MTK圖形圖象函數(shù)

1、S32gdi_image_draw_id(S32offset_x,S32

offset_y,U16image_id);offset_x和offset_y是圖片左上角的坐標(biāo),image_id是指向圖片的枚舉類型,用法如下:ADD_APPLICATION_IMAGE(MAIN_MENU_MATRIX_PHONEBOOK_ICON,CUST_IMG_PATH"\\\\MainLCD\\\\MainMenu\\\\MATRIX\\\\MM_PB.gif");2、S32gdi_image_draw(S32offset_x,S32offset_y,U8*image_ptr);Image_ptr是用file2hex.exe轉(zhuǎn)化后的圖片文件名；在MTK平臺里，image_ptr=(U8*)GetImage(image_id);3、S32gdi_image_draw_file(S32offset_x,S32offset_y,S8*image_name);Image_name是圖片的文件名；4、S32gdi_image_get_dimension_id(U16image_id,S32*width,S32*height);S32gdi_image_get_dimension_file(S8*image_name,S32*width,S32*height);S32gdi_image_get_dimension(U8*image_ptr,S32*width,S32*height);獲得圖片的長寬參數(shù)5、S32gdi_image_get_frame_count_id(U16image_id,S32*frame_count);S32gdi_image_get_frame_count_id(U16image_id,S32*frame_count);獲得動態(tài)圖片的幀數(shù)畫點(diǎn)函數(shù);6、voidUI_putpixel(s32x,s32y,colorc);7、關(guān)于剪切矩形:voidUI_set_clip(s32x1,s32y1,s32x2,s32y2);voidUI_reset_clip(void);voidUI_pop_clip(void);voidUI_set_text_clip(s32x1,s32y1,s32x2,s32y2);voidUI_reset_text_clip(void);voidUI_pop_text_clip(void);畫線函數(shù);顏色為c的一條直線：voidUI_line(s32x1,s32y1,s32x2,s32y2,colorc);顏色為c,寬度為w的一條直線：voidUI_wline(s32x1,s32y1,s32x2,s32y2,colorc,s32w);畫一個空心矩形:voidUI_draw_rectangle(s32x1,s32y1,s32x2,s32y2,colorc);填充一個矩形:voidUI_fill_rectangle(s32x1,s32y1,s32x2,s32y2,colorc);畫圖區(qū)域控制函數(shù):voidUI_lock_double_buffer(void);voidUI_unlock_double_buffer(void);voidUI_BLT_double_buffer(s32x1,s32y1,s32x2,s32y2);文字輸出有關(guān)的函數(shù):設(shè)置字符顯示區(qū):voidUI_set_text_clip(s32x1,s32y1,s32x2,s32y2);設(shè)置字體顏色:voidUI_set_text_color(colorc);設(shè)置字體邊框顏色:voidUI_set_text_border_color(colorc);設(shè)置當(dāng)前光標(biāo)位置:voidUI_move_text_cursor(s32x,s32y);獲取字符串的長、寬參數(shù):voidUI_measure_string(UI_string_typetext,s32*width,s32*height);獲得單個字符的長、寬參數(shù):voidUI_measure_character(UI_character_typec,s32*width,s32*height);輸出字符串:voidUI_print_text(UI_string_typetext);輸出一個字符:voidUI_print_character(UI_character_typec);字符串求長:U16UTF8Strlen(U8*p);字符串操作函數(shù):字符串查找：strstr字符串拷貝：strcpy字符串定長拷貝：strncpy字符串比較：strcmp字符串定長比較：strncmp字符串續(xù)接：strcat字符串定長續(xù)接：strncat字符串轉(zhuǎn)化為整型函數(shù):atoi整型轉(zhuǎn)化為字符串函數(shù):itoa關(guān)于層建立一個層:GDI_RESULTdm_create_layer_using_outside_memory(S32x,S32y,S32width,S32height,gdi_handle**handle_ptr,U8*outside_memory,S32outside_memory_size,U32flags);忖督平臺上,軟件支持四層。獲取baselayer,即最下面的層：GDI_RESULTgdi_layer_get_base_handle(gdi_handle*handle_ptr);將層壓棧并激活,執(zhí)行此條語句后,可以對該層操作,voidgdi_layer_push_and_set_active(gdi_handlehandle);操作完成后,用下面的函數(shù)讓該層出棧:voidgdi_layer_pop_and_restore_active(void);最后用函數(shù)GDI_RESULTgdi_layer_set_blt_layer_ext(gdi_handlehandle0,gdi_handlehandlel,gdi_handlehandle2,gdi_handle
