Draw text interline

Hello,

I have used the DrawText function and remark that the interline spacing is quite large.
Is there a way to set/specify it ?

Thanks

Combine with transparency

Hi, Is there a simple way to combine an image, which has some transparencies, with another one ? Just imagine ImageA.png with some transparent areas. ImageB.jpg a normal image. (ImageA + ImageB) will be ImageA and instead of transparency, we see parts of ImageB ( Like a layer in Photoshop ). It simu...

Re: LUT Look Up Table

Hello, Here is my proposal solution to code a LUT function. Tell me if you find an optimization on it: public void ApplyLut(int[] lookupTableRed, int[] lookupTableGreen, int[] lookupTableBlue) { int imageWidth = _gdPictureImaging.GetWidth(_image); int imageHeight = _gdPictureImaging.GetHeight(_image...

Image Mask combine

Hello, I'm migrating from LeadTools to GDPicture, and I'm looking for an equivalent of FeatherAlphaBlendCommand : Combines image data from two images with feathering. The two images can be combined with variable opacity applied by specifying the region of a fade mask image. It's useful to merge an i...

LUT Look Up Table

Hello,

Is there a way to apply a LUT ( Look Up Table ) by passing Red, Green and Blue arrays ?
I didn't find a function to achieve that directly.

Many thanks.
Kind regards,
Frédéric

Re: Cloning issue

Hi, The CreateClonedGdPictureImage will create a new Id for a copy of the picture but using the same GdPictureImaging object ? If I instantiate a new GdPictureImaging, will this new Id can be used to retrieve the picture ? Is this new Id independant of the GdPictureImaging instance ? Many thanks Kin...

Mask region

Hello,

Is it possible to select a region from a point by selecting a range of color ? Like a magic wand ?
And after this to make this region transparent ?

Thanks
Kind regards

Changing bit depth

Hello, I looking for an equivalent of LeadTools command "ColorResolutionCommand". This function is used to change the bits per pixel of an image. Is it possible with GDPicture ? Here is the LeadTools call: ColorResolutionCommand cmd = new ColorResolutionCommand(); cmd.Mode = ColorResolutionCommandMo...

Cloning issue

Hello, I have created a class which embed a GdPictureImaging as member and a "int" for image Id. I wanted to implement the ICloneable interface in order to create a new instance of my class. My problem is how to achieve this clone that will duplicate the GdPictureImaging and the associate image id. ...

Re: JPEG Thumbnail

Hello, Well, I use the following code: GdPictureImaging imaging = new GdPictureImaging(); int id = imaging.CreateThumbnailHQ(image.MediaPath, 0, 0, imaging.ARGB(255,255,0,0)); imaging.SaveAsBMP(id, thumbnailPath); imaging.ReleaseGdPictureImage(id); It works, but it generates a thumbnail instead of g...

Re: JPEG Thumbnail

Hi Loïc, CreateThumbnailHQ doesn't seem to "only" read the embedded thumbnail. First, we have to load the image to get imageId, then call the CreateThumbnailHQ. These operations takes too much time. Normally an extraction of embedded JPEG takes around 15 milliseconds which is not the case here. More...

JPEG Thumbnail

Hello,

I wanted to load the embedded thumbnail of a JPEG image as fast as possible. I didn't find a way to do it. Indeed, CreateThumbnail and Create ThumbnailHQ seem to load the complete image and resized it, so it's not very efficient. Can someone guide me on how to do that ?

Many thanks.
Frédéric.
