Frm format

[MutantenMeister]

Have you ever wondered why you can only see the characters from the back in the frmviewer?? I have envastigated a bit and here is my description off the frm format....

I'm also making a description off the dat format becasue there is only an russian description off it.

There are 4 viewers that support FRMs that I know, exclluding the mapper which also supports FRMs: GRV, frmviewer frmtobmp and RedViewer. The only oen I know which actually supports all FRM formats properly is my viewer (Red!Viewer)

Here's the structure (in VB):

Code: Select all

'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
' .FRM
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
' Header
Type FOFrameHeader
    ID As Long
    version As Integer
    triggerframe As Integer
    frames As Integer
    directionOffset(coordMax, 5) As Integer
    offset(5) As Long
    size As Long
    image() As FOSingleFrame
End Type

' Single frame data
Type FOSingleFrame
    hw(coordMax) As Integer
    size As Long
    off(coordMax) As Integer
    image() As Byte
End Type

When reading FoFrameHeader.offset() values from the file, if any of the values <> 0 then the image contains 6 directions. This value is actually the offset of the perticular direction within the file sterting from after the header. See http://www.duckandcover.net/forums/view ... 1859#41859
If you have any questions regarding parts of this don't hesitate to ask.

For my viewer I simply read the word at 4h and (for most animations it seems to be 8 not 6) so i simply read the numanims*numframes frames and they all seem to work correctly... do you have a copy off the webpage that aperared in the post you wrote about, it doesen't seem to exist anymore...
I have also an question on your sourcecode.. How long are the different datatypes you use and what does this coordmax mean?(i'm not an VB programmer...)

Well you might be right about 0x04h... I considered it a version as that's what all other docs refered to on the web. Or something like that anyway and never really looked into that number... I'll test that out with my viewer eventually.

As for coordMax itsn't just a constant (or define...) to... 1. It's just the value I use in my program to represent anything which should be coordinates, so that when coding with it the editor automagically offers me inline completion to either coordX/coprdY or coordHeight/coordWidth (as defined in my enumeration). Just my way of making clean code.

Long = 4 bytes
Integer = 2 bytes
Byte = 1 byte

Note that I have custom functions to read the Motorola values and convert them to Intel format, I don't just read them to memory...

As for the link it works fine for it. Note that it opens up in a new window so if you have one of those window-poper-protector programs (or disabled window poping in those browsers allowing that) it might not work so copy/paste it...

I will add your information to my description. With the link i meaned the link to the fortunecity page in the posting, not the posting itself.
