;\
    /* isx against the WIDTH, isy against the HEIGHT. This read `isy >= b->buf->width`,
       which never bounds-checked isx at all and tested isy twice. The comment above says
       what the test is for -- "if not out of buf" -- so the intent is unambiguous. It is
       not a memory-safety bug, because both coordinates are CLAMPed in the else branch,
       but it picks the wrong branch: a pixel past the right edge sampled the preview with
       px clamped to the last column instead of taking the hi-res fallback, and on a
       portrait image every row below `width` took the fallback instead of the preview. */\
    if(isx < 0 || isx >= b->buf->width\
    || isy < 0 || isy >= b->buf->height)\
      out[*wd2*j+i] = (fallback);\
    else\
    {\
      int px = CLAMP(isx / (float)b->buf->width  * b->wd + (b->pwd-b->wd)/2, 0, b->pwd-1);\
      int py = CLAMP(isy / (float)b->buf->height * b->ht + (b->pht-b->ht)/2, 0, b->pht-1);\
      out[*wd2*j+i] = b->pad0[b->pwd*py+px];\
