Detailed Description

This class handle bitmap images in KiCad.

It is not intended to be used alone, but inside another class so all methods are protected or private. It is used in SCH_BITMAP class, WS_DRAW_ITEM_BITMAP, and possibly others in the future.

Warning: Not all plotters are able to plot a bitmap. Mainly GERBER plotters cannot.

◆ GetScalingFactor()

double BITMAP_BASE::GetScalingFactor ( ) const

inline

This scaling factor depends on m_pixelSizeIu and m_scale.

m_pixelSizeIu gives the scaling factor between a pixel size and the internal units. m_scale is an user dependent value, and gives the "zoom" value.

m_scale = 1.0 = original size of bitmap.
m_scale < 1.0 = the bitmap is drawn smaller than its original size.
m_scale > 1.0 = the bitmap is drawn bigger than its original size.

Returns: The scaling factor from pixel size to actual draw size.
