capRenderSize()

QSize capRenderSize ( const QSize & renderSize, const QSize & requestedSize )

static

Clamps an svg render size so that rendering does not exceed a multiple of the requested size.

Rendering at the full native size of an svg just to scale it down afterwards wastes memory, and canvases with extreme coordinates can exceed Qt's rasterizer coordinate limit which makes Qt silently drop shapes from the rendered image.

Parameters

renderSize	The size the svg would be rendered at.
requestedSize	The size that was actually requested.

Returns

A size with the aspect ratio of renderSize whose longest side is at most four times the longest side of requestedSize.

getIconType()

QString getIconType ( const bool isBuddy, const UserLevelFlags & userLevelFlags, const QString & privLevel )

loadAndColorSvg()

QIcon loadAndColorSvg ( const QString & iconPath, const QString & colorLeft, const std::optional< QString > & colorRight, const int minSize )

static

Loads the usericon svg and fills in its colors. The image is kept as a QIcon to preserve the image quality.

Call icon.pixmap(w, h) in order to convert this icon into a pixmap with the given dimensions. Avoid scaling the pixmap in other ways, as that destroys image quality.

Parameters

minSize

If the dimensions of the source svg is smaller than this, then it will be scaled up to this size

loadSvg()

QPixmap loadSvg ( const QString & svgPath, const QSize & size, bool expandOnly = false )

static

Loads in an svg from file and scales it without affecting image quality.

Parameters

svgPath	The path to the svg file, with file extension.
size	The desired size of the pixmap.
expandOnly	If true, then keep the size of the initial pixmap to at least the svg size.

Returns

The svg loaded into a Pixmap with the given size, or an empty Pixmap if the loading failed.

setAttrRecur()

void setAttrRecur ( QDomElement & elem, const QString & tagName, const QString & attrName, const QString & idName, const QString & attrValue )

static

Updates tags in the svg

Parameters

elem	The svg
tagName	tag with attribute to update
attrName	attribute to be updated
idName	id that the tag has to match
attrValue	the value to update the attribute to

tryLoadImage()

QPixmap tryLoadImage ( const QString & path, const QSize & size, bool expandOnly = false )

static

Try to load path image from non-SVG formats, otherwise fall back to SVG. This is to allow custom themes to support non-SVG format type overrides, since SVG requires custom loading.

Parameters

path	The path to the file, with no file extension. File formats will be automatically detected.
size	The desired size of the pixmap.
expandOnly	If true, then keep the size of the initial pixmap to at least the size (Only relevant if SVG).

Returns

The loaded image into a Pixmap with the given size, or an empty Pixmap if the loading failed.
