SETUP_MENU ICON的制作 1.制作ICON的bmp图。位图的颜色:采用颜色表palette_16color_setup（h/osd_pal_rgb_32b.h）中定义的颜色(16色)画图.背景颜色要求是十六色中的第六种颜色。2. 用工具(如：ImgFontTrans.exe)将保存所要制作的字的位图转换为点阵文件。Exp. ImgFontTrans.exe-在file中选择第一项:load 256 color bmp file）。再将其保存为你需要的点阵文件名（在file中选择最后一项:save bmp row data）.在该文件夹中便生成点阵文件。即：file- load 256 color bmp file- save bmp row data3. 将生成的点阵加入icon.c中，如果生成的点阵中未包含HEAD信息，必须在点阵的最上面多加一行： 0x28 0x20 0x10 icon宽 icon高 固定值注意：我们的程式中用的是16色的颜色表，1 位图一定要16色，而且每一种颜色都必须是程式中palette_16color_setup中所定义的颜色。2 生成的点阵必须要在最上面一行添加点阵的宽和高。Ep:一、有位图16色（40*32）A.bmp:我们用的type2使用的16色颜色表是palette_16color_setup（h/osd_pal_rgb_32b.h）定义的颜色，分别是： G B R A _palette4F( 150, 210, 140, 0xe0)/0 _palette4F( 10, 10, 10, 0xff),/1 _palette4F( 243, 243, 243, 0xff),/2 _palette4F( 132, 132, 132, 0xf0),/3 _palette4F( 10 , 255, 22, 0xff),/4 G B R A_palette4F( 163, 70, 255, 0xc0),/5 _palette4F( 179 , 225, 136, 0xe0),/6 背景色 _palette4F( 255, 0, 255, 0xff),/7 _palette4F( 180, 43, 21, 0xff),/8 _palette4F( 180, 44, 142, 0xff),/9 _palette4F( 80, 0, 160, 0xff),/10 _palette4F( 0, 70, 0, 0xff),/11 _palette4F( 30, 30, 245, 0xff),/12 _palette4F( 192, 192, 192, 0xe0),/14 CLUTE_TRANS,/15A：是指各颜色的透明度，0x00：全透明，0xff：全不透明表中的位置/1、/2是palette_16color_setup这个table的位置，在我们的程式中，setup_menu的其他部分（如表头是/0，背景色是/06）调用。我们做icon用的颜色只需要保证是上面表中的颜色就可以了。如果客户提供现有1张bmp图，这张图用的颜色表与我们颜色表不一样，而客户要求颜色不能改的话，我们可以先按照我们的颜色表建立一张颜色与该图的色调相近的图片，再将新建图与现有的图用画图板打开，将现有的图copy覆盖新建的图中，画图板会自动使用我们的颜色表将该图的颜色转换成与之相近的颜色。这样就可以保证该图的颜色与我们使用颜色表一样，而且相对原来的图片的颜色又相近。如果我们不修改美工给的bmp图的话，就需要重新开一个region,这样的话，就要在程式的很多地方做修改，所以最好还是先给客户我们使用的颜色表，请美工按照我们给的颜色表内的颜色画图，这样的话也就能保证能完全按照他们给的图做icon。二、画图：用photoshop按照我们的颜色表画图的步骤如下：1. 可以先用画图板新建一16色的位图（任意颜色）。再用photoshop打开该图。2. 图象-模式 新建bmp图时，系统会默认是RGB颜色，必须从RGB颜色转换到索引颜色。从RGB转换到索引颜色就可以到下图：选择自定义项就可以索引16色的颜色，可以选择颜色表。下图：可以选择每一种颜色的RGB值。可以把我们的颜色表中的RGB值填进去，这样就能保证位图的颜色就的我们颜色表中的颜色。G B R A如调色盘_palette4F( 243, 243, 243, 0xff), /2就在相应的R、G、B的地方填上相应的数字。3. 如果没有按照我们的颜色表，已经画好bmp图了，我们只能根据图的色调，在photoshop中选中色调相近的颜色，新建任意一图片，然后用画图板打开，将客户提供的图片copy，直接覆盖我们新建的图片。这样，该图就会自动按照我们的颜色表中的颜色调整，可能颜色会有点小的变化。不过这样也是最好的办法了。4.这样就可以生成我们icon可以用来转成点阵的bmp图。三、用工具ImgFontTrans.exe转换出来的点阵是：0x28
