I have a question. I have a local version of Tiled that I use for some extra things I want to try. One of these things was changing the behavior of an ImageLayer and `repeatX` as seen in the pic (mountains at the bottom).
This works but for what I need, I want mapobjects tile its textures when repeatX is clicked (Image circled in red). I have been banging my head against the wall looking for the code that draw’s these images and sets the brush so that `Qt::TexturePattern` can be enabled / tested. Before I traverse this trail, in Tiled’s current structure, is this even possible? Thanks.

Yes, it’s of course possible, since as you found out the image layers already provide this functionality. 🙂
The trick is in `MapRenderer::drawImageLayer`, which calls `painter->setBrush` with the (tinted) image associated with the layer. By setting the image as a brush and then drawing a rectangle, we get a tiled pattern almost for free (this way, it even works when due to zooming out very far, there are a huge amount of instances of the image visible).

Thank you for your help!

Ugh! After adding the repeatX/Y properties, I think I hit a snag. I don’t think I can support tiling in a vertical or horizontal direction alone. I believe it will tile both directions automatically. I have a feeling I might be wrong and just too new to Qt. ☹

What should happen in the other direction then? Stretching the image? I think you can to do that by applying a scale on one axis and limiting the rectangle you’re drawing to the size of the image in the respective dimension.

Edit:
I did consider buffered drawing(?), but that seems resource heavy. I could draw to a buffer / painter(??) with excatly what you suggested and then `blit` (I know 🙄 ) that onto the surface stretching only the dimension that should be stretched.
Stretching is what I figured should be the outcome, but that seems to be more than I need. tiling equally is plenty.
Besides, `CallRenderer::render(..)` supports so much (beyond objects) and it feels daunting at my current level. 🙂
This feature is really just visual sugar for my map building. I already support it in my game thru GLSL/shaders. I have added very llimited, basic support via:
UPDATE: I’m done for now. This will have to do for personal use. Thanks.
```c++
if (object->isTiling()) {
bool flippedHorizontally = cell.flippedHorizontally();
bool flippedVertically = cell.flippedVertically();
double rotation = 0; // Not sure it's required
if (cell.flippedAntiDiagonally()) { // Not sure it's required
rotation = 90;
flippedHorizontally = flippedVertically;
flippedVertically = !cell.flippedHorizontally();
}
const QTransform oldTransform = painter->transform();
QTransform transform = oldTransform;
transform.rotate(rotation);
transform.translate(flippedHorizontally ? object->width() : 0,
flippedVertically ? object->height() : 0);
transform.scale(flippedHorizontally ? -1 : 1, flippedVertically ? -1 : 1);
painter->setTransform(transform);
painter->setBrush(cell.tile()->image());
painter->setPen(Qt::NoPen);
painter->drawRect(bounds);
painter->setTransform(oldTransform);
} else {
CellRenderer(painter, this, object->objectGroup()->effectiveTintColor())
.render(cell, QPointF(), bounds.size());
}
```
As seen above, I hard-code the drawing, which seems wrong since you are using fragments to draw onto the surface. This causes complications with full integration into your system which already handles all transformations.

I understand that adding the tiling feature to `CallRenderer::render` will end up being rather too complicated, and it makes sense to bypass it entirely for rendering tiling tile objects. Good job on getting it done for your own purposes!
