我用的是GIMP把PNG图片改成224色保存(打开GIMP,选图片,画像-模式-索引-224色—保存—ASCII,OK)
在到存放图片目录执行
pngtopnm default_wallpaper.png >logo_linux_clut224.pnm
pnmtoplainpnm logo_linux_clut224.pnm > logo_linux_clut224.ppm
将logo_linux_clut224.ppm放到linux-2.6.29/drivers/video/logo,
删除logo_linux_clut224.c和logo_linux_clut224.o
然后make zImage就可以了.
linux-2.6.29/drivers/video/fbmem.c
fb_do_show_logo函数:
393 static void fb_do_show_logo(struct fb_info *info, struct fb_image *image,
394 int rotate, unsigned int num)
395 {
396 unsigned int x;
397
398 int xoff,yoff;
399 xoff=(info->var.xres - num*fb_logo.logo->width 8)>>1;
400 yoff=(info->var.yres - num*fb_logo.logo->height 8)>>1;
401
402 if (rotate == FB_ROTATE_UR) {
403 for (x = 0;
404 x < num && image->dx image->width <= info->var.xres;
405 x ) {
406 image->dx = xoff;
407 image->dy = yoff;
408 info->fbops->fb_imageblit(info, image);
409 image->dy = image->height 8;
上述修改后有可能不能显示,解决办法修改显示logo的高度.
drivers/video/console/fbcon.c
fbcon_prepare_logo函数:
修改logo_height = fb_prepare_logo(info, ops->rotate);
logo_height = fb_prepare_logo(info, ops->rotate)+200; 本文出自 “LINUX && ANDROID” 博客,请务必保留此出处http://tianxiaolin.blog.51cto.com/1810342/602185
