[jira] Created: (OFBIZ-2552) Image scaling quality

Nicolas Malin (Jira)
Image scaling quality
---------------------

                 Key: OFBIZ-2552
                 URL: https://issues.apache.org/jira/browse/OFBIZ-2552
             Project: OFBiz
          Issue Type: Improvement
          Components: framework, product
    Affects Versions: SVN trunk
         Environment: linux Debian, trunk revision 779985
            Reporter: Eric DE MAULDE
            Priority: Minor
             Fix For: SVN trunk


We can improve image scaling quality with an other JAVA algorithm

Comparison of different JAVA image algorithms
http://www.hanhuy.com/pfn/java-image-thumbnail-comparison

the algorithm with the best quality is AWT SCALE_SMOOTH

[jira] Updated: (OFBIZ-2552) Image scaling quality

Nicolas Malin (Jira)

     [ https://issues.apache.org/jira/browse/OFBIZ-2552?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Eric DE MAULDE updated OFBIZ-2552:
----------------------------------

    Attachment: scaleImage.patch

this patch use the AWT SCALE_SMOOTH algoritm to scale an original image

the code example of the comparison author uses JAI Api (2nd page).
But OFBiz doesn't implement JAI ?
So I haven't used his example

Now into the file ScaleImage.java
I don't use anymore interpolation code (from the line 165 "Double scaleFactorDb" to the line 193 "return result;}"

if it's better, I can delete the interpolation code into the patch

Eric,

You have still an interrogation ("If it's better"), or do you think it's better ?

---------------------------------------

Jacques,

Sorry my explanations weren't understandable
Into a new patch I go to delete lines about interpolation,
because this class doesn't use any more this code.
