From ea4bae5e68e3065ca159ea309a0f3325a06e7f35 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Micha=C5=82=20G=C3=B3rny?= Date: Fri, 26 Mar 2021 13:42:49 +0100 Subject: [PATCH] Increase image comparison limits Most of the tests require exact match which apparently doesn't always happen in non-pristine environments. Some of them have very big differences due to texlive font rendering changes. --- lib/matplotlib/tests/test_arrow_patches.py | 6 +++--- lib/matplotlib/tests/test_axes.py | 4 ++-- lib/matplotlib/tests/test_backend_pgf.py | 2 +- lib/matplotlib/tests/test_colorbar.py | 2 +- lib/matplotlib/tests/test_contour.py | 2 +- lib/matplotlib/tests/test_figure.py | 5 +++-- lib/matplotlib/tests/test_image.py | 2 +- lib/matplotlib/tests/test_legend.py | 6 +++--- lib/matplotlib/tests/test_lines.py | 3 ++- lib/matplotlib/tests/test_streamplot.py | 3 ++- lib/matplotlib/tests/test_units.py | 4 ++-- lib/matplotlib/tests/test_usetex.py | 1 + lib/mpl_toolkits/tests/test_axes_grid1.py | 2 +- 13 files changed, 23 insertions(+), 19 deletions(-) diff --git a/lib/matplotlib/tests/test_arrow_patches.py b/lib/matplotlib/tests/test_arrow_patches.py index 8d573b4adb..dfc42efcb9 100644 --- a/lib/matplotlib/tests/test_arrow_patches.py +++ b/lib/matplotlib/tests/test_arrow_patches.py @@ -67,7 +67,7 @@ def __prepare_fancyarrow_dpi_cor_test(): @image_comparison(['fancyarrow_dpi_cor_100dpi.png'], remove_text=True, -
