From 916b44e361f275555c5f22b9d91c973ccc089037 Mon Sep 17 00:00:00 2001 From: Manolo Gouy Date: Mon, 19 Mar 2018 17:43:18 +0000 Subject: New member function Fl_Image::scale(int width, int height) to set the FLTK size of an image. Each image has now two sizes implemented as follows: - the pixel size is stored in private members pixel_w_ and pixel_h_ with public accessors pixel_w() and pixel_h() - the FLTK size is stored in private members w_ and h_ and read by w() and h() - when the image is constructed, the two sizes have the same value - the protected w(int) and h(int) member functions set both FLTK and pixel sizes. - the public scale(int, int) member function is essentially nothing but set the FLTK size and don't change the pixel size. - when the image is drawn, its FLTK size determines how big it is drawn, its pixel size determines how much data are available to draw it. FLTK 1.3.4 with FL_ABI_VERSION=10304 contained an equivalent member function but only for the Fl_Shared_Image class. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12776 ea41ed52-d2ee-0310-a9c1-e6b18d33e121 --- FL/Fl_Graphics_Driver.H | 8 +++----- 1 file changed, 3 insertions(+), 5 deletions(-) (limited to 'FL/Fl_Graphics_Driver.H') diff --git a/FL/Fl_Graphics_Driver.H b/FL/Fl_Graphics_Driver.H index b2c15272a..c1588703b 100644 --- a/FL/Fl_Graphics_Driver.H +++ b/FL/Fl_Graphics_Driver.H @@ -141,9 +141,9 @@ protected: matrix *fl_matrix; /**< Points to the current coordinate transformation matrix */ virtual void global_gc(); /** Support function for Fl_Pixmap drawing */ - virtual fl_uintptr_t cache(Fl_Pixmap *img, int w, int h, const char *const*array) { return 0; } + virtual fl_uintptr_t cache(Fl_Pixmap *img) { return 0; } /** Support function for Fl_Bitmap drawing */ - virtual fl_uintptr_t cache(Fl_Bitmap *img, int w, int h, const uchar *array) { return 0; } + virtual fl_uintptr_t cache(Fl_Bitmap *img) { return 0; } /** Support function for Fl_RGB_Image drawing */ virtual void uncache(Fl_RGB_Image *img, fl_uintptr_t &id_, fl_uintptr_t &mask_) { } // --- implementation is in src/drivers/xxx/Fl_xxx_Graphics_Driver_image.cxx @@ -173,7 +173,6 @@ protected: the image offset by the cx and cy arguments. */ virtual void draw(Fl_Bitmap *bm, int XP, int YP, int WP, int HP, int cx, int cy) {} - virtual void draw(Fl_Shared_Image *shared, int X, int Y); virtual void copy_offscreen(int x, int y, int w, int h, Fl_Offscreen pixmap, int srcx, int srcy); /** Support function for image drawing */ @@ -393,7 +392,7 @@ public: virtual const char *font_name(int num) {return NULL;} /** Support for Fl::set_font() */ virtual void font_name(int num, const char *name) {} - /** Support function for Fl_Shared_Image drawing */ + // Draws an Fl_Image scaled to width W & height H virtual int draw_scaled(Fl_Image *img, int X, int Y, int W, int H); /** Support function for fl_overlay_rect() and scaled GUI.
