@@ -41,6 +41,22 @@ HOW TO UPDATE?
Breaking changes:
- Image: removed 'tint_col' and 'border_col' parameter from Image() function. (#8131, #8238)
- Old function signature:
void Image (ImTextureID tex_id, ImVec2 image_size, ImVec2 uv0 = (0,0), ImVec2 uv1 = (1,1), ImVec4 tint_col = (1,1,1,1), ImVec4 border_col = (0,0,0,0));
- New function signatures:
void Image (ImTextureID tex_id, ImVec2 image_size, ImVec2 uv0 = (0,0), ImVec2 uv1 = (1,1));
void ImageWithBg(ImTextureID tex_id, ImVec2 image_size, ImVec2 uv0 = (0,0), ImVec2 uv1 = (1,1), ImVec4 bg_col = (0,0,0,0), ImVec4 tint_col = (1,1,1,1));
- TL;DR: 'border_col' had misleading side-effect on layout, 'bg_col' was missing, parameter order couldn't be consistent with ImageButton().
- New behavior always use ImGuiCol_Border color + style.ImageBorderSize / ImGuiStyleVar_ImageBorderSize.
- Old behavior altered border size (and therefore layout) based on border color's
alpha, which caused variety of problems.
- Old behavior used a fixed value of 1.0f for border size which was not tweakable.
- Kept legacy signature (will obsolete), which mimics the old behavior,
but uses Max(1.0f, style.ImageBorderSize) when border_col is specified.
- Added ImageWithBg() function which has both 'bg_col' (which was missing) and 'tint_col'.
It was impossible to add 'bg_col' to Image() with a parameter order consistent with
other functions, so we decided to remove 'tint_col' and introduce ImageWithBg().
- Renamed ImFontConfig::GlyphExtraSpacing.x option to GlyphExtraAdvanceX. (#242)
- Renamed style.TabMinWidthForCloseButton to style.TabCloseButtonMinWidthUnselected.
- Backends: Vulkan: Added 'uint32_t api_version' argument to ImGui_ImplVulkan_LoadFunctions().
