Reading variations in a .PCX file
Posted on 1998-07-30
I apologize for my numerous postings on this subject.
I've tried to illustrate my concept a little better by posting a representation of the file I am trying to work with.
What I need to do is, once I have the PCX file loaded in, I need to be able to extract a "frame" from the PCX file itself. For example, if the file is 36 by 180, and I wanted to get the SECOND sequential 36 x 36 block I would need to go to coordinates 0,36 | 36,72....like this:
THIS IS ONE CONTINUOUS COLLECTION OF 36 x 36 pixel squares. The dimensions of the entire image are 36 x 180 pixels for a total of 5 variations or "frames" going vertically. If you we're to look at the .PCX file in MSPaint it would look like this:
SAMPLE.PCX
XXXXX
X X
X X <-Variation 1
X X
XXXXX
X X
X X <-Variation 2
X X
XXXXX
X X
X X <-Variation 3
X X
XXXXX
X X
X X <-Variation 4
X X
XXXXX
X X
X X <-Variation 5
X X
XXXXX
How would I extract Variation # 2?
I am VERY new at this, so I will require a FULLY FUNCTIONING procedure or function that I can just paste into my code and away I go.
The source code is available upon request. Just send me mail at knowltonfamily@yahoo.com

Hi, Tom!
This is me.
What happened to the code I've sent to you?
Is it working or you didn't receive it?
If you didn't receive it I can send it again.
Also you can LOAD your .PCX file into TImageList (all you need to do - set up Properties: Height and Width to 36, then it will load it up correctly itself).
Thanks, Andrey.

what could do is load the image into an invisible TPCXBitmap, or whatever you want and then use a TRect like so...if you know the size of the image...I mean the dimsensions of the image..you could use something similar to this...
procedure ExtractFrame(Row: Integer);
var Rect : TRect;
begin
Row := 180 div 36;
with Rect do
begin
Top := Row * 2;{Multiply the Row with the row #...if you want to extract frame #2 then use Row * 2}
Bottom := Row + 36;
Left := 0;
Right := 36;
//Now here use Canvas.CopyRect() or BitBlt to copy Rect to the place you want on your //visible canvas...
end;
end;
I hope it helps a bit!

Viktor Ivanov

Viktornet:
Thank you for your response.
I will NOT know how big the file is until runtime...that's the problem.
Also, if you provide a source code solution I need you to post a function that I can just drop into my program and away I go...
If you want to send my source code back to me with a new function that does what I want, that would be the preferred solution.
Thank you,
Tom

knowIton, what do you think about the piece of code I gave you above, do you think it can help you a bit? :)

Ok, I'll try to make a function/procedure but I need you to tell me where do you need the frame extracted image to be placed...???
Viktor Ivanov
Viktor Ivanov
Do you wanted to be placed in the Image which is named ImageThumb...the small image on the top???

Viktor:
Yes, you can put it into ImageThumb...that would be perfect.
Also, I suppose I should put the frames into some kind of TImageList. For example, if the .PCX file had 5 frames, the TImageList would contain 5 images, each one would be 36 x 36 pixels.
I sure appreciate your help!
Tom
btw - What do you think of my code? Is it pretty stupid or is it okay?

Hey, KnowIton, I've made exactly what you need...I forgot your E-mail address, would you please leave a comment with the e-mail please...What I've done is that I've created a procedure to extract the frame you want from the image...it's so easy to use , just like this...
ExtractFrame( 0 , 0 , Invisibe_lImage_That_Conta
{That will extract the first frame of the Source Image and place it in the ThumbImage}
Just let me know your E-mail and I'll send you the procedure and a demo app..OK???
Regards,
Viktor Ivanov
That's all you need to write...I didn't try it on your project but I'm sure it will work...

Opps....Sorry, Your e-mail is on the top of this page....I'll send you the source code and please tell me if that;s exactly what you needed, so I can use it too in the future...OK???

Well, tell me what you think knowiton... Did you recieve my mail with the Source Code I sent you???

Yes, this code did work. Now my problem is getting it to integrate with the Map Editor.
I am going to give you the points, but could you still help me integrate the code into the Map Editor itself? I'm still having trouble there.
Thanks,
Tom
