Full graphic LCD custom welcome screen problems

So I have this full graphic lcd display for my printer, and I wanted to change the welcome screen to my own Bitmap image. It turns out you can only replace the byte array with an image the same size as the stock one, (60x64) and I wanted to change it to an image 128x64 pixels. How could i mess with the firmware to allow it for me to put in a welcome screen that takes up the whole area? For example, alot of people have tutorials on how to change the image, but they don't explain how to replace the image with one that takes up the whole screen.


This is what the Marlin firmware DOGMbitmaps.h looks like at first:

#define START_BMPWIDTH 	60	//Width in pixels
#define START_BMPHEIGHT 	64	//Height in pixels
#define START_BMPBYTEWIDTH 	8	//Width in bytes
const unsigned char start_bmp[574] PROGMEM = { //AVR-GCC, WinAVR

The first byte array is the welcome image, but it only takes up half of the screen. I want to replace it so that I can put in an image that takes up the whole screen. I already removed the text that appears on the right side of the welcome screen.

I just did that. You need to make a 128X64 image and do the lcd conversion.
You will modify top script to:

#define START_BMPWIDTH 128 //Width in pixels
#define START_BMPHEIGHT 64 //Height in pixels
#define START_BMPBYTEWIDTH 16 //Width in bytes

Then you will have to erase the welcome text in: dogm_lcd_implementation.h


// Welcome message
u8g.setFont(u8g_font_6x10_marlin);
u8g.drawStr(62,10,"MARLIN");
u8g.setFont(u8g_font_5x8);
u8g.drawStr(62,19,"V1.0.0 RC2");
u8g.setFont(u8g_font_6x10_marlin);
u8g.drawStr(62,28,"by ErikZalm");
u8g.drawStr(62,41,"DOGM128 LCD");
u8g.setFont(u8g_font_5x8);
u8g.drawStr(62,48,"enhancements");
u8g.setFont(u8g_font_5x8);
u8g.drawStr(62,55,"by STB");
u8g.drawStr(62,61,"uses u");
u8g.drawStr90(92,57,"8");
u8g.drawStr(100,61,"glib");

Don't erase this:

// RepRap init bmp
u8g.drawBitmapP(0,0,START_BMPBYTEWIDTH,START_BMPHEIGHT,start_bmp);
