Merging two images (ASP)

Jimmeh · Post by **Jimmeh** » Tue Nov 25, 2003 7:46 pm

Hi,

I'm trying to use GFLAx to merge 2 gifs from within an ASP page. The problem I have is how to properly define the TYPE of AX_Image from ASP.

Is this possible? Or will I need to write a wrapper COM object to handle it?

Thanks

A new version of GFLAX will be available the next week, with merging feature.

I'm very .. I'm very want Merge method for ASP....

Maybe some simple function which Merge current image with only one other image?.... something as .Merge( filename, opacity, x, y) ... without any arrays & structures.... ????

Hello!

I've tried your code (after studying the help file) and it always returns "an empty object". I mean, if I try with applying date.gif to existing picture:

Code: Select all

Set sir = Server.CreateObject("GflAx.GflAx")
sir.EnableLZW = true
with sir
  .MergeAddFile Server.MapPath("pic1.gif"),40,0,0
  .MergeAddFile Server.MapPath("pic2.gif"),15,0,0
  .Merge
end with
' any object Method
sir.Crop 100,100,200,200 '<- this line

there comes to error with sir being "empty": GflAx.GflAx.1 error '80004005'
No file opened

Do I have to load an initial image? How to get and use the merged image?

Thank you,

Andy

Yes load a picture, or create a new one before merging

does this work with RGBA formats? e.g. TIFF or PNG with alpha-channel?

I want to use it for watermarking, but it doesn't seem to work.

I modified the "merge.asp" example as follows:

Code: Select all

<HTML>
<HEAD></HEAD>
<BODY>
<%

const AX_JPEG = 1

Dim Path, File

Set ctrl = server.createobject("GflAx.GflAx")
Path = Server.MapPath(".") 
File = Path & "\image.jpg"

With ctrl
	.EnableLZW = TRUE
	.MergeAddFile Path & "\img0.tif", 40, 0, 0
	.MergeAddFile Path & "\img1.tif", 15, 0, 0
	.MergeAddFile Path & "\img2.tif", 15, 0, 0
	.MergeAddFile Path & "\img3.tif", 20, 0, 0
	'.MergeAddFile Path & "\logo.png", 20, 0, 0
	.Merge

   .SaveFormat = AX_JPEG
   .SaveJPEGQuality = 70
   .SaveBitmap Path & "\result.jpg"
   
end with

set ctrl=nothing
%>
<IMG SRC="result.jpg">
</BODY>
</HTML>

But when I uncomment the merge command for "logo.png", the SaveBitmap command returns error '80004005' ("no file opened").

I've also tried with a TIFF instead, but same result.

Do I have to save in PNG or TIFF format, and if so, specifically what settings should I use when saving out of Photoshop?

Is merging with alpha-channel supported in the first place?

You can get my "logo.png" and "logo.tif" I use for testing here:
http://www.danline.dk/test/logo.zip

...

By the way, AX_JPEG was set to 3 in the provided example - which is wrong, according to the documentation the code for JPEG should be 1.

Ok, so don't use Merge, but DrawImage

that works, awesome! thanks!

oh, and here's the corrected code for placing the "logo.png" in the lower-right corner, on top of the image.

Code: Select all

With ctrl
	.EnableLZW = TRUE
	
	.LoadBitmap Path & "\logo.png"
	LogoW = .Width
	LogoH = .Height
	
	.LoadBitmap File
	.DrawImage Path & "\logo.png", .Width-LogoW, .Height-LogoH

   .SaveFormat = AX_JPEG
   .SaveJPEGQuality = 70
   .SaveBitmap Path & "\result.jpg"
   
end with
