Hello, When I load a custom file, I parse it and get a string from it. Then I would like this string to appear in a textbox in the Save dialog... but no matter what I try, it doesn't work: I read the string from the file successfully, I can set the Title of the textbox, but not it's Value :S private enum PropertyNames { TextBox_ArrayName, } string arrayName = "array_name"; public override PropertyCollection OnCreateSavePropertyCollection() { List<Property> props = new List<Property> { new StringProperty(PropertyNames.TextBox_ArrayName, "array_name") }; return new PropertyCollection(props); } public override ControlInfo OnCreateSaveConfigUI(PropertyCollection props) { ControlInfo configUI = CreateDefaultSaveConfigUI(props); configUI.SetPropertyControlValue(PropertyNames.​TextBox_ArrayName, ControlInfoPropertyNames.DisplayName, "Give a name to the array:"); // I can do that to confirm that arrayName is successfully read from the the file: //configUI.SetPropertyControlValue(PropertyNames.​TextBox_ArrayName, ControlInfoPropertyNames.DisplayName, arrayName); //Doesn't work //PropertyControlInfo pci = configUI.FindControlForPropertyName(PropertyNames.​TextBox_ArrayName); //pci.Property.Value = arrayName; //Doesn't work //props[PropertyNames.​TextBox_ArrayName].Value = arrayName; return configUI; } protected override Document OnLoad(Stream input) { ... arrayName = "name_from_file"; ... } protected override void OnSaveT(Document input, Stream output, PropertyBasedSaveConfigToken token, Surface scratchSurface, ProgressEventHandler progressCallback) { ... arrayName = (string)token.GetProperty(PropertyNames.​TextBox_ArrayName).Value; ... } I have tried other things but no luck... What did I do wrong?

Ok well I give up, the plugin wil not support loading. Thank you anyway

Hello, I have an issue with a filetype plugin I am writing. I need to show a dialog with 2 textboxes when opening the file, and I will enter the size of the image in those textbox, because the size can't be found in the file (only raw pixel data). How could I do that ?

How can I change the extension of the file when saving? For ex if encoding method 1 is used, set extension to ".xg1", etc... Is it possible?

Sorry midora I don't understand what you said... But no problem, the code is still very fast, load/save speed isn't an issue at all. Meanwhile I have made a lot of progress, I have added an optional RLE-like algorithm (2 versions of it), this was easy to make and works quite well, sometimes produce a smaller file than equivalent 24bits PNG. Actually I'm making tests to see what is the best compromise filesize/code speed (these are images that will be loaded on a small TFT display controlled by an Arduino, I'm making a GUI library for it). But I would like to make an option "Autodetect" in the Save dialog, that will test some output modes (ex: with or without RLE v1, or v2...), and choose the one that makes a smaller file. Similar to the PNG Save dialog I guess. How can I do that, is it at least possible with plugins? Edit: auto detection done

