US Zip Code overlay on Google Maps

Today I had a need to find out a set of zip codes that would match a delivery area for one of my customers. I was wondering how could I find out all the zip codes over a given area...

Searching a little bit I found a website named zipmap which actually does just that. The entire US is covered and you can navigate it just like you navigate a regular Google Map view. Very practical!

You can easily move around, zoom in and out, and you even see the map with street names in the background.

DefineFont2

/* DefineFont3 is the same as DefineFont2 */
typedef struct swf_definefont2 swf_definefont3;

It is common to use the DefineFont2 tag in order to create an array of shapes later re-used to draw strings of text on the screen. This tag must be used whenever a DefineEditText references a font; and in that case it is suggested you include a full description of the font with layouts.

A filter defines how to transform the objects it is attached to. The first byte is the filter type. The data following depend on the type. Because each filter is much different, they are defined in separate structures. You can attach a filter to an object using an ActionScript or the PlaceObject3 tag.

The following describes the different filters available since version 8.

DefineFontInfo

Tag Info
Tag Number: 
13
Tag Type: 
Define
Tag Flash Version:

Brief Description: 

Information about a previously defined font. Includes the font style, a map and the font name.

Tag Structure: 
struct swf_definefontinfo {
	swf_tag			f_tag;		/* 13 or 62 */
	unsigned short		f_font_info_id_ref;
	unsigned char		f_font_info_name_length;

		unsigned		f_font_info_reserved : 2;
		unsigned		f_font_info_small_text : 1;
		unsigned		f_font_info_reserved : 2;
	}
	else if(version >= 6 && f_tag.f_tag == DefineFontInfo2) {
		unsigned		f_font_info_reserved : 5;
	}
	else {
		unsigned		f_font_info_reserved : 2;
		unsigned		f_font_info_unicode : 1;
		unsigned		f_font_info_shiftjis : 1;

	}
	else {
		unsigned char		f_font_info_map[f_font_glyphs_count];
	}
};

A DefineFontInfo tag will be used to complete the definition of a DefineFont tag. It uses the exact same identifier (f_font_info_id_ref = f_font_id). You must have the corresponding font definition appearing before the DefineFontInfo since it will use the number of glyphs defined in the DefineFont to know the size of the map definition in the DefineFontInfo tag.

When it looks like it perfectly matches an existing system font, the plugin may use that system font (as long as no rotation is used, it will work fine.) It is also possible to force the use of the system font by declaring an empty ...

DefineFont

Tag Info
Tag Number: 
10
Tag Type: 
Define
Tag Flash Version: 
1
Brief Description: 

List shapes corresponding to glyphs.

Tag Structure: 
struct swf_definefont {
	swf_tag			f_tag;		/* 10 */
	unsigned short		f_font_id;
	/* there is always at least one glyph */
	f_font_glyphs_count = f_font_offsets[0] / 2;
	unsigned short		f_font_offsets[f_font_glyphs_count];
	swf_shape		f_font_shapes[f_font_glyphs_count];
};

It is common to use the DefineFont tag in order to create an array of shapes later re-used to draw strings of text on the screen. Note that the definition of the shape within a font is limited since it can't include any specific fill and/or line style. Also, each shape is assumed to be defined within a 1024x1024 square. This square is called the EM Square. Fig 1. below shows you the EM Square and how it is used. The characters baseline can be placed anywhere within the EM Square (it certainly can be outside too if you wish?!?).

A new concept: Throwaway Software.

More and more, people are learning new software as they go. A few will stick to one software for a long time simply because it is easier, but changing is easy too, especially if the new system is easy to use.

But how do you produce throwaway software? And is it worth the trouble?

As we see things evolving, more and more, people want to use software anywhere they go. This means software that runs on the Internet in some ways. For instance, you can use Google Map anywhere you go, as long as you have a computer to access the Internet.
