提供一个可以转出图片的函数,但是转出来的图片会模糊,暂时不知道怎么解决
func (p *Page) Convert2Image() image.Image { // Render the PDF file width, height := p.Size() surface := cairo.NewSurface(cairo.FORMAT_ARGB32, int(width), int(height)) pattern := cairo.NewPatternForSurface(surface) pattern.SetFilter(cairo.CAIRO_FILTER_NEAREST) defer pattern.Destroy() _, drawcontext := surface.Native() surface.SetSource(pattern) C.poppler_page_render_for_printing(p.p, (*C.cairo_t)(unsafe.Pointer(drawcontext))) defer surface.Finish() return surface.GetImage() }
可以运行,报错
