From 9e3393a624d3c9d7e0a7f5c8bedbd3eb0d1e1b42 Mon Sep 17 00:00:00 2001 From: Hugo Locurcio Date: Sun, 19 Jan 2020 23:21:49 +0100 Subject: [PATCH] Optimize the editor icon generation Icons are no longer upsampled when using an integer editor scale. This makes some icons slightly less crisp, but the icons themselves can be adjusted to mitigate this. When using a non-integer editor scale setting, upsampling is kept as it improves crispness in a far more visible manner. When upsampling is disabled, this speeds up the theme generation by about 100 ms on average, making the project manager and editor start slightly faster. This also speeds up switching between themes. --- editor/editor_themes.cpp | 99 ++++++++++++++++++-------------- modules/svg/image_loader_svg.cpp | 13 +++-- 2 files changed, 64 insertions(+), 48 deletions(-) diff --git a/editor/editor_themes.cpp b/editor/editor_themes.cpp index 621f5316876..8037045e773 100644 --- a/editor/editor_themes.cpp +++ b/editor/editor_themes.cpp @@ -89,7 +89,11 @@ Ref editor_generate_icon(int p_index, bool p_convert_color, float // dumb gizmo check bool is_gizmo = String(editor_icons_names[p_index]).begins_with("Gizmo"); - ImageLoaderSVG::create_image_from_string(img, editor_icons_sources[p_index], p_scale, true, p_convert_color); + // Upsample icon generation only if the editor scale isn't an integer multiplier. + // Generating upsampled icons is slower, and the benefit is hardly visible + // with integer editor scales. + const bool upsample = !Math::is_equal_approx(Math::round(p_scale), p_scale); + ImageLoaderSVG::create_image_from_string(img, editor_icons_sources[p_index], p_scale, upsample, p_convert_color); if ((p_scale - (float)((int)p_scale)) > 0.0 || is_gizmo || p_force_filter) icon->create_from_image(img); // in this case filter really helps @@ -106,7 +110,15 @@ Ref editor_generate_icon(int p_index, bool p_convert_color, float void editor_register_and_generate_icons(Ref p_theme, bool p_dark_theme = true, int p_thumb_size = 32, bool p_only_thumbs = false) { #ifdef SVG_ENABLED + // The default icon theme is designed to be used for a dark theme. + // This dictionary stores color codes to convert to other colors + // for better readability on a light theme.
