Before I go and file a bug report, I wanted to run an issue by everyone
here.
I am writing a tiny script to create thumbnails with images. In this
processes, there maybe some images that are to long, and readjusted by
height instead of width. Now to cut down on the amount of scripting I
am doing, I am resizing the image and pasting it into a a blank
thumbnail of proper size (I set the page to size all images by a width
of 300px).
I spent the better part of an hour pulling out my hair trying to get it
to paste an image together. I have come to the conclusion you can not
paste an image loaded from disk onto an image created in memory space.
as an example, I did the following:
<cfset blImage = ImageNew( width=300, height=270, type="rgb" ) > <!---
this is where I create my blank template --->
<cfset reImage = ImageNew( "#imageDir#/#arrFiles#" )><!--- this is the
image before resize from the disk ---><cfset thisWidth =
ImageGetwidth(reImage)>
<cfset thisHeight = ImageGetheight(reImage)>
<cfset ratio = thisWidth / 300>
<cfset newH = ROUND(thisHeight / ratio) >
<cfset newW = 300 />
<cfif newH GT 270>
<cfset newH = 270 />
<cfset ratio = thisHeight / 270 />
<cfset newW = round( thisWidth / ratio) />
<cfset error = ImageResize( reImage, newW, newH ) >
<cfset ImagePaste( blImage, reImage, 150, 150 )>
<cfset error = ImageWrite( blImage, "#imageDir#/t_#arrFiles#", "1",
"1")>
</cfif>
When I look at the image all it is, is a blank white square, nothing
pasted into it. And yes, I put to disk each image create at each
phase. IE, i tested newImage put a new image out by saving it, as well
as the image that is to be pasted into the new one.
However, what DOES work, is if you pull the blImage from the disk. Then
yes, you will be able to paste them together.
Bug? By Design?
