Use simple syntax
Solid Color Brush: Fill=“#FFFFFF”
Path: Data=“M0,0 h100v100h-100z”
Use less costly representation
Single color image  solid color
Same color gradient  solid color
Image with same rows/columns  single row/column
Remove non-visible elements
Empty path, glyph elements
Opacity=0, totally clipped, out of bound, totally covered
Remove default value/redundancy
Opacity, BidiLevel, TileMode, StyleSimulation, IsSideways
Clipping larger than elements, same as paper bounds
Canvas with single child, no attributes
Glyphs.Indices optional for simple mapping and layout
Remove redundant paths/points in path geometry
Reuse elements and attributes
Resource and remote resource dictionary
Brushes, MatrixTransform, Path, Glyphs, Canvas
Use RenderTransform to create more reusable parts
Remove default value/redundancy
Opacity, BidiLevel, TileMode, StyleSimulation,
IsSideways
Clipping larger than elements, same as paper bounds

Glyphs.Indices optional for simple mapping and layout
Remove redundant paths/points in path geometry
Reuse elements and attributes
Resource and remote resource dictionary
Brushes, MatrixTransform, Path, Glyphs, Canvas
Use RenderTransform to create more reusable parts
Merge Glyphs/Path elements
Merge same size/font glyphs on the same line
Merge simple paths with the same stroking/filling
Merge tiled images
Replace simulated gradient fill with real gradient
More complex optimization
Brush algebra: (red, 0.5) * (red, 0.5) = (red, 0.75)
opacity1 * (rgb, opacity2) = (rgb, opacity1 * opacity2)
Selective rasterization
VisualBrush for hatching, stencils

Subset fonts, preferably per document
Remove/replace barely used fonts
Substitute fonts when not embeddable
Share glyph bitmaps/outlines
Font tables of limited usage
GSUB, GPOS, kern
EBDT, hdmx, vdmx
Consider rearrange glyph indices
Vista, simkai.ttf, 28,562 glyphs, 11 mb
Subset with围棋, 183k, 55k compressed
hmtx 58k, loca 57k, vmtx 57k, glyf 690b

Share duplicated images (crc32)
Stitch banded images
Single color/same row/same column image
Pick the right size, trim image
Pick the right color depth
Pick the right image format
Adjust compression
OpacityMask merge with brush, remove rgb
