Returns

wxBitmap* - caller owns it.

KiScaledBitmap() [1/2]

wxBitmap KiScaledBitmap	(	BITMAPS	aBitmap,
		wxWindow *	aWindow,
		int	aHeight = -1
	)

Construct a wxBitmap from a memory record, scaling it if device DPI demands it.

Internally this may use caching to avoid scaling the same image twice. If caching is used, it's guaranteed threadsafe.

Parameters

aBitmap	is from the BITMAPS enum in bitmaps_list.h
aWindow	target window for scaling context
aHeight	is the requested image height for the source bitmap, or -1 for any height

Definition at line 147 of file bitmap.cpp.

{
    // Bitmap conversions are cached because they can be slow.
    const int scale = get_scale_factor( aWindow );

    SCALED_BITMAP_ID id = { static_cast<BITMAPS>( aBitmap ), scale };

    std::lock_guard<std::mutex> guard( s_BitmapCacheMutex );
    auto it = s_ScaledBitmapCache.find( id );

    if( it != s_ScaledBitmapCache.end() )
    {
        return it->second;
    }
    else
    {
        wxBitmap bitmap = GetBitmapStore()->GetBitmapScaled( aBitmap, scale, aHeight );
        return s_ScaledBitmapCache.emplace( id, bitmap ).first->second;

KiScaledBitmap() [2/2]

wxBitmap KiScaledBitmap	(	const wxBitmap &	aBitmap,
		wxWindow *	aWindow
	)

Overload of the above function that takes another wxBitmap as a parameter.

Parameters

aBitmap	is the source bitmap to scale
aWindow	target window for scaling context

Definition at line 176 of file bitmap.cpp.

{
    const int scale = get_scale_factor( aWindow );

    if( scale == 4 )

SaveCanvasImageToFile()

bool SaveCanvasImageToFile	(	EDA_DRAW_FRAME *	aFrame,
		const wxString &	aFileName,
		wxBitmapType	aBitmapType = wxBITMAP_TYPE_PNG
	)

Save the current view as an image file.

Parameters

aFrame	The current draw frame view to save.
aFileName	The file name to save the image. This will overwrite an exisiting file.
aBitmapType	The type of bitmap create as defined by wxImage.

Returns

True if the file was successfully saved or false if the file failed to be saved.
