C++ (Cpp) validate_pixels_ctable Exemples

Exemple #1

Fichier : SkPixelRef.cpp Projet : kidundead/skia

void SkPixelRef::setPreLocked(void* pixels, size_t rowBytes, SkColorTable* ctable) {
    SkASSERT(pixels);
    validate_pixels_ctable(fInfo, ctable);
    // only call me in your constructor, otherwise fLockCount tracking can get
    // out of sync.
    fRec.fPixels = pixels;
    fRec.fColorTable = ctable;
    fRec.fRowBytes = rowBytes;
    fLockCount = SKPIXELREF_PRELOCKED_LOCKCOUNT;
    fPreLocked = true;
}

Exemple #2

Fichier : SkPixelRef.cpp Projet : mariospr/chromium-browser

// Increments fLockCount only on success
bool SkPixelRef::lockPixelsInsideMutex() {
    fMutex->assertHeld();

    if (1 == ++fLockCount) {
        SkASSERT(fRec.isZero());
        if (!this->onNewLockPixels(&fRec)) {
            fRec.zero();
            fLockCount -= 1;    // we return fLockCount unchanged if we fail.
            return false;
        }
    }
    validate_pixels_ctable(fInfo, fRec.fPixels, fRec.fColorTable);
    return fRec.fPixels != NULL;
