This page will explain how to...
- Place limits on the maximum pixel dimensions of the
signature so that images that are too large in dimensions will be
automatically cropped. (Part I)
- Filter out images out of signature based on the file size of the images. (Part 2)
Part I Limiting Signature Dimensions
If a user has a signature that is too large in dimensions, it can mess
up the screen. The ideal solution would be to create a div container
for the signature so that the div stretches until a set limited, after
which it stops stretching and crops the signature. In V8.x of
webwizforum, a "max-height" property was added to the div container of
the sig. However, "max-height" is not a functional property in IE, and
at least in version 8.01 which I use, this error has not been fixed. In
order to implement max-height in IE, a workaround has to be used.
How to implement the MOD:
Open the stylesheet of the mod. Most likely, this will be css_styles/default_style.css. Insert or modify the existing code to the lines shown in red and blue into the .msgSignature.
Code in css_styles/default_style.css that needs to be inserted/modified
-----------------------------------------------------------------------------------------
.msgSignature{
max-height: 160px;
width: 600px;
height:expression(this.scrollHeight > 160? "160px" : "auto" );
}
-----------------------------------------------------------------------------------------
Result: All text/images beyond 600x160 will be cropped. The
signature will automatically shrink to fit if the signature is smaller
than 600x160.
NOTE: In this example, only the vertical height is dynamically
controlled. In order to dynamically control the width, a similar
expression needs to be replicated for the width. However, in most
cases, a fixed horizontal width is good enough because it is not
necessary to dynamically "shrink" the width, unlike with the height.
Summary of the code:
Since IE does not recognize the "max-height" property, a workaround
involving "expression and this.scrollHeight" must be used. This line,
shown in blue has essentially the same effect as "max-height," but is
recognized by IE.
To customize the maximum height of the, change 160 to whatever you want it to be. To customize the maximum width, change "width: 600px" to whatever you want it to be.
To remove the scrollbars on the signature, line 696 in
functions/format_post.asp has to be modified. Change the overflow from
"auto" to "hidden" as shown in red.
Line 696 in functions/format_post.asp that needs to be inserted/modified
-----------------------------------------------------------------------------------------
vbCrLf & " <div class=""msgSignature"" style=""float:left; overflow:hidden;"">" & _
-----------------------------------------------------------------------------------------
Part II Limiting the file sizes of images in signatures
While the above code would limit the dimensional size of
signatures, it doesn't limit the file size of images in the signature.
To do this, a more complicated code needs to be written.
How to implement the MOD:
Insert the additional code into register.asp as shown:
Code in register.asp, showing starting from line 323. Insert only the code in blue/red in the exact location as shown. Do not modify anything else.
