i can't remove the white background when saving as png or jpeg.
tried everything what suggested me on the web, but still get the diminsions i set up as whitebackground.
How can i save image without the background?
see image below for settings.
enter image description here
if you want to remove all the white from the picture, better go to color range and sample white. layer via cut and delete the layer. and save it in png as #cybernatic.nomad said, supports transparency.
Make sure you have created your image on a new layer and delete (or hide) the first white layer. I just created a simple text on a new layer with a transparent background and then loaded the image back into Photoshop to confirm that it works properly. As per previous comment I use .png format to preserve transparency.

When I'm inserting our company logo into Oracle Report there is a grey background on the logo. The logo is file type BMP, I have tried different file types like JPEG and TIFF as well. The issue still remains the grey background.
Below is the example of that grey background.
As you can see the portion which has the logo has a grey background whereas the background of the report is white. This is totally against our company guidelines and I've been told to find a solution for this. Please advise how can I remove the grey background.
Thanks
if you want to remove the background of the image then use an editing tool like photoshop and then remove the background and save the image as png then convert into bmp and then use it in your report.
I am using Lazarus.
I have put 2 images on a form and synchronized their positions and sizes.
I can textout to both images, and after I made the ontop image transparent I can see the combined content of both images.
I can add further text to the bottom image and see it, but I can't see text I try to add to the transparent image.
I used the following code to make the top image transparent
image2.picture.Bitmap.TransparentColor:=clWhite;
image2.transparent:=true;
I guess I need to play with the image bitmap, but I can't find a solution that is not using other software.
Can someone help me with this please?
I want to be able to layer images(PNG) with blank space over other images and have the images underneath still partly visible. right now my Image loading function will prints black space where it should have the background image.
As Noah mentioned, if your PNG images don't have an alpha channel, you can use LÖVE's blend modes.
https://love2d.org/wiki/BlendMode
Try displaying your image with "premultiplied", for instance.
love.graphics.setBlendMode("premultiplied")
love.graphics.draw(myImage)
love.graphics.setBlendMode("alpha")
"alpha" being the default blend mode.
So I have an image (GIF) with a blueish background and a circle (which i want to keep), I would like to remove the blueish background and ( or show the origin color of the back ground it sites on or make the background of the image totally transparent. )
Thank you .
This is GWT 1.6
GIF supports transparency also, open it in a image editor(not paint, it sucks) and select the background using the magic wand tool. Press delete and you're done!
PS: save it as GIF file if you have to..
This has nothing to do with GWT. The solution is to use PNG image format. PNGs allow you to specify a transparent background.
I have a dynamically generated PDF that can be in one of two modes. If in a draft mode, the only real difference is a watermark that states DRAFT on each page.
I am using a page event, so on the startpage I print the image, so that it is under everything. When I did this on the endpage event then it would be on top of everything, which was bad.
I would like to have alternating colors on the tables so that it is easier to see, but if I set the gray background to be 0.9 then it is opaque and the watermark is covered. If I set the background color to be null and the gray color is 1.0 then it is transparent.
So, my question is, on the non-white alternating rows can I get the watermark to be seen.
Ideally it would be nice to be able to place the image on top of the layer with the borders and background colors, so it would be under the text, but, it appears that isn't an option, as, when I use the stamp with the under content layer it would be under all the cells, since they all had colors set, so nothing was transparent.
UPDATE:
I haven't tried this yet, but it appears that if I save the PDF then using the PdfStamper I can save the graphics state, set the opacity for the image, then restore the graphics state, and it may work.

But, I don't see any way to do what I would like without saving it first, as I am actually generating and streaming directly to the browser, and would prefer not to save, if possible.
By using the link in my final update I was able to get the watermark to work.
So, I save the file, then I use a MemoryStream to read in the file and I save the graphics state, set the opacity, set the watermark and then restore the graphics state.
I then stream this back to the browser and delete the file.
I haven't found any way to do it that works better than this. What is nice is that an image is not needed for the watermark, so I set the font size to 96pts, and that seemed to work fine, in landscape and portrait mode.
