Currently i am working on excel vba based printing program.I need only certain cells(not areas) to be a print object.I know excel does not have such a function.So i thought using a png image that has transparent background.My reason to do this making active x image non printable.Active X image does not allow me to use png files.
Do i need special codes to allow me to use png images?
Not sure I got it right (sorry) but why don't you just insert the png image through the Insert>Image? and then uncheck its "Print object" property?

I am new to handling graphics and would appreciate some help.
I purchased this particular EPS and trying to edit it.
I am using Vectr for handling EPS/SVG, however, Vectr was not able to open this EPS (bought from iStock).
Tried Gravit and it failed too. Then I converted the EPS to SVG, using an online converter.
This is the graphic I am dealing with:
I just want to remove the checkered background. When I opened this SVG in Gravit, the background shows as a path. There are a large number of paths in this graphic.
Could someone advice on how to remove this checkered background using a SVG editor like Gravit.
Thank you.
You need to use one of these graphic editors: Corel Draw or Adobe Illustrator. You can send the file to me, I will send it to you without a background. kuznetsovasasha86#gmail.com
This question is very similar to PDF image in PDF document using ReportLab (Python), but I seem unable to adapt it to my needs:
I want to add vectorized images (available in SVG oder PDF format) to an A4 PDF output. The images must not get scaled! They should simply be placed from top to bottom with some vertical spacing and automatic page breaks.
No text or other content is required. Basically, I'm looking for a pdfnup solution. In the past, I have used pdflatex with a simple input file for the task, but this is no option for the target system.
I tried to export a standard SO form to pdf and as I check in it the logo/image looks like its been corrupted, as I look it in the report designer there seems no problem except that the cause might be on the Barcode Type. I just want to export it to PDF with a clear logo/image.
HELP.
The report engine has issues with transparent colors when exported. Any Transparent color comes out black when exported to PDF.
The easiest thing to do is to download your image, open it in an editor (even paint will work) and replace the transparent color with white.
I would like to know if there is a way use the built in export/getSVG function in Highstock to save the exported PNG to a variable in the background instead of prompting the user to download the file.
The thought is for a user to be able to click a button which will export each snapshot to a variable in the background. When done scrolling through the entire chart a subsequent button would create a document containing all the PNG images for a singe download. We can develop everything but the hangup is on saving the PNG image to a variable. We have been able to assign the SVG string to an array we maintain but due to size this would not be the best option for use.
Are there any ways to do this?
Something like this is possible to achieve, see FAQ
However, there is also one more option - get SVG, and use canvg to render into canvas and then to PNG file, as you need.
I have some .bmp files that have some color (maybe black) that is supposed to show as transparent when the graphic is displayed on top a form, so the form color comes through the transparent areas. But by default, when I put these images in an Image View, the black/transparent areas show up as BLACK!
I'm thinking I need to either:
- alter how the NSImageView shows the image, so that a certain color is transparent, or
- modify the .bmp files somehow to make that color suitable for transparency in an NSImageView
But I don't know enough about graphics files, transparency(alpha), NSImageView, nor the image editing tools. I'm trying to use Gimp, but...not sure what I'm doing yet. It seems like there is already a color that should be transparent in the current .bmp file.
I'm sure its something simple for setting NSImageView, or editing my file, or perhaps making a mask for the image, but I don't know how yet. I've looked at various filters in IB for NSImageView, but have not found where to set the transparent color, nor how to grab that color from the image file to make sure I use the correct value.
Thanks in advance for any assistance. (I tried to post some images, but because I'm new, I could not.)

I'm not a Cocoa developer, but in Gimp try adding an alpha channel to your image (a layer mask, perhaps) then saving as a 32-bit PNG image (with an alpha channel), then load that PNG directly into your NSImageView. If you want to make the black pixels transparent in Gimp use the magic-wand tool to select them (use magic-wand with 0 tolerance) and just delete the contents of the selection then save as a PNG directly.
