Isometric Preset 64x32 Export

[Redspark]

Hi,

I'm fairly new to Affinity Designer.  I've mostly used Inkscape.  I'm trying to use it to create Isometric tiles for a game.  My Document units is set to pixels.  When I use the Preset 64x32 Isometric grid, I had expected that the resulting tiles would be 64px by 32px.  But when I draw a tile with the pen tool, it is much larger.  So I played with the settings for the Isometric 2:1 setting until the tile reads 64x32px.  However, now when I go to export a single tile, the dimensions are one or more pixels larger.

What is the proper way, if there is a way to do this, to setup a 2:1 Isometric grid that exports to 64x32px exactly for each tile?  Also, tiles should not bleed over top of each other.  When I check in Pixel View, it looks like adjacent tiles will bleed into each other with Anti-Aliased pixels.  Is there a way to prevent this?  

Thanks.

Are you using a centred stroke  on vectors?

I have a dedicated object for the outline of the tile and the stroke on it is set to Inside.

Hi @Redspark,
Welcome to Affinity Forums
It's possible something is extending beyond the tile - some layer effects applied to the content of the tile or similar things. Can you attach a simplified file with one of these tiles that fails to export with the correct dimensions? Thanks.

Attached is a simple example.  Each time I export a selected tile as a PNG or PSD, the result doesn't look right.  The image dimensions is either the wrong size or the tile doesn't take up the correct space that I would want.  When it is a vector, it looks exactly what I want. But when it is rendered to pixels, the Antialiasing seems to change the size.  Any advice would be appreciated.  Thanks.

This is happening because the tiles do not fit on 64x32px exactly. Go to Affinity Designer Preferences, User Interface section, Decimal Places for Units Types and set the Pixels value to 2 or more, then check the Transform panel again - you will see the width and height are not integer values thus they end up adding an additional pixel to the dimensions of the exported file.

Thanks.  I'll try to fiddle with the grid some more unless you know of a way to get it to be exactly integer pixels.
