AddBitmapToMenuItem()

void AddBitmapToMenuItem	(	wxMenuItem *	aMenu,
		const wxBitmap &	aImage
	)

Add a bitmap to a menuitem.

It is added only if use images in menus config option allows it. For wxITEM_CHECK or wxITEM_RADIO menuitems, the bitmap is added only on Windows, other platforms do not support it

Parameters

aMenu	is the menuitem.
aImage	is the icon to add to aMenu.

Definition at line 240 of file bitmap.cpp.

{
    // Retrieve the global application show icon option:
    bool useImagesInMenus = Pgm().GetCommonSettings()->m_Appearance.use_icons_in_menus;

    wxItemKind menu_type = aMenu->GetKind();

    if( useImagesInMenus && menu_type != wxITEM_CHECK && menu_type != wxITEM_RADIO  )
    {
        aMenu->SetBitmap( aImage );
    }
}

KiScaledBitmap() [1/2]

wxBitmap KiScaledBitmap	(	BITMAPS	aBitmap,

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

KiScaledBitmap() [2/2]

wxBitmap KiScaledBitmap	(	const wxBitmap &	aBitmap,

aWindow	target window for scaling context

SaveCanvasImageToFile()

bool SaveCanvasImageToFile	(	EDA_DRAW_FRAME *	aFrame,
		const wxString &	aFileName,
		BITMAP_TYPE	aBitmapType = BITMAP_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 existing 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.