Very useful, thanks

Hello again, Nice to know that we can save layers separately, even if I don't need it actually So I managed to make a plugin that can save and load the custom format, which is great news (actually, just RGBA8888 but I don't have problem converting from/to my custom format "RGBA5658") Basically: protected override Document OnLoad(Stream input) { // The 4 first bytes of the file are the size of the image in pixels UInt16 sizeX = (UInt16)( (input.ReadByte() << 8) | input.ReadByte() ); UInt16 sizeY = (UInt16)( (input.ReadByte() << 8) | input.ReadByte() ); Bitmap bmp = new Bitmap(sizeX, sizeY, PixelFormat.Format32bppArgb); for (int column = 0; column < sizeY; column++) { for (int row = 0; row < sizeX; row++) { byte r = (byte)input.ReadByte(); byte g = (byte)input.ReadByte(); byte b = (byte)input.ReadByte(); byte a = (byte)input.ReadByte(); bmp.SetPixel(row, column, Color.FromArgb((int)((a << 24) | (r << 16) | (g << 8) | ); } } return Document.FromImage(bmp); } protected override void OnSave(Document input, Stream output, SaveConfigToken token, Surface scratchSurface, ProgressEventHandler callback) { //BinaryWriter binWriter = new BinaryWriter(output); input.Flatten(scratchSurface); UInt16 sizeX = (UInt16)input.Width; UInt16 sizeY = (UInt16)input.Height; output.WriteByte((byte)(sizeX >> 8)); output.WriteByte((byte)(sizeX & 0xFF)); output.WriteByte((byte)(sizeY >> 8)); output.WriteByte((byte)(sizeY & 0xFF)); for (int row = 0; row < scratchSurface.Height; row++) { for (int column = 0; column < scratchSurface.Width; column++) { ColorBgra bgra = scratchSurface[column, row]; output.WriteByte(bgra.R); output.WriteByte(bgra.G); output.WriteByte(bgra.; output.WriteByte(bgra.A); //binWriter.Write( packRGBA8888(bgra.R, bgra.G, bgra.B, bgra.A) ); } } //binWriter.Dispose(); } It works well enough for now, I'm just wondering if there is a better/faster way of doing the Load(). Any tips? Also another questions: What is the difference between OnSave and OnSaveT ? Does scratchSurface.Height and scratchSurface.Width always equals input.Height and input.Width ? Thanks.

Hello midora, thank you for this. At least a start, let me try some things Edit: I only did that for now as a quick test: output.WriteByte(bgra.R); output.WriteByte(bgra.G); output.WriteByte(bgra.; output.WriteByte(bgra.A); And it worked... I can't believe how easy it was (but I couldn't have done it without your code)

Hello all, I need to make a FileExport plugin which export into a custom format, that is a binary file with 24 bits per pixel: 16 bits for RGB565 and 8bits for the alpha channel. No metadata, no header, just an array of bytes. The big problem is, I have absolutely no idea how to do this... I saw some sample plugins but they all look simple (even if I don't understand most of the code...), using things like: PixelFormat.Bgr565 or PixelFormats.Bgra32. Obviously my custom pixel format isn't in the list. For now, I just would like an example how to get pixels RGBA colors inside the OnSave(T?) callback. Then I can try myself to convert it to the format I need. And then I will probably come back here to ask other questions about how to actually write in the output file. You guessed, I am totally lost... Any help appreciated!

I solved the errors and made it compile, but being new to C# and never used bitmap etc functions, I'm lost at what to do next... I will ask few questions in the development forum.

Have you tried it? Because it doesn't even compile. It's almost 6 years old. After hours of searching I finally found a source code of another export plugin, it compiled and worked. But it didn't help a lot since what I want to do is totally different, which is why I would like the source code of this particular plugin since it is almost exactly what I want to do: export an array of RGB565, but with an additional byte for each pixel, that is the pixel's transparency.

Hello, any chance that you share the source code? I would like to write a custom export format but I need some example plugin. Thanks!

One week later, almost 200 views and not a single reply, this forum is useless.

Hello all, I have a problem with a font in PDN. The font work normally in Photoshop, but in PDN it doesn't. The font is called HelveticaNeueBd.ttf. I tried to download it from 2 different websites, here is one: https://bedita.googlecode.com/svn-history/r1379/trunk/vendors/phpThumb/fonts/HelveticaNeueBd.ttf Here is how it appears in PDN's font browser: So, the V letter is working...but that's about it, few other also work, some in lower case, some in upper case, some punctuations... When I write characters which doesn't work: with anti aliasing enabled, it will add some space (the width of the characters), and with anti aliasing disabled, it doesn't add any space, it's like I wrote nothing. Also, if I double click the font file, it opens in that Preview window and all characters are working normally as expected since the font works normally in Photoshop.. but I don't like Photoshop. Any idea how to solve the problem? Thanks in advance for any help Edit: well it was urgent job so I did it with Photoshop, but I'm still interested if you have a solution.

No but problem solved, the whole thing was wrong because I used values between 0 and 255 when I should have used values between 0 and 1. Thanks anyway
