Vladimír Vondruš 3497985526 Shaders: update DistanceFieldVector test files with fixed SDFs. The output is now much closer to the Vector shader output (mean difference went from ~6 to 1.79), and in the multi-draw case it's clearly visible that it's no longer slightly weirdly uneven. The test files are now also much smaller as the originals were created before RLE was implemented in TgaImageConverter.		3 years ago

Common shader test files

The *-texture.tga files are exported quadrants from checkerboard.svg with various layers enabled, saved either as three-channel or four-channel PNG of 128x128 pixels and then converted to TGA via magnum-imageconverter (so the shader tests don't need any external plugins) --- if everything is correct, the RGB files will be 48 kB and the RGBA ones 64 kB.

The vector.tga file is exported from magnum/doc/generated/vector.svg as 128x128, converted to a single-channel format via ImageMagick:

convert vector.png -flatten -colorspace Gray vector-r.png

and then to a single-channel (16 kB) TGA via magnum-imageconverter. Then, this file is converted to a SDF via

magnum-distancefieldconverter --output-size "64 64" --radius 16 vector.tga vector-distancefield.tga
