Hi.
Im tiling an image that is originally 400x1600 pixels, but in order to show it fully in the tileview i have to set the size to 5000x20000, why is that?
I need to place markers but i want to know the exact amount the tileview upscales the image in size.

what version of the library are you using?

MoeBro commented

V3. Im using your demo app but with my own pictures etc

So you're saying you have to blow up your image before creating tiles? What size and density is the screen you see this happening on?

MoeBro commented

Hmm im using the Nexus 5x emulator but its the same even on a new android phone.
Spec sheet says 5.2" 1080x1920 pixels.
I dont blow up the image. i tile the image to tiles that are 20 pixels by 20 pixels, but for some reason i have to set the size of the tileview to a way bigger size than the original image

Should not have to. Can you put your project somewhere I can see it? I can look this weekend

MoeBro commented

I can kind of make due with scaling my coordinates to match the tileview size, since i need the project tomorrow for testing something, but i can put it all somewhere so you can take a look.
