ID: 43508 Updated by: [EMAIL PROTECTED] Reported By: vbhunt at silverfox dot com -Status: Bogus +Status: Feedback Bug Type: GD related Operating System: Windows XP Professional Ver 2SP2 PHP Version: 5.2.5 Assigned To: pajoye New Comment:
"Both ImageReady 7.01 and Photoshop 7.01 show alert.png as having an opacity layer with 0% opacity (i.e. 100% transparency) that covers the rectangle not covered by RGB pixels." Exactly, there is not transparent color set but a white color with 100% transparency. The alpha channel is correctly read and the resulting image can use it correctly. Take the "alert.png" image, the top left pixel is transparent (at 0,0), using a white color with 100% transparency but it is not the bgd color. Or am I still missing your point? Previous Comments: ------------------------------------------------------------------------ [2008-11-03 00:55:18] vbhunt at silverfox dot com This is NOT a bogus bug. Both ImageReady 7.01 and Photoshop 7.01 show alert.png as having an opacity layer with 0% opacity (i.e. 100% transparency) that covers the rectangle not covered by RGB pixels. No alpha channels are shown in either ImageReady or Photoshop. Every single one of the submitted test images properly display with proper png transparency in both IE7 and Firefox3 as well as ImageReady 7.01 and Photoshop 7.01 as was originally reported. Yet the ImageCreateFromPNG function cannot find this transparency. Therefore I continue to conclude that this is NOT a bogus bug. Can you demonstrate any working example that preserves transparency using ImageCreateFromPNG? I suspect not. I have provided you with many examples that cause this function to fail, yet have clear transparency as shown in both the development and display tools. ------------------------------------------------------------------------ [2008-11-02 18:30:25] [EMAIL PROTECTED] There is no transparent color (or known as background color). The alert.png for example uses the alpha channel, and the borders of the images is filled with the white color and 100% alpha. A png image can use either the alpha channel or the transparent color but not both. ------------------------------------------------------------------------ [2008-11-02 18:15:25] vbhunt at silverfox dot com Sorry, permissions were changed in a security sweep.
