In the Red, Green, Blue and Alpha text boxes, the left and right cursor keys are not operational making it somewhat difficult to edit the equations.

pyrochild, thank you so much for the help and advice.

For and effect I am envisioning, I would like to get a copy of the Source Image to display and manipulate in the Effect UI for later saving to the PDN window. Like Liquify does. All my attempts at getting the source image to a PictureBox have failed. Here is one of my attempts at getting the source image: protected override void OnSetRenderInfo(EffectConfigToken parameters, RenderArgs dstArgs, RenderArgs srcArgs) { if (firstTime){ // usually goes three times on the start of the effect?? MessageBox.Show("OnSetRenderInfo"); firstTime = false; PaintDotNet.Effects.FFPConfigDialog m_dlg = new PaintDotNet.Effects.FFPConfigDialog(); m_dlg.pictureBox1.Image = (Image)dstArgs.Bitmap; } base.OnSetRenderInfo(parameters, dstArgs, srcArgs); } This does not change the pictureBox1.Image, nor does anything else that I have tried. Later I need to get the transformed image to dstArgs.Surface. Any help appreciated.

I'm finding this plugin useful for one of my tasks - extracting frames from animated GIFs, modifying them and making a sprite sheet (PNG) of the frames for use elsewhere. I also tried to edit an animated GIF and save it as an animated GIF. The saved GIF did not use the original optimized palette and ended up with a dithered (lower quality) image. Is there any way to use the original optimized palette? I looked extensively through this forum. Here is my example: Click to enlarge PatrickL

FYI - I liked the Color Phase Shift effect and decided to try it in a Filter Factory format. (See null54's PdnFF in the Plugins - Publishing Only section) Works fine!! Save the following as "Psychocolor0.txt" and Load into null54's PdnFF: Category: Color Title: Psychocolor - Color PhaseShift Copyright: Freeware Author: Red ochre / [dpl port] R: put(r*D/255,0),128 + 127*sin(get(0)+ctl(0)*4)/D G: put(g*D/255,0),128 + 127*sin(get(0)+ctl(0)*8)/D B: put(b*D/255,0),128 + 127*sin(get(0)+ctl(0)*12)/D A: a ctl[0]: Phase Shift val[0]: 128 These kinds of calculation algorithms work nicely in Filter Factory format. edit1: updated to latest Red ochre equations. pleabo

This is a slightly different Color Replacement plugin. Another replace tool which might work better on some images. Color replacement is very image dependent, and different approaches work better on different images and even when it is pretty good, you may have to touch it up to your satisfaction. This one allows source color selection with either a cursor on a thumbnail of the image, or the using the primary color. Then selection discrimination can be with either Hue or RGB and there is a tolerance slider. The selected color may be made Transparent, replaced with a Solid Color or replaced with a Hue The selection can be Reversed. i.e. change the colors not selected If replacing with hue, the Intensity and Saturation can be modified with sliders The new color is selected with a color wheel Here is the User Interface: (Click to see full size) and some results: (Click to see full size) Works best on images with distinctly different colors. Unzip and place the DLL in the Effects folder. V1.0 DPL Color Replacement.zip and find Effects->Color->Color Replacement

I'm really enjoying playing with this plugin. My bride looks delightful with a Joker Grin and Elfin ears. Thanks pyrochild, PatrickL

Thought you might be interested. Polar checkered tiling by Werner D Streidt is one example TIA if you do. OK, OK, I'll leave you alone, PatrickL

Bruce, this plugin works with all of the WMF files I have tried. Very nice. The images always comes out the same size, sometimes smaller than I would like. Since these are vector commands, could they be made to generate the image to fit in the size of the currently open canvas? PatrickL

The pixel shift is fixed now I continue to be impressed with this integration of the GimpFF code with PDN. What a great way to get compatibliliy. Some more comments: The d dependent constant is PI radians off from GimpFF causing a few different outcomes importing 8bf filters. (Click for larger image) WBNI if when editing the equations, the up/down arrow keys would cycle through the 4 equation text boxes. When getting to more complex equations, the processing becomes larger multiple seconds and starts to feel sluggish when revising the equations, or changing slider values. WBNI changes could be locally in the dialog window on a smaller copy of the underlying image, say 320 pixels wide and then processed (slower) on the fullsize PDN image on OK click. This scaling smaller can be done just by scaling x,y,X,Y,m,M to the image ratio to get the same looking results. PatrickL

While browsing, I saw a few references to procedures to create a "Night Vision" look to an image. This is a simple plugin to directly create a Night Vision and Inverted Night Vision look. Also an intensity control slider. Just a simple application of the Green Channel = (r*0.2+g*0.6+b*0.1) while Red=Blue=0. DPLNightVision.zip Unzip to the .../Paint/Effects folder. NightVision will be in the Color section. The User Interface: The Result: PatrickL

Thanks Possum and Oma. I've seen both or your artwork, and since I'm artistically challenged I'll be looking forward to seeing what you all can do with this idea. PatrickL

Bingo! Thank you. Now I can have some fun. PatrickL
