I would like to create an Automation plug-in to communicate to a Filter plug-in to get information (includes: start address, data size, height, weight...) of picture which is displaying on Photoshop window. But right now, I don't know the way to do this.
Does Photoshop SDK support to do this? Please help me.
Yes, see the automationfilter and hidden examples.<br /><br /><br /><Hieu_Nguyen@adobeforums.com> wrote in message <br />news:3bc45199.-1@webcrossing.la2eafNXanI...<br />>I would like to create an Automation plug-in to communicate to a Filter <br />>plug-in to get information (includes: start address, data size, height, <br />>weight...) of picture which is displaying on Photoshop window.

There are two versions of the automationfilter + hidden example.<br /><br />The first one, I think version 6 or 7 of the SDK. Had the following <br />workflow.<br /><br />1. AutomationFilter allocated memory for the pixel data<br />2. AutomationFilter did the PutInteger as you describe below and called the <br />Hidden filter<br />3. The HiddenFilter got the pixel data and copied the information into the <br />pointer and exited<br />4. The AutomationFilter changed the pixel data and then called the Hidden <br />filter again<br />5. The HiddenFilter wrote the pixel data via the filter callbacks.<br /><br />This is VERY inefficient and breaks down quickly on large documents.<br /><br />The next generation of the AutomationFilter and Hidden example is what is <br />currently in the SDK.<br /><br />1. AutomationFilter determines which commands to send to the Hidden filter<br />2. The Hidden filter executes the filter operation in entirety.<br /><br />In this mode there is no passing of pixel data back to the automation <br />filter. All pixel munging is handled in the hidden filter and all the <br />automationfilter does is send the correct command to the hidden filter.<br /><br /><Hieu_Nguyen@adobeforums.com> wrote in message <br />news:3bc45199.1@webcrossing.la2eafNXanI...<br />> Dear Tom Ruark,<br />><br />> In AutomationFilter project, I see API that get pixelData like this:<br />><br />> error = sPSActionDescriptor->PutInteger(descriptor,<br />> keyPointer, (int32)pixelData);<br />><br />> Is this the API to get the starting address of image in memory?<br />><br />> Thanks,<br />><br />> Hieu Nguyen.
Now, we still don't know whatever parameter is used to get start address of picture in the automationfilter and hidden examples. Can you help us?
Thanks
