Ell	c4a201eaf4	Issue #5208 - paint brush is broken when aspect ratio is set to negative ... Fix horizontal downscaling of brush mipmap levels with odd width. We'd previously fail to skip the last pixel of each input row, which isn't included in the output when the width is odd, causing subsequent output rows to be shifted to the right.	2020-06-12 17:30:28 +03:00
Ell	30e925065f	app: fix gimp_brush_mipmap_get_memsize() ... Don't include the main mask/pixmap buffer size -- it's already counted in gimp_brush_get_memsize().	2020-02-13 16:56:33 +02:00

Ell	ee39f0ec13	app: use mipmaps when downscaling raster brushes ... When downscaling raster brushes, we currently resample the original brush with no fitlering (other than bilinear interpolation), which results in very noticable aliasing when using heavily downscaled big brushes. This commit constructs a box-filtered mipmap hierarchy for the original brush on-demand, and the closest mipmap is used as the resampling source for downscaled brushes, significantly improving the output quality.	2020-02-13 00:03:22 +02:00
