drawImageRect not working with SkImages::BorrowTextureFrom / GrBackendTextures::MakeVk

[Kalen White]

I am drawing this VkImage already on my app, its already transitioned to SHADER_READ_ONLY, and so its ready to be used by skia. 100% the case, its a valid texture, and it works already.  It's in the correct transition state of SHADER_READ_ONLY. 

I am giving it the proper coordinates (replaced with a fill box, which paints perfectly)

none sk_draw_fill_preserve(sk a) {

SkCanvas* sk = (SkCanvas*)a->sk_canvas;

draw_state ds = (draw_state)last(a->state);

SkPaint paint;

paint.setStyle(SkPaint::kFill_Style);

if (ds->blur_radius > 0.0f)

paint.setMaskFilter(SkMaskFilter::MakeBlur(kNormal_SkBlurStyle, ds->blur_radius));

paint.setColor(ds->fill_color);

paint.setAntiAlias(true);

if (ds->tx) {

GrDirectContext* direct_ctx = a->skia->ctx.get();

texture tx = ds->tx;

GrVkImageInfo vk_info = {};

vk_info.fImage = tx->vk_image; // 0x0000510000000051 (same one used successfully given to a frosted blur shader, which works

vk_info.fImageLayout = VK_IMAGE_LAYOUT_SHADER_READ_ONLY_OPTIMAL;

vk_info.fImageTiling = VK_IMAGE_TILING_OPTIMAL;

vk_info.fFormat = tx->vk_format; // VK_FORMAT_B8G8R8A8_UNORM

vk_info.fLevelCount = 1;

GrBackendTexture backendTex = GrBackendTextures::MakeVk(tx->width, tx->height, vk_info);

sk_sp<SkImage> sk_image = SkImages::BorrowTextureFrom(

direct_ctx,

backendTex,

kTopLeft_GrSurfaceOrigin,

kRGBA_8888_SkColorType,

kPremul_SkAlphaType,

nullptr

);

SkRect dst = SkRect::MakeXYWH(ds->x, ds->y, ds->w, ds->h);

SkSamplingOptions sampling(SkFilterMode::kLinear, SkMipmapMode::kNone);

//paint.setColor(SK_ColorWHITE); // <-- this works

//sk->drawRect(dst, paint); // below, we get zero result.

sk->drawImageRect(sk_image, dst, sampling, &paint);

sk_sync(); // <-- ensuring a flush here right away

} else

sk->drawPath(*(SkPath*)a->sk_path, paint);

}

Theres no Vk Validation errors to this, either. (they are enabled) 

It just doesnt paint on my window like the White rectangle does in the same transform.

This doesn't answer your question sadly, but I have a question. Do you need to have a vkImage at all or not? Having trouble drawing a white square to my GTK-Application, because I am not feeding it into cairo at all.
