Can this Tiff Loader be updated to use your plugin Open dialog with TIF as the only choice?

Code: Select all

var fso = new ActiveXObject("Scripting.FileSystemObject");
var util = System.CreateDO("Clintons3D Package/Utility functions");
var folder = "";
var filename = "";
folder = fso.GetParentFolderName(filename);
filename = fso.GetFileName(filename);
//fso method return of folder or filename is flawed when path is invalid/empty
//causes returned value of plugin to cause tS crash
if(folder=="") folder="";
if(filename=="") filename="";
//var defExt = "tga";
//var filter = "TGA (*.tga)~*.tga~EXR (*.exr)~*.exr~HDR (*.hdr)~*.hdr~Jpeg (*.jpg)~*.jpg~PNG (*.png)~*.png~TIF (*.tif)~*.tif~All Files (*.*)~*.*~~";
var defExt = "TIF";
var filter = "TIF (*.tif)~*.tif~All Files (*.*)~*.*~~";
var file = util.FileOpenDialog(folder, filename, filter, defExt);

The Tif Loader.RsObj has a Filename attribute
Not sure how to remove All Files and populate the Filename attribute with the returned path

New button added.

The way you wrote the popup you are limited to 1 tiff file in the scene, so if you want more than 1 you have to rename the node before loading another one.

Thank you!
I tried removing the popup's Node.Delete, but I find, since multiple copies share the one Panel Frame, there is multiple copies left over in the scene
Do you have a better suggestion?
Couldn't a user Load and Save images from the same panel?
I tried using your plugin's Save As Dialog (v2) for trueSpace, but failed miserably!

I don't know how you're planning to use it, so no I don't have any suggestions. Don't even know why it's a popup.

Save as images has limited file formats, bmp, dds, hdr, jpg, png, dib, pfm.

Attached has working Save as Dialog(v2)

The popup is for users that have Link Editor phobia

I take it, that you use it for importing and linking tif images to other bitmaps in the Link Editor?
That is still possible

There was an issue when switching to png in the dialog, it would not switch to png
Also, the File name: in the dialog was the name of the imported tif
IE: File name: MyImage.tif
When you save it that way, even though the dialog's Save as type: was bmp, the file saved is not good
So I added one line:
filename = "Image"
Here is the changes:

Code: Select all

var Filename = Node.Value("%THIS_NAME%", "Filename")
if(Filename == "") {return;}
var fso = new ActiveXObject("Scripting.FileSystemObject");
var util = System.CreateDO("Clintons3D Package/Utility functions");
var folder = "";
var filename = Node.Value("%THIS_NAME%", "Filename");
var defExt = "bmp";
var filter = "BMP (*.bmp)~*.bmp~DDS (*.dds)~*.dds~HDR (*.hdr)~*.hdr~Jpeg (*.jpg)~*.jpg~PNG (*.png)~*.png~";
filename = "Image"
var file = util.FileSaveAsDialog2(folder, filename, filter, defExt);
if(file) Library2.DlgGenericSave(file, "%THIS_NAME%/Image", 3);

It seems to work, unless you see something that is not correct
One thing to note is I omitted one Tilda ( ~ ) at the end
.

From the original Save As Dialog, uses "~" as a delimiter between the description and the extension and end the string with 2 ~'s

So removing the extra ~ maybe it's ok or maybe it create problems later. I wouldn't take the chance.

It would be simpler to change the line

var filename = Node.Value("%THIS_NAME%", "Filename");

to

var filename = "";
or
var filename = "Image";

Thanks, I added the extra ~
One way I was using your TIF Loader is in YafaRay4tS as a TIF Viewer

Just noticed that this does not show/open tiff images only tif
Edit: I fixed it
var filter = "TIF (*.tif)~*.tif~TIFF (*.tiff)~*.tiff~~";
Is the a way to show/open both in the File type

Good question. Had to look it up. You use semicolon to list them

var filter = "TIF (*.tif;*.tiff)~*.tif;*.tiff~~";
the first half is displayed and can be anything you want - "TIF (*.tif;*.tiff)"
second half is the actual filter "*.tif;*.tiff"

Cool!

Thank you again!

Update October 2024

added support for EXR files to the plugin.

I found that tS HDR image save is not high quality. It gives a wider range of colors but seems to keep discrete step values like an LDR image. It's strange and difficult to explain, maybe it's rounding the values?. This EXR save command keeps the quality of the color values of the image. The only real way to see the difference is to save a HDR format smooth image and compare it to the EXR image and see how the values jump in the HDR compared to the EXR image.

The EXR loader was tested with images from here:
https://openexr.com/en/latest/test_images/index.html

The loader does not support the pxr24 or b44 compression

When saving an exr with alpha channel it won't load back into tS properly. The color channels get scrambled. The really weird thing is if you open the image in another app it looks just fine. So if you load an exr image with alpha it looks good. Then you save it with alpha it looks bad in tS but identical to the original in other programs. There is a checkbox to unscramble the colors when using the loader.

Can you help with the Save As button code?
And anything else you see that maybe wrong.

Removed the image node
Connected internal Exr Loader Bitmap to the Image Information
Save As button saves %THIS_NAME%

This also reminds me that I forgot to add the loaded filename into the Bitmap data, so one more rsx change coming...

clintonman · Post by **clintonman** » 24 Oct 2024, 23:43

I updated the rsx plugin to version 1638417
The only change is that the filename of the image will display when running the script command that reads it.

SDK docs:
HRESULT IRdBitmapDisp::GetFileName ( [out, retval] BSTR * pFileName )

I just found out the EXR Loader isn't needed. tS will load exr files just fine. It just wont save exr files.
